🔞 ADULT: Function Reference/do action

Calls the callback functions that have been added to an action hook.

Description

This function invokes all functions attached to action hook $hook_name.
It is possible to create new action hooks by simply calling this function, specifying the name of the new hook using the $hook_name parameter.

You can pass extra arguments to the hooks, much like you can with apply_filters().

Example usage:

// The action callback function.
function example_callback( $arg1, $arg2 ) {
    // (maybe) do something with the args.
}
add_action( 'example_action', 'example_callback', 10, 2 );

/*
 * Trigger the actions by calling the 'example_callback()' function
 * that's hooked onto `example_action` above.
 *
 * - 'example_action' is the action hook.
 * - $arg1 and $arg2 are the additional arguments passed to the callback.
do_action( 'example_action', $arg1, $arg2 );

Parameters

$hook_namestringrequired: The name of the action to be executed.
$argmixedoptional: Additional arguments which are passed on to the functions hooked to the action. Default empty.
