Symfony - Form redirect - symfony

Question

I am building simple car renting app in Symfony for a programming class at my university.
On URL /search I show a form to user. Right now when the form is submitted user his /search again but different template is rendered
This is form code:
class SearchQueryType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('pickupCity', TextType::class)
->add('returnCity', TextType::class)
->add('pickupDateTime', DateTimeType::class, array(
'years' => range(2016,2017),
'error_bubbling' => true,
))
->add('returnDateTime', DateTimeType::class, array(
'years' => range(2016,2017),
'error_bubbling' => true,
))
->add('save', SubmitType::class, array(
'label' => 'Find Car',
'attr' => array(
'class' => 'btn-secondary btn-lg'
)))
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\SearchQuery',
));
}
}
And controller for this route:
class SearchController extends Controller
{
public function searchAction(Request $request)
{
$query = new SearchQuery();
$form = $this->createForm(SearchQueryType::class, $query);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
/* Some logic here */
return $this->render('AppBundle:default:results.html.twig', array(
'form' => $form->createView()
));
}
return $this->render('AppBundle:default:search.html.twig', array(
'form' => $form->createView()
));
}
}
However when the form is submitted I want to redirect to URL /results?SUBMITTED-PARMS-HERE, so user can send this link to someone and receive the same results. On /results again I wand to render form, this time filled with search params submitted and below render available car.
I don't know if its the best way to handle this problem, current solution works but link can't be send to someone else.
EDIT:
I change the code to fallowing:
if ($form->isSubmitted() && $form->isValid()) {
$data = $form->getData();
$session = $this->get('session');
$session->set('pickupCity', $data->getPickupCity());
$session->set('returnCity', $data->getReturnCity());
$session->set('pickupDateTime', $data->getPickupDateTime());
$session->set('returnDateTime', $data->getReturnDateTime());
return $this->redirectToRoute('results', array(
'pickupCity' => $data->getPickupCity(),
'returnCity' => $data->getReturnCity(),
'pickupDate' => $data->getPickupDateTime()->format('d-m-Y-H-i'),
'returnDate' => $data->getReturnDateTime()->format('d-m-Y-H-i'),
), 301);
}
So as a result I receive URL ./results/Paris/Berlin/10-02-2016-10-00/17-02-2016-10-00
And in routing.yml:
results:
path: /results/{pickupCity}/{returnCity}/{pickupDate}/{returnDate}
defaults: { _controller: AppBundle:Search:result}
methods: [POST]
Because I only want to receive POST request on this route and now when I submit form I get error page saying:
No route found for "GET /results/Paris/Berling/01-07-2016-00-00/01-11-2016-00-00": Method Not Allowed (Allow: POST)
Any idea how to fix it?
EDIT 2:
Never mind, my reasoning was bad.

Answer 1

Not sure, but maybe using this example.
$this->redirect($this->generateUrl('default', array('pickupCity' => $pickupCity, 'returnCity' => $returnCity, 'pickupDateTime' => $pickupDateTimepickupDateTime)));
With your own parameter, which you can get where you put your comment
/* Some logic here */

Answer 2

You can use getQueryString() function.
Sample:
if ($form->isSubmitted() && $form->isValid()) {
return $this->redirect('results?'.$request->getQueryString());
}
