New to wordpress here. The concept of actions/filters in and of itself is not too difficult to grasp. What I am overwhelmed by is the HUGE amount of actions and filters available. When I am looking at tutorials/guides, they say "simply add this function to the wp_head action or after_setup_theme". Without these tutorials, how on earth would i know to hook that function to that action?
As a beginner, how the heck would i know what is the appropriate action to hook on to? Any advice on how to navigate this? Thanks
