Symfony表单只返回令牌字段

Question

我试图创建，呈现，提交和验证没有实体类的表单。

为此，我使用FormBuilderInterface创建了FormType类。但是当我试图在树枝模板中渲染表单时，我总是只使用令牌输入的形式，但没有其他字段。

我的代码如下：

类型定义：

<?php 

namespace AppBundle\Form; 

use Symfony\Component\Form\AbstractType; 
use Symfony\Component\Form\FormBuilderInterface; 

use Symfony\Component\Form\Extension\Core\Type\EmailType; 
use Symfony\Component\Form\Extension\Core\Type\TextType; 

use Symfony\Component\Validator\Constraints\Email; 
use Symfony\Component\Validator\Constraints\NotBlank; 
use Symfony\Component\Validator\Constraints\Length; 

class VendorLeadType extends AbstractType{ 

    /** 
    * @param FormBilderInterface $builder 
    * @param array $options 
    */ 
    public function buidForm(FormBuilderInterface $builder, array $options){ 

     $builder 
      ->add('email', EmailType::class, [ 
       'constraints' => [ 
        new Email(), 
        new Length(['max'=>'100']) 
       ] 
      ]) 
      ->add('name', TextType::class, [ 
       'constraints' => [ 
        new NotBlank(), 
        new Length(['max'=>'100']) 
       ] 
      ]) 
      ->add('phone', TextType::class, [ 
       'constraints' => [ 
        new NotBlank(), 
        new Length(['max'=>'100']) 
       ] 
      ]) 
     ; 
    } 

} 

控制器：

<?php 

namespace AppBundle\Controller; 

use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; 
use Symfony\Bundle\FrameworkBundle\Controller\Controller; 
use Symfony\Component\HttpFoundation\Request; 

use AppBundle\Form\VendorLeadType; 

class DefaultController extends Controller 
{ 
    /** 
    * @Route("/", name="homepage") 
    */ 
    public function indexAction(Request $request) 
    { 
     $form = $this->createForm(VendorLeadType::class); 
     return $this->render('index.html.twig', [ 
      'form' => $form->createView() 
     ]); 
    } 

} 

嫩枝模板

{% extends 'base.html.twig' %} 

{% block body %} 
{{ form(form) }} 
{% endblock %} 

HTML输出

<form name="vendor_lead" method="post"> 
    <div id="vendor_lead"> 
     <input type="hidden" id="vendor_lead__token" name="vendor_lead[_token]" value="..."> 
    </div> 
</form> 

任何想法，我做错了吗？

首先，您的VendorLeadType脚本中存在拼写错误。你需要修正`public function buildForm'的拼写。

要获得表单变量来你的控制器，你需要告诉symfony的不加'mapped' => false,为您的参数指望任何形式的变量映射到实体：

$builder 
     ->add('email', EmailType::class, [ 
      'mapped' => false, 
      'constraints' => [ 
       new Email(), 
       new Length(['max'=>'100']) 
      ] 
     ]) 
     ->add('name', TextType::class, [ 
      'mapped' => false, 
      'constraints' => [ 
       new NotBlank(), 
       new Length(['max'=>'100']) 
      ] 
     ]) 
     ->add('phone', TextType::class, [ 
      'mapped' => false, 
      'constraints' => [ 
       new NotBlank(), 
       new Length(['max'=>'100']) 
      ] 
     ]) 
    ;
