Question

控制器调用具有EntityType的表单以选择要编辑的实体。表单的模板不会返回具有实体ID的控制器。我以为我知道如何做到这一点，但我尝试了多种变化而没有成功。现状：

控制器：

/**
 * @Route("/edit/{id}", name="artist_edit")
 */
public function editArtistAction(Request $request, Defaults $defaults, $id = null)
{
    if (null !== $id) {
        $em = $this->getDoctrine()->getManager();
        $artist = $em->getRepository('AppBundle:Artist')->find($id);
    } else {
        $form = $this->createForm(SelectArtistType::class, null, ['target' => 'edit']);

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

形式：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $target = $options['target'];
    $builder
        ->add('artist', EntityType::class,
            [
                'class' => 'AppBundle:Artist',
                'label' => 'Select artist for ' . $target,
                'choice_label' => function($artist, $key, $index) {
                    return $artist->getLastName() . ', ' . $artist->getFirstName();
                },
                'query_builder' => function (EntityRepository $er) {
                    return $er->createQueryBuilder('a')
                        ->orderBy('a.firstName', 'ASC')
                        ->orderBy('a.lastName', 'ASC');
                },
        ])
        ->add('save', SubmitType::class,
            array(
                'label' => 'Select',
                'label_format' => ['class' => 'text-bold']
    ));
}

模板：

{% extends "base.html.twig" %}
{% block body %}
    <div class="row">
        <div class="col-sm-4"></div>
        <div class="col-sm-4">
            {{ form_start(form) }}
            {{ form_row(form.artist) }}
            {{ form_rest(form) }}
            {{ form_row(form.save) }}
            {{ form_end(form) }}
        </div>
    </div>
{% endblock body %}

您不在任何地方读取来自POST的数据。在您的控制器中，您应该在收到帖子时检查请求。把这样的东西放在控制器的开头，这样你就可以看到你在POST中收到的内容了：

if ($request->isMethod('POST')) {
    var_dump($request->request)
}

然后按照您喜欢的方式处理它。
