PHP Класс yii\base\Controller

__construct() публичный Метод

public __construct ( string $id, Module $module, array $config = [] )
$id	string	the ID of this controller.
$module	Module	the module that this controller belongs to.
$config	array	name-value pairs that will be used to initialize the object properties.

actions() публичный Метод

This method is meant to be overwritten to declare external actions for the controller. It should return an array, with array keys being action IDs, and array values the corresponding action class names or action configuration arrays. For example, php return [ 'action1' => 'app\components\Action1', 'action2' => [ 'class' => 'app\components\Action2', 'property1' => 'value1', 'property2' => 'value2', ], ]; [[\Yii::createObject()]] will be used later to create the requested action using the configuration provided here.

public actions ( )

afterAction() публичный Метод

The method will trigger the [[EVENT_AFTER_ACTION]] event. The return value of the method will be used as the action return value. If you override this method, your code should look like the following: php public function afterAction($action, $result) { $result = parent::afterAction($action, $result); your custom code here return $result; }

public afterAction ( Action $action, mixed $result ) : mixed
$action	Action	the action just executed.
$result	mixed	the action return result.
Результат	mixed	the processed action result.

beforeAction() публичный Метод

The method will trigger the [[EVENT_BEFORE_ACTION]] event. The return value of the method will determine whether the action should continue to run. In case the action should not run, the request should be handled inside of the beforeAction code by either providing the necessary output or redirecting the request. Otherwise the response will be empty. If you override this method, your code should look like the following: php public function beforeAction($action) { your custom code here, if you want the code to run before action filters, which are triggered on the [[EVENT_BEFORE_ACTION]] event, e.g. PageCache or AccessControl if (!parent::beforeAction($action)) { return false; } other custom code here return true; // or false to not run the action }

public beforeAction ( Action $action ) : boolean
$action	Action	the action to be executed.
Результат	boolean	whether the action should continue to run.

bindActionParams() публичный Метод

This method is invoked by Action when it begins to run with the given parameters.

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

createAction() публичный Метод

The method first checks if the action ID has been declared in Controller::actions. If so, it will use the configuration declared there to create the action object. If not, it will look for a controller method whose name is in the format of actionXyz where Xyz stands for the action ID. If found, an InlineAction representing that method will be created and returned.

public createAction ( string $id ) : Action
$id	string	the action ID.
Результат	Action	the newly created action instance. Null if the ID doesn't resolve into any action.

findLayoutFile() публичный Метод

Finds the applicable layout file.

public findLayoutFile ( View $view ) : string | boolean
$view	View	the view object to render the layout file.
Результат	string | boolean	the layout file path, or false if layout is not needed. Please refer to [[render()]] on how to specify this parameter.

getModules() публичный Метод

The first module in the array is the outermost one (i.e., the application instance), while the last is the innermost one.

public getModules ( ) : Module[]
Результат	Module[]	all ancestor modules that this controller is located within.

getRoute() публичный Метод

Returns the route of the current request.

public getRoute ( ) : string
Результат	string	the route (module ID, controller ID and action ID) of the current request.

getUniqueId() публичный Метод

Returns the unique ID of the controller.

public getUniqueId ( ) : string
Результат	string	the controller ID that is prefixed with the module ID (if any).

getView() публичный Метод

The Controller::render, Controller::renderPartial and Controller::renderFile methods will use this view object to implement the actual view rendering. If not set, it will default to the "view" application component.

public getView ( ) : View | View
Результат	View | View	the view object that can be used to render views or view files.

getViewPath() публичный Метод

The default implementation returns the directory named as controller [[id]] under the [[module]]'s [[viewPath]] directory.

public getViewPath ( ) : string
Результат	string	the directory containing the view files for this controller.

render() публичный Метод

The view to be rendered can be specified in one of the following formats: - path alias (e.g. "@app/views/site/index"); - absolute path within application (e.g. "//site/index"): the view name starts with double slashes. The actual view file will be looked for under the [[Application::viewPath|view path]] of the application. - absolute path within module (e.g. "/site/index"): the view name starts with a single slash. The actual view file will be looked for under the [[Module::viewPath|view path]] of [[module]]. - relative path (e.g. "index"): the actual view file will be looked for under [[viewPath]]. To determine which layout should be applied, the following two steps are conducted: 1. In the first step, it determines the layout name and the context module: - If [[layout]] is specified as a string, use it as the layout name and [[module]] as the context module; - If [[layout]] is null, search through all ancestor modules of this controller and find the first module whose [[Module::layout|layout]] is not null. The layout and the corresponding module are used as the layout name and the context module, respectively. If such a module is not found or the corresponding layout is not a string, it will return false, meaning no applicable layout. 2. In the second step, it determines the actual layout file according to the previously found layout name and context module. The layout name can be: - a path alias (e.g. "@app/views/layouts/main"); - an absolute path (e.g. "/main"): the layout name starts with a slash. The actual layout file will be looked for under the [[Application::layoutPath|layout path]] of the application; - a relative path (e.g. "main"): the actual layout file will be looked for under the [[Module::layoutPath|layout path]] of the context module. If the layout name does not contain a file extension, it will use the default one .php.

public render ( string $view, array $params = [] ) : string
$view	string	the view name.
$params	array	the parameters (name-value pairs) that should be made available in the view. These parameters will not be available in the layout.
Результат	string	the rendering result.

renderContent() публичный Метод

Renders a static string by applying a layout.

public renderContent ( string $content ) : string
$content	string	the static string being rendered
Результат	string	the rendering result of the layout with the given static string as the `$content` variable. If the layout is disabled, the string will be returned back.

renderFile() публичный Метод

Renders a view file.

public renderFile ( string $file, array $params = [] ) : string
$file	string	the view file to be rendered. This can be either a file path or a path alias.
$params	array	the parameters (name-value pairs) that should be made available in the view.
Результат	string	the rendering result.

renderPartial() публичный Метод

This method differs from Controller::render in that it does not apply any layout.

public renderPartial ( 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.
Результат	string	the rendering result.

run() публичный Метод

The route can be either an ID of an action within this controller or a complete route consisting of module IDs, controller ID and action ID. If the route starts with a slash '/', the parsing of the route will start from the application; otherwise, it will start from the parent module of this controller.

public run ( string $route, array $params = [] ) : mixed
$route	string	the route to be handled, e.g., 'view', 'comment/view', '/admin/comment/view'.
$params	array	the parameters to be passed to the action.
Результат	mixed	the result of the action.

runAction() публичный Метод

If the action ID is empty, the method will use [[defaultAction]].

public runAction ( string $id, array $params = [] ) : mixed
$id	string	the ID of the action to be executed.
$params	array	the parameters (name-value pairs) to be passed to the action.
Результат	mixed	the result of the action.

setView() публичный Метод

public setView ( View | View $view )
$view	View | View	the view object that can be used to render views or view files.

setViewPath() публичный Метод

Sets the directory that contains the view files.

public setViewPath ( string $path )
$path	string	the root directory of view files.
