Question

我有一个带有子类型的表格。使用Java脚本，我可以通过通常的模式更改每行中输入的名称和ID，但是当我提交表单并转储$form->getData()时，它只有一个添加到控制器中的元素。这是我的控制器部分：

    public function add(Request $request)
{
    $snap = new Snap();
    $snapProduct = new SnapProduct();
    $snap->addProduct($snapProduct);

    $form = $this->createForm(SnapType::class, $snap);

    $form->handleRequest($request);

    if ($form->isSubmitted()) {
        if ($form->isValid()) {
            $em = $this->getDoctrine()->getManager();

            $em->persist($snap);
            $em->flush();

            $this->addFlash('success', 'succecc');

            return $this->redirectToRoute('app_panel_snap_details', ['id' => $snap->getId()]);
        }
    }

    return $this->render('panel/snap/new.html.twig', [
        'form' => $form->createView()
    ]);
}

以及我的SnapType：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('registered_at', JalaliDateTimeType::class)
        ->add('number', TextType::class)
        ->add('invoice', TextType::class)
        ->add('account')
        ->add('products', CollectionType::class, [
            'entry_type' => SnapProductType::class,
            'entry_options' => [ 'label' => false ],
            'allow_add' => true,
            'allow_delete' => true,
            'by_reference' => false
        ])
    ;
}

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults([
        'data_class' => Snap::class,
    ]);
}

和我的SnapProductType

        $builder
        ->add('count', TextType::class, [
            'label_format'=> ' '
        ])
        ->add('in_time_price', AmountType::class, [
            'label_format' => ' '
        ])
        ->add('product')
    ;
}

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults([
        'data_class' => SnapProduct::class,
    ]);
}

和呈现后的表单HTML并使用Java脚本添加新行：

<div class="form-group" id="snap-products">
<div class="row product-row" id="snap_products_0">
    <div class="col-md-2">
        <label class="pull-right" for="snap_products_0_product">product </label>
    </div>
    <div class="col-md-4">
        <select id="snap_products_0_product" name="snap[products][0][product]" data-toggle="product-select" class="form-control">[options]</select>
    </div>
    <div class="col-md-3">
        <div class="input-group">

        </button>
    </div>
</div>

修改 Java脚本添加的div＃snap_products_1和div＃snap_products_2

为什么symfony 4收集表单类型只发送第一行？
