remove_action( string $hook_name, callable|string|array $callback, int $priority = 10 )

Removes a callback function from an action hook.


Description

This can be used to remove default functions attached to a specific action hook and possibly replace them with a substitute.

To remove a hook, the $callback 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.


Parameters

$hook_name

(Required) The action hook to which the function to be removed is hooked.

$callback

(Required) The name of the function which should be removed.<br> This function can be called unconditionally to speculatively remove a callback that may or may not exist.

$priority

(Optional) The exact priority used when adding the original action callback.

Default value: 10


Return

(bool) Whether the function is removed.
