Symfony2表单处理

Question

I am using forms to process my entity data via ajax to an api-method.

My Type Class:

/**
 * @param FormBuilderInterface $builder
 * @param array $options
 */
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add(
        $builder->create('basicdata', 'form', array('virtual' => true))
        ->add('firstname', null, array('required' => true))
        ->add('lastname', null, array('required' => true))
    );        
    $builder->add('contactdetails', new ContactdetailsType());
    $builder->add('medialinks', new MedialinksType());
}

As u can see i seperate my form in 3 sections, one with basedata and 2 additional entities to keep contactdetails and medialinks.

In my JavaScript i have the following listener on the create button:

$('#player_form_create').on('click', function(e){
    e.preventDefault();
    $.ajax({
        type: "POST",
        url: remotePathPlayerCreate,
        data: $('.form').serialize()
    });
});

According to chromes developer tool the POST data look like following:

player_form[basicdata][firstname]:Harvey
player_form[basicdata][lastname]:Specter
player_form[contactdetails][email]:h.specter@pearson.com
player_form[medialinks][website]: http://

In my API action i wanna handle the request and save a new player record:

public function cpostAction()
{
  $player = new Player();
  $form = $this->createForm(new PlayersType(), $player);
  $form->handleRequest($this->getRequest());
  if($form->isValid()){
    $em = $this->getDoctrine()->getManager();
    $em->persist($player);
    $em->persist($player->getContactdetails());
    $em->persist($player->getMedialinks());
    $em->flush();

    return $this->redirectView(
      $this->generateUrl(
        'get_player',
        array('id' => $player->getId())
      ),
      Codes::HTTP_CREATED
    );
  }

  return array(
    'processedForm' => $form
  );
}    

As u might allready know, the problem happens while i want to handle the request. I guess $this->getRequest() does not contain the POST data information in the format needed by the request handler.

When i post data like this, i get a 500 with Expected argument of type \\"Symfony\\\\Component\\\\HttpFoundation\\\\Request\\", \\"array\\" given .

How can i achieve that my POST data is submited as an request object?

Answer 1

I ran into the same problem when building an app with Symfony on server side and AngularJS on client side. Handling the form this way worked:

$content = $this->get('request')->getContent();
if (!empty($content)) { $params = json_decode($content, true); }
else { // return an error or whatever }

$defaultOptions = array('csrf_protection' => false);
$form = $this->createFormBuilder(null, $defaultOptions)
    ->add('email', 'email', array(
        'constraints' => new Constraints\Email(array('message' => 'emailError'))
    ))
    ->getForm();

$form->submit($params);

if ($form->isValid()) {
    ...
}

Of course here I'm not using a type to create the form like you but the result is the same. This assumes that the request payload is something like this:

{email: 'test@example.com'}

好的，我找到了解决方案：根据页面如何使用Submit（）函数处理表单提交，我现在使用$form->submit将我的数组数据$form->submit给表单：

  $form->submit($this->getRequest()->request->get($form->getName()));
