===========================================	
<?php

class AuthController extends Zend_Controller_Action
{
    public function getForm()
    {
       $form = new Zend_Form();
        $form->setAction('/Auth/login')
             ->setMethod('post');

        // Create and configure username element:
        $username = $form->createElement('text', 'username');
        $username->addValidator('alnum')
                 ->addValidator('regex', false, array('/^[a-z]+/'))
                 ->addValidator('stringLength', false, array(6, 20))
                 ->setRequired(true)
                 ->addFilter('StringToLower');

        // Create and configure password element:
        $password = $form->createElement('password', 'password');
        $password->addValidator('StringLength', false, array(6))
                 ->setRequired(true);

        // Add elements to form:
        $form->addElement($username)
             ->addElement($password)
             // use addElement() as a factory to create 'Login' button:
             ->addElement('submit', 'login', array('label' => 'Login'));
        return $form;
    }

    public function indexAction()
    {
        // render user/form.phtml
        $this->view->form = $this->getForm();
        $this->render('login');
    }

    public function loginAction()
    {
        if (!$this->getRequest()->isPost()) {
            return $this->_forward('index');
        }
        $form = $this->getForm();
        if (!$form->isValid($_POST)) {
            // Failed validation; redisplay form
            $this->view->form = $form;
            return $this->render('login');
        }

        $values = $form->getValues();
        // now try and authenticate....
    }

}
?>
