I haven't had a chance to fully explore this use case, but I'll throw
out some pseudo code that might get the wheels turning.
Assuming your models might look like this:
class User implements Zend_Acl_Role_Interface {
...
public function getRoleId()
{
return $this->role; // or whatever logic to return roleid
}
}
you could then build an Acl as normal, this would describe which roles
can see which parts of the navigation.
$acl = new Zend_Acl( ... )
You could first look at the integration points that are shipped with
Zend_Nav helper:
http://framework.zend.com/manual/en/zend.view.helpers.html#zend.view.helpers.initial.navigation.acl
I think it might do everything you need :)

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;
}
}
}

The question becomes what do you want to hide/show navigation based on?
Is it based on where you currently are in an application (which
controller/action/module?)
Or is it based on who you are? User/Group information? If its the
latter, I would probably implement the Role & Resource_Interfaces on
my models, and do the acl checks.

Ahh, I did not realize there was a Zend_View_Helper_Navigation.
Thus when I instantiate my Acl class it in the bootstrap it
loads Zend_View_Helper_Navigation from the library/Zend folder,
while in my layout script it is loading from my
application/views/helpers folder. Since I prefix my custom view
helpers with Zend_View_Helper and throw them into the /helpers
directory, it works in the view, but in the bootstrap, only the
library/Zend folder is being searched.
How should I get around this? Or would it just be best to rename
/my/ Navigation view helper?
Also, and perhpas more importantly, how can an Acl class even
know about what is in the application/views/helpers folder??? Hmm.
Nice catch Ralph. Thanks.

Hmm, are you sure that you are loading the correct object?
Where is
this code located? I notice that it implements
Zend_Acl_Resource_Interface, but there is already a class called
Zend_View_Helper_Navigation being loaded by the framework
already right?
Where is your custom code being stored?

As you can see, Zend_View_Helper_Navigation does indeed
implement Zend_Acl_Resource_Interface
What do you guys think?
<?php
class Zend_View_Helper_Navigation extends
Zend_View_Helper_Abstract implements
Zend_Acl_Resource_Interface {
protected $resourceId = 'navigation';
public function navigation() {
return $this->view->partial('navigation.phtml',
array());
}
/**

* @see
library/Zend/Acl/Resource/Zend_Acl_Resource_Interface#getResourceId()
*/
public function getResourceId() {
return $this->_resourceId;
}
}
