81 <!-- INTRODUCTION -->
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.

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>
147 <!-- INSTALLATION -->
155 </ol>
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
161 be used for this.
162 </p>
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
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
182 </li>
183 <li>Untar or unzip the distribution (be sure to unzip the subdirectories):
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
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
198 provided for those who prefer a graphical installation. Creating a
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
204 file) in the main (top-level) phpMyAdmin directory (the one
208 default value is okay for a particular setting, there is no
210 few directives to get going, a simple configuration may look
211 like this:
212 <pre>
213 <?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 ?>
220 </pre>
221 Or, if you prefer to not be prompted every time you log in:
222 <pre>
223 <?php
225 $i=0;
226 $i++;
227 $cfg['Servers'][$i]['user'] = 'root';
228 $cfg['Servers'][$i]['password'] = 'cbb74bc'; // use here your password
229 ?>
230 </pre>
231 For a full explanation of possible configuration values, see the
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
258 the webserver does not have the proper permissions you may see the
260 config/</tt> directory exists and has the proper permissions -
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 </pre>
271 Now the file is ready to be used. You can choose to review or edit
272 the file with your favorite editor, if you prefer to set some
273 advanced options which the setup script does not provide.</li></ul></li>
274 <li>If you are using the
276 protect the phpMyAdmin installation directory because using
277 config does not require a user to
278 enter a password to access the phpMyAdmin installation. Use of an alternate
279 authentication method is recommended, for example with
287 in your browser. phpMyAdmin should now display a welcome screen
288 and your databases, or a login dialog if using
290 authentication mode.</li>
292 webserver configuration. For Apache you can use supplied .htaccess file
293 in that folder, for other webservers, you should configure this yourself.
294 Such configuration prevents from possible path exposure and cross side
295 scripting vulnerabilities that might happen to be found in that code.</li>
296 </ol>
300 <p> For a whole set of new features (bookmarks, comments,
303 transformation, etc.) you need to create a set of special tables. Those
304 tables can be located in your own database, or in a central database for a
305 multi-user installation (this database would then be accessed by the
306 controluser, so no other user should have rights to it).</p>
315 installation.</p>
320 <p> You can use your phpMyAdmin to create the tables for you. Please be aware
321 that you may need special (administrator) privileges to create the database
322 and tables, and that the script may need some tuning, depending on the
323 database name.</p>
328 section</a>. You will also need to have a controluser with the proper rights
335 unpacked one. Configuration files from very old versions (2.3.0 or before) may
336 require some tweaking as some options have been changed or removed.
338 statement that you might find near the end of your configuration file.</p>
342 is version-specific.</p>
345 version 4.1.2 or newer and if you use the pmadb/linked table infrastructure,
346 you should run the SQL script found in
353 where you want to give users access to their own database and don't want
354 them to play around with others.<br />
355 Nevertheless be aware that MS Internet Explorer seems to be really buggy
357 in this area!<br />
360 that your user/password pair are not in clear in the configuration file.
361 </li>
364 authentication modes are more secure: the MySQL login information does
365 not need to be set in the phpMyAdmin configuration file (except possibly
367 However, keep in mind that the password travels in plain text, unless
368 you are using the HTTPS protocol.<br />
369 In cookie mode, the password is stored, encrypted with the blowfish
370 algorithm, in a temporary cookie.</li>

428 Of course, the above queries only work if your MySQL version supports
432 on a set of particular databases. Normally you shouldn't give global

2080 <!-- TRANSFORMATIONS -->
2086 </ol>
2090 <p> To enable transformations, you have to setup the <tt>column_info</tt> table
2092 section</a> on how to do so.</p>
2094 <p> You can apply different transformations to the contents of each field. The
2095 transformation will take the content of each field and transform it with
2096 certain rules defined in the selected transformation.</p>
2098 <p> Say you have a field 'filename' which contains a filename. Normally you would
2099 see in phpMyAdmin only this filename. Using transformations you can transform
2100 that filename into a HTML link, so you can click inside of the phpMyAdmin
2101 structure on the field's link and will see the file displayed in a new browser
2102 window. Using transformation options you can also specify strings to
2103 append/prepend to a string or the format you want the output stored in.</p>
2105 <p> For a general overview of all available transformations and their options,
2106 you can consult your
2107 <i><www.your-host.com>/<your-install-dir>/transformation_overview.php</i>
2108 installation.</p>
2110 <p> For a tutorial on how to effectively use transformations, see our
2112 the official phpMyAdmin homepage.</p>
2116 <p> Go to your <i>tbl_structure.php</i> page (i.e. reached through
2117 clicking on the 'Structure' link for a table). There click on
2118 "Change" (or change icon) and there you will see three new fields at
2119 the end of the line. They are called 'MIME-type', 'Browser transformation' and
2120 'Transformation options'.</p>
2122 <ul><li>The field 'MIME-type' is a drop-down field. Select the MIME-type
2123 that corresponds to the column's contents. Please note that
2124 transformations are inactive as long as no MIME-type is selected.</li>
2126 <li>The field 'Browser transformation' is a drop-down field. You can choose from a
2127 hopefully growing amount of pre-defined transformations. See below for information on
2128 how to build your own transformation.<br />
2130 There are global transformations and mimetype-bound transformations. Global transformations
2131 can be used for any mimetype. They will take the mimetype, if necessary, into regard.
2132 Mimetype-bound transformations usually only operate on a certain mimetype. There are
2133 transformations which operate on the main mimetype (like 'image'), which will most likely
2134 take the subtype into regard, and those who only operate on a
2135 specific subtype (like 'image/jpeg').<br />
2137 You can use transformations on mimetypes for which the function was not defined for. There
2138 is no security check for you selected the right transformation, so take care of what the
2139 output will be like.</li>
2141 <li>The field 'Transformation options' is a free-type textfield. You have to enter
2142 transform-function specific options here. Usually the transforms can operate with default
2143 options, but it is generally a good idea to look up the overview to see which options are
2144 necessary.<br />
2146 Much like the ENUM/SET-Fields, you have to split up several options using the format
2147 'a','b','c',...(NOTE THE MISSING BLANKS). This is because internally the options will be
2148 parsed as an array, leaving the first value the first element in the array, and so
2149 forth.<br />
2151 If you want to specify a MIME character set you can define it in the transformation_options.
2152 You have to put that outside of the pre-defined options of the specific mime-transform,
2154 for which you can specify 2 options and you want to append a character set, enter "'first
2155 parameter','second parameter','charset=us-ascii'". You can, however use the defaults for
2157 </ul>
2161 <p> All mimetypes and their transformations are defined through single files in
2162 the directory 'libraries/transformations/'.</p>
2164 <p> They are stored in files to ease up customization and easy adding of new
2165 transformations.</p>
2167 <p> Because the user cannot enter own mimetypes, it is kept sure that transformations
2168 always work. It makes no sense to apply a transformation to a mimetype, the
2169 transform-function doesn't know to handle.</p>
2171 <p> One can, however, use empty mime-types and global transformations which should work
2172 for many mimetypes. You can also use transforms on a different mimetype they where built
2173 for, but pay attention to option usage as well as what the transformation does to your
2174 field.</p>
2176 <p> There is a basic file called '<i>global.inc.php</i>'. This function can be included by
2177 any other transform function and provides some basic functions.</p>
2179 <p> There are 5 possible file names:</p>
2181 <ol><li>A mimetype+subtype transform:<br /><br />
2183 <tt>[mimetype]_[subtype]__[transform].inc.php</tt><br /><br />
2185 Please not that mimetype and subtype are separated via '_', which shall
2186 not be contained in their names. The transform function/filename may
2187 contain only characters which cause no problems in the file system as
2188 well as the PHP function naming convention.<br /><br />
2190 The transform function will the be called
2191 '<tt>PMA_transform_[mimetype]_[subtype]__[transform]()</tt>'.<br /><br />
2193 <b>Example:</b><br /><br />
2195 <tt>text_html__formatted.inc.php</tt><br />
2196 <tt>PMA_transform_text_html__formatted()</tt></li>
2198 <li>A mimetype (w/o subtype) transform:<br /><br />
2200 <tt>[mimetype]__[transform].inc.php</tt><br /><br />
2202 Please note that there are no single '_' characters.
2203 The transform function/filename may contain only characters which cause
2204 no problems in the file system as well as the PHP function naming
2205 convention.<br /><br />
2207 The transform function will the be called
2208 '<tt>PMA_transform_[mimetype]__[transform]()</tt>'.<br /><br />
2210 <b>Example:</b><br /><br />
2212 <tt>text__formatted.inc.php</tt><br />
2213 <tt>PMA_transform_text__formatted()</tt></li>
2215 <li>A mimetype+subtype without specific transform function<br /><br />
2217 <tt>[mimetype]_[subtype].inc.php</tt><br /><br />
2219 Please note that there are no '__' characters in the filename. Do not
2220 use special characters in the filename causing problems with the file
2221 system.<br /><br />
2223 No transformation function is defined in the file itself.<br /><br />
2225 <b>Example:</b><br /><br />
2227 <tt>text_plain.inc.php</tt><br />
2228 (No function)</li>
2230 <li>A mimetype (w/o subtype) without specific transform function<br /><br />
2232 <tt>[mimetype].inc.php</tt><br /><br />
2234 Please note that there are no '_' characters in the filename. Do not use
2235 special characters in the filename causing problems with the file system.
2236 <br /><br />
2238 No transformation function is defined in the file itself.<br /><br />
2240 <b>Example:</b><br /><br />
2242 <tt>text.inc.php</tt><br />
2243 (No function)</li>
2245 <li>A global transform function with no specific mimetype<br /><br />
2247 <tt>global__[transform].inc.php</tt><br /><br />
2249 The transform function will the be called
2250 '<tt>PMA_transform_global__[transform]()</tt>'.<br /><br />
2252 <b>Example:</b><br /><br />
2254 <tt>global__formatted</tt><br />
2255 <tt>PMA_transform_global__formatted()</tt></li>
2256 </ol>
2258 <p> So generally use '_' to split up mimetype and subtype, and '__' to provide a
2259 transform function.</p>
2261 <p> All filenames containing no '__' in themselves are not shown as valid transform
2262 functions in the dropdown.</p>
2264 <p> Please see the libraries/transformations/TEMPLATE file for adding your own transform
2265 function. See the libraries/transformations/TEMPLATE_MIMETYPE for adding a mimetype
2266 without a transform function. Also note the introduction of a function description in
2267 the language files. For each function a $strTransformation_[filename without .inc.php]
2268 has to exist.</p>
2270 <p> You can use the template generator to generate new functions and entries in the
2271 language file.</p>
2273 <p> To create a new transform function please see
2274 <tt>libraries/transformations/template_generator.sh</tt>.
2275 To create a new, empty mimetype please see
2276 <tt>libraries/transformations/template_generator_mimetype.sh</tt>.</p>
2278 <p> A transform function always gets passed three variables:</p>
2280 <ol><li><b>$buffer</b> - Contains the text inside of the column. This is the text,
2281 you want to transform.</li>
2282 <li><b>$options</b> - Contains any user-passed options to a transform function
2283 as an array.</li>
2284 <li><b>$meta</b> - Contains an object with field information to your column.
2285 The data is drawn from the output of the
2287 function. This means, all object properties described on the
2289 available in this variable and can be used to transform a field accordingly
2290 to unsigned/zerofill/not_null/... properties.<br />
2291 The $meta->mimetype variable contains the original MIME-type of the
2292 field (i.e. 'text/plain', 'image/jpeg' etc.)</li>
2293 </ol>

2403 We recommend the following setup for Apache servers running in safe mode,
2404 to enable uploads of files while being reasonably secure:</p>
2406 <ul><li>create a separate directory for uploads: <tt>mkdir /tmp/php</tt></li>
2407 <li>give ownership to the Apache server's user.group:

2449 <p> Since version 2.2.4, phpMyAdmin supports servers with open_basedir

2453 owner as the owner of your phpMyAdmin directory. The uploaded files will

2485 were named <tt>user</tt> and <tt>password</tt>. Please modify your field
2486 names to align with current standards.</p>
2491 </h4>
2493 <p> Starting with version 2.7.0, the import engine has been re–written and these
2494 problems should not occur. If possible, upgrade your phpMyAdmin to the latest version
2495 to take advantage of the new import features.</p>
2497 <p> The first things to check (or ask your host provider to check) are the
2498 values of <tt>upload_max_filesize</tt>, <tt>memory_limit</tt> and
2499 <tt>post_max_size</tt> in the <i>php.ini</i> configuration file.
2500 All of these three settings limit the maximum size of data that can be
2501 submitted and handled by PHP. One user also said that post_max_size
2502 and memory_limit need to be larger than upload_max_filesize.<br /> <br />
2504 There exist several workarounds if your upload is too big or your
2505 hosting provider is unwilling to change the settings:</p>
2508 feature. This allows one to

2515 or any third party applications, but are aware of users having success
2516 with it.</li>
2517 <li>If you have shell (command line) access, use MySQL to import the files
2518 directly. You can do this by issuing the "source" command from
2519 within MySQL: <tt>source <i>filename.sql</i></tt>.</li>
2520 </ul>

2526 <p> All MySQL versions from 3.23.32 till 5.0 (except for 4.1.0 and 4.1.1) are

2533 Either way, the developers of both extensions recommend to use the classic
2534 extension for MySQL 4.0 and below and MySQLi for MySQL 4.1 and newer.<br />
2535 When compiling php, we strongly recommend that you manually link the MySQL
2536 extension of your choice to a MySQL client library of at least the same
2537 minor version since the one that is bundled with some php distributions is

2592 <p> To connect to a MySQL server, PHP needs a set of MySQL functions called
2593 "MySQL extension". This extension may be part of the PHP
2594 distribution (compiled-in), otherwise it needs to be loaded dynamically. Its
2595 name is probably <i>mysql.so</i> or <i>php_mysql.dll</i>. phpMyAdmin tried
2596 to load the extension but failed.<br /><br />
2598 Usually, the problem is solved by installing a software package called
2599 "PHP-MySQL" or something similar.</p>

2619 <p> This happens because the MySQL directive <tt>lower_case_table_names</tt>
2620 defaults to 1 (<tt>ON</tt>) in the Win32 version of MySQL. You can change
2621 this behavior by simply changing the directive to 0 (<tt>OFF</tt>):<br />
2622 Just edit your <tt>my.ini</tt> file that should be located in your Windows
2623 directory and add the following line to the group [mysqld]:</p>
2625 <pre>set-variable = lower_case_table_names=0</pre>
2627 <p> Next, save the file and restart the MySQL service. You can always check the
2628 value of this directive using the query</p>

2650 </pre>
2652 <p> as this version of mod_gzip on Apache (Windows) has problems handling
2653 PHP scripts. Of course you have to restart Apache.</p>
2658 I get the error "No input file specified" when trying to
2659 run phpMyAdmin.</a></h4>
2661 <p> This is a permission problem. Right-click on the phpmyadmin folder
2662 and choose properties. Under the tab Security, click on "Add"
2663 and select the user "IUSR_machine" from the list. Now set his
2664 permissions and it should work.</p>

2674 PHP 5.0.0.</p>
2678 message 'Errorcode: 13'. What does this mean?</a></h4>
2680 <p> This can happen due to a MySQL bug when having database / table names with
2681 upper case characters although <tt>lower_case_table_names</tt> is set to 1.
2682 To fix this, turn off this directive, convert all database and table names
2683 to lower case and turn it on again. Alternatively, there's a bug-fix
2684 available starting with MySQL 3.23.56 / 4.0.11-gamma.</p>
2688 and the fields are duplicated.</a></h4>
2690 <p> It is possible to configure Apache in such a way that PHP has problems
2691 interpreting .php files.</p>
2693 <p> The problems occur when two different (and conflicting) set of directives
2694 are used:</p>
2696 <pre>
2697 SetOutputFilter PHP
2698 SetInputFilter PHP
2699 </pre>
2701 <p> and</p>
2703 <pre>AddType application/x-httpd-php .php</pre>
2705 <p> In the case we saw, one set of directives was in
2706 <tt>/etc/httpd/conf/httpd.conf</tt>, while
2707 the other set was in <tt>/etc/httpd/conf/addon-modules/php.conf</tt>.<br />
2708 The recommended way is with <tt>AddType</tt>, so just comment out
2709 the first set of lines and restart Apache:</p>
2711 <pre>
2712 #SetOutputFilter PHP
2713 #SetInputFilter PHP
2714 </pre>
2719 <p> This problem is known to happen when the server is running Turck MMCache
2720 but upgrading MMCache to version 2.3.21 solves the problem.</p>
2725 <p> Yes.<br />
2726 However, phpMyAdmin needs to be backwards compatible to php4. This is why
2727 phpMyAdmin disables the <tt>E_STRICT</tt> error_level in
2728 <tt>error_reporting</tt> settings.

2801 password encryption in cookie auth doesn't work.</a></h4>
2803 <p> If your cluster consist of different architectures, PHP code used for
2804 encryption/decryption won't work correct. This is caused by use of
2805 pack/unpack functions in code. Only solution is to use mcrypt extension
2806 which works fine in this case.</p>
2811 <p> Yes but the default configuration values of Suhosin are known to cause
2812 problems with some operations, for example editing a table with many
2813 columns and no primary key. Tuning information is available at

2825 headers already sent by ..." is displayed, what's the problem?</a></h4>
2827 <p> Edit your <i>config.inc.php</i> file and ensure there is nothing
2828 (I.E. no blank lines, no spaces, no characters...) neither before the
2829 <tt><?php</tt> tag at the beginning, neither after the <tt>?></tt>
2830 tag at the end. We also got a report from a user under IIS, that used
2831 a zipped distribution kit: the file <tt>libraries/Config.class.php</tt>
2832 contained an end-of-line character (hex 0A) at the end; removing this character
2833 cleared his errors.</p>
2838 <p> Either there is an error with your PHP setup or your username/password is
2839 wrong. Try to make a small script which uses mysql_connect and see if it
2840 works. If it doesn't, it may be you haven't even compiled MySQL support
2841 into PHP.</p>
2845 connect to local MySQL server through socket '/tmp/mysql.sock'
2846 (111) ..." is displayed. What can I do?</a></h4>
2848 <p> For RedHat users, Harald Legner suggests this on the mailing list:</p>
2850 <p> On my RedHat-Box the socket of MySQL is <i>/var/lib/mysql/mysql.sock</i>.
2851 In your <i>php.ini</i> you will find a line</p>
2853 <pre>mysql.default_socket = /tmp/mysql.sock</pre>
2855 <p> change it to</p>
2857 <pre>mysql.default_socket = /var/lib/mysql/mysql.sock</pre>
2859 <p> Then restart apache and it will work.</p>
2861 <p> Here is a fix suggested by Brad Ummer:</p>
2863 <ul><li>First, you need to determine what socket is being used by MySQL.<br />
2864 To do this, telnet to your server and go to the MySQL bin directory. In
2865 this directory there should be a file named <i>mysqladmin</i>. Type
2866 <tt>./mysqladmin variables</tt>, and this should give you a bunch of
2867 info about your MySQL server, including the socket
2868 (<i>/tmp/mysql.sock</i>, for example).</li>
2869 <li>Then, you need to tell PHP to use this socket.<br /> To do this in
2870 phpMyAdmin, you need to complete the socket information in the
2871 <i>config.inc.php</i>.<br />
2872 For example:
2874 $cfg['Servers'][$i]['socket'] = '/tmp/mysql.sock';</a>
2875 <br /><br />
2877 Please also make sure that the permissions of this file allow to be readable
2878 by your webserver (i.e. '0755').</li>
2879 </ul>
2881 <p> Have also a look at the
2883 corresponding section of the MySQL documentation</a>.</p>
2887 what can I do?</a></h4>
2890 directive to <tt>FALSE</tt> in the phpMyAdmin configuration file. It helps
2891 sometime.<br />
2892 Also have a look at your PHP version number: if it contains "4.0b..."
2893 it means you're running a beta version of PHP. That's not a so good idea,
2894 please upgrade to a plain revision.</p>
2898 or a table, an error 404 (page not found) is displayed or, with <abbr title="HyperText Transfer Protocol">HTTP</abbr> or
2899 cookie authentication, I'm asked to log in again. What's wrong?</a></h4>
2901 <p> Check the value you set for the
2903 directive in the phpMyAdmin configuration file.</p>
2907 password: YES)"-error when trying to access a MySQL-Server on a
2908 host which is port-forwarded for my localhost.</a></h4>
2910 <p> When you are using a port on your localhost, which you redirect via
2911 port-forwarding to another host, MySQL is not resolving the localhost
2912 as expected.<br />
2913 Erik Wasser explains: The solution is: if your host is "localhost"
2914 MySQL (the commandline tool 'mysql' as well) always tries to use the socket
2915 connection for speeding up things. And that doesn't work in this configuration
2916 with port forwarding.<br />
2922 <p> Themes are configured with
2926 <br />
2928 should not delete the directory "original" or its underlying
2929 structure, because this is the system theme used by phpMyAdmin.
2930 "original" contains all images and styles, for backwards
2931 compatibility and for all themes that would not include images or css-files.
2932 <br /><br />
2935 is enabled, you can select your favorite theme on the main page. Your
2936 selected theme will be stored in a cookie.<br /><br /></p>
2938 <p> To create a theme:</p>
2940 <ul><li>make a new subdirectory (for example "your_theme_name") under
2942 (by default <tt>themes</tt>)</li>
2943 <li>copy the files and directories from "original" to
2944 "your_theme_name"</li>
2945 <li>edit the css-files in "your_theme_name/css"</li>
2946 <li>put your new images in "your_theme_name/img"</li>
2947 <li>edit <tt>layout.inc.php</tt> in "your_theme_name"</li>
2948 <li>edit <tt>info.inc.php</tt> in "your_theme_name" to
2949 contain your chosen theme name, that will be visible in user interface</li>
2950 <li>make a new screenshot of your theme and save it under
2951 "your_theme_name/screen.png"</li>
2952 </ul>
2954 <p> In theme directory there is file <tt>info.inc.php</tt> which contains
2955 theme verbose name, theme generation and theme version. These versions and
2956 generations are enumerated from 1 and do not have any direct dependence on
2957 phpMyAdmin version. Themes within same generation should be backwards
2958 compatible - theme with version 2 should work in phpMyAdmin requiring
2959 version 1. Themes with different generation are incompatible.</p>
2961 <p> If you do not want to use your own symbols and buttons, remove the
2962 directory "img" in "your_theme_name". phpMyAdmin will
2963 use the default icons and buttons (from the system-theme "original").
2964 </p>
2968 what can I do?</a></h4>
2970 <p> Here are a few points to check:</p>
2972 <ul><li>In <tt>config.inc.php</tt>, try to leave the
2974 directive empty. See also
2976 </li>
2977 <li>Maybe you have a broken PHP installation or you need to upgrade
2978 your Zend Optimizer. See
2980 http://bugs.php.net/bug.php?id=31134</a>.
2981 </li>
2982 <li>If you are using Hardened PHP with the ini directive <tt>varfilter.max_request_variables</tt>
2983 set to the default (200) or another low value, you could get this
2984 error if your table has a high number of columns. Adjust this setting
2985 accordingly. (Thanks to Klaus Dorninger for the hint).
2986 </li>
2987 <li>In the <tt>php.ini</tt> directive <tt>arg_separator.input</tt>, a value
2988 of ";" will cause this error. Replace it with "&;".
2989 </li>
2991 you might want to increase
2993 </li>
2994 <li>The directory specified in the <tt>php.ini</tt> directive <tt>session.save_path</tt> does not exist or is read-only.
2995 </li>
2996 </ul>
3003 who logged out can not log in again in with the same nick.</a></h4>
3005 <p> This is related to the authentication mechanism (protocol) used by
3006 phpMyAdmin. To bypass this problem: just close all the opened
3007 browser windows and then go back to phpMyAdmin. You should be able to
3008 log in again.</p>
3012 limit error or a time limit error.</a></h4>
3014 <p> Compressed dumps are built in memory and because of this are limited to
3015 php's memory limit. For GZip/BZip2 exports this can be overcome since 2.5.4
3016 using
3018 (enabled by default). Zip exports can not be handled this way, so if you need
3019 Zip files for larger dump, you have to use another way.</p>
3023 or alter a table.</a></h4>
3025 <p> This seems to be a InnoDB bug (fixed in MySQL 3.23.50?).</p>
3029 bundled with the MySQL server distribution.</a></h4>
3031 <p> The problem is that older versions of mysqldump created invalid comments like this:</p>
3033 <pre>
3034 -- MySQL dump 8.22
3035 --
3036 -- Host: localhost Database: database
3037 ---------------------------------------------------------
3038 -- Server version 3.23.54
3039 </pre>
3041 <p> The invalid part of the code is the horizontal line made of dashes that
3042 appears once in every dump created with mysqldump. If you want to run your
3043 dump you have to turn it into valid MySQL. This means, you have to add a
3044 whitespace after the first two dashes of the line or add a # before it:
3045 <br />
3046 <code>
3047 -- -------------------------------------------------------<br />
3048 </code>
3049 or<br />
3050 <code>
3051 #---------------------------------------------------------
3052 </code>
3053 </p>
3060 <p> Please note that you should not use the separating string multiple times
3061 without any characters between them, or at the beginning/end of your table
3062 name. If you have to, think about using another TableSeparator or disabling
3063 that feature</p>

3071 LEFT JOIN from the foreign table.<br /><br/>
3072 </p>
3076 I get series of errors like "Warning: unable to parse url". How
3077 can this be fixed?</a></h4>
3078 <p>
3079 Your table neither have a primary key nor an unique one, so we must use a
3080 long expression to identify this row. This causes problems to parse_url
3081 function. The workaround is to create a primary or unique key.
3082 <br />
3083 </p>
3087 a MIME-Transformation onto!</a></h4>
3089 <p> Due to a surrounding form-container (for multi-row delete checkboxes), no
3090 nested forms can be put inside the table where phpMyAdmin displays the results.
3091 You can, however, use any form inside of a table if keep the parent
3092 form-container with the target to tbl_row_delete.php and just put your own
3093 input-elements inside. If you use a custom submit input field, the form will
3094 submit itself to the displaying page again, where you can validate the
3095 $HTTP_POST_VARS in a transformation.
3097 For a tutorial on how to effectively use transformations, see our
3099 on the official phpMyAdmin-homepage.</p>
3103 MySQL server</a></h4>
3105 <p> When MySQL is running in ANSI-compatibility mode, there are some major
3108 http://dev.mysql.com/doc/mysql/en/ANSI_mode.html</a>). Most important of all,
3109 the quote-character (") is interpreted as an identifier quote character and
3110 not as a string quote character, which makes many internal phpMyAdmin
3112 statements. There is no workaround to this behaviour. News to this item will
3113 be posted in Bug report

3123 <p> Please make sure that your table has a primary key, so that phpMyAdmin
3124 can use it for the Edit and Delete links.</p>
3129 <p> phpMyAdmin uses a quick method to get the row count, and this method
3130 only returns an approximate count in the case of InnoDB tables. See
3132 a way to modify those results, but
3133 this could have a serious impact on performance.</p>
3138 <p> The number of records in queries containing COUNT and GROUP BY is
3139 not correctly calculated. Also, sorting results of a query like
3144 containing an hyphen.
3145 </a></h4>
3146 <p>
3147 The tests I have made with current MySQL 4.1.11 API shows that the
3148 API does not accept this syntax for the USE command. Enclosing the
3149 db name with backquotes works. For further confusion, no backquotes
3150 are needed with command-line mysql.

3288 <p>
3289 We could reproduce this problem only under Win98/98SE. Testing under
3290 WinNT4 or Win2K, we could easily create more than 60 fields.

3292 A workaround is to create a smaller number of fields, then come back to
3293 your table properties and add the other fields.

3527 <p> Here is an example with the tables persons, towns and countries, all
3529 table, create it as explained in the configuration section. Then create the
3530 example tables:</p>
3532 <pre>
3533 CREATE TABLE REL_countries (
3534 country_code char(1) NOT NULL default '',
3535 description varchar(10) NOT NULL default '',
3536 PRIMARY KEY (country_code)
3537 ) TYPE=MyISAM;
3539 INSERT INTO REL_countries VALUES ('C', 'Canada');
3541 CREATE TABLE REL_persons (

3543 person_name varchar(32) NOT NULL default '',
3545 country_code char(1) NOT NULL default '',
3546 PRIMARY KEY (id)
3547 ) TYPE=MyISAM;
3549 INSERT INTO REL_persons VALUES (11, 'Marc', 'S', '');
3550 INSERT INTO REL_persons VALUES (15, 'Paul', 'S', 'C');
3552 CREATE TABLE REL_towns (
3554 description varchar(30) NOT NULL default '',
3555 PRIMARY KEY (town_code)
3556 ) TYPE=MyISAM;
3558 INSERT INTO REL_towns VALUES ('S', 'Sherbrooke');
3559 INSERT INTO REL_towns VALUES ('M', 'Montréal');
3560 </pre>
3566 <li>in Links, for "country_code" choose "REL_countries->country_code"</li>

3578 <li>In the fields row, choose persons.person_name and click the
3580 <li>Do the same for towns.description and countries.descriptions in the
3583 the correct joins have been generated</li>
3585 </ul>
3589 <p>
3590 Starting from the previous example, create the pma_table_info as explained
3591 in the configuration section, then browse your persons table,
3592 and move the mouse over a town code or country code.
3593 <br /><br />
3594 See also <a href="#faq6_21"><abbr title="Frequently Asked Questions">FAQ</abbr> 6.21</a> for an additional feature that "display field"
3595 enables: drop-down list of possible values.
3596 </p>
3599 <a href="#faqpdf">6.8 How can I produce a <abbr title="Portable Document Format">PDF</abbr> schema of my database?</a></h4>
3600 <p>
3603 <br /><br />
3604 Then you need to think about your schema layout. Which tables will go on
3605 which pages?
3606 </p>
3607 <ul>
3613 page and click Go. If you like, you
3615 linked tables onto the new page.</li>
3616 <li>Select the name of the new page (making sure the Edit radio button
3617 is selected) and click Go.</li>
3619 Coordinates are relative; your diagram will
3620 be automatically scaled to fit the page. When initially placing tables
3621 on the page, just pick any coordinates -- say, 50x50. After clicking
3623 position the element correctly.</li>
3625 first be sure to click the Save
3626 button beneath the list of tables and coordinates, to save any changes
3627 you made there. Then scroll all the way down, select the
3629 you want, and click Go.</li>
3630 <li>Internet Explorer for Windows may suggest an incorrect filename when
3635 browsers on Windows, do not have this problem.</li>
3636 </ul>
3640 columns!</a></h4>
3642 <p> No, it's MySQL that is doing
3648 underscores in the database name?</a></h4>
3650 <p> If you do not put a backslash before the underscore, this is a wildcard
3653 john2db ...<br /><br />
3655 If you put a backslash before the underscore, it means that the database
3656 name will have a real underscore.</p>
3660 statistics pages?</a></h4>
3671 if it already exists during the import. It does NOT drop the table after
3672 your export, it only affects the import file.</li>
3674 Otherwise, you may get an error if the table name exists but has a
3675 different structure.</li>
3677 (if any) will be included in backup.</li>
3679 field and table names formed with special characters are protected.</li>
3681 types set in the pmadb in the dump as
3683 </li>
3684 </ul>
3689 command, for better documentation (but resulting file is bigger).</li>
3691 once the INSERT verb and the table name.</li>
3694 </li>
3696 more info is provided in the
3698 but basically with this selected, invalid values are adjusted and
3699 inserted rather than causing the entire statement to fail.</li>
3700 </ul>
3704 in its name.</a></h4>
3707 is the normal way to reference a database and table name. Worse, MySQL
3708 will usually let you create a database with a dot, but then you cannot
3709 work with it, nor delete it.</p>
3722 for usage.<br />
3723 On a more recent pear version, I had problems with the state of Net_DIME
3724 being beta, so this single command
3726 needed modules.<br />
3727 If you use the Validator, you should be aware that any
3729 submit will be stored anonymously (database/table/column names,
3730 strings, numbers replaced with generic values). The Mimer
3733 We utilize it as free SOAP service.</p>
3737 it, but MySQL says "BLOB column '...' used in key specification without
3740 <p> The right way to do this, is to create the field without any indexes,
3742 dialog. On this page, you will be able to choose your BLOB field, and
3743 set a size to the index, which is the condition to create an index on
3744 a BLOB field.</p>
3748 editing fields?</a></h4>
3750 <p> You can use Ctrl+arrows (Option+Arrows in Safari) for moving on most pages
3751 with many editing fields (table structure changes, row editing, etc.)
3752 (must be enabled in configuration - see.
3754 You can also have a look at the directive
3756 ('vertical') and see if this eases up editing for you.</p>
3760 WTF is this feature then useful for?</a></h4>
3762 <p> Slow down :). Defining mimetypes is of no use, if you can't put transformations
3763 on them. Otherwise you could just put a comment on the field. Because entering
3764 your own mimetype will cause serious syntax checking issues and validation,
3765 this introduces a high-risk false-user-input situation. Instead you have to
3766 initialize mimetypes using functions or empty mimetype definitions.<br />
3767 Plus, you have a whole overview of available mimetypes. Who knows all those
3768 mimetypes by heart so he/she can enter it at will?</p>
3772 can't I see any bookmarks below the query box? What is this variable for?
3773 </a></h4>
3775 <p> Any query you have executed can be stored as a bookmark on the page where the
3776 results are displayed. You will find a button labeled 'Bookmark this query'
3777 just at the end of the page.<br />
3778 As soon as you have stored a bookmark, it is related to the database you run
3779 the query on. You can now access a bookmark dropdown on each page, the query
3780 box appears on for that database.<br /><br />
3782 Since phpMyAdmin 2.5.0 you are also able to store variables for the bookmarks.
3786 aware of that you HAVE to create a valid query, otherwise your query won't be
3787 even able to be stored in the database.<br />
3789 for your query will remain the way it is, but will be stripped of the /**/
3790 chars. So you can use:<br /><br />
3794 which will be expanded to<br /><br />
3798 in your query, where VARIABLE is the string you entered in the input box. If
3799 an empty string is provided, no replacements are made.<br /><br />
3801 A more complex example. Say you have stored this query:<br /><br />
3803 <br /><br />
3806 the full query will be:<br /><br />
3809 <br /><br />
3813 spaces inserted there
3814 will be later also inserted as spaces in your query and may lead to unexpected
3815 results especially when
3817 Your initial query which is going to be stored as a bookmark has to yield at
3818 least one result row so
3819 you can store the bookmark. You may have that to work around using well
3823 <a href="#faq6_19">6.19 How can I create simple L<sup>A</sup>T<sub><big>E</big></sub>X document to
3824 include exported table?</a></h4>
3826 <p> You can simply include table in your L<sup>A</sup>T<sub><big>E</big></sub>X documents, minimal sample
3827 document should look like following one (assuming you have table
3830 <pre>
3831 \documentclass{article} % or any class you want
3832 \usepackage{longtable} % for displaying table
3833 \begin{document} % start of document
3834 \include{table} % including exported table
3835 \end{document} % end of document
3836 </pre>
3840 access them.
3841 </a></h4>
3844 TEMPORARY TABLES, SHOW DATABASES, LOCK TABLES. Those privileges also
3845 enable users to see all the database names.
3848 So if your users do not need those privileges, you can remove them and their
3849 databases list will shorten.</p>
3853 possible values for a field, based on some foreign table?</a></h4>
3855 <p> You have to setup appropriate links between the tables, and also
3859 foreign table, a drop-down list of values will be available.
3860 You will see two lists of values, the first list containing the key
3861 and the display field, the second list containing the display field
3862 and the key. The reason for this is to be able to type the first
3863 letter of either the key or the display field.<br /><br />
3865 For 200 values or more, a distinct window will appear, to browse foreign
3866 key values and choose one.</p>
3870 automatically when entering Browse mode for a table?</a></h4>
3872 <p> Yes. If a bookmark has the same label as a table name, it will be executed.
3873 </p>
3877 Excel files, how can I enable that?</a></h4>
3879 <p> Current version does support direct export to Microsoft Excel and Word
3880 versions 2000 and newer. If you need export older versions, you can use
3882 which works out of the box or you can
3884 several problems, most important are limitation of cell content to 255
3885 chars and no support for charsets, so think carefully whether you want to
3886 enable this.</b>. For enabling this you need to set
3890 module Spreadsheet_Excel_Writer into php include path. The
3891 installation can be done by following command:</p>
3893 <pre>
3894 pear -d preferred_state=beta install -a Spreadsheet_Excel_Writer
3895 </pre>
3897 <p> First part of switches set we want to install beta version of that module
3898 (no stable version available yet) and then we tell pear we want to satisfy
3899 dependencies.</p>
3901 <p> If you are running in PHP safe mode, you will have to set
3904 modules are located, for example:</p>
3906 <pre>
3907 safe_mode_include_dir = /usr/local/lib/php
3908 </pre>
3912 <pre>
3913 cd phpMyAdmin
3914 mkdir tmp
3915 chmod o+rwx tmp
3916 </pre>
3920 what happens to my column comments stored in pmadb?</a></h4>
3922 <p> Automatic migration of a table's pmadb-style column comments to the native
3923 ones is done whenever you enter Structure page for this table.</p>
3930 <p> Our Bug Tracker is located at
3932 under the Bugs section.<br /><br />
3934 But please first discuss your bug with other users:<br />

3946 Please note that we try not to use HTML entities like &eacute; in
3947 the translations, since we define the right character set in the file.
3948 With HTML entities, the text on JavaScript messages would not
3949 display correctly.
3950 However there are some entities that need to be there, for quotes
3951 ,non-breakable spaces, ampersands, less than, greater than.<br />
3952 You can then put your translations, as a zip file to avoid losing special
3953 characters, on the sourceforge.net translation tracker.<br />

4196 ---------------------------------
4198 This work is based on Peter Kuppelwieser's MySQL-Webadmin. It was his idea
4199 to create a web-based interface to MySQL using PHP3. Although I have not
4200 used any of his source-code, there are some concepts I've borrowed from
4201 him. phpMyAdmin was created because Peter told me he wasn't going to
4202 further develop his (great) tool.
4203 Thanks go to
4205 code for the check when dropping a table or database. He also suggested
4206 that you should be able to specify the primary key on tbl_create.php3. To
4207 version 1.1.1 he contributed the ldi_*.php3-set (Import text-files) as
4208 well as a bug-report. Plus many smaller improvements.
4210 were introduced in 1.3.0 (including quite significant ones like the
4211 authentication). For 1.4.1 he enhanced the table-dump feature. Plus
4212 bug-fixes and help.
4214 language-independent by outsourcing the strings to a separate file. He
4215 also contributed the French translation.
4217 tbl_select.php3, a feature to display only some fields from a table.
4219 functions in tbl_change.php3. He also added the
4222 servers and is a regular contributor for bug-fixes.
4224 features for 2.0.6.
4225 The following people have contributed minor changes, enhancements, bugfixes
4226 or support for a new language:
4227 Jim Kraai, Jordi Bruguera, Miquel Obrador, Geert Lund, Thomas Kleemann,
4228 Alexander Leidinger, Kiko Albiol, Daniel C. Chao, Pavel Piankov,
4229 Sascha Kettler, Joe Pruett, Renato Lins, Mark Kronsbein, Jannis Hermanns,
4230 G. Wieggers.
