W jaki sposób mogę w widoku (np. views/scripts/index/index.phtml) uzyskać informację czy zalogowany użytkownik ma dostęp do jakiegoś działu? Chciałbym to uzyskać za pomocą funkcji typu isAllowed('controller', 'action') abym mógł ukryć linki w menu, do których użytkownik tak czy inaczej nie ma dostępu. Zend_Acl skonfigurowałem w następujący sposób:

$view = Zend_Layout::getMvcInstance()->getView();
$view->doctype('XHTML1_STRICT');
 
$configuration = new Zend_Config_Ini(APPLICATION_PATH . '/config/app.ini', APPLICATION_ENVIRONMENT);
 
$dbAdapter = Zend_Db::factory($configuration->database);
$dbAdapter->query('SET NAMES utf8');
Zend_Db_Table_Abstract::setDefaultAdapter($dbAdapter);
 
$registry = Zend_Registry::getInstance();
$registry->configuration = $configuration;

$acl  = new Acl($auth);
$frontController->registerPlugin(new Auth($auth, $acl))
                ->setParam('auth', $auth);
 
 
unset($frontController, $view, $configuration, $dbAdapter, $registry);
