我正在尝试在实体字段中设置选定的值。根据我看到的有关此主题的许多讨论,我尝试设置该data
选项,但默认情况下不会选择任何值:
class EventType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('place', 'entity', array(
'class' => 'RoyalMovePhotoBundle:Place',
'property' => 'name',
'empty_value' => "Choisissez un club",
'mapped' => false,
'property_path' => false,
'data' => 2
))
->add('begin')
->add('end')
->add('title')
->add('description')
;
}
// ...
}
通过寻找更多,我发现有些人不得不停用到实体的表单映射。这似乎合乎逻辑,所以我尝试添加'mapped' => false
选项,但没有成功......
如果有帮助,这是我的控制器:
class EventController extends Controller
{
// ...
public function addAction()
{
$request = $this->getRequest();
$em = $this->getDoctrine()->getManager();
$event = new Event();
$form = $this->createForm(new EventType(), $event);
$formHandler = new EventHandler($form, $request, $em);
if($formHandler->process()) {
$this->get('session')->getFlashBag()->add('success', "L'évènement a bien été ajouté.");
return $this->redirect($this->generateUrl('photo_event_list'));
}
return $this->render('RoyalMovePhotoBundle:Event:add.html.twig', array(
'form' => $form->createView()
));
}
}
和EventHandler
班级:
class EventHandler extends AbstractHandler
{
public function process()
{
$form = $this->form;
$request = $this->request;
if($request->isMethod('POST')) {
$form->bind($request);
if($form->isValid()) {
$this->onSuccess($form->getData());
return true;
}
}
return false;
}
public function onSuccess($entity)
{
$em = $this->em;
$em->persist($entity);
$em->flush();
}
}
我现在有点卡住了,有人有想法吗?
