Php 如何在提交后检索get请求值

我正在处理一个Symfony 3项目，并试图从控制器操作中的请求中检索一个值（

bedroomid

）

$bedroomid = $request->query->get('bedroomid');

这很好用。请注意，这是在（$form->isSubmitted（）&&&$form->isValid（））条件之前。问题是在我提交表单之后，

$request->query->get（'bedroomid'）返回空值。我需要此值将其传递给另一个操作，如下所示：

$url = $this->generateUrl('epita_housing_orders_show', array('id' => $id, 'bedroom'=>$bedroomid));
        $response = new RedirectResponse($url);
         return $response;

有什么想法吗

编辑：

以下是我的控制器操作：

/**
 * @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,
    ));
}

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,
    ));
   }

试用控制器：

if ($form->isSubmitted() && $form->isValid()) {
       $bedroom = $form->getData()->getBedroom();
 }

现在，在submitt中，您可以获得卧室值…
为什么不使用VarDumper:：dump（$request）来查看您的请求是什么样子的？您可以提供您的操作的完整代码吗？@Stephan我可以在表单提交之前获得所需的值，但不能after@Anton我编辑了这本书post@Somesh谢谢男人：）为什么不使用VarDumper:：dump（$request）要查看您的请求是什么样子的？您能提供您的操作的完整代码吗？@Stephan我可以在提交表单之前获得所需的值，但不能after@Anton我编辑了这本书post@Somesh谢谢男人：）
