Function Reference/remove action

Description

This function removes a function attached to a specified action hook. This method can be used to remove default functions attached to a specific action hook and possibly replace them with a substitute. See also remove_filter(), add_action() and add_filter().

Important: To remove a hook, the $function_to_remove and $priority arguments must match when the hook was added. This goes for both filters and actions. No warning will be given on removal failure.

Usage

<?php remove_action( $tag, $function_to_remove, $priority, $accepted_args ); ?>

Return

(boolean)
