I've got a Component that is used by many controllers, and I was wondering if there is a way to access the Controller object from the Component without having to pass it into the Component.
For example I'm currently passing in a reference to the controller into MyAuthComponent:
$this->Auth->isAuthenticated($this);
But, I'd rather be able to invoke this without having to pass the references if possible. Is this possible?
Component callbacks receive controller instance as a parameter. So using your component's startup() callback save the reference to component property and you can then use that in other methods of your component. Check the manual/api for the list of arguments startup() receives.
Here is code example for @ADmad answere
class AuthComponent extends Component {
var $controller = null;
/**
* Startup component
*
* @param object $controller Instantiating controller
* @access public
*/
public function startup(Controller $controller) {
$this->controller = $controller;
}
}
As per cakephp3.x guidelines using registry you can access current controller from within component.
$controller = $this->_registry->getController();
and you can access controller in any component callback methods using event objects mentioned below.
$controller = $event->getSubject();
