Zendcasts Forum

I remember Udo showed me some code that did something to this effect. It might be worth asking him.

I have ACL working with Zend_Navigation without using view partials. The problem is that the default rendering of Zend_Navigation is not as flexible as I'd like (it doesn't allow you to customize the individual <li> elements), so I need to use a view partial to render it out myself. This is done using the navigation menu view helper and invoking the "setPartial()" method, passing my partial view path in (see http://framework.zend.com/manual/en/zen … ion.menu).

The problem is that when you tell it to use a partial, it skips the default rendering method (renderMenu()), which happens to also contain the logic for filtering out menu items based on ACL (take a look in Zend/View/Helper/Navigation/Menu.php). So the logic for filtering out the items need to be reimplemented in the view partial (or somewhere else). Seems like there was debate about this in the initial proposal (http://framework.zend.com/wiki/display/ … n+Skoglund). I guess my big question is how to re-implement that ACL logic.

For reference, here's how I have my ACL and Navigation setup in my application:

[code=php]
Bootstrap.php
...
    protected function _initAcl() {
        ...

        $acl = new Zend_Acl();
        $aclData = new Zend_Config_Xml(APPLICATION_PATH . '/configs/acl.xml', $module);
        foreach ($aclData->roles->role as $role) {
            $acl->addRole(new Zend_Acl_Role($role));
        }

        foreach ($aclData->resources->resource as $resource) {
            $acl->addResource(new Zend_Acl_Resource($module . '.' . $resource));
        }

        // If an allow whitelist is specified, process
        if (!empty($aclData->whitelist->allow)) {

            // Convert it to an array
            $whitelist = $aclData->whitelist->allow->toArray();

            // If there's more than one allow rule, iterate over and process
            // each
            if (isset($whitelist[0])) {
                foreach ($whitelist as $allow) {
                    $acl->allow($allow['role'], $module . '.' . $allow['resource']);
                }
            } else {
                $acl->allow($whitelist['role'], $module . '.' . $whitelist['resource']);
            }
        }
        // If a blacklist is specified, process
        if (!empty($aclData->blacklist->allow)) {

            // Convert it to an array
            $blacklist = $aclData->blacklist->allow->toArray();

            // If there's more than one allow rule, iterate over and process
            // each
            if (isset($blacklist[0])) {
                foreach ($blacklist as $deny) {
                    $acl->deny($deny['role'], $module . '.' . $deny['resource']);
                }
            } else {
                $acl->deny($blacklist['role'], $module . '.' . $blacklist['resource']);
            }
        }

        // Store the acl in the registry
        Zend_Registry::set('acl', $acl);
        return $acl;
    }

...

    protected function _initNavigation() {
        ...

        // Load the current module's navigation section within the navigation
        // config
        $config = new Zend_Config_Xml(APPLICATION_PATH . '/configs/navigation.xml', MODULE);

        // Create a new navigation object
        $navigation = new Zend_Navigation($config);

        // Set the navigation object to the view
        Zend_Layout::getMvcInstance()
                    ->getView()
                    ->navigation($navigation);
    }[/code]
Controller_Plugin_Init.php (this is a controller plugin that handles identity retrieval and user role)
[code=php]
    public function dispatchLoopStartup(Zend_Controller_Request_Abstract $request) {
        ...

        $acl = Zend_Registry::get('acl');

        // Expose the acl to the view navigation so it knows which items to
        // render
        Zend_Layout::getMvcInstance()
                   ->getView()
                   ->navigation()
                   ->setAcl($acl)
                   ->setRole($user->Role->name);
    }[/code]
And in my layout script
[code=php]
...
echo $this->navigation()->menu();
...[/code]

Hi I use this:

Notice the : $this->navigation()->accept($page)
Seems to work with all the tests I have done

Had to do all this though cause I needed an extra Span to control tabs display - annnoying!

[code=php]
<?php

/* vim: set expandtab tabstop=4 shiftwidth=4 softtabstop=4: */

/**
* Navigational Menu partial to output the navigation correctly
*
* <code>
* // User in the general Layout
* echo $this->navigation()->menu()->setPartial(array('menu.phtml', 'default'));
* </code>

*/

// Set the filter option for the Active navigation
$this->navigation()->findByResource(
  Zend_Controller_Front::getInstance()->getRequest()->module .
  Zend_Controller_Front::getInstance()->getRequest()->controller
);
?>

<ul>

<?php
// Loop through the container
foreach ($this->container as $page) {

    // Check whether the page is set as Visible and also it is accepted through the ACL
    if ($page->isVisible() && $this->navigation()->accept($page)) {

        // Create the class to use if the tab is active
        $liClass = $page->isActive(false) ? ' class="active"' : '';

        // HTML to generate the tabs
?>
        <li<?php echo $liClass; ?>>
          <a href="<?php echo $page->getHref(); ?>" title="<?php echo $page->getTitle(); ?>">
          <span><?php echo $page->getLabel() ?></span></a>
        </li>
<?php
    }
}
?>

</ul>
[/code]

@iwarner what do you mean about the forum? did you have trouble activating your account?

Nice to know it's a feature not implemented in the original Zend_Navigation.
I have to use a check in my partial last time I use Zend_Navigation and found that very "inadequate".

Thanks for the solution came with.

Speaking of Zend_Navigation is there a way to know if a "link" is active (not by setting it but in sort of automatic way) it will be very helpfull for design issue.

I may have explain a bit more the context.
isActive() is working for mvc page only for uri page  the ref says

So even if your page uri for example :
$page = new Zend_Navigation_Page_uri(array(
    'label' => 'Home',
    'uri'   => 'http://www.example.com/'
));

isActive() doesn't work for your home page

you have to make it manualy active and reflect the state on all the navigation every time the page change...

Well thanks for your answers and sorry for the late those thanks come...
I know that Page_Uri was intended (not sure if it's the right word Frenchy inside) for external URL. But i choose to use it because i have a sort of link generator in my CMS and it was more easy to handle "user typed" url (that could be internal or not) and i failed trying to reverse those url to the mvc style for the case they were internal ones. I think i must digg harder and found a way to do that it will be far better.

ryan.horn
I would like to explain me more detail
with the same problem I want to make a custom menu with ACL
I need your help please let me know exactly
that part add the code you wrote

thanks
