Yii 2 redirecting to Login if Guest visit the website - redirect

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

Answer 2

There are two options:
You can use the AccessControl as mentioned by #Maksym Semenykhin
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 3

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
],
],
];
}

Answer 4

works for me.
use Yii;
use \yii\helpers\Url;
if ( Yii::$app->user->isGuest )
return Yii::$app->getResponse()->redirect(array(Url::to(['site/login'])));

Answer 5

The Access Control Filter will do the work for you and redirects you to the configured user->loginUrl (config/main.php) if an action is not allowed.
Add the rule:
array('deny',
'users'=>array('?'),
),
To your base controller (f.e. ‘Controller’) where all your controllers are inherited from.

I used index.php in my web/admin directory
This is the sample my index.php
<?php
// comment out the following two lines when deployed to production
defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');
require __DIR__ . '/../../vendor/autoload.php';
require __DIR__ . '/../../vendor/yiisoft/yii2/Yii.php';
$config = require __DIR__ . '/../../config/web.php';
$config["controllerNamespace"]='app\controllers\backend';
(new yii\web\Application($config))->run();
if(Yii::$app->user->isGuest){
$request_headers = apache_request_headers();
$srv=$request_headers['Host'];
header("Location: https://".$srv);
die();
}
