Codeigniter Session->userdata is null

My project has several views which draw values out of the session->userdata array. the whole project works flawlessly on my development machine, but when I copied the project up to a server, I find that $this->session->userdata is null.

This is the code which inserts some values into the session->userdata array: It is called in the Controller.

    $sessionArray = array(
            'web_id' => $id,
            'paperId' => $paperId,
            'prelimId' => $prelimId,
            'intakeId' => $intakeId,
            'finalId' => $finalId,
     );

     $this->session->set_userdata($sessionArray);

In the view file I call

var_dump($this->session->userdata);

The value returned is null. As I mentioned before, the array is NOT null on my development computer (running WAMP). Does anyone know why?

In order to retrieve all session data as an ASSOC array, you could use the all_userdata() method. (Take a look at CodeIgniter user guide),

You can write that within your Controller and send the returned value to the view, as follows:

$data['userdata'] = $this->session->all_userdata();
$this->load->view('your/view.php', $data); // use $userdata in the view

Note: Using the session library directly inside the views may cause unexpected problems. Try managing your sessions in the Controller instead of the View.

Sorry for posting here in answer block first of all.......... Where you are assigning those values to $sessionArray. What i mean is in model or controller or in view file.

Are you calling var_dump($this->session->userdata) in view file.

Why don't you call that in controller and pass that as an array to view file via controller.

try like this in controller i will get user details in $login array from database for suppose when i submit username and password.

I will send those details to session array like this in model file

$this->session->set_userdata('logged_in_user', $login);

after that in controller if i want use user name from session array i will use like below.

$logged_in = $this->session->userdata("logged_in_user");
$model=array();
$model['logged_in_user']=$logged_in[0];

Once after i assigned to $model array i like to use that in view file so i will pass that $model array to view file from controller like this

$this->load->view('view_file_path',$model);

You can use that array in view file how ever you want from passed array.
