Hi Tristan,
You should implement this as a Helper. I recommend this one as an example
(I've used it myself): http://nooclear.com/content/cakephp-2x-menuhelper
Place this class in a file called MenuHelper.php in your /app/Views/Helpers
directory. Then add the following to /app/Controllers/AppController.php:
class AppController extends Controller{
public $helpers = array('Menu');
}
Then inside of your views, whether it be your default layout, an individual
view, or a nested view, add this:
$menu = array( 'options' => array('class' => 'nav-style'), 'items' =>
array( array('title' => 'List Users', 'url' => array('controller' =>
'users', 'action' => 'index')), array('title' => 'Add User', 'url' =>
array('controller' => 'users', 'action' => 'add')), ) ); print
$this->Menu->render($menu);
I recommend reading this for a better understanding of MVC (
http://book.cakephp.org/2.0/en/cakephp-overview/understanding-model-view-controller.html).
It might be worthwhile searching for some other MVC tutorials as well until
you're comfortable with your understanding of the concept.
Cheers,
Tim
