Hi everyone,

First of, I know this is a known problem and I’ve just spent 3 hours going through the solutions people already posted on this forum about this specific problem. Though nothing worked and I’m running out of ideas.

I created my own session class like suggested here: http://ellislab.com/forums/viewthread/138823/ chang,ed the config to increase the sess_time_to_update, etc.

Nothing worked and I still lose my session.
Here’s the relevant controller code from my app, nothing fancy really:

public function interest($categoryName = "")
  {
    error_log(print_r($this->input->request_headers(), TRUE));

    if (!empty($categoryName))
    {
      $this->load->library('session');

      if (!isset($this->session->userdata['userID']))
        show_error("blablabla", 403);
      [...] 

As you can see I print the headers and I do receive a cookie with the session_id, ci_session, user_agent,...

Thank you for you answer but I’ve seen your posts in some similar forum topics, I’ve tried it but it did not change anything… I will try it again though, just in case.

Did you set the session tables user_agent field to varchar(120) ?

I do not save the sessions into my database.

So, it turns out I was already using your class. The strange thing is that everything works fine inside the class, I do have all the session items after the sess_update() but I still lose the session in my controller.

So basically:

/* MY_Session class */
public function sess_update()
    {
        $CI = get_instance();

        if ( ! $CI->input->is_ajax_request())
        {
            parent::sess_update();
        }

        error_log(print_r($this->userdata, true)); // everything is fine here

    } 
/* Controller */
$this->load->library('session');
error_log(print_r($this->session->userdata, true)); // nothing

Well I don’t know what should be my next move here. I tried several things without success and CI seems tricky to debug using tools like Xdebug. So should I just look for another PHP framework?

Ignore please.  The issue can coming from another source.  Nothing to do with this code.  It works perfectly as expected smile
