Question

I develop following js in my view.

var url       = '<?php echo base_url(); ?>edit/';
$(document).ready(function(){
    $("#ajax-loader").hide();
    $("#personaldetails-en-di-icon").click(function(){
        $("#ajax-loader").show();
        $.post(url+'ajax/personaldetails/enable', {}, function(data){
            console.log(data);  
        });
     });
});

so,when I click ,it request edit controller.

in edit controller I have
private $id = null;

public function __construct() {
    parent::__construct();
    $this->load->library('session');
    $this->load->library('input');
    $this->load->model('editcv_model');
    $this->load->helper('url');

    $this->id = $this->session->userdata('login');        
    if (intval($this->id) < 1)
        die(json_encode(array('response' => 'not logged in')));
    }

    public function _remap($method = '',$param = array()){
        echo (json_encode(array('response' => 'done')));
    }
}

the first ajax call echo {“response”:”done”} in chrome console,but second and other request echo {“response”:”not logged in”}.
when I check session table in phpmyadmin,it will regenerate session id,with other user-agent

as you seen Mozilla/5.0 (X11; Linux i686) AppleWebKit/537.1 (KHTML, like Gecko) Chrome/21.0.1180.57 Safari/537.1 AlexaToolbar/alxg-3 changed to Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0) AlexaToolbar/alxg-3.0 in ajax request.but I use ubuntu with google chrome browser!!!.

i also had the same problem with CodeIgniter sessions.

i switched to native sessions:

i never really understood the reasoning behind implementing yet another session mechanism (i am not talking about the CI_Session) when php has a good one already. 🙂
