actions() public method

Defined in: yii\base\Controller::actions()

Declares external actions for the controller.

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,

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 array actions ( )

                public function actions()
{
    return [];
}

            
afterAction() public method

Defined in: yii\base\Controller::afterAction()

This method is invoked right after an action is executed.

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:

public function afterAction($action, $result)
{
    $result = parent::afterAction($action, $result);
    // your custom code here
    return $result;
}
public mixed afterAction ( $action, $result )
$action yii\base\Action

The action just executed.

$result mixed

The action return result.

return mixed

The processed action result.

                public function afterAction($action, $result)
{
    $event = new ActionEvent($action);
    $event->result = $result;
    $this->trigger(self::EVENT_AFTER_ACTION, $event);
    return $event->result;
}

            
ansiFormat() public method

Defined in: yii\console\Controller::ansiFormat()

Formats a string with ANSI codes.

You may pass additional parameters using the constants defined in yii\helpers\Console.

Example:

echo $this->ansiFormat('This will be red and underlined.', Console::FG_RED, Console::UNDERLINE);
public string ansiFormat ( $string )
$string string

The string to be formatted

                public function ansiFormat($string)
{
    if ($this->isColorEnabled()) {
        $args = func_get_args();
        array_shift($args);
        $string = Console::ansiFormat($string, $args);
    }
    return $string;
}

            
attachBehavior() public method

Defined in: yii\base\Component::attachBehavior()

Attaches a behavior to this component.

This method will create the behavior object based on the given configuration. After that, the behavior object will be attached to this component by calling the yii\base\Behavior::attach() method.

See also detachBehavior().

public yii\base\Behavior attachBehavior ( $name, $behavior )
$name string

The name of the behavior.

$behavior string|array|yii\base\Behavior

The behavior configuration. This can be one of the following:

return yii\base\Behavior

The behavior object

                public function attachBehavior($name, $behavior)
{
    $this->ensureBehaviors();
    return $this->attachBehaviorInternal($name, $behavior);
}

            
attachBehaviors() public method

Defined in: yii\base\Component::attachBehaviors()

Attaches a list of behaviors to the component.

Each behavior is indexed by its name and should be a yii\base\Behavior object, a string specifying the behavior class, or an configuration array for creating the behavior.

See also attachBehavior().

public void attachBehaviors ( $behaviors )
$behaviors array

List of behaviors to be attached to the component

                public function attachBehaviors($behaviors)
{
    $this->ensureBehaviors();
    foreach ($behaviors as $name => $behavior) {
        $this->attachBehaviorInternal($name, $behavior);
    }
}

            
beforeAction() public method

Defined in: yii\console\Controller::beforeAction()

This method is invoked right before an action is executed.

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:

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 boolean beforeAction ( $action )
$action yii\base\Action

The action to be executed.

return boolean

Whether the action should continue to run.

                public function beforeAction($action)
{
    $silentExit = $this->silentExitOnException !== null ? $this->silentExitOnException : YII_ENV_TEST;
    Yii::$app->errorHandler->silentExitOnException = $silentExit;
    return parent::beforeAction($action);
}

            
behaviors() public method

Defined in: yii\base\Component::behaviors()

Returns a list of behaviors that this component should behave as.

Child classes may override this method to specify the behaviors they want to behave as.

The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

'behaviorName' => [
    'class' => 'BehaviorClass',
    'property1' => 'value1',
    'property2' => 'value2',
]

Note that a behavior class must extend from yii\base\Behavior. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using getBehavior() or be detached using detachBehavior(). Anonymous behaviors can not be retrieved or detached.

Behaviors declared in this method will be attached to the component automatically (on demand).

public array behaviors ( )
return array

The behavior configurations.

                public function behaviors()
{
    return [];
}

            
bindActionParams() public method

Defined in: yii\console\Controller::bindActionParams()

Binds the parameters to the action.

This method is invoked by yii\base\Action when it begins to run with the given parameters. This method will first bind the parameters with the options available to the action. It then validates the given arguments.

public array bindActionParams ( $action, $params )
$action yii\base\Action

The action to be bound with parameters

$params array

The parameters to be bound to the action

return array

The valid parameters that the action can run with.

render() public method

Defined in: yii\base\Controller::render()

Renders a view and applies layout if available.

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 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 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 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.
  1. 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 layout path of the application;
  • a relative path (e.g. "main"): the actual layout file will be looked for under the layout path of the context module.

If the layout name does not contain a file extension, it will use the default one .php.

public string render ( $view, $params = [] )
$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.

{
    $layoutFile = $this->findLayoutFile($this->getView());
    if ($layoutFile !== false) {
        return $this->getView()->renderFile($layoutFile, ['content' => $content], $this);
    }
