ezinfo.php: what the About page reads #

Every theme extension tells the system who it is in two small files: ezinfo.php and extension.xml. This page is about the first. When you finish it you have an ezinfo.php that shows your theme's name, version, license and website on Setup > About (/ezinfo/about) and on Setup > Extensions.

Before you start #

• You have a theme extension folder, for example extension/mytheme/ (The folder structure of a theme extension).
• You know the version you are about to release (Choosing a version number).

Step by step #

1. Create extension/mytheme/ezinfo.php. The class name is the folder name followed by Info, and info() is static:

   <?php
   class mythemeInfo
   {
       public static function info()
       {
           return array(
               'Name'      => "My Theme",
               'Version'   => "1.0.0",
               'Copyright' => "Copyright (C) 2026 Your Name",
               'License'   => "GNU General Public License v2.0 (or any later version)",
               'Info_url'  => "https://github.com/<you>/mytheme",
           );
       }
   }

2. Fill each key:

   Key	What to write	Example from a real theme
   Name	The human name of the theme	CJW Themes Jumper
   Version	The release version, without a v (tag v0.1.6 gives 0.1.6)	0.1.6
   Copyright	The years and every holder whose work is in the theme	2007 - 2026 CJW Network, JAC Systeme GmbH and 7x
   License	Exactly what your LICENSE file says	GNU General Public License v2.0 (or any later version)
   Info_url	The theme's project page, usually its repository	https://github.com/se7enxweb/cjw_themes_jumper
   Author (optional)	Who wrote it	7x

   The examples are copied from extension/cjw_themes_jumper/ezinfo.php as it ships with release 0.1.6.

3. Write the same version, license and website into extension.xml. The About page reads extension.xml first when it has a <metadata> block, so the two files must agree (Keeping every version field in sync).

4. Check the file:

   php -l extension/mytheme/ezinfo.php

   Expected: No syntax errors detected in extension/mytheme/ezinfo.php.

5. Open Setup > About in the administration. Your theme's row shows the name, version, license and website you wrote. A dash means the value is missing.

Rules worth keeping #

• Quote every key ('Version', not Version) and keep info() static.
• Never write a placeholder such as //autogentag// or dev-master as the version. The About page and the upgrade check cannot tell a placeholder from a real release.
• Raise the version in the commit the release tag points at, never after the tag (Bumping the version before the tag).
• The license line must match the LICENSE file. If the theme is GPL, write the license's full name as above.
