Previously known as Top menu and Totara menu.

Adding new menu items

Plugin developers can also add Totara menu options as follows:

First, define a class that extends \totara_core\totara\menu\item and put it in a file in "[your-module]/classes/menu/[your-menu-item].php".

For an example, see totara/core/classes/menu/myteam.php.

You are expected to implement the following methods:

protected function get_default_title() - Returns a string to be used from the menu item name if not customised.
protected function get_default_url() - Returns a string containing the URL to point to (absolute or relative to wwwroot if it starts with a slash).

You can choose to implement the following methods:

public function get_default_visibility() - Returns a menu visibility constant to set the visibility when first added. Default is menu::SHOW_WHEN_REQUIRED.
public function get_default_sortorder() - Returns an integer to indicate default location within the menu when first added. Default is add to the end.
protected function check_visibility() - Returns either menu::SHOW_ALWAYS or menu::HIDE_ALWAYS. Called if visibility is set to menu::SHOW_WHEN_REQUIRED. Defaults to menu::SHOW_ALWAYS.
protected function get_default_parent() - Returns the class name of another menu item to use as the parent. Defaults to 'root' meaning top level.

Add a new file [your-module]/db/totaramenu.php with the following:

defined('MOODLE_INTERNAL') || die();
$TOTARAMENU->add([name of your autoloaded menu class]);

See totara/core/totaramenu.php for an example.

Bump the version of your module to trigger a database upgrade. The new menu item will be detected and automatically added to the menu.

Cache invalidation

The main menu structure is cached in user session for a certain period. If an admin setting affects availability of menu item then developer should add 'totara_menu_reset_all_caches' as setting update callback.

The cache timeout in a session is designed to accommodate changes in users permissions and audiences membership.
