I would like to display navigation based on* who* you are. Here is what I've
done in a view_helper, though it would be great to integrate this into my
Acl since I'm checking user roles against it every request already.
Ralph, could you elaborate a bit on : "I would probably implement the Role &
Resource_Interfaces on my models, and do the acl checks.
You could also do some kind of view iteration of the navigation object and
then pass data into a custom built ACL, I would be interested to see if that
kind of solution had merit."
Thanks a lot. It is a huge benefit having access to some of the guys at
Zend. Makes it hard to think about coding anything else.
<?php
class Zend_View_Helper_Navigation extends Zend_View_Helper_Abstract {
public function navigation() {
if(Zend_Auth::getInstance()->hasIdentity()) {
$role = Zend_Auth::getInstance()->getIdentity()->role;
} else {
$role = 'guest';
}
switch ($role) {
case 'guest' :
return null;
break;
case 'user' :
case 'admin' :
$ctrl = Zend_Controller_Front::getInstance();
$controller = $ctrl->getRequest()->getControllerName();
return $this->view->partial('navigation.phtml',
array('controller', $controller));
break;
default:
return null;
}
}
}
