Passing a variable data in all controllers in codeigniter

Question

Iam developing a website using codeigniter.I want to pass a particular data to all the controller.I searched and find it can be done by session like below.

$var = $this->session->userdata('passingdata');

But this data loses when history is cleared and when session expires.

Is there any other way to pass variable to all controllers.

You can try this - create MY_Controller in application/core. it looks like

Class MY_Controller extends CI_Controller {

public function __construct() {
    parent::__construct();
    $this->load->model('HomeModel');
    $this->global_data['settings']= $this->HomeModel->getSettings();
}

function display_view($view, $local_data = array()) {
    $data = array_merge($this->global_data, $local_data);
    return $this->load->view($view, $data);
}}

then extend this controller in your all controller

your functions in your controller like

 Class Home extends MY_Controller {
 public function index() {
    $data['title'] = 'test';       
    $this->display_view('home', $data);

}

}
