formform在表单事件上为空 [英] Entity is empty in formModifier on form events

问题描述

我的母语不是我的母语。

English is not my native language, sorry for that.

我有一个会议实体（rendezVous），在这个实体中，我有两个其他映射实体医生docteur）和客户（客户）。

I have a meet entity (rendezVous) and in this entity, i have two others mapped entities doctor(docteur) and customer(client).

我想在选择客户时更改医生名单。

I want to change the list of doctors when choosing a customer.

为此，我在我的RendezVousType中创建一个表单事件，但问题是当我选择一个客户时，客户端实体在我的formModifier中为空。

For that, I create a form events in my RendezVousType, but the problem is when i choose a customer, the Client entity is empty in my formModifier.

    public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('client', EntityType::class, array(
            'class' => 'AppBundle:Client',
            'placeholder' => '',
        ));

    $formModifier = function (FormInterface $form, Client $client = null) {
        $idEspece = null === $client ? 0 : $client->getId();

        $form->add('docteur', EntityType::class, array(
            'class' => 'AppBundle:Docteur',
            'placeholder' => '',
            'query_builder' => function (DocteurRepository $er) use ($idEspece) {
                return $er->getByClientEspece($idEspece);
            },
        ));
    };

    $builder->addEventListener(
        FormEvents::PRE_SET_DATA,
        function (FormEvent $event) use ($formModifier) {
            $data = $event->getData();
            $formModifier($event->getForm(), $data->getClient());
        }
    );

    $builder->get('client')->addEventListener(
        FormEvents::POST_SUBMIT,
        function (FormEvent $event) use ($formModifier) {
            $client = $event->getForm()->getData();
            $formModifier($event->getForm()->getParent(), $client);
        }
    );
}

当我为$ idEspece设置默认值时，查询构建器返回正确的列表。

When I set a default value for $idEspece, the query builder returns the correct list.
