Symfony2 Form: unexpected "no POST parameters"

Question

I'm trying to persist an object via Symfony's Form component. It's not working.

When submitting the form, Symfony redirects me to the actual form, with the data previously submitted appearing in the url with GET method. In the Profiler, I can observe that there is "no POST parameters".

The Controller :

<?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(),
    ));
  }
}

The Type:

<?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)
        ;
    }
\\...
}

The View:

/* ... */
<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>
/* ... */

Note that I don't use validations for the moment.

The Entity I use is OK, the corresponding table has been created in my PostgreSQL DB via Symfony console, configuration of the parameters.yml is OK too. I can post these elements if needed.

So what could possibly go wrong ? Is that a problem in my Wamp installation or configuration, such as Apache concerns for example ? The fact is I have no clue where the problem is.

Please note that I'm a totally beginner in web-developping. I actually try to learn PHP as well as Symfony2.

EDITS following comments

1) Resulting HTML shows that the form resulting from the Twig render is setting the method of the form to "POST" : <form name="quest" method="post">

2) Adding @Method({"GET", "POST"}) under the @Route with use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method; didn't changed anything.

3.1) Informations about my Environment :

• Wampserver 2.5 (32 bits & PHP 5.5.12, Apache 2.4.9 )
• PostgreSQL 9.3.2
• Symfony 2.8.1, using Standard Edition + FOSUserBundle ~2.0@dev
• Working with Doctrine2
• Working logged as SuperAdmin (it's a backend form located in my /admin directory) in the dev environment (app_dev.php).

3.2) In my same environment, I've reproduced various forms shown in 3 different online tutorials (from Symfony book, from openclassrooms.com, and from dynamic-mess.com), and it all ended in this same way.

4) Just in case, I just went to restart the project, by reinstalling Symfony, with the same version and the same configuration, with the same Wampserver and PostgreSQL. I just kept an eye on preventing to miss some steps. It still does'nt work.

5) TEST of a Basic HTML form in my environment : Using a Form without a Class (without Entity)

The Controller :

<?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(),
     ));
    }
}

The View :

/* ... */

<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>

/* ... */

For this test, I used the Twig global template variable {{ app.request }}.

Before clicking the submitting button, the page show these informations :

After, the resulting page discards these informations :

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  

6) I tried the Symfony's generator for CRUD controllers and templates on my Entity, IT WORKED ! My data was sending by POST, and has been registered in database.

But that's still a huge mistery to me, since the methods generated in the Controller and the Form by Symfony are the same than the methods I manually tried before...

The CRUD generator uses @Method({"GET", "POST"}) , that's the only difference I have observed with my initially code. But it is strange, because I also tried @Methodannotations by myself before and it didn't changed nothing (see my 2nd EDIT)...

Still, I'm a very beginner with PHP and with Symfony, a totally newbie, so for sure there is something evident that I missed... But what ? At this moment I have NO IDEA. Explanations are welcome, if someone's got a clue ? I've got to figure out the key of that mistery.

7) Here's the log provided by default by Symfony2.8 in app/logs/dev.log file, from the time I initially show the form until the request is redirected :

As for the Profiler (configured by default), there's nothing more than this :

200 ::1 GET http://localhost/gowinquest/web/app_dev.php/admin/quest/add?quest%5B_token%5D=74fPFHnb4NPKfAotccGEE9T4EDCUhaEHY4w-hqViwUw&quest%5BdateEnd%5D%5Bdate%5D%5Bday%5D=1&quest%5BdateEnd%5D%5Bdate%5D%5Bmonth%5D=1&quest%5BdateEnd%5D%5Bdate%5D%5Byear%5D=2011&quest%5BdateEnd%5D%5Btime%5D%5Bhour%5D=0&quest%5BdateEnd%5D%5Btime%5D%5Bminute%5D=0&quest%5BdateStart%5D%5Bdate%5D%5Bday%5D=1&quest%5BdateStart%5D%5Bdate%5D%5Bmonth%5D=1&quest%5BdateStart%5D%5Bdate%5D%5Byear%5D=2011&quest%5BdateStart%5D%5Btime%5D%5Bhour%5D=0&quest%5BdateStart%5D%5Btime%5D%5Bminute%5D=0&quest%5BnbEnigma%5D=1&quest%5BquestCost%5D=1&quest%5BquestName%5D=test5&quest%5BrewardFinish%5D=1&quest%5BrewardFurther%5D=1&quest%5Bspeech%5D=test5
