Question

我是symfony的初学者，我必须使用收集表格建立一个网站来预订节目的门票。

界面很简单，用户选择他想要的门票数量，然后显示尽可能多的表格原型（姓名和姓氏输入）作为所需的门票。这部分适合我。

我在mysql中有2个表“预订”和“票证”，我希望在提交表单后获得此渲染：

表格预订：

预订ID = 1

表格票证

Ticket id =“1”name =“thomas”，surname =“good”，reservation_id =“1”

Ticket id =“2”name =“laura”，surname =“senior”，reservation_id =“1”

但是当我提交表单时，我的表中会得到+1保留，但我的票表中没有数据。

class AdvertController extends Controller
{
    public function formAction(Request $request)
    {
        $em = $this->getDoctrine()->getManager();

        $reservation = new Reservations();

        $form = $this->createForm(new ReservationsType(), $reservation, array(
            'action' => $this->generateUrl('louvre_pages_homepage'),
            'method' => 'POST',
        ));

        $form->handleRequest($request);

        $em->persist($reservation);

        $em->flush();


        return $this->render('LouvrePagesBundle:Pages:index.html.twig', array(
            'form' => $form->createView(),
            ));
    }
}

    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('tickets', CollectionType::class, array(
                'entry_type'    => TicketType::class,
                'allow_add'     => true,
                'allow_delete'  => true,
                'by_reference'  => false,
                'prototype' => true,
                )
            )
            ->add('save', 'submit', array(
                'attr'      => array(
                    'class' => 'btn btn-lg btn-success'
                )
            ));
    }

    public function getName()
    {
        return 'reservations';
    }

    public function setDefaultOptions(OptionsResolverInterface $resolver)
    {
        $resolver->setDefaults(array(
            'data_class' => 'Louvre\PagesBundle\Entity\Reservations',
        ));
    }

我的控制员是对的吗？

我在formAction中看到了2个问题：

无法随时拨打$em->flush();
无论表单验证状态如何，您始终都在调用$em->persist($reservation);

尝试这样做：

if ($form->isSubmitted() && $form->isValid()) {
    $em->persist($reservation);
    $em->flush();

    // now redirect, add flash message, etc.
}
