我想知道如何用Symfony2和docrine2一次上傳多個文件。目前，我可以上傳單個文件用symfony2上傳很多文件
ImageType.php
<?php
class ImageType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('file', 'file', array(
'attr' => array(
'class' => 'input-sm form-control',
"accept" => "image/*",
"multiple" => "multiple")
)
);
ImmobilierType.php

//...
->add('image', new ImageType(), array(
'required' => false))

$request = $this->getRequest();
if ($request->getMethod() == 'POST')
{
$form->bind($request);
if ($form->isValid())
{
$em = $this->getDoctrine()->getManager();
$em->persist($immobilier);
$em->flush();
$this->get('session')->getFlashBag()->add('info', 'Immobilier bien enregistré');
return $this->redirect($this->generateUrl('immobilier_show', array('id' => $immobilier->getId())));
