Yii 2 redirecting to Login if Guest visit the website

Question

I need some advice how to make redirecting to login if someone does not login into the website and he is only Guest

Answer 1

There are two options:

1. You can use the AccessControl as mentioned by @Maksym Semenykhin

2. You can use the option below especially when you would like the logged user to be returned to this page after login.

   public function beforeAction($action){
   if (parent::beforeAction($action)){
       if (Yii::$app->user->isGuest){
           Yii::$app->user->loginUrl = ['/auth/default/index', 'return' => \Yii::$app->request->url];
           return $this->redirect(Yii::$app->user->loginUrl)->send();
       }
   }}
   

   You can also create a custom 'Controller' class which inherits \yii\web\Controller then have all controllers that need authorization inherit your custom controller.

On the login function, replace the redirect part with the following code:

    $return_url = empty(Yii::$app->request->get('return'))? \yii\helpers\Url::to(['/admin/default/index']) :Yii::$app->request->get('return');
    return $this->redirect($return_url);

Answer 2

Use the access section to set access to various actions in the controller.

public function behaviors()
{
    return [
        'verbs' => [
            'class' => VerbFilter::className(),
            'actions' => [
                'delete' => ['POST'],
            ],
        ],
        'access' => [
            'class' => \yii\filters\AccessControl::className(),
            'only' => ['create', 'update','index'],
            'rules' => [
                // deny all POST requests
                [
                    'allow' => false,
                    'verbs' => ['POST']
                ],
                // allow authenticated users
                [
                    'allow' => true,
                    'roles' => ['@'],
                ],
                // everything else is denied
            ],
        ],
    ];
}

use Yii;
use \yii\helpers\Url;

if ( Yii::$app->user->isGuest )
    return Yii::$app->getResponse()->redirect(array(Url::to(['site/login'],302)));

Use can use it in actions or views , but if you need to use it in lots of actions you probably need look at AccessControl and restrict access even before action is fired
