Symfony2 / Multiple Upload - symfony

Question

I have complete this: SF2 Handle File Uploads with Doctrin
Now I try to do multiple upload, but can't find newer tutorial for this. All what I found is like 2+ years old, and doesn't work.
Could someone help me with this problem?
I tried change $path, $file to array, and add foreach($this->file as $files) to upload() function, but .... error ....
Here is my code:
Entity: http://pastie.org/private/1qvkhcdhojm1n1orfzuja
Controller: http://pastie.org/private/ppcoezaoicdufg5dsa9dw
Twig: http://pastie.org/private/eclba9e84kzfbh96ecgya
PS: I need Something like this in path(in database): "image1.jpeg,image2.jpeg,image3.jpeg,..."
Sorry, but I'm so dumb with this, just learning..
Thank you

Answer 1

here is some pseudo example code showing how i access to the multiple uploaded files and persist an entity for each uploaded file
$form = $this->createForm('doc',null);
$request = $this->getRequest();
if ('POST' === $request->getMethod()) {
$form->handleRequest($request);
if ($form->isValid()) {
$data=$form->getData();
try {
$i=1;
// upload each file
foreach ($data['file'] as $item) {
$document = new Document();
$document->setFile($item);
// upload file
$document->upload();
$document->setUploadedBy($user->getUserName());
// set thumbnail path
$em->persist($document);
// generate images and set paths
$imageService->optiPathSingle($document);
$i++;
}
return $this->redirect($this->generateUrl('gleisdreieck_core_index'));
} catch (\Exception $e) {
$form->addError(new FormError($e->getMessage()));
}
}
return array(
"form"=>$form->createView(),
"tags"=>$tags
);
} else{
return array(
"form"=>$form->createView(),
"tags"=>$tags
);
}
used formbuilder:
class DocumentType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options) {
$builder->add('file', 'file', array(
'label' => 'Attachments',
'required' => true,
'attr' => array (
'accept' => 'image/*',
'multiple' => 'multiple'
)
))
->add('save', 'submit');
}
