Understanding Source Code
The best way to understand what a hook does is to look at where it occurs in the source code.
- Action hooks look like this:
do_action( "hook_name" ) - Filter hooks look like this:
apply_filters( "hook_name", "what_to_filter" ).
Remember, this hook may occur in more than one file. Moreover, the hook’s context may change from version to version.
