Question

I’m trying to make my custom filter work…

I have the following code in my AuthController:

<?php
public function loginAction()
{
    // Get db var
    $db = $this->_getParam('db');

    // Load loginform
    $loginForm = new Application_Form_Auth_Login();

    // Form posted?
    if ($loginForm->isValid($_POST))
    {
        // Setup adapter
        $adapter = new Zend_Auth_Adapter_DbTable(
          $db,
          'users',
          'username',
          'password'
          );

        // Set identity and credential
        $adapter->setIdentity($loginForm->getValue('username'));
        $adapter->setCredential($loginForm->getValue('password'));

        // Setup Zend_Auth and try to authenticate the user
        $auth = Zend_Auth::getInstance();
        $result = $auth->authenticate($adapter);

        // If authentication succeed
        if ($result->isValid())
        {
            $this->_helper->FlashMessenger('Inloggen geslaagd');
            $this->_redirect('/');
            return;
        }
        else
        {
            $this->_helper->FlashMessenger('Inloggen geslaagd');
        }
    }

    $this->view->loginForm = $loginForm;
}
?>

The code of the form is:

<?php
class Application_Form_Auth_Login extends Zend_Form
{
  /**
   * Default_Form_Auth_Login::init()
   * 
   * Form which authenticates guests
   * 
   * @return void
   */
  public function init()
  {    
    $this->setMethod('post');    

    $this->addElement('text', 'username', array(
        'label' => 'Gebruikersnaam:',
        'required' => true,
        'filters' => array('StringTrim'),
      ));

    $this->addElement('password', 'password', array(
      'label' => 'Wachtwoord:',
      'required' => true,
      'filters' => array('Pcw_Filter_Hash')
      ));

    $this->addElement('hash', 'formToken', array(
      'salt' => 'unique'
      ));

    $this->addElement('submit', 'submit', array(
      'ignore' => true,
      'label' => 'Inloggen',
      )); 

  }  
}

The code of my custom filter is:

<?php

class Pcw_Filter_Hash implements Zend_Filter_interface
{
  /**
   * HashFilter::filter()
   * 
   * @param string $value
   * @return
   */
  public function filter($value)
  {
    return hash('sha512', $value);
  }  
}

When using it this way I keep getting this message:
Message: Plugin by name ‘Pcw_Filter_Hash’ was not found in the registry; used paths: Zend_Filter_: Zend/Filter/

I have found documentation about setting namespaces and adding paths but I can’t get anything to work…

Does anyone has a working solution for my problem? This will be highly apprectiated!

Thanks in advance!

I would rather rewrite you form elements like this one :

$password = new Zend_Form_Element_Password("password");
$password->setLabel("Wachtwoord")
         ->setRequired(true); 

$password->addFilter(new  Pcw_Filter_Hash() );

but I am not sure this might work :

$this->addElement('password', 'password', array(
      'label' => 'Wachtwoord:',
      'required' => true,
      'filters' => array(new Pcw_Filter_Hash())
      ));

and you should double check that Pcw is defined in application.ini

I hope your problem get solved soon 🙂
