Hi,
i have 2 sites with codeigniter , and in one of these, have a lot ajax call (like a ajax chat), in this case i have to use a "patch" with :

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

require_once SYSDIR . '/libraries/Driver.php';
require_once SYSDIR . '/libraries/Session/Session.php';
require_once SYSDIR . '/libraries/Session/drivers/Session_cookie.php';

class MY_Session_cookie extends CI_Session_cookie
{

    public function __construct()
    {
        parent::__construct();
        log_message('info', 'MY_Session_cookie loaded');
    }

    protected function _sess_update($force = false)
    {

        // Do NOT update an existing session on AJAX calls.
        if ($force || !$this->CI->input->is_ajax_request())
            return parent::_sess_update($force);
    }

}

/* End of file MY_Session_cookie.php */
/* Location: ./system/libraries/Session/drivers/MY_Session_cookie.php */ 


This solve constantly logouts for a while, but some times take logouts again, and speciallly when a ajax call was perform when i change current tab, and click in another with no site content(in that case logout is inmediatly when performe a ajax).

i Notice that cookie is correctly send it to validate, but the answer come with another cookie (becouse session expires i supost).. any idea?

This was one of the bugs that never got fixed in the Codeigniter 2.x branch. I'm pretty confident it was fixed in the 3.x branch which is still under development. You can download the latest version on github though.

[InsiteFX]

Not sure if it will work on CI 3.0, I do not use it until it is released.

But it does work for me under CI 2.2.0

Hi,

[dansanti]

well making this file seems to work on CI3, but not fix logout on tabs change (firefox BTW), and this file don't need to be autoloaded, placing this on correct directory, autoload the file.

PHP Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

require_once SYSDIR . '/libraries/Driver.php';
require_once SYSDIR . '/libraries/Session/Session.php';
require_once SYSDIR . '/libraries/Session/drivers/Session_cookie.php';

class MY_Session_cookie extends CI_Session_cookie
{

    public function __construct()
    {
        parent::__construct();
        log_message('info', 'MY_Session_cookie loaded');
    }

    protected function _sess_update($force = false)
    {

        // Do NOT update an existing session on AJAX calls.
        if ($force || !$this->CI->input->is_ajax_request())
            return parent::_sess_update($force);
    }
