The M in Moodle stands for modular. The easiest and most maintainable way to add new functionality to Moodle is by writing one of these types of plugin.

Obtaining the list of plugin types known to your Moodle

To get the most exact list of types in your version of Moodle, use the following script. Put it to a file in the root directory of your Moodle installation and execute it via command line.

define('CLI_SCRIPT', true);

$pluginman = core_plugin_manager::instance();

foreach ($pluginman->get_plugin_types() as $type => $dir) {
    $dir = substr($dir, strlen($CFG->dirroot));
    printf("%-20s %-50s %s".PHP_EOL, $type, $pluginman->plugintype_name_plural($type), $dir);

Things you can find in all plugins

Although there are many different types of plugin, there are some things that work the same way in all plugin types. Please see Plugin files page that describes things that work the same in all plugin types.

Naming conventions

Warning if you have to choose a plugin (directory) name. The name is validated by the method lib/classes/component.php::is_valid_plugin_name() with a regexp: /^[a-z](?:[a-z0-9_](?!__))*[a-z0-9]+$/. In particular, the minus (-) character is not considered as valid, and the plugin will be silently ignored if the name is not valid.

There is an exception for activity modules that can not have the underscore in their name for legacy reasons.
