Codeigniter - undefined index error when checking if session exists

I'm getting a undefined index error when checking if a session exists. The error only occurs when a session does not exist.

Controller where the session is created:

$data = array(
                'email' => $this->input->post('email'),
                'is_logged_in' => TRUE
            );

$this->session->set_userdata($data);
redirect('site/index');

Controller where the check takes place:

$is_logged_in = $this->session->userdata['is_logged_in']; // error occurs here

if(!isset($is_logged_in) || $is_logged_in !== TRUE)
{
    $data['main_content'] = 'login_form';
    $this->load->view('includes/template', $data);
}

I've made sure the session library is loaded.

You are treating a method as an associative array. In codeigniter userdata is a function which returns the value of the index you pass it. So your line:

$is_logged_in = $this->session->userdata['is_logged_in'];

Should be:

$is_logged_in = $this->session->userdata('is_logged_in');

$this->session->userdata['is_logged_in'];

Should be

$this->session->userdata('is_logged_in');

The difference is () instead of [] because userdata is a function, not an array.

Per the documentation
