requestAction()source public

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()

Examples

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']);

Passing other request data

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],
]);

Sending environment or header values

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']
]);

Transmitting the session

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)
]);

Deprecated

3.3.0 You should refactor your code to use View Cells instead of this method.

Parameters

string|array $url

String or array-based url. Unlike other url arrays in CakePHP, this url will not automatically handle passed arguments in the $url parameter.

array $extra optional []

if array includes the key "return" it sets the autoRender to true. Can also be used to submit GET/POST data, and passed arguments.

Returns

mixed

Boolean true or false on success/failure, or contents of rendered action if 'return' is set in $extra.

createView()source public

createView( string|null $viewClass null )

Returns

Cake\View\ViewBuilder

string or array of string to be appended to _validViewOptions.

boolean $merge optional true

Whether to merge with or override existing valid View options. Defaults to true.
