Class View

View, the V in the MVC triad. View interacts with Helpers and view variables passed in from the controller to render the results of the controller action. Often this is HTML, but can also take the form of JSON, XML, PDF's or streaming files.

CakePHP uses a two-step-view pattern. This means that the template content is rendered first, and then inserted into the selected layout. This also means you can pass data from the template to the layout using $this->set()

View class supports using plugins as themes. You can set

public function beforeRender(\Cake\Event\Event $event)
{
     $this->viewBuilder()->theme('SuperHot');
}

in your Controller to use plugin SuperHot as a theme. Eg. If current action is PostsController::index() then View class will look for template file plugins/SuperHot/Template/Posts/index.ctp. If a theme template is not found for the current action the default app template file is used.

render() public ¶

render( string|null $view = null , string|null $layout = null )

$cell = $this->cell('Taxonomy.TagCloud');

Cells are not rendered until they are echoed.

Parameters

You must indicate cell name, and optionally a cell action. e.g.: TagCloud::smallList will invoke View\Cell\TagCloudCell::smallList(), display action will be invoked by default when none is provided.

array $data optional []

Additional arguments for cell method. e.g.: cell('TagCloud::smallList', ['a1' => 'v1', 'a2' => 'v2']) maps to View\Cell\TagCloud::smallList(v1, v2)

Methods used from Cake\Log\LogTrait

Methods used from Cake\Routing\RequestActionTrait

requestAction() 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)
]);
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.
