Re: Cakephp 1.3 - Detect if Ajax if session expired

hi. 

<?php class AppController extends Controller {

public function beforeFilter(){

if ($this->Auth->User()){

}else{

// if the session expired

$return['login'] = true;

echo json_encode($return); // responseText: "{"login":true}"

}

}

} ?>

And the previous code is more simpler now: 

<?php class TestsController extends AppController {

public function add(){

if($this->Auth->loggedIn()){  // or if($this->Auth->User())

$return['data'] = 'data';

$this->set('return',$return);

}

$this->render('ajax_view','ajax');

}

}

?>

/View/Tests/ajax_view.ctp 

<?php 

if(isset($return)){

echo json_encode($return);

} 

?>

Best regards!

Thank you!

The thing is that the application was written in Cakephp 1.3 and we are not planning to upgrade it any time soon. Thank you for your warning.

The solution provided is very cool, but I'm looking for something that can be implemented in app_controller. This way, it will be global and I will not need to change all the controllers the way they act.

Of course that I will do it your way if this is not possible, but I would be very glad to have another solution since the application is huge.

Thank you!

Best regards!

Hi everyone!

I have the following problem: in my application I have a button that makes an ajax request. If the session expired, the lightbox will load the default login page. I want to detect if the original request came from Ajax but I don't know exactly how to do it, because in app_controller::beforeFilter the request is not Ajax anymore (at least according to $this->RequestHandler->isAjax() ). I have tried to use $this->Auth->ajaxLogin to set a new view for the login if the request comes from an expired session.

Thank you!

Best regards!
