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).

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.
