Yii2 registration problem with facebook?

Question

Yii

Help me to make a normal registration / authorization through facebook. Everything seemed to work out for me, but then I found out that there is a user on facebook without email and when clicking on the facebook icon, it does not register them, because the email field is empty.

public function successCallback($client)
    {
        $attributes = $client->getUserAttributes();
        $user = User::find()->where(['id_facebook'=>$attributes['id']])->one();

        if(!empty($user)){
            Yii::$app->user->login($user);
        }else{
            $user = new User();
            $user->username = $attributes['name'];
            $user->email = $attribute['email'];
            $user->id_facebook = $attributes['id'];
            $user->status = '10';
            $user->generateAuthKey();
            $user->save();

            // Save session attribute user from FB
            $session = Yii::$app->session;
            $session['attributes']=$attributes;
            Yii::$app->user->login($user);
        }
}

How would I think, can I somehow force them to log in through their unique id that comes with the facbook? If so, how?
