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 separated 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> is still a quick way to get started and needed for some advanced features.
200 <ul><li>To manually create the file, simply use your text editor to
201 create the file <tt>config.inc.php</tt> (you can copy
202 <tt>config.sample.inc.php</tt> to get minimal configuration
203 file) in the main (top-level) phpMyAdmin directory (the one
204 that contains <tt>index.php</tt>). phpMyAdmin first loads
205 <tt>libraries/config.default.php</tt> and then overrides those
206 values with anything found in <tt>config.inc.php</tt>. If the
207 default value is okay for a particular setting, there is no
208 need to include it in <tt>config.inc.php</tt>. You'll need a
209 few directives to get going, a simple configuration may look
210 like this:
211 <pre>
212 &lt;?php
213 $cfg['blowfish_secret'] = 'ba17c1ec07d65003'; // use here a value of your choice
215 $i=0;
216 $i++;
217 $cfg['Servers'][$i]['auth_type'] = 'cookie';
218 ?&gt;
219 </pre>
220 Or, if you prefer to not be prompted every time you log in:
221 <pre>
222 &lt;?php
224 $i=0;
225 $i++;
226 $cfg['Servers'][$i]['user'] = 'root';
227 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
228 ?&gt;
229 </pre>
230 For a full explanation of possible configuration values, see the
231 <a href="#config">Configuration Section</a> of this document.</li>
232 <li id="setup_script">Instead of manually editing
233 <tt>config.inc.php</tt>, you can use the
234 <a href="setup/">Setup Script</a>. First you must
235 manually create a folder <tt>config</tt> in the phpMyAdmin
236 directory. This is a security measure. On a Linux/Unix system you
237 can use the following commands:
238 <pre>
239 cd phpMyAdmin
240 mkdir config # create directory for saving
241 chmod o+rw config # give it world writable permissions
242 </pre>
243 And to edit an existing configuration, copy it over first:
244 <pre>
245 cp config.inc.php config/ # copy current configuration for editing
246 chmod o+w config/config.inc.php # give it world writable permissions
247 </pre>
248 On other platforms, simply create the folder and ensure that your
249 web server has read and write access to it. <a href="#faq1_26">FAQ
250 1.26</a> can help with this.<br /><br />
252 Next, open <tt><a href="setup/">setup/</a>
253 </tt>in your browser. Note that <strong>changes are not saved to
254 disk until explicitly choose <tt>Save</tt></strong> from the
255 <i>Configuration</i> area of the screen. Normally the script saves
256 the new config.inc.php to the <tt>config/</tt> directory, but if
257 the webserver does not have the proper permissions you may see the
258 error "Cannot load or save configuration." Ensure that the <tt>
259 config/</tt> directory exists and has the proper permissions -
260 or use the <tt>Download</tt> link to save the config file locally
261 and upload (via FTP or some similar means) to the proper location.<br /><br />
263 Once the file has been saved, it must be moved out of the <tt>
264 config/</tt> directory and the permissions must be reset, again
265 as a security measure:
266 <pre>
267 mv config/config.inc.php . # move file to current directory
268 chmod o-rw config.inc.php # remove world read and write permissions
269 </pre>
270 Now the file is ready to be used. You can choose to review or edit
271 the file with your favorite editor, if you prefer to set some
272 advanced options which the setup script does not provide.</li></ul></li>
273 <li>If you are using the
274 <tt>auth_type</tt> &quot;config&quot;, it is suggested that you
275 protect the phpMyAdmin installation directory because using
276 config does not require a user to
277 enter a password to access the phpMyAdmin installation. Use of an alternate
278 authentication method is recommended, for example with
279 HTTP&#8211;AUTH in a <a href="#glossary"><i>.htaccess</i></a> file or switch to using
280 <tt>auth_type</tt> cookie or http. See the
281 <a href="#faqmultiuser"> multi&#8211;user sub&#8211;section</a> of this
282 <abbr title="Frequently Asked Questions">FAQ</abbr> for additional
283 information, especially <a href="#faq4_4">
284 <abbr title="Frequently Asked Questions">FAQ</abbr> 4.4</a>.</li>
285 <li>Open the <a href="index.php">main phpMyAdmin directory</a>
286 in your browser. phpMyAdmin should now display a welcome screen
287 and your databases, or a login dialog if using
288 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
289 authentication mode.</li>
290 <li>You should deny access to the <tt>./libraries</tt> subfolder in your
291 webserver configuration. For Apache you can use supplied .htaccess file
292 in that folder, for other webservers, you should configure this yourself.
293 Such configuration prevents from possible path exposure and cross side
294 scripting vulnerabilities that might happen to be found in that code.</li>
295 </ol>
297 <h3 id="linked-tables">Linked-tables infrastructure</h3>
299 <p> For a whole set of new features (bookmarks, comments,
300 <abbr title="structured query language">SQL</abbr>-history,
301 <abbr title="Portable Document Format">PDF</abbr>-generation, field contents
302 transformation, etc.) you need to create a set of special tables. Those
303 tables can be located in your own database, or in a central database for a
304 multi-user installation (this database would then be accessed by the
305 controluser, so no other user should have rights to it).</p>
307 <p> Please look at your <tt>./scripts/</tt> directory, where you should find a
308 file called <i>create_tables.sql</i>. (If you are using a Windows server, pay
309 special attention to <a href="#faq1_23">
310 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.23</a>).</p>
312 <p> If you already had this infrastructure and upgraded to MySQL 4.1.2
313 or newer, please use <i>./scripts/upgrade_tables_mysql_4_1_2+.sql</i>.</p>
315 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
316 that you may need special (administrator) privileges to create the database
317 and tables, and that the script may need some tuning, depending on the
318 database name.</p>
320 <p> After having imported the <i>./scripts/create_tables.sql</i> file, you
321 should specify the table names in your <i>./config.inc.php</i> file. The
322 directives used for that can be found in the <a href="#config">Configuration
323 section</a>. You will also need to have a controluser with the proper rights
324 to those tables (see section <a href="#authentication_modes">Using
325 authentication modes</a> below).</p>
327 <h3 id="upgrading">Upgrading from an older version</h3>
329 <p> Simply copy <i>./config.inc.php</i> from your previous installation into the newly
330 unpacked one. Configuration files from very old versions (2.3.0 or before) may
331 require some tweaking as some options have been changed or removed.
332 For compatibility with PHP 6, remove a <tt>set_magic_quotes_runtime(0);</tt>
333 statement that you might find near the end of your configuration file.</p>
335 <p> You should <strong>not</strong> copy <tt>libraries/config.default.php</tt>
336 over <tt>config.inc.php</tt> because the default configuration file
337 is version-specific.</p>
339 <p> If you have upgraded your MySQL server from a version previous to 4.1.2 to
340 version 4.1.2 or newer and if you use the pmadb/linked table infrastructure,
341 you should run the SQL script found in
342 <tt>scripts/upgrade_tables_mysql_4_1_2+.sql</tt>.</p>
344 <h3 id="authentication_modes">Using authentication modes</h3>
346 <ul><li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
347 authentication modes are recommended in a <b>multi-user environment</b>
348 where you want to give users access to their own database and don't want
349 them to play around with others.<br />
350 Nevertheless be aware that MS Internet Explorer seems to be really buggy
351 about cookies, at least till version 6, and PHP 4.1.1 is also a bit buggy
352 in this area!<br />
353 Even in a <b>single-user environment</b>, you might prefer to use
354 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie mode so
355 that your user/password pair are not in clear in the configuration file.
356 </li>
358 <li><abbr title="HyperText Transfer Protocol">HTTP</abbr> and cookie
359 authentication modes are more secure: the MySQL login information does
360 not need to be set in the phpMyAdmin configuration file (except possibly
361 for the <a href="#controluser">controluser</a>).<br />
362 However, keep in mind that the password travels in plain text, unless
363 you are using the HTTPS protocol.<br />
364 In cookie mode, the password is stored, encrypted with the blowfish
365 algorithm, in a temporary cookie.</li>
367 <li>Note: starting with phpMyAdmin 2.6.1, this section is only applicable if
368 your MySQL server is running with <tt>--skip-show-database</tt>.<br /><br />
370 For '<abbr title="HyperText Transfer Protocol">HTTP</abbr>' and 'cookie'
371 modes, phpMyAdmin needs a controluser that has <b>only</b> the
372 <tt>SELECT</tt> privilege on the <i>`mysql`.`user` (all columns except
373 `Password`)</i>, <i>`mysql`.`db` (all columns)</i>, <i>`mysql`.`host`
374 (all columns)</i> and <i>`mysql`.`tables_priv` (all columns except
375 `Grantor` and `Timestamp`)</i> tables.<br /> You must specify the details
376 for the <a href="#controluser">controluser</a> in the <tt>config.inc.php</tt>
377 file under the
378 <tt><a href="#cfg_Servers_controluser" class="configrule">
379 $cfg['Servers'][$i]['controluser']</a></tt> and
380 <tt><a href="#cfg_Servers_controlpass" class="configrule">
381 $cfg['Servers'][$i]['controlpass']</a></tt> settings.<br />
382 The following example assumes you want to use <tt>pma</tt> as the
383 controluser and <tt>pmapass</tt> as the controlpass, but <b>this is
384 only an example: use something else in your file!</b> Input these
385 statements from the phpMyAdmin SQL Query window or mysql command&#8211;line
386 client.<br />
387 Of course you have to replace <tt>localhost</tt> with the webserver's host
388 if it's not the same as the MySQL server's one.
390 <pre>
391 GRANT USAGE ON mysql.* TO 'pma'@'localhost' IDENTIFIED BY 'pmapass';
392 GRANT SELECT (
393 Host, User, Select_priv, Insert_priv, Update_priv, Delete_priv,
394 Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv,
395 File_priv, Grant_priv, References_priv, Index_priv, Alter_priv,
396 Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv,
397 Execute_priv, Repl_slave_priv, Repl_client_priv
398 ) ON mysql.user TO 'pma'@'localhost';
399 GRANT SELECT ON mysql.db TO 'pma'@'localhost';
400 GRANT SELECT ON mysql.host TO 'pma'@'localhost';
401 GRANT SELECT (Host, Db, User, Table_name, Table_priv, Column_priv)
402 ON mysql.tables_priv TO 'pma'@'localhost';</pre>
404 If you want to use the many new relation and bookmark features:
406 <pre>
407 GRANT SELECT, INSERT, UPDATE, DELETE ON &lt;pma_db&gt;.* TO 'pma'@'localhost';
408 </pre>
410 (this of course requires that your <a href="#linked-tables">linked-tables
411 infrastructure</a> be set up).<br /></li>
413 <li>Then each of the <i>true</i> users should be granted a set of privileges
414 on a set of particular databases. Normally you shouldn't give global
415 privileges to an ordinary user, unless you understand the impact of those
416 privileges (for example, you are creating a superuser).<br />
417 For example, to grant the user <i>real_user</i> with all privileges on
418 the database <i>user_base</i>:<br />
420 <pre>
421 GRANT ALL PRIVILEGES ON user_base.* TO 'real_user'@localhost IDENTIFIED BY 'real_password';
422 </pre>
424 What the user may now do is controlled entirely by the MySQL user
425 management system.<br />
426 With <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie
427 authentication mode, you don't need to fill the user/password fields
428 inside the <a href="#cfg_Servers" class="configrule">$cfg['Servers']</a>
429 array.</li>
430 </ul>
432 <h4>'<abbr title="HyperText Transfer Protocol">HTTP</abbr>' authentication mode</h4>

463 <a href="#AllowArbitraryServer" class="configrule">
464 $cfg['AllowArbitraryServer']</a> directive.</li>
465 <li>As mentioned in the <a href="#require">requirements</a> section, having

470 <h4>'signon' authentication mode</h4>
472 <ul><li>This mode is a convenient way of using credentials from another
473 application to authenticate to phpMyAdmin.</li>
474 <li>The other application has to store login information into
475 session data.</li>
476 <li>More details in the <a href="#cfg_Servers_auth_type">auth_type</a>
477 section.</li>
478 </ul>
479 <h4>'config' authentication mode</h4>
481 <ul><li>This mode is the less secure one because it requires you to fill the
482 <a href="#servers_user" class="configrule">
483 $cfg['Servers'][$i]['user']</a> and
484 <a href="#servers_user" class="configrule">
485 $cfg['Servers'][$i]['password']</a> fields (and as a result, anyone who
486 can read your config.inc.php can discover your username and password).
487 <br />
488 But you don't need to setup a &quot;controluser&quot; here: using the
489 <a href="#servers_only_db" class="configrule">
490 $cfg['Servers'][$i]['only_db']</a> might be enough.</li>
491 <li>In the <a href="#faqmultiuser">
492 <abbr title="Internet service provider">ISP</abbr>
493 <abbr title="Frequently Asked Questions">FAQ</abbr></a> section, there
494 is an entry explaining how to protect your configuration file.</li>
495 <li>For additional security in this mode, you may wish to consider the Host
496 authentication
497 <a href="#servers_allowdeny_order" class="configrule">
498 $cfg['Servers'][$i]['AllowDeny']['order']</a> and
499 <a href="#servers_allowdeny_rules" class="configrule">
500 $cfg['Servers'][$i]['AllowDeny']['rules']</a> configuration
501 directives.</li>
502 <li>Unlike cookie and http, does not require a user to log in when first
503 loading the phpMyAdmin site. This is by design but could allow any
504 user to access your installation. Use of some restriction method is
505 suggested, perhaps a <a href="#glossary">.htaccess</a> file with the
506 HTTP-AUTH directive or disallowing incoming HTTP requests at
507 one&#8217;s router or firewall will suffice (both of which
508 are beyond the scope of this manual but easily searchable with Google).</li>
509 </ul>
510 <h4 id="swekey">Swekey authentication</h4>
512 The Swekey is a low cost authentication USB key that can be used in
513 web applications.<br /><br />
514 When Swekey authentication is activated, phpMyAdmin requires the
515 users's Swekey to be plugged before entering the login page (currently
516 supported for cookie authentication mode only). Swekey Authentication is
517 disabled by default.<br /><br />
518 To enable it, add the following line to <tt>config.inc.php</tt>:
519 </p>
520 <pre>
521 $cfg['Servers'][$i]['auth_swekey_config'] = './swekey.conf';
522 </pre>
524 You then have to create the <tt>swekey.conf</tt> file that will associate
525 each user with their Swekey Id. A self documented sample file is provided
526 in the <tt>contrib</tt> directory. Feel free to use it with your own
527 users' information.<br /><br />
528 If you want to purchase a Swekey please visit
529 <a href="http://phpmyadmin.net/auth_key">http://phpmyadmin.net/auth_key</a>
530 since this link provides funding for phpMyAdmin.

560 Don&#8217;t forget the trailing slash at the end.<br /><br />
562 Starting with version 2.3.0, it is advisable to try leaving this
563 blank. In most cases phpMyAdmin automatically detects the proper
564 setting. Users of port forwarding will need to set PmaAbsoluteUri (<a

566 A good test is to browse a table, edit a row and save it. There should
567 be an error message if phpMyAdmin is having trouble auto&#8211;detecting
568 the correct value. If you get an error that this must be set or if
569 the autodetect code fails to detect your path, please post a bug

600 number of characters for this parameter seems to be 46.<br /><br />
602 Since version 3.1.0 phpMyAdmin can generate this on the fly, but it

707 <li>'cookie' authentication mode
708 (<tt>$auth_type&nbsp;=&nbsp;'cookie'</tt>) as introduced in
709 2.2.3 allows you to log in as any valid MySQL user with the
710 help of cookies. Username and password are stored in
711 cookies during the session and password is deleted when it
712 ends. This can also allow you to log in in arbitrary server if

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

796 For example, to hide all databases starting with the letter &#34;a&#34;, use<br />

910 <dd>Since release 2.3.0 you can have phpMyAdmin create
911 <abbr title="Portable Document Format">PDF</abbr> pages showing
912 the relations between your tables. To do this it needs two tables
913 &quot;pdf_pages&quot; (storing information about the available
914 <abbr title="Portable Document Format">PDF</abbr>
915 pages) and &quot;table_coords&quot; (storing coordinates where each
916 table will be placed on a <abbr title="Portable Document Format">PDF</abbr>
917 schema output).<br /><br />
919 You must be using the &quot;relation&quot; feature.<br /><br />
921 To allow the usage of this functionality:
923 <ul><li>set up <a href="#pmadb">pmadb</a> and the linked-tables
924 infrastructure</li>
925 <li>put the correct table names in
926 <tt>$cfg['Servers'][$i]['table_coords']</tt> and
927 <tt>$cfg['Servers'][$i]['pdf_pages']</tt></li>

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

978 <dd>Since release 2.5.0 you can store your
979 <abbr title="structured query language">SQL</abbr> history, which means
980 all queries you entered manually into the phpMyAdmin interface. If you
981 don't want to use a table-based history, you can use the JavaScript-based
982 history. Using that, all your history items are deleted when closing the
983 window.<br /><br />
985 Using
986 <a href="#cfg_QueryHistoryMax" class="configrule">$cfg['QueryHistoryMax']</a>
987 you can specify an amount of history items you want to have on hold. On
988 every login, this list gets cut to the maximum amount.<br /><br />
990 The query history is only available if JavaScript is enabled in your
991 browser.<br /><br />
993 To allow the usage of this functionality:
995 <ul><li>set up <a href="#pmadb">pmadb</a> and the linked-tables

1026 You can disable this checking behavior by setting the variable to false,

1029 Recommended to set to FALSE, when you are sure, your table structure is

1036 boolean</dt>

1045 authentication is disabled.<br /><br />
1047 If your rule order is set to <tt>'deny,allow'</tt> then the system applies
1048 all deny rules followed by allow rules. Access is allowed by default. Any
1049 client which does not match a Deny command or does match an Allow command
1050 will be allowed access to the server. <br /><br />
1052 If your rule order is set to <tt>'allow,deny'</tt> then the system
1053 applies all allow rules followed by deny rules. Access is denied by
1054 default. Any client which does not match an Allow directive or does
1055 match a Deny directive will be denied access to the server.<br /><br />
1057 If your rule order is set to 'explicit', the authentication is
1058 performed in a similar fashion to rule order 'deny,allow', with the
1059 added restriction that your host/username combination <b>must</b> be
1060 listed in the <i>allow</i> rules, and not listed in the <i>deny</i>
1061 rules. This is the <b>most</b> secure means of using Allow/Deny rules,
1062 and was available in Apache by specifying allow and deny rules without
1063 setting any order.<br /><br />

1078 If you wish to match all users, it is possible to use a <tt>'%'</tt> as

1080 There are a few shortcuts you can use in the <i>ipmask</i> field as

1088 'localnetC' -&gt; SERVER_ADDRESS/24

1091 Having an empty rule list is equivalent to either using
1092 <tt>'allow % from all'</tt> if your rule order is set to
1093 <tt>'deny,allow'</tt> or <tt>'deny % from all'</tt> if your rule order

1281 to split/nest the tables according to the
1282 <a href="#cfg_LeftFrameTableSeparator" class="configrule">$cfg['LeftFrameTableSeparator']</a>
1283 directive. So only the folder is called like the Alias, the tablename itself
1284 stays the real tablename.</dd>

1310 <dt id="cfg_LeftDefaultTabTable">$cfg['LeftDefaultTabTable'] string</dt>
1311 <dd>Defines the tab displayed by default when clicking the small

1333 <dd>Defines whether to display the &quot;PHP information&quot; and
1334 &quot;Change password &quot; links and form for creating database or
1335 not at the starting main (right) frame. This setting
1336 does not check MySQL commands entered directly.<br /><br />
1338 Please note that to block the usage of phpinfo() in scripts, you
1339 have to put this in your <i>php.ini</i>:
1341 <pre>disable_functions = phpinfo()</pre>
1343 Also note that enabling the &quot;Change password &quot; link has no
1344 effect with &quot;config&quot; authentication mode: because of the

1798 <tt>open_basedir</tt> restriction, you need to create a
1799 temporary directory in some directory accessible by the web
1800 server. However for security reasons, this directory should be outside
1801 the tree published by webserver. If you cannot avoid having this
1802 directory published by webserver, place at least an empty
1803 <tt>index.html</tt> file there, so that directory listing is not
1804 possible.
1805 <br /><br />
1807 This directory should have as strict permissions as possible as the only
1808 user required to access this directory is the one who runs the
1809 webserver. If you have root privileges, simply make this user owner of
1810 this directory and make it accessible only by it:
1811 <br /><br />
1813 <pre>
1814 chown www-data:www-data tmp
1815 chmod 700 tmp
1816 </pre>
1818 If you cannot change owner of the directory, you can achieve a similar
1819 setup using <abbr title="Access Control List">ACL</abbr>:
1821 <pre>
1822 chmod 700 tmp
1823 setfacl -m "g:www-data:rwx" tmp
1824 setfacl -d -m "g:www-data:rwx" tmp
1825 </pre>
1827 If neither of above works for you, you can still make the directory
1828 <code>chmod 777</code>, but it might impose risk of other users on
1829 system reading and writing data in this directory.

1859 All those variables affect the query window feature. A <tt><abbr title="structured query language">SQL</abbr></tt> link
1860 or icon is always displayed on the left panel. If JavaScript is enabled in
1861 your browser, a click on this opens a distinct query window, which is
1862 a direct interface to enter <abbr title="structured query language">SQL</abbr> queries. Otherwise, the right panel
1863 changes to display a query box.<br /><br />
1865 The size of this query window can be customized with
1866 <tt>$cfg['QueryWindowWidth']</tt> and <tt>$cfg['QueryWindowWidth']</tt>
1867 - both integers for the size in pixels. Note that normally, those
1868 parameters will be modified in <tt>layout.inc.php</tt> for the
1869 theme you are using.<br /><br />
1871 If <tt>$cfg['EditInWindow']</tt> is set to true, a click on [Edit]
1872 from the results page (in the &quot;Showing Rows&quot; section)
1873 opens the query window and puts the current query
1874 inside it. If set to false, clicking on the link puts the <abbr title="structured query language">SQL</abbr>
1875 query in the right panel's query box.
1876 <br /><br />
1877 The usage of the JavaScript query window is recommended if you have a
1878 JavaScript enabled browser. Basic functions are used to exchange quite
1879 a few variables, so most 4th generation browsers should be capable to
1880 use that feature. It currently is only tested with Internet Explorer 6
1881 and Mozilla 1.x.
1882 <br /><br />
1883 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt>, all your Queries are logged
1884 to a table, which has to be created by you (see <a
1885 href="#history" class="configrule">$cfg['Servers'][$i]['history']</a>). If set to FALSE,
1886 all your queries will be appended to the form, but only as long as
1887 your window is opened they remain saved.
1888 <br /><br />
1889 When using the JavaScript based query window, it will always get
1890 updated when you click on a new table/db to browse and will focus if
1891 you click on "Edit <abbr title="structured query language">SQL</abbr>" after using a query. You can suppress updating
1892 the query window by checking the box "Do not overwrite this query from
1893 outside the window" below the query textarea. Then you can browse
1894 tables/databases in the background without losing the contents of the
1895 textarea, so this is especially useful when composing a query with
1896 tables you first have to look in. The checkbox will get automatically
1897 checked whenever you change the contents of the textarea. Please
1898 uncheck the button whenever you definitely want the query window to
1899 get updated even though you have made alterations.
1900 <br /><br />
1901 If <tt>$cfg['QueryHistoryDB']</tt> is set to <tt>TRUE</tt> you can specify the amount of
1902 saved history items using <tt>$cfg['QueryHistoryMax']</tt>.
1903 <br /><br />
1904 The query window also has a custom tabbed look to group the features.
1905 Using the variable <tt>$cfg['QueryWindowDefTab']</tt> you can specify the
1906 default tab to be used when opening the query window. It can be set to
1907 either 'sql', 'files', 'history' or 'full'.</dd>

1932 where you edit x/y coordinates of those elements you can activate a
1933 scratchboard where all your elements are placed. By clicking on an
1934 element, you can move them around in the pre-defined area and the x/y
1935 coordinates will get updated dynamically. Likewise, when entering a
1936 new position directly into the input field, the new position in the
1937 scratchboard changes after your cursor leaves the input field.<br />
1938 You have to click on the 'OK'-button below the tables to save the new
1939 positions. If you want to place a new element, first add it to the
1940 table of elements and then you can drag the new element around.<br />
1941 By changing the paper size and the orientation you can change the size
1942 of the scratchboard as well. You can do so by just changing the
1943 dropdown field below, and the scratchboard will resize automatically,
1944 without interfering with the current placement of the elements.<br />
1945 If ever an element gets out of range you can either enlarge the paper
1946 size or click on the 'reset' button to place all elements below each
1947 other.<br />

2171 <ol><li><a href="#transformationsintro">Introduction</a></li>
2172 <li><a href="#transformationshowto">Usage</a></li>
2173 <li><a href="#transformationsfiles">File structure</a></li>
2174 </ol>
2176 <h3 id="transformationsintro">1. Introduction</h3>
2178 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2179 and the proper directives. Please see the <a href="#config">Configuration
2180 section</a> on how to do so.</p>
2182 <p> You can apply different transformations to the contents of each field. The
2183 transformation will take the content of each field and transform it with
2184 certain rules defined in the selected transformation.</p>
2186 <p> Say you have a field 'filename' which contains a filename. Normally you would
2187 see in phpMyAdmin only this filename. Using transformations you can transform
2188 that filename into a HTML link, so you can click inside of the phpMyAdmin
2189 structure on the field's link and will see the file displayed in a new browser
2190 window. Using transformation options you can also specify strings to
2191 append/prepend to a string or the format you want the output stored in.</p>
2193 <p> For a general overview of all available transformations and their options,
2194 you can consult your
2195 <i>&lt;www.your-host.com&gt;/&lt;your-install-dir&gt;/transformation_overview.php</i>
2196 installation.</p>
2198 <p> For a tutorial on how to effectively use transformations, see our
2199 <a href="http://www.phpmyadmin.net/home_page/docs.php">Link section</a> on
2200 the official phpMyAdmin homepage.</p>
2202 <h3 id="transformationshowto">2. Usage</h3>
2204 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2205 clicking on the 'Structure' link for a table). There click on
2206 &quot;Change&quot; (or change icon) and there you will see three new fields at
2207 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2208 'Transformation options'.</p>
2210 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2211 that corresponds to the column's contents. Please note that
2212 transformations are inactive as long as no MIME-type is selected.</li>
2214 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2215 hopefully growing amount of pre-defined transformations. See below for information on
2216 how to build your own transformation.<br />
2218 There are global transformations and mimetype-bound transformations. Global transformations
2219 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2220 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2221 transformations which operate on the main mimetype (like 'image'), which will most likely
2222 take the subtype into regard, and those who only operate on a
2223 specific subtype (like 'image/jpeg').<br />
2225 You can use transformations on mimetypes for which the function was not defined for. There
2226 is no security check for you selected the right transformation, so take care of what the
2227 output will be like.</li>
2229 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2230 transform-function specific options here. Usually the transforms can operate with default
2231 options, but it is generally a good idea to look up the overview to see which options are
2232 necessary.<br />
2234 Much like the ENUM/SET-Fields, you have to split up several options using the format
2235 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2236 parsed as an array, leaving the first value the first element in the array, and so
2237 forth.<br />
2239 If you want to specify a MIME character set you can define it in the transformation_options.
2240 You have to put that outside of the pre-defined options of the specific mime-transform,
2241 as the last value of the set. Use the format "'; charset=XXX'". If you use a transform,
2242 for which you can specify 2 options and you want to append a character set, enter "'first
2243 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2244 the parameters: "'','','charset=us-ascii'".</li>
2245 </ul>
2247 <h3 id="transformationsfiles">3. File structure</h3>
2249 <p> All mimetypes and their transformations are defined through single files in
2250 the directory 'libraries/transformations/'.</p>
2252 <p> They are stored in files to ease up customization and easy adding of new
2253 transformations.</p>
2255 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2256 always work. It makes no sense to apply a transformation to a mimetype, the
2257 transform-function doesn't know to handle.</p>
2259 <p> One can, however, use empty mime-types and global transformations which should work
2260 for many mimetypes. You can also use transforms on a different mimetype they where built
2261 for, but pay attention to option usage as well as what the transformation does to your
2262 field.</p>
2264 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2265 any other transform function and provides some basic functions.</p>
2267 <p> There are 5 possible file names:</p>
2269 <ol><li>A mimetype+subtype transform:<br /><br />
2271 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2273 Please not that mimetype and subtype are separated via '_', which shall
2274 not be contained in their names. The transform function/filename may
2275 contain only characters which cause no problems in the file system as
2276 well as the PHP function naming convention.<br /><br />
2278 The transform function will the be called
2279 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2281 <b>Example:</b><br /><br />
2283 <tt>text_html__formatted.inc.php</tt><br />
2284 <tt>PMA_transform_text_html__formatted()</tt></li>
2286 <li>A mimetype (w/o subtype) transform:<br /><br />
2288 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2290 Please note that there are no single '_' characters.
2291 The transform function/filename may contain only characters which cause
2292 no problems in the file system as well as the PHP function naming
2293 convention.<br /><br />
2295 The transform function will the be called
2296 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2298 <b>Example:</b><br /><br />
2300 <tt>text__formatted.inc.php</tt><br />
2301 <tt>PMA_transform_text__formatted()</tt></li>
2303 <li>A mimetype+subtype without specific transform function<br /><br />
2305 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2307 Please note that there are no '__' characters in the filename. Do not
2308 use special characters in the filename causing problems with the file
2309 system.<br /><br />
2311 No transformation function is defined in the file itself.<br /><br />
2313 <b>Example:</b><br /><br />
2315 <tt>text_plain.inc.php</tt><br />
2316 (No function)</li>
2318 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2320 <tt>[mimetype].inc.php</tt><br /><br />
2322 Please note that there are no '_' characters in the filename. Do not use
2323 special characters in the filename causing problems with the file system.
2324 <br /><br />
2326 No transformation function is defined in the file itself.<br /><br />
2328 <b>Example:</b><br /><br />
2330 <tt>text.inc.php</tt><br />
2331 (No function)</li>
2333 <li>A global transform function with no specific mimetype<br /><br />
2335 <tt>global__[transform].inc.php</tt><br /><br />
2337 The transform function will the be called
2338 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2340 <b>Example:</b><br /><br />
2342 <tt>global__formatted</tt><br />
2343 <tt>PMA_transform_global__formatted()</tt></li>
2344 </ol>
2346 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2347 transform function.</p>
2349 <p> All filenames containing no '__' in themselves are not shown as valid transform
2350 functions in the dropdown.</p>
2352 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2353 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2354 without a transform function. Also note the introduction of a function description in
2355 the language files. For each function a $strTransformation_[filename without .inc.php]
2356 has to exist.</p>
2358 <p> You can use the template generator to generate new functions and entries in the
2359 language file.</p>
2361 <p> To create a new transform function please see
2362 <tt>libraries/transformations/template_generator.sh</tt>.
2363 To create a new, empty mimetype please see
2364 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2366 <p> A transform function always gets passed three variables:</p>
2368 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2369 you want to transform.</li>
2370 <li><b>$options</b> - Contains any user-passed options to a transform function
2371 as an array.</li>
2372 <li><b>$meta</b> - Contains an object with field information to your column.
2373 The data is drawn from the output of the
2374 <a href="http://www.php.net/mysql_fetch_field">mysql_fetch_field()</a>
2375 function. This means, all object properties described on the
2376 <a href="http://www.php.net/mysql_fetch_field">manual page</a> are
2377 available in this variable and can be used to transform a field accordingly
2378 to unsigned/zerofill/not_null/... properties.<br />
2379 The $meta-&gt;mimetype variable contains the original MIME-type of the
2380 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2381 </ol>

2488 <p> Your uploaded file is saved by PHP in the &quot;upload dir&quot;, as
2489 defined in <i>php.ini</i> by the variable <tt>upload_tmp_dir</tt> (usually
2490 the system default is <i>/tmp</i>).<br />
2491 We recommend the following setup for Apache servers running in safe mode,

2494 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2495 <li>give ownership to the Apache server's user.group:

2508 and you updated your PHP RPM to php-4.0.4pl1-3.i386.rpm, didn't you?<br />
2509 So the problem is that this package has a serious bug that was corrected
2510 ages ago in PHP (2001-01-28: see
2511 <a href="http://www.php.net/bugs.php?id=8966">PHP's bug tracking system</a>
2512 for more details). The problem is that the bugged package is still

2537 <p> Since version 2.2.4, phpMyAdmin supports servers with open_basedir

2539 configure it as <a href="#cfg_TempDir" class="configrule">$cfg['TempDir']</a>.

2575 <a href="#faq1_16">1.16 I cannot upload big dump files (memory,
2576 <abbr title="HyperText Transfer Protocol">HTTP</abbr> or timeout problems).</a>
2577 </h4>
2579 <p> Starting with version 2.7.0, the import engine has been re&#8211;written and these
2580 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2581 to take advantage of the new import features.</p>
2583 <p> The first things to check (or ask your host provider to check) are the
2584 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2585 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2586 All of these three settings limit the maximum size of data that can be
2587 submitted and handled by PHP. One user also said that post_max_size
2588 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2590 There exist several workarounds if your upload is too big or your
2591 hosting provider is unwilling to change the settings:</p>
2593 <ul><li>Look at the <a href="#cfg_UploadDir" class="configrule">$cfg['UploadDir']</a>
2594 feature. This allows one to
2595 upload a file to the server via scp, ftp, or your favorite file transfer
2596 method. PhpMyAdmin is then able to import the files from the temporary
2597 directory. More information is available in the <a href="#config">Configuration
2598 section</a> of this document.</li>
2599 <li>Using a utility (such as <a href="http://www.ozerov.de/bigdump.php">
2600 BigDump</a>) to split the files before uploading. We cannot support this
2601 or any third party applications, but are aware of users having success
2602 with it.</li>
2603 <li>If you have shell (command line) access, use MySQL to import the files
2604 directly. You can do this by issuing the &quot;source&quot; command from
2605 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2606 </ul>
2608 <h4 id="faq1_17">
2609 <a id="faqmysqlversions" href="#faq1_17">1.17 Which MySQL versions does phpMyAdmin
2610 support?</a></h4>
2612 <p> In phpMyAdmin 3.0.x, versions starting with MySQL 5.0.1 are
2613 fully supported. phpMyAdmin may connect to your MySQL server
2614 using PHP's classic
2615 <a href="http://php.net/mysql">MySQL extension</a> as well as the
2616 <a href="http://php.net/mysqli">improved MySQL extension (MySQLi)</a> that
2617 is available in php 5.0.<br />
2618 Either way, the developers of both extensions recommend to use the classic
2619 extension for MySQL 4.0 and below and MySQLi for MySQL 4.1 and newer.<br />
2620 When compiling php, we strongly recommend that you manually link the MySQL
2621 extension of your choice to a MySQL client library of at least the same
2622 minor version since the one that is bundled with some PHP distributions is
2623 rather old and might cause problems <a href="#faq1_17a">
2624 (see <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17a)</a>.
2625 If your webserver is running on a windows system, you might want to try
2626 MySQL's
2627 <a href="http://dev.mysql.com/downloads/connector/php/">Connector/PHP</a>
2628 instead of the MySQL / MySQLi extensions that are bundled with the official
2629 php Win32 builds.</p>
2631 <h5 id="faq1_17a">
2632 <a href="#faq1_17a">1.17a I cannot connect to the MySQL server. It always returns the error
2633 message, &quot;Client does not support authentication protocol requested
2634 by server; consider upgrading MySQL client&quot;</a></h5>
2636 <p> You tried to access MySQL with an old MySQL client library. The version of
2637 your MySQL client library can be checked in your phpinfo() output.
2638 In general, it should have at least the same minor version as your server
2639 - as mentioned in <a href="#faq1_17">
2640 <abbr title="Frequently Asked Questions">FAQ</abbr> 1.17</a>.<br /><br />
2642 This problem is generally caused by using MySQL version 4.1 or newer. MySQL
2643 changed the authentication hash and your PHP is trying to use the old method.
2644 The proper solution is to use the <a href="http://www.php.net/mysqli">mysqli extension</a>
2645 with the proper client library to match your MySQL installation. Your
2646 chosen extension is specified in <a href="#cfg_Servers_extension" class="configrule">$cfg['Servers'][$i]['extension']</a>.

2931 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
2933 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
2934 In your <i>php.ini</i> you will find a line</p>
2936 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
2938 <p> change it to</p>
2940 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
2942 <p> Then restart apache and it will work.</p>
2944 <p> Here is a fix suggested by Brad Ummer:</p>
2946 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
2947 To do this, telnet to your server and go to the MySQL bin directory. In
2948 this directory there should be a file named <i>mysqladmin</i>. Type
2949 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
2950 info about your MySQL server, including the socket
2951 (<i>/tmp/mysql.sock</i>, for example).</li>
2952 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
2953 phpMyAdmin, you need to complete the socket information in the
2954 <i>config.inc.php</i>.<br />
2955 For example:
2956 <a href="#cfg_Servers_socket" class="configrule">
2957 $cfg['Servers'][$i]['socket']&nbsp;=&nbsp;'/tmp/mysql.sock';</a>
2958 <br /><br />
2960 Please also make sure that the permissions of this file allow to be readable
2961 by your webserver (i.e. '0755').</li>
2962 </ul>
2964 <p> Have also a look at the
2965 <a href="http://www.mysql.com/doc/C/a/Can_not_connect_to_server.html">
2966 corresponding section of the MySQL documentation</a>.</p>

2993 <p> When you are using a port on your localhost, which you redirect via
2994 port-forwarding to another host, MySQL is not resolving the localhost
2995 as expected.<br />
2996 Erik Wasser explains: The solution is: if your host is &quot;localhost&quot;
2997 MySQL (the commandline tool 'mysql' as well) always tries to use the socket
2998 connection for speeding up things. And that doesn't work in this configuration
2999 with port forwarding.<br />

3007 <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a> and
3008 <a href="#cfg_ThemeDefault" class="configrule">$cfg['ThemeDefault']</a>.<br />
3009 <br />
3010 Under <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>, you
3011 should not delete the directory &quot;original&quot; or its underlying
3012 structure, because this is the system theme used by phpMyAdmin.
3013 &quot;original&quot; contains all images and styles, for backwards
3014 compatibility and for all themes that would not include images or css-files.
3015 <br /><br />
3017 If <a href="#cfg_ThemeManager" class="configrule">$cfg['ThemeManager']</a>
3018 is enabled, you can select your favorite theme on the main page. Your
3019 selected theme will be stored in a cookie.<br /><br /></p>
3021 <p> To create a theme:</p>
3023 <ul><li>make a new subdirectory (for example &quot;your_theme_name&quot;) under
3024 <a href="#cfg_ThemePath" class="configrule">$cfg['ThemePath']</a>
3025 (by default <tt>themes</tt>)</li>
3026 <li>copy the files and directories from &quot;original&quot; to
3027 &quot;your_theme_name&quot;</li>
3028 <li>edit the css-files in &quot;your_theme_name/css&quot;</li>
3029 <li>put your new images in &quot;your_theme_name/img&quot;</li>
3030 <li>edit <tt>layout.inc.php</tt> in &quot;your_theme_name&quot;</li>
3031 <li>edit <tt>info.inc.php</tt> in &quot;your_theme_name&quot; to
3032 contain your chosen theme name, that will be visible in user interface</li>
3033 <li>make a new screenshot of your theme and save it under
3034 &quot;your_theme_name/screen.png&quot;</li>
3035 </ul>
3037 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
3038 theme verbose name, theme generation and theme version. These versions and
3039 generations are enumerated from 1 and do not have any direct dependence on
3040 phpMyAdmin version. Themes within same generation should be backwards
3041 compatible - theme with version 2 should work in phpMyAdmin requiring
3042 version 1. Themes with different generation are incompatible.</p>
3044 <p> If you do not want to use your own symbols and buttons, remove the
3045 directory &quot;img&quot; in &quot;your_theme_name&quot;. phpMyAdmin will
3046 use the default icons and buttons (from the system-theme &quot;original&quot;).

3172 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no

3174 You can, however, use any form inside of a table if keep the parent
3175 form-container with the target to tbl_row_delete.php and just put your own
3176 input-elements inside. If you use a custom submit input field, the form will
3177 submit itself to the displaying page again, where you can validate the

3261 </a></h4>
3263 This depends on your system.<br />
3264 If you're running a server which cannot be accessed by other people, it's
3265 sufficient to use the directory protection bundled with your webserver
3266 (with Apache you can use <i>.htaccess</i> files, for example).<br />
3267 If other people have telnet access to your server, you should use
3268 phpMyAdmin's <abbr title="HyperText Transfer Protocol">HTTP</abbr> or cookie authentication features.

3270 Suggestions:
3271 </p>
3272 <ul>
3273 <li>
3274 Your <i>config.inc.php</i> file should be <tt>chmod 660</tt>.
3275 </li>
3276 <li>
3277 All your phpMyAdmin files should be chown -R phpmy.apache, where phpmy
3278 is a user whose password is only known to you, and apache is the
3279 group under which Apache runs.
3280 </li>
3281 <li>
3282 You should use PHP safe mode, to protect from other users that try
3283 to include your <i>config.inc.php</i> in their scripts.

3320 and put the privileges you want. For example,

3754 if it already exists during the import. It does NOT drop the table after
3755 your export, it only affects the import file.</li>
3756 <li>&quot;If Not Exists&quot; will only create the table if it doesn't exist.
3757 Otherwise, you may get an error if the table name exists but has a
3758 different structure.</li>
3759 <li>&quot;Add AUTO_INCREMENT value&quot; ensures that AUTO_INCREMENT value
3760 (if any) will be included in backup.</li>

3789 <p> This is a bad idea, because in MySQL the syntax &quot;database.table&quot;

3794 <h4 id="faqsqlvalidator">
3795 <a href="#faqsqlvalidator">6.14 How do I set up the
3796 <abbr title="structured query language">SQL</abbr> Validator?</a></h4>
3798 <p> To use it, you need a very recent version of PHP, 4.3.0 recommended, with
3799 <abbr title="Extensible Markup Language">XML</abbr>,
3800 <abbr title="Perl Compatible Regular Expressions">PCRE</abbr> and
3801 <abbr title="PHP Extension and Application Repository">PEAR</abbr> support.
3802 On your system command line, run <tt>"pear install Net_Socket Net_URL
3803 HTTP_Request Mail_Mime Net_DIME SOAP"</tt> to get the necessary
3804 <abbr title="PHP Extension and Application Repository">PEAR</abbr> modules
3805 for usage.<br />
3806 On a more recent pear version, I had problems with the state of Net_DIME
3807 being beta, so this single command
3808 <tt>"pear -d preferred_state=beta install -a SOAP"</tt> installed all the
3809 needed modules.<br />
3810 If you use the Validator, you should be aware that any
3811 <abbr title="structured query language">SQL</abbr> statement you
3812 submit will be stored anonymously (database/table/column names,
3813 strings, numbers replaced with generic values). The Mimer
3814 <abbr title="structured query language">SQL</abbr>

3820 it, but MySQL says &quot;BLOB column '...' used in key specification without
3821 a key length&quot;.</a></h4>
3823 <p> The right way to do this, is to create the field without any indexes,
3824 then display the table structure and use the &quot;Create an index&quot;
3825 dialog. On this page, you will be able to choose your BLOB field, and
3826 set a size to the index, which is the condition to create an index on

3830 <a href="#faq6_16">6.16 How can I simply move in page with plenty

3835 (must be enabled in configuration - see.

3837 You can also have a look at the directive

3842 <a href="#faq6_17">6.17 Transformations: I can't enter my own mimetype!
3843 WTF is this feature then useful for?</a></h4>
3845 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
3846 on them. Otherwise you could just put a comment on the field. Because entering
3847 your own mimetype will cause serious syntax checking issues and validation,
3848 this introduces a high-risk false-user-input situation. Instead you have to
3849 initialize mimetypes using functions or empty mimetype definitions.<br />
3850 Plus, you have a whole overview of available mimetypes. Who knows all those
3851 mimetypes by heart so he/she can enter it at will?</p>

3854 <a href="#faqbookmark">6.18 Bookmarks: Where can I store bookmarks? Why
3855 can't I see any bookmarks below the query box? What is this variable for?
3856 </a></h4>
3858 <p> Any query you have executed can be stored as a bookmark on the page where the
3859 results are displayed. You will find a button labeled 'Bookmark this query'
3860 just at the end of the page.<br />
3861 As soon as you have stored a bookmark, it is related to the database you run
3862 the query on. You can now access a bookmark dropdown on each page, the query
3863 box appears on for that database.<br /><br />
3865 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
3866 Just use the string <b>/*[VARIABLE]*/</b> anywhere in your query. Everything
3867 which is put into the <i>value</i> input box on the query box page will
3868 replace the string &quot;/*[VARIABLE]*/&quot; in your stored query. Just be
3869 aware of that you HAVE to create a valid query, otherwise your query won't be
3870 even able to be stored in the database.<br />
3871 Also remember, that everything else inside the <b>/*[VARIABLE]*/</b> string
3872 for your query will remain the way it is, but will be stripped of the /**/
3873 chars. So you can use:<br /><br />
3875 <code>/*, [VARIABLE] AS myname */</code><br /><br />
3877 which will be expanded to<br /><br />
3879 <code>, VARIABLE as myname</code><br /><br />
3881 in your query, where VARIABLE is the string you entered in the input box. If
3882 an empty string is provided, no replacements are made.<br /><br />
3884 A more complex example. Say you have stored this query:<br /><br />
3885 <code>SELECT Name, Address FROM addresses WHERE 1 /* AND Name LIKE '%[VARIABLE]%' */</code>
3886 <br /><br />
3888 Say, you now enter &quot;phpMyAdmin&quot; as the variable for the stored query,
3889 the full query will be:<br /><br />
3891 <code>SELECT Name, Address FROM addresses WHERE 1 AND Name LIKE '%phpMyAdmin%'</code>
3892 <br /><br />
3894 You can use multiple occurrences of <b>/*[VARIABLE]*/</b> in a single query.<br />
3895 <b>NOTE THE ABSENCE OF SPACES</b> inside the &quot;/**/&quot; construct. Any
3896 spaces inserted there
3897 will be later also inserted as spaces in your query and may lead to unexpected
3898 results especially when
3899 using the variable expansion inside of a &quot;LIKE ''&quot; expression.<br />
3900 Your initial query which is going to be stored as a bookmark has to yield at
3901 least one result row so
3902 you can store the bookmark. You may have that to work around using well
3903 positioned &quot;/**/&quot; comments.</p>

3943 You will see two lists of values, the first list containing the key
3944 and the display field, the second list containing the display field
3945 and the key. The reason for this is to be able to type the first
3946 letter of either the key or the display field.<br /><br />

4072 <!-- DEVELOPERS -->
4073 <h2 id="developers">Developers Information</h2>
4075 <p> phpMyAdmin is Open Source, so you're invited to contribute to it. Many
4076 great features have been written by other people and you too can help to
4077 make phpMyAdmin a useful tool.</p>
4079 <p> If you're planning to contribute source, please read the following
4080 information:</p>
4082 <ul><li>All files include <i>libraries/header.inc.php</i> (layout),.
4083 <i>libraries/common.lib.php</i> (common functions) and
4084 <i>config.inc.php</i>.<br />
4085 Only configuration data should go in <i>config.inc.php</i>. Please keep
4086 it free from other code.<br />
4087 Commonly used functions should be added to
4088 <i>libraries/common.lib.php</i> and more specific ones may be added
4089 within a library stored into the <i>libraries</i> sub-directory.</li>
4090 <li>Obviously, you're free to use whatever coding style you want. But
4091 please try to keep your code as simple as possible: beginners are
4092 using phpMyAdmin as an example application.<br />
4093 As far as possible, we want the scripts to be XHTML1.0 and CSS2
4094 compliant on one hand, they fit the
4095 <a href="http://pear.php.net/">
4096 <abbr title="PHP Extension and Application Repository">PEAR</abbr>
4097 coding standards</a>
4098 on the other hand. Please pay attention to this.</li>
4099 <li>Please try to keep up the file-naming conventions. Table-related stuff
4100 goes to <i>tbl_*.php</i>, db-related code to <i>db_*.php</i>,
4101 server-related tools to <i>server_*.php</i> and so on.</li>
4102 <li>Please don't use verbose strings in your code, instead add the string
4103 (at least) to <i>english-iso-8859-1.inc.php</i> and print() it out.</li>
4104 <li>If you want to be really helpful, write an entry for the ChangeLog.</li>
4105 <li id="developersdbg">
4106 The DBG extension (<a href="http://dd.cron.ru/dbg/">PHP
4107 Debugger DBG</a>) is now supported by phpMyAdmin for developers to
4108 better debug and profile their code.<br />
4109 Please see the
4110 <a href="#cfg_DBG" class="configrule">$cfg['DBG']*</a> configuration
4111 options for more information.<br />
4112 This is in memoriam of the Space Shuttle Columbia (STS-107) which was
4113 lost during its re-entry into Earth's atmosphere and in memory of the
4114 brave men and women who gave their lives for the people of Earth.</li>

4284 Original Credits of Version 2.1.0
4285 ---------------------------------
4287 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4288 to create a web-based interface to MySQL using PHP3. Although I have not
4289 used any of his source-code, there are some concepts I've borrowed from
4290 him. phpMyAdmin was created because Peter told me he wasn't going to
4291 further develop his (great) tool.
4292 Thanks go to
4293 - Amalesh Kempf &lt;ak-lsml_at_living-source.com&gt; who contributed the
4294 code for the check when dropping a table or database. He also suggested
4295 that you should be able to specify the primary key on tbl_create.php3. To
4296 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4297 well as a bug-report. Plus many smaller improvements.
4298 - Jan Legenhausen &lt;jan_at_nrw.net&gt;: He made many of the changes that
4299 were introduced in 1.3.0 (including quite significant ones like the
4300 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4301 bug-fixes and help.
4302 - Marc Delisle &lt;DelislMa_at_CollegeSherbrooke.qc.ca&gt; made phpMyAdmin
4303 language-independent by outsourcing the strings to a separate file. He
4304 also contributed the French translation.
4305 - Alexandr Bravo &lt;abravo_at_hq.admiral.ru&gt; who contributed
4306 tbl_select.php3, a feature to display only some fields from a table.
4307 - Chris Jackson &lt;chrisj_at_ctel.net&gt; added support for MySQL
4308 functions in tbl_change.php3. He also added the
4309 &quot;Query by Example&quot; feature in 2.0.
4310 - Dave Walton &lt;walton_at_nordicdms.com&gt; added support for multiple
4311 servers and is a regular contributor for bug-fixes.
4312 - Gabriel Ash &lt;ga244_at_is8.nyu.edu&gt; contributed the random access
4313 features for 2.0.6.
4314 The following people have contributed minor changes, enhancements, bugfixes
4315 or support for a new language:
4316 Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
4317 Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov,
4318 Sascha Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns,
4319 G. Wieggers.
4321 And thanks to everyone else who sent me email with suggestions, bug-reports
4322 and or just some feedback.
