class AppController extends Controller { public function beforeFilter() { // Check if user is authenticated if (!$this->Auth->user()) { // Redirect to login page return $this->redirect(array('controller' => 'users', 'action' => 'login')); } } }
class AppController extends Controller { public function beforeFilter() { // Check if site is in maintenance mode if ($this->isMaintenanceMode()) { // Render maintenance mode view $this->render('maintenance'); // Stop further execution return $this->_stop(); } } private function isMaintenanceMode() { // Return true if site is in maintenance mode return true; } }In this example, the beforeFilter method checks if the site is in maintenance mode by calling a private method called isMaintenanceMode. If the site is in maintenance mode, the beforeFilter method renders a maintenance view and stops further execution of the controller action. Package library: There is no package library used in this example as the isMaintenanceMode method is a custom method defined in the same AppController class. Overall, the AppController beforeFilter method is a powerful tool that allows developers to run logic before every controller action in a PHP application. It can be used for a range of purposes, such as authentication, maintenance mode checks, and permission checks, among others. The method is built into the CakePHP framework, making it easily accessible to developers.
