WP hooks navigation: Home/browse • Actions index • Filters index
To save our bandwidth, we show only a snippet of code around each occurence of the hook. View complete file in SVN (without highlighting).
The best way to understand what a hook does is to look at where it occurs in the source code.
do_action( "hook_name" )
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.

1231 | * It is recommended to register meta keys for a specific combination of object type and object subtype. If passing |
1232 | * an object subtype is omitted, the meta key will be registered for the entire object type, however it can be partly |
1233 | * overridden in case a more specific meta key of the same name exists for the same object type and a subtype. |
