Symfony2表单：意外“无POST参数”

标签： php symfony wampserver symfony-forms symfony-2.8

我正试图通过Symfony的Form组件来持久化对象。它不起作用。

提交表单时，Symfony会将我重定向到实际表单，之前提交的数据会出现在使用GET方法的网址中。在Profiler中，我可以观察到“没有POST参数”。

控制器：

<?php

namespace AppBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\HttpFoundation\Request;
use AppBundle\Entity\Quest;
use AppBundle\Form\QuestType;

class QuestController extends Controller
{
\\...
    /**
     * @Route("/admin/quest/add", name="quest_add")
     */
  public function addAction(Request $request)
  {
    $quest = new Quest();
    $form = $this->createForm(QuestType::class, $quest);
    $form->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid()) {
      $em = $this->getDoctrine()->getManager();
      $em->persist($quest);
      $em->flush();

      return $this->redirectToRoute('quest_view');
    }

    return $this->render('admin/quest/add.html.twig', array(
      'form' => $form->createView(),
    ));
  }
}

类型：

<?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\DateTimeType;
use Symfony\Component\Form\Extension\Core\Type\TextType;
use Symfony\Component\Form\Extension\Core\Type\TextareaType;
use Symfony\Component\Form\Extension\Core\Type\IntegerType;

class QuestType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
        ->add('questName',      TextType::class)
        ->add('questCost',      IntegerType::class)
        ->add('nbEnigma',       IntegerType::class)
        ->add('dateStart',      DateTimeType::class)
        ->add('dateEnd',        DateTimeType::class)
        ->add('rewardFinish',   IntegerType::class)
        ->add('rewardFurther',  IntegerType::class)
        ->add('speech',         TextareaType::class)
        ;
    }
\\...
}

观点：

/* ... */
<div class="well">
  {{ form_start(form) }}
  {{ form_errors(form) }}

  {{ form_row(form.questName) }}
  /* ... */

  <input type="submit" value="Create" method="post" class="btn btn-default pull-right" />

  {{ form_end(form) }}
</div>
/* ... */

请注意，我暂时不使用验证。

我使用的实体没问题，通过Symfony控制台在我的PostgreSQL数据库中创建了相应的表，参数的配置也可以。如果需要，我可以发布这些元素。

那么可能出现什么问题？这是我的Wamp安装或配置中的问题，例如Apache的问题吗？事实是我不知道问题出在哪里。

请注意，我是网络开发的初学者。我实际上尝试学习PHP以及Symfony2。

评论后的编辑

1）结果HTML显示Twig渲染生成的表单将表单的方法设置为“POST”： <form name="quest" method="post">

2）在@Method({"GET", "POST"}) @Route下use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;添加/admin并没有改变任何内容。

3.1）关于我的环境的信息：

  • Wampserver 2.5（32位和PHP 5.5.12，Apache 2.4.9）
  • PostgreSQL 9.3.2
  • Symfony 2.8.1，使用标准版+ FOSUserBundle~2.0@dev
  • 使用Doctrine2
  • 在开发环境（app_dev.php）中以SuperAdmin（位于我的<?php namespace AppBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route; use Symfony\Component\HttpFoundation\Response; use Symfony\Component\HttpFoundation\Request; use Symfony\Component\Form\Extension\Core\Type\TextType; class QuestController extends Controller { // ... /** * @Route("/admin/test/add", name="test") */ public function testAction(Request $request) { $defaultData = array('message' => 'Type your message here'); $form = $this->createFormBuilder($defaultData) ->add('nametest', TextType::class) ->getForm(); $form->handleRequest($request); if ($form->isValid()) { $data = $form->getData(); } return $this->render('admin/test.html.twig', array( 'form' => $form->createView(), )); } } 目录中的后端表单）工作。

3.2）在我的同一环境中，我复制了3种不同的在线教程（来自Symfony的书籍，来自openclassrooms.com，以及来自dynamic-mess.com）中显示的各种表格，这一切都以同样的方式结束。

4）以防万一，我只是重新启动项目，重新安装Symfony，使用相同的版本和相同的配置，使用相同的Wampserver和PostgreSQL。我只是密切注意防止错过一些步骤。它仍然无法正常工作。

5）在我的环境中测试基本HTML表单： 使用没有类的表单（没有实体）

控制器：

/* ... */

<div class="well">
  {{ form_start(form) }}
  {{ form_errors(form) }}

  {{ form_row(form.nametest) }}
  <input type="submit" value="Create" method="post" class="btn btn-default pull-right" />

  {{ app.request }}

  {{ form_end(form) }}
</div>

/* ... */

观点：

{{ app.request }}

对于此测试，我使用了Twig全局模板变量GET /gowinquest/web/app_dev.php/admin/test/add HTTP/1.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Encoding: gzip, deflate Accept-Language: fr,fr-FR;q=0.8,en-US;q=0.5,en;q=0.3 Cache-Control: max-age=0 Connection: keep-alive Cookie: __utma=111872281.2124856035.1451232730.1452442012.1452447222.32; __utmz=111872281.1451232730.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); __utmc=111872281; PPA_ID=not8odr8dlslv6eoo25l2llai6; webfx-tree-cookie-persistence=wfxt-14+wfxt-36+wfxt-20+wfxt-4+wfxt-16+wfxt-18+wfxt-6; PHPSESSID=h94nvh0nn315po8np66httkv56; __utmb=111872281.0.10.1452447222 Host: localhost User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0 X-Php-Ob-Level: 1 。

在点击提交按钮之前，页面会显示以下信息：

GET /gowinquest/web/app_dev.php/admin/test/add?form%5Bnametest%5D=blablabla&form%5B_token%5D=pzhE6hrzsNf3EYbHJLmEXf0miAh4J5jeOH_ccrmlmW4 HTTP/1.1 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Encoding: gzip, deflate Accept-Language: fr,fr-FR;q=0.8,en-US;q=0.5,en;q=0.3 Connection: keep-alive Cookie: __utma=111872281.2124856035.1451232730.1452442012.1452447222.32; __utmz=111872281.1451232730.1.1.utmcsr=(direct)|utmccn=(direct)|utmcmd=(none); __utmc=111872281; PPA_ID=not8odr8dlslv6eoo25l2llai6; webfx-tree-cookie-persistence=wfxt-14+wfxt-36+wfxt-20+wfxt-4+wfxt-16+wfxt-18+wfxt-6; PHPSESSID=h94nvh0nn315po8np66httkv56; __utmb=111872281.0.10.1452447222 Host: localhost Referer: http://localhost/gowinquest/web/app_dev.php/admin/test/add User-Agent: Mozilla/5.0 (Windows NT 6.3; WOW64; rv:43.0) Gecko/20100101 Firefox/43.0 X-Php-Ob-Level: 1

在之后，生成的页面会丢弃这些信息：

@Method({"GET", "POST"})

6）我在我的实体上尝试了Symfony的CRUD控制器和模板生成器，IT WORKED！我的数据是通过POST发送的，并已在数据库中注册。

但这对我来说仍然是一个巨大的谜，因为Controller中生成的方法和Symfony的Form与我之前手动尝试的方法相同......

CRUD生成器使用@Method，这是我在初始代码中观察到的唯一区别。但这很奇怪，因为我之前也尝试过app/logs/dev.log注释并且没有任何改变（参见我的第二次编辑）......

尽管如此，我是一个非常初学的PHP和Symfony，一个全新的人，所以肯定有一些我错过的东西......但是什么呢？这时我没有想法。如果有人有线索，欢迎解释？我必须找出那种谜团的关键。

对于Profiler（默认配置），只有这个：
