Magento Events Cheat Sheet

Heads up! This article was written over 15 years ago. While it may still be helpful, please verify any information, as my perspectives and practices may have evolved.

Update (05/08/2010): Updated for Magento 1.4.1.1

Magento uses a fantastic event hooking system, following the well known Observer Design Pattern, allowing additional functionality to be plugged in and out without modifying the core code.

It can be difficult to know the names of the various hooks used all over the code base and even more difficult to find where they are used. It is for this reason I have produced a Magento Events Cheat Sheet which will be updated with each new Magento release.
