Understand WordPress Actions and Filters in 5 Minutes

action filters

Actions and filters are two of the most useful features of the WordPress Plugin API.

An action allows you to write a function that runs everytime a certain event happens in WordPress. For example, actions can allow you to make something happen every time a post is published. WordPress provides hundreds of actions that you can hook into, but you can also create your own actions.
