class AppController extends Controller { public function beforeRender() { // Set a variable to be used in the view $this->set('title', 'My Website'); // Load a helper that will be needed in the view $this->loadHelper('Form'); } }
class AppController extends Controller { public function beforeRender() { // Check if the user is logged in if (!$this->Auth->user()) { // Redirect the user to the login page return $this->redirect('/login'); } } }This code example shows how to perform a check before rendering the view. In this case, it checks if the user is logged in, and if not, it redirects them to the login page. The package library for AppController is the CakePHP framework.
