The main.php layout view:

foreach($layout['media']['css'] as $css_file) {

<link rel="stylesheet" type="text/css" href="<?php echo $css_file; ?>" />

The final step is in your controllers
--snipit--
Code:
class Users extends MY_Controller {
var $sidebar = array(
);
public function __construct() {
parent::__construct();
// this is needed in each controller, basically -- if you have used a different
// layout somewhere, this sets it back to the main one.
$this->load->library('layout', 'layouts/main');
Now in my "page" function, I use:
Code:
public function index() {
$data = array();
$this->layout->view('users/index', $data);
}
Ok so.... how does all this benefit me?
here we go.
1. Now you have a site layout, with headers, footers, side content ... whatever you want
2. All of these parts and pieces are included without having to tell each page to do so.
3. If (for example) the "display" page of users (function display) needs a different layout, all you have to do is tell that function to use a different layout (which you have to define of course) like so:
Code:
public function display() {
$this->layout->layout = 'layouts/plain';
*Note: I do believe I have broken some MVC principles here with using raw includes to files in a "view" file, but this solution has been very clean, and we're not calling controller functions or anything fancy here in the included files. All data needed for them is fed to them accordingly. They are view files, and this is a means of setting up a solid layout without trying to set content for "static views" each time you want to use them.
