RSS API

Overview

The Events API is a core system in Moodle to allow communication between modules.

An event is when something "interesting" happens in Moodle that is worth alerting the system about.

Any Moodle modules can trigger new events (with attached data), and other modules can elect to handle those events with custom functions that operate on the given data.

Examples

Below you will find examples on how to use the RSS functions within your own modules.
