Question

我做了一个非常小的testformular来自我教授自定义表格类在Synfomy中。我没有输出，我没有发现错误。我希望有人可以帮助我。

我来自班级：

<?php
  namespace AppBundle\Form;

  use Symfony\Component\Form\AbstractType;
  use Symfony\Component\Form\FormBuilderInterface;
  use Symfony\Component\OptionsResolver\OptionsResolver;
  use Symfony\Component\Form\Extension\Core\Type\TextType;

  class PfsFormType extends AbstractType
  {
     public function buildTheForm(FormBuilderInterface $builder, array $options)
  {
      $builder
        ->add('name')
    ;
}
   public function configureOptions(OptionsResolver $resolver)
   {
    $resolver->setDefaults(array(
        'data_class' => 'AppBundle\Entity\PfsForm'
    ));
   }
}

我的实体：

<?php
namespace AppBundle\Entity;

class PfsForm
{
private $name;
private $frage;

/**
 * @return mixed
 */
public function getFrage()
{
    return $this->frage;
}

/**
 * @param mixed $frage
 */
public function setFrage($frage)
{
    $this->frage = $frage;
}

/**
 * @return mixed
 */
public function getName()
{
    return $this->name;
}

/**
 * @param mixed $name
 */
public function setName($name)
{
    $this->name = $name;
}

}

控制器应调用表格：

<?php

namespace AppBundle\Controller;

use AppBundle\Entity\PfsForm;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use AppBundle\Form\PfsFormType;

class IndexController extends Controller
{
    public function startAction()
    {
    $pfsForm =  new PfsForm();
    $form = $this->createForm(PfsFormType::class,$pfsForm );
       return $this->render(
       'index.html.twig',array(
           'form' => $form->createView(),
       )
       );
    }
}

枝条模板：

enter code here

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
{{ dump() }}
{{ form_start(form) }}
     {{ form_widget(form) }}
{{ form_end(form) }}
 </body>
</html>

这是Twig转储输出：

    array:2 [▼
    "form" => FormView {#408 ▼
+vars: array:24 [▼
  "value" => PfsForm {#361 ▶}
  "attr" => []
  "form" => FormView {#408}
  "id" => "pfs_form"
  "name" => "pfs_form"
  "full_name" => "pfs_form"
  "disabled" => false
  "label" => null
  "label_format" => null
  "multipart" => false
  "block_prefixes" => array:3 [▶]
  "unique_block_prefix" => "_pfs_form"
  "translation_domain" => null
  "cache_key" => "_pfs_form_pfs_form"
  "errors" => FormErrorIterator {#419 ▶}
  "valid" => true
  "data" => PfsForm {#361 ▶}
  "required" => true
  "size" => null
  "label_attr" => []
  "compound" => true
  "method" => "POST"
  "action" => ""
  "submitted" => false
]
+parent: null
+children: array:1 [▼
  "_token" => FormView {#424 ▶}
]
-rendered: false
  }
  "app" => AppVariable {#435 ▼
    -tokenStorage: TokenStorage {#239 ▶}
    -requestStack: RequestStack {#200 ▶}
    -environment: "dev"
    -debug: true
  }
 ]

谢谢你的帮助米莎

您尝试使用表单buildTheForm的方法不是正确的名称！

尝试使用buildForm，这是正确的：

class PfsFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('name')
        ;
    }
}

在自定义表单类的树枝中没有输出
