echo user in view from sessions code igniter

I don’t want to define and store the user in every controller and then pass it to the view.
Here’s my controller:

Login controller:

class LoginController extends CI_Controller {
    function index(){       
        $new['main_content'] = 'loginView';
        $this->load->view('loginTemplate/template', $new);          
    }

    function verifyUser(){

    //getting parameters from view 
    $data = array(
            'username' => $this->input->post('username'),
            'password' => $this->input->post('password')
    );      

    $this->load->model('loginModel'); 
    $query = $this->loginModel->validate($data);

    if ($query){             
        //if the user c validated data variable is created becx we want to put username in session

            $data = array(
                'username' => $this->input->post('username'),
                 'is_logged_in' => true 
            );

           $this->session->set_userdata($data);
           redirect('sessionController/dashboard_area');
    }else{
        $this->index();
    }
}
function logout()
{
    $this->session->sess_destroy();
    $this->index();
}
}



?>

My controller, which I’ve stored in core folder, so now every controller now extends this controller. I think this controller can be customize so I can access the user in every view page which extended this controller:

   class MY_Controller extends CI_Controller{
        function __construct(){
    parent::__construct();
    $this->is_logged_in();

    }   
    function dashboard_area(){
    $data['main_content'] = 'dashboardView';
    $this->load->view('dashboardTemplate/template', $data);         
    }

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

    if(!isset($is_logged_in) || $is_logged_in != true)
    {
        echo 'You don\'t have permission to access this page.';
        redirect('loginController');
    }
}


           }
?>

Here is my simple one member controller which extended the above controller:
Here in index function I am storing the username and then pass into the view which I don’t want to do:

     class CategoryController extends MY_Controller {
   function index(){         
    $data['main_content'] = 'categoryView';         
    $username= $this->session->userdata('username');
    $data['username']=$username;
    $this->load->view('dashboardTemplate/template',$data);
      }

You can just call $this->session->userdata('username') in your view.

It is stored in the session, so you do not have to pass it to the views from the controller.

UPDATE PER COMMENT;
if you want to load a view depending on the base controller (eg user), I would use a template library and set the template to use in the construct of the base controller.

For example (using this template library);

class MY_User extends CI_Controller {
   public __construct() {
      parent::__construct();
      $this->is_logged_in();
      $this->template->set_template('user');
   }
}

class MY_Admin extends CI_Controller {
   public __construct() {
      parent::__construct();
      $this->is_logged_in();
      $this->template->set_template('admin');
   }
}
