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

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
