Model s and views

[eluser]The Casual Bot[/eluser]
hey everyone

I know before i post this someone is going to tell me this is a bad idea and thats why im posting it

i want to load a model in a view fie

because i want it to load the number of unread messages in the nav menu

ie

Inbox [1]

but i don't what to have to make the call in my controllers and pass the variable in ever time i change controller is there a way of make this function available globally to my sidebar view file ????

MY_Controller. Search for it.

not sure what I'm looking for with MY_controller

but i have worked how to get this working what i did is

Created a library
then auto loaded it so now every time A page loads it checks the db for unread msg's and updates the session

Mymsglib

Code:

<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');

class Mymsglib {

    function Mymsglib()
    {
        $CI =& get_instance();
        $CI->load->library('session');
        $session = $CI->session->userdata('userid');
        if (!empty($session)) { //check to see if user is logged in
          $CI->load->model('msg_model');
          $unread = array();
          $unread['unreadmsg']= $CI->msg_model->unread();
          $CI->session->set_userdata($unread);
        }
    }
}

?>

autoload

Code:

$autoload['libraries'] = array('database', 'session', 'mymsglib');

and my sidebar view

Code:

<?=$this->session->userdata('unreadmsg')?>

but im still intrigued by My_Controller could you expand on this a little for me plz :-)

In the MVC paradigm it is acceptable to make read-only calls to a model from a view, and CI will let you do this just as easily as if you were calling if from your controller (you would just pass any select parameter values into the view).
