Problema con Proccesed en Zend_Form

[utopiko]

Joe pues no idea de como hacer eso que dices para procesar el form, el Auth-Adapter lo he añadido ahora para configurarlo asi:

Código PHP:

<?php
 
class Application_Controller_SignupController extends Zend_Controller_Action
{
    public function getForm()
    {
        return new Application_Form_Signup((array(
            'action' => '/login/process',
            'method' => 'post',
        )));
    }
 
    public function getAuthAdapter(array $params)
    {
        
        // ...or configure the instance with setter methods
 
        $authAdapter = new Zend_Auth_Adapter_DbTable($dbAdapter);
 
        $authAdapter
            ->setTableName('usuarios')
            ->setIdentityColumn('Username')
            ->setCredentialColumn('Password')
        ;
        
        return $authAdapter;
    }
    
    public function preDispatch()
    {
        if (Zend_Auth::getInstance()->hasIdentity()) {
            // If the user is logged in, we don't want to show the login form;
            // however, the logout action should still be available
            if ('logout' != $this->getRequest()->getActionName()) {
                $this->_helpr->redirector('index', 'index');
            }
        } else {
            // If they aren't, they can't logout, so that action should
            // redirect to the login form
            if ('logout' == $this->getRequest()->getActionName()) {
                $this->_helpr->redirector('index');
            }
        }
    }
    
    public function indexAction()
    {
        $this->view->form = $this->getForm();
    }
    
      public function processAction()
    {
        $request = $this->getRequest();
 
        // Check if we have a POST request
        if (!$request->isPost()) {
            return $this->_helper->redirector('index');
        }
 
        // Get our form and validate it
        $form = $this->getForm();
        if (!$form->isValid($request->getPost())) {
            // Invalid entries
            $this->view->form = $form;
            return $this->render('index'); // re-render the login form
        }
 
        // Get our authentication adapter and check credentials
        $adapter = $this->getAuthAdapter($form->getValues());
        $auth    = Zend_Auth::getInstance();
        $result  = $auth->authenticate($adapter);
        if (!$result->isValid()) {
            // Invalid credentials
            $form->setDescription('Invalid credentials provided');
            $this->view->form = $form;
            return $this->render('index'); // re-render the login form
        }
 
        // We're authenticated! Redirect to the home page
        $this->_helper->redirector('http://dkjhgfk', 'http://dkjhgfk');
    }
    
    public function logoutAction()
    {
        Zend_Auth::getInstance()->clearIdentity();
        $this->_helper->redirector('http://dkjhgfk'); // back to login page
    }
    
    
}
