最佳结构Codeigniter，恒定的顶级菜单

Question

Maybe a HMVC structure would have been best when I look back.

I load the following views in every controller.

$this->load->view('header');
$this->load->view('DEPENDING');
$this->load->view('header');

In my header-view I have a menu which I show Home | Inbox | Contact us and so on. Now I want to load how many new messages you have like this Home | Inbox (4) | Contact. If Im not wrong the 4 most be loaded thorugh a query every time. Which I then need to include a call to a model in EVERY controller. Like e.g.

$inbox['new_messages'] = $this->Call_the_model->get_new_messages(); // user id go through session

$this->load->view('header', $inbox);
$this->load->view('DEPENDING');
$this->load->view('header');

Am I right? Is there simple solution for me to use - even if Im not using HMVC?

One of the ideas is -

http://ellislab.com/codeigniter/user-guide/general/core_classes.html

class MY_Controller extends CI_Controller {
    function __construct()
    {
        parent::__construct();
        //load your model
        $inbox_new_messages = $this->Call_the_model->get_new_messages();
        //save in session
        $this->session->set_userdata('sess_inbox_new_messages', $inbox_new_messages);
    }

}

then just extend your controllers with new MY_Controllers and

class Welcome extends MY_Controller {

    function __construct()
    {
        parent::__construct();
    }

 }

in your view files - check if that session variable is set and display the number. Hope that helps.
