我正在研究一个Symfony 3项目，我正试图从像这样的控制器动作中的请求中检索一个值（bedroomid）
$bedroomid = $request->query->get('bedroomid');
工作正常。请注意，这是在if ($form->isSubmitted() && $form->isValid())条件之前。问题是在我提交表单后，$request->query->get('bedroomid');返回空值。我需要这个值将它传递给另一个这样的动作：
$url = $this->generateUrl('epita_housing_orders_show', array('id' => $id, 'bedroom'=>$bedroomid));
$response = new RedirectResponse($url);
return $response;
有什么想法吗？
修改
这是我的控制器动作：
/**
* @Route("/booking/{id}", requirements={"id" = "\d+"}, name="studentbooking")
*/
public function studentBookingAction(Request $request, $id) {
$em = $this->getDoctrine()->getManager();
$user = $this->get('security.token_storage')->getToken()->getUser();
$role = $user->getRoles()[0];
$listing = $em->getRepository('EpitaHousingBundle:Listing')->findOneBy(array('id'=>$id));
$booking = new Booking($em, $id);
$form = $this->createForm(BookingType::class, $booking);
$form->handleRequest($request);
$bedroomid = $request->query->get('bedroomid');
$selectedbedroom = $em->getRepository('EpitaHousingBundle:Bedroom')->findOneBy(array('id'=>$bedroomid));
if ($form->isSubmitted() && $form->isValid()) {
if ($listing->getPropertytype()->getId() == 1) {
$booking->setListing($listing);
$em->persist($booking);
$em->flush();
$url = $this->generateUrl('epita_housing_orders_show', array('id' => $id));
}
else {
$booking->setBedroom($selectedbedroom);
$em->persist($booking);
$em->flush();
$url = $this->generateUrl('epita_housing_orders_show', array('id' => $id, 'bedroom'=>$bedroomid));
}
$response = new RedirectResponse($url);
return $response;
}
return $this->render('EpitaHousingBundle:Student:confirmbookingpage.html.twig', array(
'id'=>$id,
'form' => $form->createView(),
'listing' => $listing,
'bedroomid' => $bedroomid,
));
}

这是将我重定向到学生预订行动的页面：
{% if listing.propertytype.id == 1 %}
<a href="{{ path('studentbooking', {'listing':id,'id': id }) }}">
<button type="submit" name="approve" value="approve" class="btn btn-primary">Book Now</button>
</a>
{% else %}
<a href="{{ path('studentbooking', {'bedroom' : bedroom.id, 'id': id }) }}">
{# <input type="hidden" name="bedroomid" value={{ bedroom.id }}/>#}
<button type="submit" name="approve" value="approve" class="btn btn-primary">Book Now</button>
</a>
{% endif %}
更新的答案：
$form = $this->createForm(BookingType::class, $booking, array('empty_data' => $bedroomid));
在Bookingformtype中创建Hiddenfield，如下所示：
public $bedroomid;
public function __construct($bedroomid = array())
{
$this->bedroomid = $bedroomid;
}
public function buildForm(FormBuilderInterface $builder, array $options) {
$this->bedroomid = $options['empty_data'];
$builder->add('booking', HiddenType::class, array(
'data'=> $this->bedroomid,
'required' => false,
));
}
尝试控制器：
if ($form->isSubmitted() && $form->isValid()) {
$bedroom = $form->getData()->getBedroom();
}
现在提交内容你得到卧室价值......
