// Add Hook: add_action ('unique _ name_hook ', 'some _ class: hook_test'); // or use a shortcut function to add a Hook: add_action ('unique _ name_hook ', 'other _ class: hello'); add_action ('unique _ name_hook', 'some _ public_function '); // execute the Hook do_action ('unique _ name_hook '); // You can also use the Hook: do_action ();
