If you override this method, your code should look like the following:
php
public function beforeAction($action)
{
// your custom code here, if you want the code to run before action filters,
// which are triggered on the [EVENT_BEFORE_ACTION](https://www.yiiframework.com/doc/api/2.0/yii-base-controller#EVENT_BEFORE_ACTION-detail) event, e.g. PageCache or AccessControl
if (!parent::beforeAction($action)) {
return false;
}
// other custom code here
return true; // or false to not run the action
}Arguments ​
$action(yii\base\Action) – The action to be executed.
Returns ​
boolean – Whether the action should continue to run.
Throws ​
- yii\web\BadRequestHttpException
if the request is missing a valid CSRF token - yii\web\ForbiddenHttpException
