這是我想要做的：
我有一個經典的 Folder 物體，它包含 OneToMany 關系中的 Sku 物體作為 ArrayCollection。到現在為止還挺好。
我希望 FolderType 能夠在其中動態創建任意數量的 Sku。為此，我遵循 Symfony 快速跟蹤方法在 javascript 中生成原型。效果很好。
現在，在這種檔案夾形式中，“skus”是物體的陣列集合。在 SkuType 中，我有要上傳的檔案。以下是表格（檔案夾和 Sku）：
$builder
->add('norlogReference', TextType::class, [
'label' => 'Référence du dossier'
])
->add('skus', CollectionType::class, [
'entry_type' => SkuType::class,
'entry_options' => ['label' => false],
'allow_add' => true,
'allow_delete' => true,
'prototype' => 'skus'
]);
至于 SkuType，這是我的上傳欄位：
->add('picture_1', FileType::class, [
'label' => 'Image 1 du produit',
'mapped' => false,
'required' => false,
'attr' => ['accept' => 'image/*']
])
->add('picture_2', FileType::class, [
'label' => 'Image 2 du produit',
'mapped' => false,
'required' => false,
'attr' => ['accept' => 'image/*']
])
這是接收表單的控制器：
/**
* @Route("/new", name="folder_new")
*/
public function new(Request $request): Response
{
$entityManager = $this->getDoctrine()->getManager();
$norlogFolder = new NorlogFolder();
$form = $this->createForm(NorlogFolderType::class, $norlogFolder);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
foreach ($norlogFolder->getSkus() as $sku) {
I want to get both file objects here, pass them in handleUploadedFile(), and use $sku->setPicture1() and setPicture2 with the $newfileName returned by the private method.
$sku->setFolder($norlogFolder);
$sku->setSKU($norlogFolder->getNorlogReference() . '-' . $sku->getSKU());
}
$entityManager->persist($norlogFolder);
$entityManager->flush();
return $this->redirectToRoute('folder_edit', ['id' => $norlogFolder->getId()]);
}
return $this->render('folder/new.html.twig', [
'form' => $form->createView(),
]);
}
以及我想用來處理檔案的小私有方法：
private function handleUploadedFile(UploadedFile $uploadedFile): string
{
$destination = $this->getParameter('kernel.project_dir').'/public/uploads/sku_medias';
$originalFilename = pathinfo($uploadedFile->getClientOriginalName(), PATHINFO_FILENAME);
$newFilename = $originalFilename . '-' . uniqid() . '.' . $uploadedFile->guessExtension();
$uploadedFile->move(
$destination,
$newFilename
);
return $newFilename;
}
和檔案夾表單視圖：

attr: {
class: 'sku-form'
}
}) }}
<div class="form-group">
{{ form_row(form.norlogReference, {

So the question is : how to get these picture_1 and 2 objects (and not path which I already have by remapping them to true), by Sku, in the controller side, in order to handle the files as usual ?
I tried :
- $request->files->get() (result = null, and I have the enctype right in the form)
- $sku->getPicture_1() (result = temporary linux path, but is there a simple way to retrieve the file from that, and on every OS ?)
- Trying to access the $form from inside the sku loop (result = nada)
- $request->get('picture_1') and that ->getData()
- Various weird tries I forgot which gave me nothing
I might miss something obvious here, but I can't think properly on this project anymore. Please don't mind the necessary refactoring for now =) Ty !
uj5u.com熱心網友回復：
你的picuter_1和picture_2是mapped: false。這意味著，你必須使用->getData()（或可能->getNormData()）上的每個SkuType或您的NorlogFolderType
而不是通過SKU的物體集合，遍歷SKU formtypes回圈并獲得直接從資料'picture_1'和'picture_2'場
if ($form->isSubmitted() && $form->isValid())
{
if ($form->has('skus'))
{
foreach ($form->get('skus') as $skuForm)
{
// always check if field named 'picture_1' is there
if ($skuForm->has('picture_1'))
{
/** @var \Symfony\Component\HttpFoundation\File\UploadedFile $firstPic */
$firstPic = $skuForm->get('picture_1')->getData();
//todo: maybe check if null
$picOne = $this->handleUploadedFile($firstPic);
}
// do the same with picture_2 (and others if any)
}
}
}
uj5u.com熱心網友回復：
使用'mapped' => false，您需要像這樣處理上傳的集合：
if ($form->isSubmitted() && $form->isValid()) {
foreach ($form->get('skus') as $formChild)
{
// Get the unmapped picture fields
$uploadedPicture1 = $formChild->get('picture_1')->getData();
$uploadedPicture2 = $formChild->get('picture_2')->getData();
// Get the sku
$sku = $formChild->getData();
// Upload the pictures
$picture1Filename = $this->handleUploadedFile($uploadedPicture1);
$picture2Filename = $this->handleUploadedFile($uploadedPicture2);
// Set the new filenames onto the sku
$sku->setPicture1($picture1Filename);
$sku->setPicture2($picture2Filename);
// Your original code
$sku->setFolder($norlogFolder);
$sku->setSKU($norlogFolder->getNorlogReference() . '-' . $sku->getSKU());
}
}
$entityManager->persist($norlogFolder);
$entityManager->flush();
return $this->redirectToRoute('folder_edit', ['id' => $norlogFolder->getId()]);
}
