Good plugins provide actions and filters to allow others (like you!) to modify some of their functionality without having to either create a whole new plugin from scratch or hack away at the original plugin, losing your changes when that plugin gets updated down the road. Learn how to find these actions and filters in other plugins, and use them to bend the plugin to your will.
Learning Outcomes:
- Know what actions and filters are, and how they can be used.
- Be able to create a functionality plugin to modify another plugin’s functionalities.
