81 <!-- INTRODUCTION -->
82 <h2 id="intro">Introduction</h2>
84 <p> phpMyAdmin can manage a whole MySQL server (needs a super-user) as well as
85 a single database. To accomplish the latter you'll need a properly set up
86 MySQL user who can read/write only the desired database. It's up to you to
87 look up the appropriate part in the MySQL manual.
88 </p>
90 <h3>Currently phpMyAdmin can:</h3>
92 <ul><li>browse and drop databases, tables, views, fields and indexes</li>
93 <li>create, copy, drop, rename and alter databases, tables, fields and
94 indexes</li>
95 <li>maintenance server, databases and tables, with proposals on server
96 configuration</li>
97 <li>execute, edit and bookmark any
98 <abbr title="structured query language">SQL</abbr>-statement, even
99 batch-queries</li>
100 <li>load text files into tables</li>
101 <li>create<a href="#footnote_1"><sup>1</sup></a> and read dumps of tables
102 </li>
103 <li>export<a href="#footnote_1"><sup>1</sup></a> data to various formats:

132 <h4>A word about users:</h4>
133 <p> Many people have difficulty
134 understanding the concept of user management with regards to phpMyAdmin. When
135 a user logs in to phpMyAdmin, that username and password are passed directly
136 to MySQL. phpMyAdmin does no account management on its own (other than
137 allowing one to manipulate the MySQL user account information); all users
138 must be valid MySQL users.</p>
140 <p class="footnote" id="footnote_1">
141 <sup>1)</sup> phpMyAdmin can compress (Zip, GZip -RFC 1952- or Bzip2 formats)
142 dumps and <abbr title="comma seperated values">CSV</abbr> exports if you use
143 PHP with Zlib support (<tt>--with-zlib</tt>) and/or Bzip2 support
144 (<tt>--with-bz2</tt>). Proper support may also need changes in
145 <tt>php.ini</tt>.</p>

155 </ol>
157 <p class="important">
158 phpMyAdmin does not apply any special security methods to the MySQL database
159 server. It is still the system administrator's job to grant permissions on
160 the MySQL databases properly. phpMyAdmin's &quot;Privileges&quot; page can
161 be used for this.
162 </p>
164 <p class="important">
165 Warning for <acronym title="Apple Macintosh">Mac</acronym> users:<br />
166 if you are on a <acronym title="Apple Macintosh">Mac</acronym>
167 <abbr title="operating system">OS</abbr> version before
168 <abbr title="operating system">OS</abbr> X, StuffIt unstuffs with
169 <acronym title="Apple Macintosh">Mac</acronym> formats.<br />
170 So you'll have to resave as in BBEdit to Unix style ALL phpMyAdmin scripts
171 before uploading them to your server, as PHP seems not to like
172 <acronym title="Apple Macintosh">Mac</acronym>-style end of lines character
173 (&quot;<tt>\r</tt>&quot;).</p>
175 <h3 id="quick_install">Quick Install</h3>
176 <ol><li>Choose an appropriate distribution kit from the phpmyadmin.net
177 Downloads page. Some kits contain only the English messages,
178 others contain all languages in UTF-8 format (this should be fine
179 in most situations), others contain all
180 languages and all character sets. We'll assume you chose a kit whose
181 name looks like <tt>phpMyAdmin-x.x.x-all-languages.tar.gz</tt>.
182 </li>
183 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
184 <tt>tar -xzvf phpMyAdmin_x.x.x-all-languages.tar.gz</tt> in your webserver's
185 document root. If you don't have direct access to your document root,
186 put the files in a directory on your local machine, and, after step 4,
187 transfer the directory on your web server using, for example, ftp.</li>
188 <li>Ensure that all the scripts have the appropriate owner (if PHP is
189 running in safe mode, having some scripts with an owner different
190 from the owner of other scripts will be a
191 problem). See <a href="#faq4_2">
192 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.2</a> and
193 <a href="#faq1_26"><abbr title="Frequently Asked Questions">FAQ</abbr>
194 1.26</a> for suggestions.</li>
195 <li>Now you must configure your installation. There are two methods that
196 can be used. Traditionally, users have hand-edited a copy of
197 <tt>config.inc.php</tt>, but now a wizard-style setup script is
198 provided for those who prefer a graphical installation. Creating a
199 <tt>config.inc.php</tt> file is
200 still a quick way to get started and needed for some advanced features.
201 <ul><li>To manually create the file, simply use your text editor to
202 create the file <tt>config.inc.php</tt> (you can copy
203 <tt>config.sample.inc.php</tt> to get minimal configuration
204 file) in the main (top-level) phpMyAdmin directory (the one
205 that contains <tt>index.php</tt>). phpMyAdmin first loads
206 <tt>libraries/config.default.php</tt> and then overrides those
207 values with anything found in <tt>config.inc.php</tt>. If the
208 default value is okay for a particular setting, there is no
209 need to include it in <tt>config.inc.php</tt>. You'll need a
210 few directives to get going, a simple configuration may look
211 like this:
212 <pre>
213 &lt;?php
214 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
216 $i=0;
217 $i++;
218 $cfg['Servers'][$i]['auth_type'] = 'cookie';
219 ?&gt;
220 </pre>
221 Or, if you prefer to not be prompted every time you log in:
222 <pre>
223 &lt;?php
225 $i=0;
226 $i++;
227 $cfg['Servers'][$i]['user'] = 'root';
228 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
229 ?&gt;
230 </pre>
231 For a full explanation of possible configuration values, see the
232 <a href="#config">Configuration Section</a> of this document.</li>
233 <li id="setup_script">Instead of manually editing
234 <tt>config.inc.php</tt>, you can use the
235 <a href="scripts/setup.php">Setup Script</a>. First you must
236 manually create a folder <tt>config</tt> in the phpMyAdmin
237 directory. This is a security measure. On a Linux/Unix system you
238 can use the following commands:
239 <pre>
240 cd phpMyAdmin
241 mkdir config # create directory for saving
242 chmod o+rw config # give it world writable permissions
243 </pre>
244 And to edit an existing configuration, copy it over first:
245 <pre>
246 cp config.inc.php config/ # copy current configuration for editing
247 chmod o+w config/config.inc.php # give it world writable permissions
248 </pre>
249 On other platforms, simply create the folder and ensure that your
250 web server has read and write access to it. <a href="#faq1_26">FAQ
251 1.26</a> can help with this.<br /><br />
253 Next, open <tt><a href="scripts/setup.php">scripts/setup.php</a>
254 </tt>in your browser. Note that <strong>changes are not saved to
255 disk until explicitly choose <tt>Save</tt></strong> from the
256 <i>Configuration</i> area of the screen. Normally the script saves
257 the new config.inc.php to the <tt>config/</tt> directory, but if
258 the webserver does not have the proper permissions you may see the
259 error "Cannot load or save configuration." Ensure that the <tt>
260 config/</tt> directory exists and has the proper permissions -
261 or use the <tt>Download</tt> link to save the config file locally
262 and upload (via FTP or some similar means) to the proper location.<br /><br />
264 Once the file has been saved, it must be moved out of the <tt>
265 config/</tt> directory and the permissions must be reset, again
266 as a security measure:
267 <pre>
268 mv config/config.inc.php . # move file to current directory
269 chmod o-rw config.inc.php # remove world read and write permissions
270 rm -rf config # remove not needed directory
271 </pre>
272 Now the file is ready to be used. You can choose to review or edit
273 the file with your favorite editor, if you prefer to set some
274 advanced options which the setup script does not provide.</li></ul></li>
275 <li>If you are using the
276 <tt>auth_type</tt> &quot;config&quot;, it is suggested that you
277 protect the phpMyAdmin installation directory because using
278 config does not require a user to
279 enter a password to access the phpMyAdmin installation. Use of an alternate
280 authentication method is recommended, for example with
281 HTTP&#8211;AUTH in a <a href="#glossary"><i>.htaccess</i></a> file or switch to using
282 <tt>auth_type</tt> cookie or http. See the
283 <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
284 <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
285 information, especially <a href="#faq4_4">
286 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
287 <li>Open the <a href="index.php">main phpMyAdmin directory</a>
288 in your browser. phpMyAdmin should now display a welcome screen
289 and your databases, or a login dialog if using
290 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
291 authentication mode.</li>
292 <li>You should deny access to the <tt>./libraries</tt> subfolder in your
293 webserver configuration. For Apache you can use supplied .htaccess file
294 in that folder, for other webservers, you should configure this yourself.
295 Such configuration prevents from possible path exposure and cross side
296 scripting vulnerabilities that might happen to be found in that code.</li>
297 </ol>
299 <h3 id="linked-tables">Linked-tables infrastructure</h3>
301 <p> For a whole set of new features (bookmarks, comments,
302 <abbr title="structured query language">SQL</abbr>-history,
303 <abbr title="Portable Document Format">PDF</abbr>-generation, field contents
304 transformation, etc.) you need to create a set of special tables. Those
305 tables can be located in your own database, or in a central database for a
306 multi-user installation (this database would then be accessed by the
307 controluser, so no other user should have rights to it).</p>
309 <p> Please look at your <tt>./scripts/</tt> directory, where you should find a
310 file called <i>create_tables.sql</i>. (If you are using a Windows server, pay
311 special attention to <a href="#faq1_23">
312 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>
314 <p> If your MySQL server's version is 4.1.2 or later, please use
315 <i>./scripts/create_tables_mysql_4_1_2+.sql</i> instead, for a new
316 installation.</p>
318 <p> If you already had this infrastructure and upgraded to MySQL 4.1.2
319 or later, please use <i>./scripts/upgrade_tables_mysql_4_1_2+.sql</i>.</p>
321 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
322 that you may need special (administrator) privileges to create the database
323 and tables, and that the script may need some tuning, depending on the
324 database name.</p>
326 <p> After having imported the <i>./scripts/create_tables.sql</i> file, you
327 should specify the table names in your <i>./config.inc.php</i> file. The
328 directives used for that can be found in the <a href="#config">Configuration
329 section</a>. You will also need to have a controluser with the proper rights
330 to those tables (see section <a href="#authentication_modes">Using
331 authentication modes</a> below).</p>
333 <h3 id="upgrading">Upgrading from an older version</h3>
335 <p> Simply copy <i>./config.inc.php</i> from your previous installation into the newly
336 unpacked one. Configuration files from very old versions (2.3.0 or before) may
337 require some tweaking as some options have been changed or removed.
338 For compatibility with PHP 6, remove a <tt>set_magic_quotes_runtime(0);</tt>
339 statement that you might find near the end of your configuration file.</p>
341 <p> You should <strong>not</strong> copy <tt>libraries/config.default.php</tt>
342 over <tt>config.inc.php</tt> because the default configuration file
343 is version-specific.</p>
345 <p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
346 version 4.1.2 or newer and if you use the pmadb/linked table infrastructure,
347 you should run the SQL script found in
348 <tt>scripts/upgrade_tables_mysql_4_1_2+.sql</tt>.</p>
350 <h3 id="authentication_modes">Using authentication modes</h3>
352 <ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
353 authentication modes are recommended in a <b>multi-user environment</b>
354 where you want to give users access to their own database and don't want
355 them to play around with others.<br />
356 Nevertheless be aware that MS Internet Explorer seems to be really buggy
357 about cookies, at least till version 6, and PHP 4.1.1 is also a bit buggy
358 in this area!<br />
359 Even in a <b>single-user environment</b>, you might prefer to use
360 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
361 that your user/password pair are not in clear in the configuration file.
362 </li>
364 <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
365 authentication modes are more secure: the MySQL login information does
366 not need to be set in the phpMyAdmin configuration file (except possibly
367 for the <a href="#controluser">controluser</a>).<br />
368 However, keep in mind that the password travels in plain text, unless
369 you are using the HTTPS protocol.<br />
370 In cookie mode, the password is stored, encrypted with the blowfish
371 algorithm, in a temporary cookie.</li>
373 <li>Note: starting with phpMyAdmin 2.6.1, this section is only applicable if
374 your MySQL server is previous to 4.1.2, or is running with
375 <tt>--skip-show-database</tt>.<br /><br />
377 For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
378 modes, phpMyAdmin needs a controluser that has <b>only</b> the
379 <tt>SELECT</tt> privilege on the <i>`mysql`.`user` (all columns except
380 `Password`)</i>, <i>`mysql`.`db` (all columns)</i>, <i>`mysql`.`host`
381 (all columns)</i> and <i>`mysql`.`tables_priv` (all columns except
382 `Grantor` and `Timestamp`)</i> tables.<br /> You must specify the details
383 for the <a href="#controluser">controluser</a> in the <tt>config.inc.php</tt>
384 file under the
385 <tt><a href="#cfg_Servers_controluser" class="configrule">
386 $cfg['Servers'][$i]['controluser']</a></tt> and
387 <tt><a href="#cfg_Servers_controlpass" class="configrule">
388 $cfg['Servers'][$i]['controlpass']</a></tt> settings.<br />
389 The following example assumes you want to use <tt>pma</tt> as the
390 controluser and <tt>pmapass</tt> as the controlpass, but <b>this is
391 only an example: use something else in your file!</b> Input these
392 statements from the phpMyAdmin SQL Query window or mysql command&#8211;line
393 client.<br />
394 Of course you have to replace <tt>localhost</tt> with the webserver's host
395 if it's not the same as the MySQL server's one.
397 <pre>
398 GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
399 GRANT SELECT (
400 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
401 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
402 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
403 Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
404 Execute_priv, Repl_slave_priv, Repl_client_priv
405 ) ON mysql.user TO 'pma'@'localhost';
406 GRANT SELECT ON mysql.db TO 'pma'@'localhost';
407 GRANT SELECT ON mysql.host TO 'pma'@'localhost';
408 GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
409 ON mysql.tables_priv TO 'pma'@'localhost';</pre>
411 If you are using an old MySQL version (below 4.0.2), please replace
412 the first GRANT SELECT query by this one:
414 <pre>
415 GRANT SELECT (
416 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
417 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
418 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv
419 ) ON mysql.user TO 'pma'@'localhost';</pre>
421 ... and if you want to use the many new relation and bookmark features:
423 <pre>
424 GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
425 </pre>
427 (this of course requires that your <a href="#linked-tables">linked-tables
428 infrastructure</a> be set up).<br />
429 Of course, the above queries only work if your MySQL version supports
430 the GRANT command. This is the case since 3.22.11.</li>
432 <li>Then each of the <i>true</i> users should be granted a set of privileges
433 on a set of particular databases. Normally you shouldn't give global
434 privileges to an ordinary user, unless you understand the impact of those
435 privileges (for example, you are creating a superuser).<br />
436 For example, to grant the user <i>real_user</i> with all privileges on
437 the database <i>user_base</i>:<br />
439 <pre>
440 GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';
441 </pre>
443 What the user may now do is controlled entirely by the MySQL user
444 management system.<br />
445 With <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
446 authentication mode, you don't need to fill the user/password fields
447 inside the <a href="#cfg_Servers" class="configrule">$cfg['Servers']</a>
448 array.</li>
449 </ul>
451 <h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>

466 using the <i>.htaccess</i> mechanism along with
467 '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication
468 mode.</li>
469 </ul>
471 <h4>'cookie' authentication mode</h4>
473 <ul><li>You can use this method as a replacement for the
474 <abbr title="HyperText Transfer Protocol">HTTP</abbr> authentication
475 (for example, if you're running
476 <abbr title="Internet Information Services">IIS</abbr>).</li>
477 <li>Obviously, the user must enable cookies in the browser, but this is
478 now a requirement for all authentication modes.</li>
479 <li>With this mode, the user can truly log out of phpMyAdmin and log in back
480 with the same username.</li>
481 <li>If you want to log in to arbitrary server see
482 <a href="#AllowArbitraryServer" class="configrule">
483 $cfg['AllowArbitraryServer']</a> directive.</li>
484 <li>As mentioned in the <a href="#require">requirements</a> section, having
485 the <tt>mcrypt</tt> extension will speed up access considerably, but is
486 not required.</li>
487 </ul>
489 <h4>'signon' authentication mode</h4>
491 <ul><li>This mode is a convenient way of using credentials from another
492 application to authenticate to phpMyAdmin.</li>
493 <li>The other application has to store login information into
494 session data.</li>
495 <li>More details in the <a href="#cfg_Servers_auth_type">auth_type</a>
496 section.</li>
497 </ul>
498 <h4>'config' authentication mode</h4>
500 <ul><li>This mode is the less secure one because it requires you to fill the
501 <a href="#servers_user" class="configrule">
502 $cfg['Servers'][$i]['user']</a> and
503 <a href="#servers_user" class="configrule">
504 $cfg['Servers'][$i]['password']</a> fields (and as a result, anyone who
505 can read your config.inc.php can discover your username and password).
506 <br />
507 But you don't need to setup a &quot;controluser&quot; here: using the
508 <a href="#servers_only_db" class="configrule">
509 $cfg['Servers'][$i]['only_db']</a> might be enough.</li>
510 <li>In the <a href="#faqmultiuser">
511 <abbr title="Internet service provider">ISP</abbr>
512 <abbr title="Frequently Asked Questions">FAQ</abbr></a> section, there
513 is an entry explaining how to protect your configuration file.</li>
514 <li>For additional security in this mode, you may wish to consider the Host
515 authentication
516 <a href="#servers_allowdeny_order" class="configrule">
517 $cfg['Servers'][$i]['AllowDeny']['order']</a> and
518 <a href="#servers_allowdeny_rules" class="configrule">
519 $cfg['Servers'][$i]['AllowDeny']['rules']</a> configuration
520 directives.</li>
521 <li>Unlike cookie and http, does not require a user to log in when first
522 loading the phpMyAdmin site. This is by design but could allow any
523 user to access your installation. Use of some restriction method is
524 suggested, perhaps a <a href="#glossary">.htaccess</a> file with the
525 HTTP-AUTH directive or disallowing incoming HTTP requests at
526 one&#8217;s router or firewall will suffice (both of which
527 are beyond the scope of this manual but easily searchable with Google).</li>

558 Don&#8217;t forget the trailing slash at the end.<br /><br />
560 Starting with version 2.3.0, it is advisable to try leaving this

564 A good test is to browse a table, edit a row and save it. There should
565 be an error message if phpMyAdmin is having trouble auto&#8211;detecting
566 the correct value. If you get an error that this must be set or if

700 <li>'cookie' authentication mode
701 (<tt>$auth_type&nbsp;=&nbsp;'cookie'</tt>) as introduced in

752 database(s) name(s) may contain MySQL wildcards characters

754 of these characters, escape them (I.E. use <tt>'my\_db'</tt> and not
755 <tt>'my_db'</tt>).<br />
756 This setting is an efficient way to lower the server load since the
757 latter does not need to send MySQL requests to build the available
758 database list. But <span class="important">it does not replace the

766 <br /><br />
768 As of phpMyAdmin 2.5.5 the order inside the array is used for sorting the
769 databases in the left frame, so that you can individually arrange your databases.<br />
770 If you want to have certain databases at the top, but don't care about the others, you do not
771 need to specify all other databases. Use:
772 <tt>$cfg['Servers'][$i]['only_db'] = array('db3', 'db4', '*');</tt>

778 <dd>Regular expression for hiding some databases. This only hides them
779 from listing, but a user is still able to access them (using, for example,
780 the SQL query area). To limit access, use the MySQL privilege system.
781 <br /><br />
782 For example, to hide all databases starting with the letter &#34;a&#34;, use<br />
783 <pre>$cfg['Servers'][$i]['hide_db'] = '^a';</pre>
784 and to hide both &#34;db1&#34; and &#34;db2&#34; use <br />

910 infrastructure</li>
911 <li>put the correct table names in

922 <dd><!-- This part requires a content update! -->
923 Since release 2.3.0 you can store comments to describe each column for
924 each table. These will then be shown on the &quot;printview&quot;.
925 <br /><br />
927 Starting with release 2.5.0, comments are consequently used on the table
928 property pages and table browse view, showing up as tool-tips above the
929 column name (properties page) or embedded within the header of table in
930 browse view. They can also be shown in a table dump. Please see the
931 relevant configuration directives later on.<br /><br />
933 Also new in release 2.5.0 is a MIME-transformation system which is also
934 based on the following table structure. See <a href="#transformations">
935 Transformations</a> for further information. To use the
936 MIME-transformation system, your column_info table has to have the three
937 new fields 'mimetype', 'transformation', 'transformation_options'.
938 <br /><br />
940 To allow the usage of this functionality:
941 <ul><li>set up <a href="#pmadb">pmadb</a> and the linked-tables
942 infrastructure</li>
943 <li>put the table name in
944 <tt>$cfg['Servers'][$i]['column_info']</tt></li>
945 <li>to update your PRE-2.5.0 Column_comments Table use this:
947 <pre>
948 ALTER TABLE `pma_column_comments`
949 ADD `mimetype` VARCHAR( 255 ) NOT NULL,
950 ADD `transformation` VARCHAR( 255 ) NOT NULL,
951 ADD `transformation_options` VARCHAR( 255 ) NOT NULL;
952 </pre>
954 and remember that the Variable in <i>config.inc.php</i> has been

966 all queries you entered manually into the phpMyAdmin interface. If you
967 don't want to use a table-based history, you can use the JavaScript-based

1025 authentication is disabled.<br /><br />
1027 If your rule order is set to <tt>'deny,allow'</tt> then the system applies
1028 all deny rules followed by allow rules. Access is allowed by default. Any
1029 client which does not match a Deny command or does match an Allow command
1030 will be allowed access to the server. <br /><br />
1032 If your rule order is set to <tt>'allow,deny'</tt> then the system
1033 applies all allow rules followed by deny rules. Access is denied by
1034 default. Any client which does not match an Allow directive or does
1035 match a Deny directive will be denied access to the server.<br /><br />
1037 If your rule order is set to 'explicit', the authentication is
1038 performed in a similar fashion to rule order 'deny,allow', with the
1039 added restriction that your host/username combination <b>must</b> be
1040 listed in the <i>allow</i> rules, and not listed in the <i>deny</i>
1041 rules. This is the <b>most</b> secure means of using Allow/Deny rules,

1755 1.11</a>.
1756 <br /><br />
1758 If the directory where phpMyAdmin is installed is subject to an
1759 <tt>open_basedir</tt> restriction, you need to create a
1760 temporary directory in some directory accessible by the web
1761 server. However for security reasons, this directory should be outside
1762 the tree published by webserver. If you cannot avoid having this
1763 directory published by webserver, place at least an empty
1764 <tt>index.html</tt> file there, so that directory listing is not
1765 possible.
1766 <br /><br />
1768 This directory should have as strict permissions as possible as the only
1769 user required to access this directory is the one who runs the
1770 webserver. If you have root privileges, simply make this user owner of
1771 this directory and make it accessible only by it:
1772 <br /><br />
1774 <pre>
1775 chown www-data:www-data tmp
1776 chmod 700 tmp
1777 </pre>
1779 If you cannot change owner of the directory, you can achieve a similar
1780 setup using <abbr title="Access Control List">ACL</abbr>:
1782 <pre>
1783 chmod 700 tmp
1784 setfacl -m "g:www-data:rwx" tmp
1785 setfacl -d -m "g:www-data:rwx" tmp
1786 </pre>
1788 If neither of above works for you, you can still make the directory
1789 <code>chmod 777</code>, but it might impose risk of other users on
1790 system reading and writing data in this directory.

1820 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
1821 or icon is always displayed on the left panel. If JavaScript is enabled in
1822 your browser, a click on this opens a distinct query window, which is
1823 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
1824 changes to display a query box.<br /><br />
1826 The size of this query window can be customized with
1827 <tt>$cfg['QueryWindowWidth']</tt> and <tt>$cfg['QueryWindowWidth']</tt>
1828 - both integers for the size in pixels. Note that normally, those
1829 parameters will be modified in <tt>layout.inc.php</tt> for the
1830 theme you are using.<br /><br />
1832 If <tt>$cfg['EditInWindow']</tt> is set to true, a click on [Edit]
1833 from the results page (in the &quot;Showing Rows&quot; section)
1834 opens the query window and puts the current query
1835 inside it. If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
1836 query in the right panel's query box.
1837 <br /><br />
1838 The usage of the JavaScript query window is recommended if you have a
1839 JavaScript enabled browser. Basic functions are used to exchange quite
1840 a few variables, so most 4th generation browsers should be capable to
1841 use that feature. It currently is only tested with Internet Explorer 6
1842 and Mozilla 1.x.
1843 <br /><br />
1844 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt>, all your Queries are logged
1845 to a table, which has to be created by you (see <a
1846 href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>). If set to FALSE,
1847 all your queries will be appended to the form, but only as long as
1848 your window is opened they remain saved.
1849 <br /><br />
1850 When using the JavaScript based query window, it will always get
1851 updated when you click on a new table/db to browse and will focus if
1852 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
1853 the query window by checking the box "Do not overwrite this query from
1854 outside the window" below the query textarea. Then you can browse
1855 tables/databases in the background without losing the contents of the
1856 textarea, so this is especially useful when composing a query with
1857 tables you first have to look in. The checkbox will get automatically
1858 checked whenever you change the contents of the textarea. Please
1859 uncheck the button whenever you definitely want the query window to
1860 get updated even though you have made alterations.
1861 <br /><br />
1862 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt> you can specify the amount of
1863 saved history items using <tt>$cfg['QueryHistoryMax']</tt>.
1864 <br /><br />
1865 The query window also has a custom tabbed look to group the features.
1866 Using the variable <tt>$cfg['QueryWindowDefTab']</tt> you can specify the
1867 default tab to be used when opening the query window. It can be set to
1868 either 'sql', 'files', 'history' or 'full'.</dd>

1893 where you edit x/y coordinates of those elements you can activate a
1894 scratchboard where all your elements are placed. By clicking on an
1895 element, you can move them around in the pre-defined area and the x/y
1896 coordinates will get updated dynamically. Likewise, when entering a
1897 new position directly into the input field, the new position in the
1898 scratchboard changes after your cursor leaves the input field.<br />
1899 You have to click on the 'OK'-button below the tables to save the new
1900 positions. If you want to place a new element, first add it to the
1901 table of elements and then you can drag the new element around.<br />
1902 By changing the paper size and the orientation you can change the size
1903 of the scratchboard as well. You can do so by just changing the
1904 dropdown field below, and the scratchboard will resize automatically,
1905 without interfering with the current placement of the elements.<br />
1906 If ever an element gets out of range you can either enlarge the paper
1907 size or click on the 'reset' button to place all elements below each
1908 other.<br />

2123 <ol><li><a href="#transformationsintro">Introduction</a></li>
2124 <li><a href="#transformationshowto">Usage</a></li>
2125 <li><a href="#transformationsfiles">File structure</a></li>
2126 </ol>
2128 <h3 id="transformationsintro">1. Introduction</h3>
2130 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2131 and the proper directives. Please see the <a href="#config">Configuration
2132 section</a> on how to do so.</p>
2134 <p> You can apply different transformations to the contents of each field. The
2135 transformation will take the content of each field and transform it with
2136 certain rules defined in the selected transformation.</p>
2138 <p> Say you have a field 'filename' which contains a filename. Normally you would
2139 see in phpMyAdmin only this filename. Using transformations you can transform
2140 that filename into a HTML link, so you can click inside of the phpMyAdmin
2141 structure on the field's link and will see the file displayed in a new browser
2142 window. Using transformation options you can also specify strings to
2143 append/prepend to a string or the format you want the output stored in.</p>
2145 <p> For a general overview of all available transformations and their options,
2146 you can consult your
2147 <i>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</i>
2148 installation.</p>
2150 <p> For a tutorial on how to effectively use transformations, see our
2151 <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
2152 the official phpMyAdmin homepage.</p>
2154 <h3 id="transformationshowto">2. Usage</h3>
2156 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2157 clicking on the 'Structure' link for a table). There click on
2158 &quot;Change&quot; (or change icon) and there you will see three new fields at
2159 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2160 'Transformation options'.</p>
2162 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2163 that corresponds to the column's contents. Please note that
2164 transformations are inactive as long as no MIME-type is selected.</li>
2166 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2167 hopefully growing amount of pre-defined transformations. See below for information on
2168 how to build your own transformation.<br />
2170 There are global transformations and mimetype-bound transformations. Global transformations
2171 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2172 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2173 transformations which operate on the main mimetype (like 'image'), which will most likely
2174 take the subtype into regard, and those who only operate on a
2175 specific subtype (like 'image/jpeg').<br />
2177 You can use transformations on mimetypes for which the function was not defined for. There
2178 is no security check for you selected the right transformation, so take care of what the
2179 output will be like.</li>
2181 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2182 transform-function specific options here. Usually the transforms can operate with default
2183 options, but it is generally a good idea to look up the overview to see which options are
2184 necessary.<br />
2186 Much like the ENUM/SET-Fields, you have to split up several options using the format
2187 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2188 parsed as an array, leaving the first value the first element in the array, and so
2189 forth.<br />
2191 If you want to specify a MIME character set you can define it in the transformation_options.
2192 You have to put that outside of the pre-defined options of the specific mime-transform,
2193 as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
2194 for which you can specify 2 options and you want to append a character set, enter "'first
2195 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2196 the parameters: "'','','charset=us-ascii'".</li>
2197 </ul>
2199 <h3 id="transformationsfiles">3. File structure</h3>
2201 <p> All mimetypes and their transformations are defined through single files in
2202 the directory 'libraries/transformations/'.</p>
2204 <p> They are stored in files to ease up customization and easy adding of new
2205 transformations.</p>
2207 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2208 always work. It makes no sense to apply a transformation to a mimetype, the
2209 transform-function doesn't know to handle.</p>
2211 <p> One can, however, use empty mime-types and global transformations which should work
2212 for many mimetypes. You can also use transforms on a different mimetype they where built
2213 for, but pay attention to option usage as well as what the transformation does to your
2214 field.</p>
2216 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2217 any other transform function and provides some basic functions.</p>
2219 <p> There are 5 possible file names:</p>
2221 <ol><li>A mimetype+subtype transform:<br /><br />
2223 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2225 Please not that mimetype and subtype are separated via '_', which shall
2226 not be contained in their names. The transform function/filename may
2227 contain only characters which cause no problems in the file system as
2228 well as the PHP function naming convention.<br /><br />
2230 The transform function will the be called
2231 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2233 <b>Example:</b><br /><br />
2235 <tt>text_html__formatted.inc.php</tt><br />
2236 <tt>PMA_transform_text_html__formatted()</tt></li>
2238 <li>A mimetype (w/o subtype) transform:<br /><br />
2240 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2242 Please note that there are no single '_' characters.
2243 The transform function/filename may contain only characters which cause
2244 no problems in the file system as well as the PHP function naming
2245 convention.<br /><br />
2247 The transform function will the be called
2248 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2250 <b>Example:</b><br /><br />
2252 <tt>text__formatted.inc.php</tt><br />
2253 <tt>PMA_transform_text__formatted()</tt></li>
2255 <li>A mimetype+subtype without specific transform function<br /><br />
2257 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2259 Please note that there are no '__' characters in the filename. Do not
2260 use special characters in the filename causing problems with the file
2261 system.<br /><br />
2263 No transformation function is defined in the file itself.<br /><br />
2265 <b>Example:</b><br /><br />
2267 <tt>text_plain.inc.php</tt><br />
2268 (No function)</li>
2270 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2272 <tt>[mimetype].inc.php</tt><br /><br />
2274 Please note that there are no '_' characters in the filename. Do not use
2275 special characters in the filename causing problems with the file system.
2276 <br /><br />
2278 No transformation function is defined in the file itself.<br /><br />
2280 <b>Example:</b><br /><br />
2282 <tt>text.inc.php</tt><br />
2283 (No function)</li>
2285 <li>A global transform function with no specific mimetype<br /><br />
2287 <tt>global__[transform].inc.php</tt><br /><br />
2289 The transform function will the be called
2290 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2292 <b>Example:</b><br /><br />
2294 <tt>global__formatted</tt><br />
2295 <tt>PMA_transform_global__formatted()</tt></li>
2296 </ol>
2298 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2299 transform function.</p>
2301 <p> All filenames containing no '__' in themselves are not shown as valid transform
2302 functions in the dropdown.</p>
2304 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2305 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2306 without a transform function. Also note the introduction of a function description in
2307 the language files. For each function a $strTransformation_[filename without .inc.php]
2308 has to exist.</p>
2310 <p> You can use the template generator to generate new functions and entries in the
2311 language file.</p>
2313 <p> To create a new transform function please see
2314 <tt>libraries/transformations/template_generator.sh</tt>.
2315 To create a new, empty mimetype please see
2316 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2318 <p> A transform function always gets passed three variables:</p>
2320 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2321 you want to transform.</li>
2322 <li><b>$options</b> - Contains any user-passed options to a transform function
2323 as an array.</li>
2324 <li><b>$meta</b> - Contains an object with field information to your column.
2325 The data is drawn from the output of the
2326 <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
2327 function. This means, all object properties described on the
2328 <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
2329 available in this variable and can be used to transform a field accordingly
2330 to unsigned/zerofill/not_null/... properties.<br />
2331 The $meta-&gt;mimetype variable contains the original MIME-type of the
2332 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2333 </ol>

2447 <li>give ownership to the Apache server's user.group:

2460 and you updated your PHP RPM to php-4.0.4pl1-3.i386.rpm, didn't you?<br />
2461 So the problem is that this package has a serious bug that was corrected

2463 <a href="http://www.php.net/bugs.php?id=8966">PHP's bug tracking system</a>
2464 for more details). The problem is that the bugged package is still

2527 <a href="#faq1_16">1.16 I cannot upload big dump files (memory,
2528 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or timeout problems).</a>
2529 </h4>
2531 <p> Starting with version 2.7.0, the import engine has been re&#8211;written and these
2532 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2533 to take advantage of the new import features.</p>
2535 <p> The first things to check (or ask your host provider to check) are the
2536 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2537 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2538 All of these three settings limit the maximum size of data that can be
2539 submitted and handled by PHP. One user also said that post_max_size
2540 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2542 There exist several workarounds if your upload is too big or your
2543 hosting provider is unwilling to change the settings:</p>
2545 <ul><li>Look at the <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>
2546 feature. This allows one to
2547 upload a file to the server via scp, ftp, or your favorite file transfer
2548 method. PhpMyAdmin is then able to import the files from the temporary
2549 directory. More information is available in the <a href="#config">Configuration
2550 section</a> of this document.</li>
2551 <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php">
2552 BigDump</a>) to split the files before uploading. We cannot support this
2553 or any third party applications, but are aware of users having success
2554 with it.</li>
2555 <li>If you have shell (command line) access, use MySQL to import the files
2556 directly. You can do this by issuing the &quot;source&quot; command from
2557 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2558 </ul>
2560 <h4 id="faq1_17">
2561 <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
2562 support?</a></h4>
2564 <p> All MySQL versions from 3.23.32 till 5.0 (except for 4.1.0 and 4.1.1) are
2565 fully supported. Please note that the older your MySQL version is, the more
2566 limitations you will have to face.<br />
2567 phpMyAdmin may connect to your MySQL server using php's classic
2568 <a href="http://php.net/mysql">MySQL extension</a> as well as the
2569 <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
2570 is available in php 5.0.<br />
2571 Either way, the developers of both extensions recommend to use the classic
2572 extension for MySQL 4.0 and below and MySQLi for MySQL 4.1 and newer.<br />
2573 When compiling php, we strongly recommend that you manually link the MySQL
2574 extension of your choice to a MySQL client library of at least the same
2575 minor version since the one that is bundled with some php distributions is
2576 rather old and might cause problems <a href="#faq1_17a">
2577 (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.
2578 If your webserver is running on a windows system, you might want to try
2579 MySQL's
2580 <a href="http://dev.mysql.com/downloads/connector/php/">Connector/PHP</a>
2581 instead of the MySQL / MySQLi extensions that are bundled with the official
2582 php Win32 builds.

2584 MySQL&nbsp;5.1 is not yet supported.</p>
2586 <h5 id="faq1_17a">

2588 message, &quot;Client does not support authentication protocol requested

2591 <p> You tried to access MySQL with an old MySQL client library. The version of
2592 your MySQL client library can be checked in your phpinfo() output.
2593 In general, it should have at least the same minor version as your server
2594 - as mentioned in <a href="#faq1_17">
2595 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />
2597 This problem is generally caused by using MySQL version 4.1 or newer. MySQL
2598 changed the authentication hash and your PHP is trying to use the old method.
2599 The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
2600 with the proper client library to match your MySQL installation. Your
2601 chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.

2630 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2631 &quot;MySQL extension&quot;. This extension may be part of the PHP
2632 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2633 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2634 to load the extension but failed.<br /><br />

2886 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
2888 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
2889 In your <i>php.ini</i> you will find a line</p>
2891 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
2893 <p> change it to</p>
2895 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
2897 <p> Then restart apache and it will work.</p>
2899 <p> Here is a fix suggested by Brad Ummer:</p>
2901 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
2902 To do this, telnet to your server and go to the MySQL bin directory. In
2903 this directory there should be a file named <i>mysqladmin</i>. Type
2904 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
2905 info about your MySQL server, including the socket
2906 (<i>/tmp/mysql.sock</i>, for example).</li>
2907 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
2908 phpMyAdmin, you need to complete the socket information in the
2909 <i>config.inc.php</i>.<br />
2910 For example:
2911 <a href="#cfg_Servers_socket" class="configrule">
2912 $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
2913 <br /><br />
2915 Please also make sure that the permissions of this file allow to be readable
2916 by your webserver (i.e. '0755').</li>
2917 </ul>
2919 <p> Have also a look at the
2920 <a href="http://www.mysql.com/doc/C/a/Can_not_connect_to_server.html">
2921 corresponding section of the MySQL documentation</a>.</p>

2948 <p> When you are using a port on your localhost, which you redirect via
2949 port-forwarding to another host, MySQL is not resolving the localhost
2950 as expected.<br />
2951 Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
2952 MySQL (the commandline tool 'mysql' as well) always tries to use the socket
2953 connection for speeding up things. And that doesn't work in this configuration
2954 with port forwarding.<br />

2962 <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
2963 <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
2964 <br />
2965 Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
2966 should not delete the directory &quot;original&quot; or its underlying
2967 structure, because this is the system theme used by phpMyAdmin.
2968 &quot;original&quot; contains all images and styles, for backwards
2969 compatibility and for all themes that would not include images or css-files.
2970 <br /><br />
2972 If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
2973 is enabled, you can select your favorite theme on the main page. Your
2974 selected theme will be stored in a cookie.<br /><br /></p>
2976 <p> To create a theme:</p>
2978 <ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
2979 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
2980 (by default <tt>themes</tt>)</li>
2981 <li>copy the files and directories from &quot;original&quot; to
2982 &quot;your_theme_name&quot;</li>
2983 <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
2984 <li>put your new images in &quot;your_theme_name/img&quot;</li>
2985 <li>edit <tt>layout.inc.php</tt> in &quot;your_theme_name&quot;</li>
2986 <li>edit <tt>info.inc.php</tt> in &quot;your_theme_name&quot; to
2987 contain your chosen theme name, that will be visible in user interface</li>
2988 <li>make a new screenshot of your theme and save it under
2989 &quot;your_theme_name/screen.png&quot;</li>
2990 </ul>
2992 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
2993 theme verbose name, theme generation and theme version. These versions and
2994 generations are enumerated from 1 and do not have any direct dependence on
2995 phpMyAdmin version. Themes within same generation should be backwards
2996 compatible - theme with version 2 should work in phpMyAdmin requiring
2997 version 1. Themes with different generation are incompatible.</p>
2999 <p> If you do not want to use your own symbols and buttons, remove the
3000 directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
3001 use the default icons and buttons (from the system-theme &quot;original&quot;).

3141 MySQL server</a></h4>
3143 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3144 differences in how <abbr title="structured query language">SQL</abbr> is
3145 structured (see <a href="http://dev.mysql.com/doc/mysql/en/ANSI_mode.html">
3146 http://dev.mysql.com/doc/mysql/en/ANSI_mode.html</a>). Most important of all,
3147 the quote-character (") is interpreted as an identifier quote character and
3148 not as a string quote character, which makes many internal phpMyAdmin
3149 operations into invalid <abbr title="structured query language">SQL</abbr>
3150 statements. There is no workaround to this behaviour. News to this item will
3151 be posted in Bug report

3186 API does not accept this syntax for the USE command. Enclosing the

3205 Since version 2.0.3, you can setup a central copy of phpMyAdmin for all

3207 NetCologne GmbH.
3208 This requires a properly setup MySQL user management and phpMyAdmin

3214 <a href="#faq4_2">4.2 What's the preferred way of making phpMyAdmin secure against evil
3215 access.
3216 </a></h4>
3218 This depends on your system.<br />
3219 If you're running a server which cannot be accessed by other people, it's
3220 sufficient to use the directory protection bundled with your webserver
3221 (with Apache you can use <i>.htaccess</i> files, for example).<br />
3222 If other people have telnet access to your server, you should use
3223 phpMyAdmin's <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie authentication features.
3224 <br /><br />
3225 Suggestions:
3226 </p>
3227 <ul>
3228 <li>
3229 Your <i>config.inc.php</i> file should be <tt>chmod 660</tt>.
3230 </li>
3231 <li>
3232 All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy
3233 is a user whose password is only known to you, and apache is the
3234 group under which Apache runs.
3235 </li>
3236 <li>
3237 You should use PHP safe mode, to protect from other users that try
3238 to include your <i>config.inc.php</i> in their scripts.
3239 </li>
3240 </ul>

3243 <a href="#faq4_3">4.3 I get errors about not being able to include a file in
3244 <i>/lang</i> or in <i>/libraries</i>.
3245 </a></h4>
3247 Check <i>php.ini</i>, or ask your sysadmin to check it. The
3248 <tt>include_path</tt> must contain &quot;.&quot; somewhere in it, and
3249 <tt>open_basedir</tt>, if used, must contain &quot;.&quot; and

3260 <ul><li><a href="#cfg_Servers_controluser" class="configrule">$cfg['Servers'][$i]['controluser']</a>

3264 <li>The username/password you specify in the login dialog are invalid.</li>
3265 <li>You have already setup a security mechanism for the
3266 phpMyAdmin-directory, eg. a .htaccess file. This would interfere with

3271 <a href="#faq4_5">4.5 Is it possible to let users create their own databases?</a></h4>
3273 <p> Starting with 2.2.5, in the user management page, you can enter a wildcard
3274 database name for a user (for example &quot;joe%&quot;),
3275 and put the privileges you want. For example,
3276 adding <tt>SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER</tt>
3277 would let a user create/manage his/her database(s).</p>
3279 <h4 id="faq4_6">
3280 <a href="#faq4_6">4.6 How can I use the Host-based authentication additions?</a></h4>
3282 <p> If you have existing rules from an old .htaccess file, you can take them
3283 and add a username between the <tt>'deny'</tt>/<tt>'allow'</tt> and
3284 <tt>'from'</tt> strings. Using the username wildcard of <tt>'%'</tt> would
3285 be a major benefit here if your installation is suited to using it. Then

3641 <br /><br />
3642 Then you need to think about your schema layout. Which tables will go on
3643 which pages?
3644 </p>
3645 <ul>

3654 <li>Select the name of the new page (making sure the Edit radio button
3655 is selected) and click Go.</li>
3656 <li>Select a table from the list, enter its coordinates and click Save.<br />
3657 Coordinates are relative; your diagram will
3658 be automatically scaled to fit the page. When initially placing tables
3659 on the page, just pick any coordinates -- say, 50x50. After clicking
3660 Save, you can then use the <a href="#wysiwyg">graphical editor</a> to
3661 position the element correctly.</li>
3662 <li>When you'd like to look at your <abbr title="Portable Document Format">PDF</abbr>,
3663 first be sure to click the Save
3664 button beneath the list of tables and coordinates, to save any changes
3665 you made there. Then scroll all the way down, select the
3666 <abbr title="Portable Document Format">PDF</abbr> options
3667 you want, and click Go.</li>
3668 <li>Internet Explorer for Windows may suggest an incorrect filename when

3709 if it already exists during the import. It does NOT drop the table after
3710 your export, it only affects the import file.</li>
3711 <li>&quot;If Not Exists&quot; will only create the table if it doesn't exist.
3712 Otherwise, you may get an error if the table name exists but has a
3713 different structure.</li>
3714 <li>&quot;Add AUTO_INCREMENT value&quot; ensures that AUTO_INCREMENT value
3715 (if any) will be included in backup.</li>
3716 <li>&quot;Enclose table and field names with backquotes&quot; ensures that
3717 field and table names formed with special characters are protected.</li>

3741 <a href="#faq6_13">6.13 I would like to create a database with a dot

3744 <p> This is a bad idea, because in MySQL the syntax &quot;database.table&quot;

3746 will usually let you create a database with a dot, but then you cannot
3747 work with it, nor delete it.</p>
3749 <h4 id="faqsqlvalidator">
3750 <a href="#faqsqlvalidator">6.14 How do I set up the
3751 <abbr title="structured query language">SQL</abbr> Validator?</a></h4>
3753 <p> To use it, you need a very recent version of PHP, 4.3.0 recommended, with
3754 <abbr title="Extensible Markup Language">XML</abbr>,
3755 <abbr title="Perl Compatible Regular Expressions">PCRE</abbr> and
3756 <abbr title="PHP Extension and Application Repository">PEAR</abbr> support.
3757 On your system command line, run <tt>"pear install Net_Socket Net_URL
3758 HTTP_Request Mail_Mime Net_DIME SOAP"</tt> to get the necessary
3759 <abbr title="PHP Extension and Application Repository">PEAR</abbr> modules
3760 for usage.<br />
3761 On a more recent pear version, I had problems with the state of Net_DIME
3762 being beta, so this single command
3763 <tt>"pear -d preferred_state=beta install -a SOAP"</tt> installed all the
3764 needed modules.<br />
3765 If you use the Validator, you should be aware that any
3766 <abbr title="structured query language">SQL</abbr> statement you
3767 submit will be stored anonymously (database/table/column names,
3768 strings, numbers replaced with generic values). The Mimer
3769 <abbr title="structured query language">SQL</abbr>
3770 Validator itself, is &copy; 2001 Upright Database Technology.

3775 it, but MySQL says &quot;BLOB column '...' used in key specification without
3776 a key length&quot;.</a></h4>
3778 <p> The right way to do this, is to create the field without any indexes,
3779 then display the table structure and use the &quot;Create an index&quot;
3780 dialog. On this page, you will be able to choose your BLOB field, and
3781 set a size to the index, which is the condition to create an index on
3782 a BLOB field.</p>
3784 <h4 id="faq6_16">
3785 <a href="#faq6_16">6.16 How can I simply move in page with plenty
3786 editing fields?</a></h4>
3788 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
3789 with many editing fields (table structure changes, row editing, etc.)
3790 (must be enabled in configuration - see.
3791 <a href="#CtrlArrowsMoving" class="configrule">$cfg['CtrlArrowsMoving']</a>).
3792 You can also have a look at the directive
3793 <a href="#DefaultPropDisplay" class="configrule">$cfg['DefaultPropDisplay']</a>
3794 ('vertical') and see if this eases up editing for you.</p>

3797 <a href="#faq6_17">6.17 Transformations: I can't enter my own mimetype!
3798 WTF is this feature then useful for?</a></h4>
3800 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
3801 on them. Otherwise you could just put a comment on the field. Because entering
3802 your own mimetype will cause serious syntax checking issues and validation,
3803 this introduces a high-risk false-user-input situation. Instead you have to
3804 initialize mimetypes using functions or empty mimetype definitions.<br />
3805 Plus, you have a whole overview of available mimetypes. Who knows all those
3806 mimetypes by heart so he/she can enter it at will?</p>
3808 <h4 id="faqbookmark">
3809 <a href="#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
3810 can't I see any bookmarks below the query box? What is this variable for?
3811 </a></h4>
3813 <p> Any query you have executed can be stored as a bookmark on the page where the
3814 results are displayed. You will find a button labeled 'Bookmark this query'
3815 just at the end of the page.<br />
3816 As soon as you have stored a bookmark, it is related to the database you run
3817 the query on. You can now access a bookmark dropdown on each page, the query
3818 box appears on for that database.<br /><br />
3820 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
3821 Just use the string <b>/*[VARIABLE]*/</b> anywhere in your query. Everything
3822 which is put into the <i>value</i> input box on the query box page will
3823 replace the string &quot;/*[VARIABLE]*/&quot; in your stored query. Just be
3824 aware of that you HAVE to create a valid query, otherwise your query won't be
3825 even able to be stored in the database.<br />
3826 Also remember, that everything else inside the <b>/*[VARIABLE]*/</b> string
3827 for your query will remain the way it is, but will be stripped of the /**/
3828 chars. So you can use:<br /><br />
3830 <code>/*, [VARIABLE] AS myname */</code><br /><br />
3832 which will be expanded to<br /><br />
3834 <code>, VARIABLE as myname</code><br /><br />
3836 in your query, where VARIABLE is the string you entered in the input box. If
3837 an empty string is provided, no replacements are made.<br /><br />
3839 A more complex example. Say you have stored this query:<br /><br />
3840 <code>SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */</code>
3841 <br /><br />
3843 Say, you now enter &quot;phpMyAdmin&quot; as the variable for the stored query,
3844 the full query will be:<br /><br />
3846 <code>SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'</code>
3847 <br /><br />
3849 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query.<br />
3850 <b>NOTE THE ABSENCE OF SPACES</b> inside the &quot;/**/&quot; construct. Any
3851 spaces inserted there
3852 will be later also inserted as spaces in your query and may lead to unexpected
3853 results especially when
3854 using the variable expansion inside of a &quot;LIKE ''&quot; expression.<br />
3855 Your initial query which is going to be stored as a bookmark has to yield at
3856 least one result row so
3857 you can store the bookmark. You may have that to work around using well
3858 positioned &quot;/**/&quot; comments.</p>
3860 <h4 id="faq6_19">
3861 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to

3864 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
3865 document should look like following one (assuming you have table

3882 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
3883 enable users to see all the database names.
3884 See this <a href="http://bugs.mysql.com/179">bug report</a>.<br /><br />

3895 <a href="#faq6_6"><abbr title="Frequently Asked Questions">FAQ</abbr>
3896 6.6</a> for an example. Then, if there are 200 values or less in the

3898 You will see two lists of values, the first list containing the key
3899 and the display field, the second list containing the display field
3900 and the key. The reason for this is to be able to type the first
3901 letter of either the key or the display field.<br /><br />
3903 For 200 values or more, a distinct window will appear, to browse foreign
3904 key values and choose one.</p>

4030 <p> phpMyAdmin is Open Source, so you're invited to contribute to it. Many
4031 great features have been written by other people and you too can help to
4032 make phpMyAdmin a useful tool.</p>
4034 <p> If you're planning to contribute source, please read the following
4035 information:</p>
4037 <ul><li>All files include <i>libraries/header.inc.php</i> (layout),.
4038 <i>libraries/common.lib.php</i> (common functions) and
4039 <i>config.inc.php</i>.<br />
4040 Only configuration data should go in <i>config.inc.php</i>. Please keep
4041 it free from other code.<br />
4042 Commonly used functions should be added to
4043 <i>libraries/common.lib.php</i> and more specific ones may be added
4044 within a library stored into the <i>libraries</i> sub-directory.</li>
4045 <li>Obviously, you're free to use whatever coding style you want. But
4046 please try to keep your code as simple as possible: beginners are
4047 using phpMyAdmin as an example application.<br />
4048 As far as possible, we want the scripts to be XHTML1.0 and CSS2
4049 compliant on one hand, they fit the

4055 goes to <i>tbl_*.php</i>, db-related code to <i>db_*.php</i>,
4056 server-related tools to <i>server_*.php</i> and so on.</li>
4057 <li>Please don't use verbose strings in your code, instead add the string

4233 Original Credits of Version 2.1.0
4234 ---------------------------------
4236 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4237 to create a web-based interface to MySQL using PHP3. Although I have not
4238 used any of his source-code, there are some concepts I've borrowed from
4239 him. phpMyAdmin was created because Peter told me he wasn't going to
4240 further develop his (great) tool.
4241 Thanks go to
4242 - Amalesh Kempf &lt;ak-lsml_at_living-source.com&gt; who contributed the
4243 code for the check when dropping a table or database. He also suggested
4244 that you should be able to specify the primary key on tbl_create.php3. To
4245 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4246 well as a bug-report. Plus many smaller improvements.
4247 - Jan Legenhausen &lt;jan_at_nrw.net&gt;: He made many of the changes that
4248 were introduced in 1.3.0 (including quite significant ones like the
4249 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4250 bug-fixes and help.
4251 - Marc Delisle &lt;DelislMa_at_CollegeSherbrooke.qc.ca&gt; made phpMyAdmin
4252 language-independent by outsourcing the strings to a separate file. He
4253 also contributed the French translation.
4254 - Alexandr Bravo &lt;abravo_at_hq.admiral.ru&gt; who contributed
4255 tbl_select.php3, a feature to display only some fields from a table.
4256 - Chris Jackson &lt;chrisj_at_ctel.net&gt; added support for MySQL
4257 functions in tbl_change.php3. He also added the
4258 &quot;Query by Example&quot; feature in 2.0.
4259 - Dave Walton &lt;walton_at_nordicdms.com&gt; added support for multiple
4260 servers and is a regular contributor for bug-fixes.
4261 - Gabriel Ash &lt;ga244_at_is8.nyu.edu&gt; contributed the random access
4262 features for 2.0.6.
4263 The following people have contributed minor changes, enhancements, bugfixes
4264 or support for a new language:
4265 Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
4266 Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov,
4267 Sascha Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns,
4268 G. Wieggers.
4270 And thanks to everyone else who sent me email with suggestions, bug-reports
4271 and or just some feedback.
