List of Events

When an event is fired, it will provide you with an event object in your callback. That event object typically has access to various types of relevant information through getters. Look at the Event Class further down on this page for details of what the specific event class makes available, or how to use it.

Event Classes

All event classes are in the modmore\Commerce\Events namespace. They all extend the Event class.

Some events only allow you to hook in to listen, while others also allow you to "talk back" with setters on the event class. It's strongly recommended to use a good IDE (like PhpStorm) when writing modules, so you can take advantage of auto-complete and the ability to jump to the calling code to see how things work.
