Question

我对使用Symfony 2.4.1的表单验证对象有疑问。它是一个没有实体的联系表单，但是有一个处理程序和一个用于邮件内容的Twig模板。

错误是：

ContextErrorException: Catchable Fatal Error: Argument 1 passed to Test\MyBundle\Form\Handler\ContactHandler::onSuccess() must be an instance of Test\MyBundle\Form\Model\Contact, array given, called in C:\Program Files\wamp\www\sf2\src\Test\MyBundle\Form\Handler\ContactHandler.php on line 28 and defined in C:\Program Files\wamp\www\sf2\src\Test\MyBundle\Form\Handler\ContactHandler.php line 36

控制器：

<?php
// src/Test/MyBundle/Controller/MyController.php

namespace Test\MyBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use Symfony\Component\HttpFoundation\Request;
use Test\MyBundle\Form\Type\ContactType;  
use Test\MyBundle\Form\Handler\ContactHandler;
use Symfony\Component\HttpFoundation\Session\Session;

class MyController extends Controller {
  public function contactAction(Request $request) {     
     $form = $this->get('form.factory')->create(new ContactType());

     $request = $this->getRequest();

     $formHandler = new ContactHandler($form, $request,     $this->get('mailer'),$this->get('templating'));

  $process = $formHandler->process();

  if ($process) {
     $this->get('session')->getFlashBag('success', 'Merci de nous avoir contacté, nous vous répondrons dans les meilleurs délais.');
     $this->redirect($this->generateUrl('test_my_contact_success'));
  }

  return $this->render("TestMyBundle:My:contact.html.twig",
        array("form" => $form->createView(),
              "hasError" => $request->getMethod() == 'POST' && !$form->isValid()
        )
  );  // -- render   
  } // -- contactAction() 
} // -- classe

表单类型类：

<?php
namespace Test\MyBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class ContactType extends AbstractType {
    public function buildForm(FormBuilderInterface $builder, array $options) {
       $builder->add('nom', 'text', array('max_length' => 30, 'label' => 'Prénom, nom*', 'required' => false, 'trim' => true, 'attr' => array('size'=>'30')))
               ->add('courriel', 'email', array('max_length' => 255, 'label' => 'Adresse email*', 'required' => false, 'trim' => true, 'attr' => array('size'=>'30')))
              ->add('sujet', 'text', array('max_length' => 255, 'label' => 'Objet*', 'trim' => true, 'attr' => array('size'=>'30')))
              ->add('msg', 'textarea', array('label' => 'Message*', 'attr' => array('rows' => '10','cols' => '80')))
  ->add('submit', 'submit');
} // -- buildForm()

public function setDefaultOptions(OptionsResolverInterface $resolver) {
   return array('data_class' => 'Test\MyBundle\Form\Model\Contact');
} // -- setDefaultOptions()

public function getName() {
      return 'Contact';
   } // -- getName()
} // -- classe

处理程序类：

<?php
// src/Test/MyBundle/Form/Handler/Handler.php
namespace Test\MyBundle\Form\Handler;

use Symfony\Component\Form\Form;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\Templating\EngineInterface;
use Test\MyBundle\Form\Model\Contact;

class ContactHandler {
  protected $request;
  protected $form;
  protected $mailer;
  protected $templating;

  public function __construct(Form $form, Request $request, $mailer, EngineInterface $templating) {
     $this->form = $form;
     $this->request = $request;
     $this->mailer = $mailer;
     $this->templating = $templating;
  } // --  __construct()

  public function process() {
     if ('POST'==$this->request->getMethod()) {
        $this->form->handleRequest($this->request);

        if ($this->form->isValid()) {         
           $contact = $this->form->getData();
           $this->onSuccess($contact);
           return true;
        } // -- isValid()     
   } // -- si POST

   return false;
} // -- process()

protected function onSuccess(Contact $contact) {
    $oMessage = \Swift_Message::newInstance()
               ->setContentType('text/html')
               ->setSubject($contact->getSujet())
               ->setFrom($contact->getCourriel())
               ->setTo('me@toto.com')                    ->setBody($this->templating->render('@TestMyBundle:My:Mails/contact.html.twig',
                                           array('nom' => $contact->getNom(),
                                                 'msg' => $contact->Msg()
                                                )
                                          )
                         );

   return $this->mailer->send($oMessage);    
 } // -- onSuccess()
} // -- classe

对象验证类：

<?php
// src/Test/MyBundle/Form/Model/Contact.php
namespace Test\MyBundle\Form\Model;

class Contact {
  protected $nom;
  protected $courriel;
  protected $sujet;
  protected $msg;

  public function getNom() {
     return $this->nom;
  }

  public function setNom($nom) {
     $this->nom = $nom;
  }

  public function getCourriel() {
     return $this->courriel;
  }

  public function setCourriel($courriel) {
     $this->courriel = $courriel;
  }

  public function getSujet() {
     return $this->telephone
  }

 public function setSujet($sujet) {
    $this->sujet = $sujet;
 }

 public function getMsg() {
    return $this->msg;
 }

 public function setMsg($msg) {
    $this->msg = $msg;
 }
} // -- classe

感谢。

为什么不直接在控制器内发送电子邮件？

问题在于：

if ($this->form->isValid()) {         
    $contact = $this->form->getData(); // returns an array
    $this->onSuccess($contact); // onSuccess needs $contact to be an object
    return true;
}

尝试将数组转换为object：

if ($this->form->isValid()) {         
    $contact = (object)$this->form->getData();
    $this->onSuccess($contact);
    return true;
}

如果强制转换不起作用，请尝试更改onSuccess（）函数内的Contact对象中的参数，如：

$contact['subjet']

表单验证对象出现Symfony 2错误
