I guess you mean that the problem is that you leave your browser open for X hours, and when you come back the ajax-call will time out since the user session is lost?

If so, doing periodical fetches to a simple “keep-alive” script on the server would solve your problem. If that’s not viable you can extend the session timeout config for PHP.

A different approach would be to catch the ajax-error and redirect to login or similar.

Hi,

I am not sure but I think I saw that with 1.1.9 we have some form of solution for this:

/**

     * @var string value that will be echoed in case that user session has expired during an ajax call.


     * When a request is made and user session has expired, {@link loginRequired} redirects to {@link loginUrl} for login.


     * If that happens during an ajax call, the complete HTML login page is returned as the result of that ajax call. That could be


     * a problem if the ajax call expects the result to be a json array or a predefined string, as the login page is ignored in that case.


     * To solve this, set this property to the desired return value.


     * 


     * If this property is set, this value will be returned as the result of the ajax call in case that the user session has expired.


     * @since 1.1.9


     * @see loginRequired


     */


    public $loginRequiredAjaxResponse;

I know that this does not solve your problem directly but decided to post this for consistency and this would help with eirikhm’s second solution. I don’t know yet how this is used in real application as I just discovered it myself. If anybody has tested it and can post an example that would be great

Hi ,

i have a problem, Once the session expired, a page with AJAX actions will still be displayed normally. But obviously, any AJAX request will be denied, which is confusing. I would like to find a system to inform the user that his session has expired and apply to all pages in the back office.

thanks for your attention

I was having similar issues handling ajax interactions when the session had timed out. The way I resolved the confusion was by having the controller return an error message when an unauthorized call is made to the ajax action (as would happen with a session timeout), detecting this error message in my javascript ajax function, and then redirecting to the homepage / login screen.

In my controller:

public function accessRules()

{

	return array('allow',

		'actions' => array('actionIndex', 'ajaxAction', 'ajaxAnotherAction'), 

		'users' => array('@'),

	),

	array('deny',  // Return error code for ajax actions

		'actions' => array('ajaxAction', 'ajaxAnotherAction'),

		'users' => array('*'),

		'deniedCallback' => function() { echo 'unauthorized access'; }

	),

	array('deny',  // Redirect to index for all other actions

		'users' => array('*'),

		'deniedCallback' => function() { Yii::app()->controller->redirect(array ('/site/index')); }

	),

}

Then, in my javascript:

$.ajax({

	type: "POST",

	url: "controller/action",

	success: function(response){

		// If user denied access (i.e. session timeout), redirect to index

		if (response == 'unauthorized access') {

			alert('Your session has expired.  Please login again.');

			window.location = "/";

			return false;

		}

		// Continue with normal ajax response actions

		$('#newcontent').html(response);

	}

});

Final note: I think you need Yii v1.1.11 or later to use callback in accessRules().
