beforeRedirect( Cake\Event\Event $event , string|array $url , Cake\Network\Response $response )
The beforeRedirect method is invoked when the controller's redirect method is called but before any further action.
If the event is stopped the controller will not continue on to redirect the request. The $url and $status variables have same meaning as for the controller's method. You can set the event result to response instance or modify the redirect location using controller's response instance.
Cake\Event\Event
$event
$url
Cake\Network\Response
$response
Cake\Network\Response|null

If called with the first parameter, it will be set as the controller $this->_components property
Cake\Controller\ComponentRegistry
|null $components

implementedEvents( )
Returns a list of all events that will fire in the controller during its lifecycle. You can override this function to add your own listener callbacks
array

isAction( string $action )
Method to check that an action is accessible from a URL.

Add a component to the controller's registry.
This method will also set the component to a property. For example:

requestAction( string|array $url , array $extra [] )
Calls a controller's method from any location. Can be used to connect controllers together or tie plugins into a main application. requestAction can be used to return rendered views or fetch the return value from controller actions.
Under the hood this method uses Router::reverse() to convert the $url parameter into a string URL. You should use URL formats that are compatible with Router::reverse()
A basic example getting the return value of the controller action:
$variables = $this->requestAction('/articles/popular');
A basic example of request action to fetch a rendered page without the layout.
$viewHtml = $this->requestAction('/articles/popular', ['return']);
You can also pass the URL as an array:
$vars = $this->requestAction(['controller' => 'articles', 'action' => 'popular']);
You can pass POST, GET, COOKIE and other data into the request using the appropriate keys. Cookies can be passed using the cookies
key. Get parameters can be set with query
and post data can be sent using the post
key.
$vars = $this->requestAction('/articles/popular', [ 'query' => ['page' => 1], 'cookies' => ['remember_me' => 1], ]);
By default actions dispatched with this method will use the global $_SERVER and $_ENV values. If you want to override those values for a request action, you can specify the values:
$vars = $this->requestAction('/articles/popular', [ 'environment' => ['CONTENT_TYPE' => 'application/json'] ]);
By default actions dispatched with this method will use the standard session object. If you want a particular session instance to be used, you need to specify it.
$vars = $this->requestAction('/articles/popular', [ 'session' => new Session($someSessionConfig) ]);
$url
$extra
optional [] mixed
