[ZendFramework]Zend_Form - nie znajduje klasy Opcje

[x2008x]

Witam, mam problem z formularzami w ZF2. Jako, że dopiero zaczynam, nie wiem gdzie znajduje się błąd.
Strukturę katalogów mam domyślną.

Oto model:

[PHP] pobierz, plaintext 
<?php
namespace Example;
 
use Zend\Mvc\ModuleRouteListener;
 
 
class Module
{
    public function getConfig()
    {
        return include __DIR__ . '/config/module.config.php';
    }
 
    public function getAutoloaderConfig()
    {
        return array(
            'Zend\Loader\StandardAutoloader' => array(
                'namespaces' => array(
                    __NAMESPACE__ => __DIR__ . '/src/' . __NAMESPACE__,
                ),
            ),
        );
    }
 
 
}

Tutaj controller:

<?php
namespace Example\Controller;
 
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use Zend\Form\Form;
use Zend\Form\Fieldset;
class IndexController extends AbstractActionController
{
    public function indexAction()
    {
 
 
 
		require_once 'form_add.php';
 
		$form = new forms_Formularz();
		$this->view->form = $form;
 
        return new ViewModel();
    }
}

A tutaj sam formularz:

[PHP] pobierz, plaintext 
<?php
namespace Example\Form;
 
use Zend\Form\Form;
 
class forms_Formularz extends Zend_Form
{
	public function init()
	{
		$firstname = new Zend_Form_Element_Text('firstname');
		$lastname = new Zend_Form_Element_Text('lastname');
		$position = new Zend_Form_Element_Select('position');
		$description = new Zend_Form_Element_Textarea('description');
		$submit = new Zend_Form_Element_Submit('btn-submit');
 
		$this->addElement($firstname);
		$this->addElement($lastname);
		$this->addElement($position);
		$this->addElement($description);
		$this->addElement($submit);
	}
}
 
 
?>

Błąd brzmi:

[PHP] pobierz, plaintext 
Fatal error: Class 'Zend_Form' not found in E:\www\zf\module\Example\src\Example\Controller\form_add.php on line 3
[PHP] pobierz, plaintext 

Proszę o pomoc, z góry dzięki.
Widok myślę, że jest zbędny.
