Yii check if user is logged before every page - php

Question

I have to check if user is logged before rendering every page example:
http://mypage.com/site/about
at begining check if user is logged in, if not - redirect tom login page
I don't want to add it in every single componene, how to to this?

Answer 1

You can also check using this if it is true then user is not logged in else logged in
if(Yii::app()->user->isGuest){
//not logged user
}else{
//loggedin user
}

Answer 2

Use access rule to achevie this would be a better way:
public function accessRules()
{
return array(
array('allow', // allow all users to perform 'index' and 'contact' actions
'actions'=>array('index','contact'),
'users'=>array('*'),
),
array('allow', // allow authenticated user to perform 'delete' and 'update' actions
'actions'=>array('update','delete'),
'users'=>array('#'),
),
array('deny', // deny all users
'users'=>array('*'),
),
);
}
if you really want one-place checking,,then go to component/controller and do it in the controller. because all controller inherits from that controller.

Answer 3

You can write a check in the init() function of the controller. Which will redirect the user if he is not logged in
public function init()
{
if(!isset(Yii::app()->session['user']))
{
$this->redirect(array('login/'));
}
}

Answer 4

This works for me
public function beforeAction(CAction $action)
{
if(!isset(Yii::app()->user->user_id) && !($action->controller->id == 'site' && $action->id == 'login'))
{
$this->redirect(array('site/login'));
}
return true;
}
You need to just add the above function in component/Controller.php

Answer 5

For a global solution add accessControl to your base controller (by default protected/components/CController.php).
public function filters(){
return array('accessControl');
}
public function accessRules()
{
return array(
array('allow',
'users'=>array('#'),
),
array('deny', // deny all users
'users'=>array('*'),
),
);
}
Then in the controller with your login action edit the accessRules to allow all users to access the login page
public function accessRules()
{
return array_merge(array(
'allow',
'actions'=>array('login'),
'users'=>array('*'),
),parent::accessRules()
);
}

Answer 6

Extend components/Controller with beforeAction
public function beforeAction(CAction $action)
{
if(!isset(Yii::app()->session['user']) && !($action->controller->id == 'site' && $action->id == 'login'))
{
$this->redirect(array('site/login'));
}
return true;
}

Answer 7

you can add global behavior to your config:
'as access' => [
'class' => \yii\filters\AccessControl::className(),
'rules' => [
[
'actions' => ['login', 'error', 'resend', 'forgot'],
'allow' => true,
],
// allow authenticated users
[
'allow' => true,
'roles' => ['#'],
],
]
],

Answer 8

Sorry for zombie posting, but I use isGuest.
if (Yii::app()->user->isGuest)
{
$this->redirect('login/page');
}

Answer 9

Write a code to check if the user is logged in or not in a different file.
Then include that php page in every file.
You will just have to write the following code.
include('checklogin.php');
In the checklogin.php page, you may write the following to check if the cookie is set.
isset(cookie('<name_of_cookie>'))
{
//User in already logged in
}
else
{
//Redirect to login page
}
