Zend Framework - Navigation set current page title with tag title on navigation.xml

/ Published in: PHP

If you have Zend_Navigation in your application, you will use navigation.xml. This code set the page title ($this->view->headTitle()) with the current page title in navigation.xml.
$navigation->current() doesn't work in my opinion.

/configs/navigation.xml

<nav>
		<home>
			<title>Home</title>
			<label>Home</label>
			<module>admin</module>
			<controller>index</controller>
			<action>index</action>
		</home>
		<communities>
			<title>Communities</title>
			<label>Communities</label>
			<module>admin</module>
			<controller>communities</controller>
			<action>index</action>
		</communities>
         </nav>

class App_Controller_Plugin_Navigation extends Zend_Controller_Plugin_Abstract

    public function preDispatch(Zend_Controller_Request_Abstract $request)
    {        
	//$view = Zend_Registry::get('view');
	$view = Zend_Controller_Front::getInstance()->getParam('bootstrap')->getResource('view');
	$config = new Zend_Config_Xml(APPLICATION_PATH . '/configs/navigation.xml', 'nav');
	$navigation = new Zend_Navigation($config);
	$view->navigation($navigation); 	
	//search current page's title on navigation.xml by Controller Name
	$pages = $view->navigation()->findAllByController($request->getParam('controller'));		
	    if (count($pages) == 1) {
	        $navPage = current($pages);
	    } else {
	        $navPage = $this->_getCurrentPageFromController($pages, $request->getParam('action'));
	    }    
	    $translate = Zend_Registry::get('Zend_Translate');
