string|null $name, array $args )
Fires before the footer template file is loaded.
(string|null) Name of the specific footer file to use. Null for the default footer.
(array) Additional arguments passed to the footer template.
get_footer is a hook that gets run at the very start of the
get_footer() function call. If you pass in the name for a specific footer file, like
get_footer( 'new' ), the
do_action will pass in the name as a parameter for the hook. This allows you to limit your
add_action calls to specific templates if you wish. Actions added to this hook should be added to your functions.php file.
Note: This hook is best to use to set up and execute code that doesn’t get echoed to the browser until later in the page load. Anything you echo will show up before any of the markup is displayed.
