Method Details

asJson() public méthode

This method is a shortcut for sending data formatted as JSON. It will return the [[Application::getResponse()|response]] application component after configuring the [[Response::$format|format]] and setting the [[Response::$data|data]] that should be formatted. A common usage will be: php return $this->asJson($data);

asXml() public méthode

This method is a shortcut for sending data formatted as XML. It will return the [[Application::getResponse()|response]] application component after configuring the [[Response::$format|format]] and setting the [[Response::$data|data]] that should be formatted. A common usage will be: php return $this->asXml($data);

beforeAction() public méthode

public beforeAction ( $action )

bindActionParams() public méthode

This method is invoked by Action when it begins to run with the given parameters. This method will check the parameter names that the action requires and return the provided parameters according to the requirement. If there is any missing parameter, an exception will be thrown.

public bindActionParams ( Action $action, array $params ) : array
$action	yii\base\Action	the action to be bound with parameters
$params	array	the parameters to be bound to the action
Résultat	array	the valid parameters that the action can run with.

goBack() public méthode

You can use this method in an action by returning the Response directly: php stop executing this action and redirect to last visited page return $this->goBack(); For this function to work you have to [[User::setReturnUrl()|set the return URL]] in appropriate places before.

goHome() public méthode

You can use this method in an action by returning the Response directly: php stop executing this action and redirect to home page return $this->goHome();

public goHome ( ) : Response
Résultat	Response	the current response object

redirect() public méthode

This method is a shortcut to [[Response::redirect()]]. You can use it in an action by returning the Response directly: php stop executing this action and redirect to login page return $this->redirect(['login']);

public redirect ( string \| array $url, integer $statusCode = 302 ) : Response
$url	string \| array	the URL to be redirected to. This can be in one of the following formats: - a string representing a URL (e.g. "http://example.com") - a string representing a URL alias (e.g. "@example.com") - an array in the format of `[$route, ...name-value pairs...]` (e.g. `['site/index', 'ref' => 1]`) [[Url::to()]] will be used to convert the array into a URL. Any relative URL will be converted into an absolute one by prepending it with the host info of the current request.
$statusCode	integer	the HTTP status code. Defaults to 302. See for details about HTTP status code
Résultat	Response	the current response object

refresh() public méthode

This method is a shortcut to [[Response::refresh()]]. You can use it in an action by returning the Response directly: php stop executing this action and refresh the current page return $this->refresh();

public refresh ( string $anchor = '' ) : Response
$anchor	string	the anchor that should be appended to the redirection URL. Defaults to empty. Make sure the anchor starts with '#' if you want to specify it.
Résultat	Response	the response object itself

renderAjax() public méthode

This method is similar to [[renderPartial()]] except that it will inject into the rendering result with JS/CSS scripts and files which are registered with the view. For this reason, you should use this method instead of [[renderPartial()]] to render a view to respond to an AJAX request.

public renderAjax ( string $view, array $params = [] ) : string
$view	string	the view name. Please refer to [[render()]] on how to specify a view name.
$params	array	the parameters (name-value pairs) that should be made available in the view.
Résultat	string	the rendering result.
