version.php

This file is included in the main directory of plugin. It is compulsory for the most of plugin types. Even when not compulsory it is highly recommended.

It contains a number of fields, which are used during the install / upgrade process to make sure the plugin is compatible with the current Moodle install, as well as spotting whether an upgrade is needed.

The file is a standard PHP file, starting with an opening '<?php' tag and defining the following variables:

Note! For Activity modules replace $plugin-> with $module-> in the following example!

• $plugin->version = 2011051000;
  • Required - the version number of your plugin in the form YYYYMMDDxx, so this example is 10th May 2011 (with 00 indicating this is the first version for that day)
• $plugin->requires = 2010112400;
  • Optional - minimum version number of Moodle that this plugin requires (Moodle 1.9 = 2007101509; Moodle 2.0 = 2010112400; Moodle 2.1 = 2011070100)
• $plugin->cron = 0;
  • Optional - time interval (in seconds) between calls to the plugin's 'cron' function; set to 0 to disable the cron function calls.
  • Cron support is not yet implemented for all plugins.
• $plugin->component = 'plugintype_pluginname';
  • Optional - frankenstyle plugin name, strongly recommended. It is used for installation and upgrade diagnostics.
• $plugin->maturity = MATURITY_STABLE;
  • Optional - how stable the plugin is: MATURITY_ALPHA, MATURITY_BETA, MATURITY_RC, MATURITY_STABLE
• $plugin->release = '2.x (Build: 2011051000)';
  • Optional - Human-readable version name
• $plugin->dependencies = array ('mod_forum' => ANY_VERSION, 'mod_data' => 2010020300);
  • Optional - list of other plugins that are required for this plugin to work (Moodle 2.2 and above)
  • In this example, the plugin requires any version of the forum activity and version '20100020300' (or above) of the database activity
