genesistant_get_hooks() – Return the attached hooks

Description

Return the attached hooks

Note: It's safe to use foreach over $wp_filter[ $tag ] since this routine's invoked for the 'all' hook not the hook in question. But I've copied the code for bw_trace_get_attached_hooks() anyway since it's more 'complete' See http://php.net/manual/en/control-structures.foreach.php

Usage

$string = genesistant_get_hooks( $tag );

Parameters

$tag

( string ) required – the action hook or filter

Returns

string the attached hook information
