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.

1865 | * Using this function is the proper way to output all needed components for both TinyMCE and Quicktags. |
1866 | * _WP_Editors should not be used directly. See http://core.trac.wordpress.org/ticket/17144. |
