制作一个连续的表格

I want to make successive form with Symfony 2.7 (2 forms) but I can not. The second form uses data from the first.

I tried this :

   if($request->getMethod() === 'POST') {
        $lot = new Lot();
        if($request->request->has('logiciel_version_debut_form')) {
            /*
                SEND FIRST VALUE FORM
            */
            $lot->setDateDebut(new \DateTime($request->get('logiciel_version_debut_form')['date_debut']['year'] . '-' . $request->get('logiciel_version_debut_form')['date_debut']['month'] . '-' . $request->get('logiciel_version_debut_form')['date_debut']['day']));
        }
        /*
            SECOND FORM FORM
        */
        $form = $this->createForm('logiciel_lot_form', $lot);
        $this->submit($form);
        if ($form->handleRequest($request)->isValid()) {
            /*
                OK GOOD :-)
            */
        }
    } else {
        /*
            FIRST FORM
        */
        $form = $this->createForm('logiciel_version_debut_form');
        $this->submit($form);
    }
    return array(
        'form' => $form->createView(),
        'title' => 'Ajouter un nouveau lot'
    );

But it does not test if the first is valid. Can you help me ?

You can't doing what you want with autobinding handleRequest() in the same level request.

You can easily create a flow from FormType with this bundle: CraueFormFlowBundle
