Symfony: How to handle 2 forms in the same action?

Question

I have two forms that i want to handle in the same action, actually the first one works pretty good, but the other form doesn't work. This is my action code :

 /**
     * @Route("/webmaster/gestProf/{idprof}",  defaults={"idprof": 0},name="gestProf")
     * @Template()
     */
    public function gestProfAction(Request $request)
    {
        $session = new Session();
        $session->start();

        $em=$this
            ->getDoctrine()
            ->getManager();
        $repository = $em->getRepository("CNAMCMSBundle:profil");
        $profils = $repository->findAll();


        foreach ($profils as $prof) {
            $id = $prof->getId();
            $libelle = $prof->getLibelle();

        }
        $profil = new profil();
        $form = $this->createFormBuilder($profil, array('csrf_protection' => false))
            ->add('id', 'text', array('attr' => array('maxlength' => '255', 'placeholder' => 'Nouvel Identificateur', 'id' => 'id_prof')))
            ->add('libelle', 'text', array('attr' => array('maxlength' => '20', 'placeholder' => 'Nouveau Libellé', 'id' => 'libelle')))
            ->add('idprof', 'hidden', array('mapped' => false,'attr' => array('maxlength' => '20', 'placeholder' => 'Nouveau Libellé', 'id' => 'libelle')))
            ->add('Edit', 'submit', array('attr' => array('class' => 'btn btn-primary btn-block rounded_btn', 'id' => 'login_btn',
                'style' => "width:6vw;height:5vh;padding:0px 0px; position:relative;left:5vmin;top:1vmin;font-size:2vmin;")))
            ->getForm();
        $profile = new profil();
        $form2 = $this->createFormBuilder($profile, array('csrf_protection' => false))
            ->add('id', 'text', array('attr' => array('maxlength' => '255', 'placeholder' => 'Nouvel Identificateur', 'id' => 'id_prof')))
            ->add('libelle', 'text', array('attr' => array('maxlength' => '20', 'placeholder' => 'Nouveau Libellé', 'id' => 'libelle')))
            ->add('Ajouter', 'submit', array('attr' => array('class' => 'btn btn-primary btn-block rounded_btn', 'id' => 'login_btn',
                'style' => "width:6vw;height:5vh;padding:0px 0px; position:relative;left:5vmin;top:1vmin;font-size:2vmin;")))
            ->getForm();
        if ($request->request->has('form')) {
           $form->handleRequest($request);
        if ($form->isSubmitted() && $form->isValid()) {
            $data = $form->getData();
            $idprof = $form->get('idprof')->getData();
            $id = $data->getId();
            $libelle = $data->getLibelle();
            $em = $this
                ->getDoctrine()
                ->getManager();
            $repository = $em->getRepository("CNAMCMSBundle:profil");
            $profil = $repository->find($idprof);
            if ($id !== Null) {
                $profil->setId($id);
                $em->merge($profil);
                $em->flush();
            }

            if ($libelle !== Null) {
                $profil->setLibelle($libelle);
                $em->merge($profil);
                $em->flush();
            }
        }
    }
        if ($request->request->has('form2')) {
            $form2->handleRequest($request);
           // $id2 = $request->request->get('id');
           // $libelle2 = $request->request->get('libelle');
            if ($form2->isSubmitted() && $form2->isValid()) {
                $data2 = $form2->getData();
                //$idprof = $form->get('idprof')->getData();
                $id2 = $data2->getId();
                $libelle2 = $data2->getLibelle();
                $em=$this
                    ->getDoctrine()
                    ->getManager();
               $profile->setId($id2);
               $profile->setLibelle($libelle2);
                $em->persist($profile);
                $em->flush();
            }
        }

        return $this->render('CNAMCMSBundle:Default:gestProf.html.twig', array('profils'=>$profils,
            'form'=>$form->createView(),
             'form2'=>$form2->createView()

        ));
    }

And this is their implementation in Twig :

{{ form_start(form, { attr: {novalidate: 'novalidate'} }) }}
                            <section class="col-lg-9 col-md-9 col-sm-9 col-xs-9" style="position: relative; left: 5vmin;top: 6vmin">
                                <label style="display:inline-table;">
                                    <span>{{ form_widget(form.id) }}</span>
                                </label>
                            </section>
                            <section class="col-lg-9 col-md-9 col-sm-9 col-xs-9"style="position: relative; left: 5vmin;top: 6vmin">
                                <label style="display:inline-table;">
                                    <span>{{ form_widget(form.libelle) }}</span>
                                </label>
                            </section>
                            <section class="col-lg-9 col-md-9 col-sm-9 col-xs-9" style="position: relative; left: 5vmin;top: 6vmin">
                                <label style="display:inline-table;">
                                    <span>{{form_widget(form.idprof, {attr: { value : profil.id}} )}}</span>
                                </label>
                            </section>
                            <section class="col-lg-5 col-md-5 col-sm-5 col-xs-5" style="position: relative; left: 5vmin;top: 6vmin">
                                <span>{{ form_widget(form.Edit)  }}</span>
                            </section>
                            {{ form_end(form) }}


 {{ form_start(form2, { attr: {novalidate: 'novalidate'} }) }}
                <section class="col-lg-9 col-md-9 col-sm-9 col-xs-9" style="position: relative; left: 5vmin;top: 6vmin">
                    <label style="display:inline-table;">
                        <span>{{ form_widget(form2.id) }}</span>
                    </label>
                </section>
                <section class="col-lg-9 col-md-9 col-sm-9 col-xs-9"style="position: relative; left: 5vmin;top: 6vmin">
                    <label style="display:inline-table;">
                        <span>{{ form_widget(form2.libelle) }}</span>
                    </label>
                </section>
                <section class="col-lg-5 col-md-5 col-sm-5 col-xs-5" style="position: relative; left: 5vmin;top: 6vmin">
                    <span>{{ form_widget(form2.Ajouter)  }}</span>
                </section>
                {{ form_end(form2) }}

Answer 1

I solved my problem by adding the method post to my second form :

  $form2 = $this->createFormBuilder($profile,array('csrf_protection' => false))
                ->setMethod("POST");

Answer 2

First of all I'd recommend removing form classes from the controller and putting them in a separate classes under Form folder of your bundle. Then in this classes give them different prefixes to this forms.

public function getBlockPrefix()
    {
        return 'form1';
    }

Then, name all the form fields correctly and you won't have to apply data to each entity field manually. Also remove this line for both forms.

$request-request->has('form')

Why are you using $em->merge instead of persist while submitting form. Or maybe I'm missing something? Try reading this documentation. http://symfony.com/doc/current/forms.html Symfony has really great documentation.
