Symfony嵌入多个表单集合的多个表格。

Question

我有3个表/实体。我正在尝试创建一个表单，以便在一个表单中保存所有3个表的数据。这些实体太长了，所以我没有在此处添加。

在客户端实体中，我创建了一个数组集合用于其他2个实体。

    protected $Clientservice;
    protected $Hostingaccount;

    public function __construct()
    {
        $this->Clientservice = new ArrayCollection();
        $this->Hostingaccount= new ArrayCollection();
    }
    public function getClientservice()
    {
        return $this->Clientservice;
    }
    public function getHostingaccount()
{
    return $this->Hostingaccount;
}

    public function setClientservice($Clientservice)
    {
        $this->Clientservice = $Clientservice;

        return $this;
    }
    public function setHostingaccount($Hostingaccount)
    {
        $this->Hostingaccount = $Hostingaccount;

        return $this;
    }

我有三个表单：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('CustomerID',IntegerType::class)
        ->add('Sex',TextType::class)
        ->add('Name',TextType::class)
        ->add('FirstName',TextType::class)
        ->add('LastName',TextType::class)
        ->add('Email', EmailType::class)
        ->add('Invoiceemail', EmailType::class)
        ->add('Iban', TextType::class)
        ->add('Bic', TextType::class)
        ->add('SEPAMandateID', TextType::class)
        ->add('LogoUrl', TextType::class)
        ->add('CreationDate', DateType::class)
        ->add('Clientservice', CollectionType::class, array(
            'entry_type' => WhmAdminClientserviceType::class
        ))
        ->add('Hostingaccount', CollectionType::class, array(
            'entry_type' => WhmAdminHostingAccountType::class
        ))
        ->getForm();

}

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => Client::class
    ));
}

客户服务表单

    public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('Description',TextType::class);

}

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => Clientservice::class
    ));
}

托管账户表格：

public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('Domain',TextType::class)
        ->add('Domainip',IntegerType::class)
        ->add('UserName',TextType::class)
        ->add('Owner',TextType::class);

}

public function configureOptions(OptionsResolver $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => Hostingaccount::class
    ));
}

在我的控制器中，我有以下代码：

 public function AddWhmAdminAction(Request $request)
{

    $Client = new Client();

    $form = $this->createForm(WhmAdminType::class, $Client);
    $form->add('submit', SubmitType::class, array(
        'label' => 'Create',
        'attr' => array('class' => 'btn btn-default pull-left')
    ));
    $form->handleRequest($request);
    if ($form->isSubmitted() && $form->isValid()) {

        $em = $this->getDoctrine()->getManager();

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

        $this->get('session')->getFlashBag()->add('green', 'Product created!');
        return $this->redirectToRoute('whmAdmin');
        // flash msg
    }
    //return $form->createView();
    $build['form'] = $form->createView();
    return $this->render('whm/WhmAdminForm.html.twig', $build);

}

在我看来

{{ form_start(form) }}

{% for flashMessage in app.session.flashbag.get('green') %}

    {{ flashMessage }}

{% endfor %}


{{ form_end(form) }}

我遵循了http://symfony.com/doc/current/form/form_collections.html，但是我的表单只显示Client的字段，而没有显示Clientservice和hostingaccount的字段。我如何在同一个表单中显示来自clientservice和hostingaccount的字段？

Answer 1

如果Clientservice和Hostingaccount之间是一对一或多对一的关系，则需要更改以下内容：

->add('Clientservice', CollectionType::class, array(
    'entry_type' => WhmAdminClientserviceType::class
))
->add('Hostingaccount', CollectionType::class, array(
    'entry_type' => WhmAdminHostingAccountType::class
))

to:

->add('Clientservice', WhmAdminClientserviceType::class)
->add('Hostingaccount', WhmAdminHostingAccountType::class)

否则，请放弃您的表单构建器，阅读有关在集合类型中添加和删除项目的说明。

它给我这个错误：表单的视图数据应该是AppBundle\Entity\Clientservice类的实例，但是它是Doctrine\Common\Collections\ArrayCollection类的实例。您可以通过将"data_class"选项设置为null或添加一个视图转换器来避免此错误，该转换器将Doctrine\Common\Collections\ArrayCollection类的实例转换为AppBundle\Entity\Clientservice类的实例。但是当我将"data_class"更改为null时，它不显示其他字段。当我持久化数据时，它只将数据持久化到客户端而不是clientservice和hostingaccount。 - luffy

Clientservice和Hostingaccount是与Client的ManyToOne关系吗？ - miikes

我有这样的代码块：/** * @ORM\ManyToMany(targetEntity="AppBundle\Entity\Clientservice", cascade={"persist"}) */ protected $Clientservice; /** * @ORM\ManyToMany(targetEntity="AppBundle\Entity\Hostingaccount", cascade={"persist"}) */ protected $Hostingaccount; 这段代码位于客户端实体内部。 - luffy

所以，您需要添加脚本来从原型中构建表单集合。请参见我发布的文档。 - miikes
