Notifications

Users can register for notifications on activity by their friends or in their groups. The core provides e-mail-based notifications and the messages plugin adds site-based private messaging notifications. Additional types of notifications can be added through plugins.

A plugin registers with Elgg to have notifications sent whenever one of its objects is created by a user. The registration is performed in the plugin's initialization function, as follows:

register_notification_object('object', 'blog');

A plugin can set a custom notification message by registering for the 'notify:entity:message', 'object' plugin hook.
