Querying with the Query Builder - web

Question

I'M USING SYMFONY 4.12 I'm trying to write queries to filter my jobs(I've job table ,départements one) I first try with experience but I'm stuck in
here is my offerController:
/**
* #Route("/offres", name="offres")
* #param Request $request
* #param PaginatorInterface $paginator
* #param FormFactoryInterface $formFactory
* #return Response
*/
public function offreSearch(Request $request, PaginatorInterface $paginator ,FormFactoryInterface $formFactory):Response
{
$datas =new OffreEmploi();
$formFilter=$formFactory->create(OfferFilterForm::class,$datas);
$offres = $this->repository->findSearch($datas);
$formFilter->handleRequest($request);
return $this->render('offre/index.html.twig', [
'controller_name' => 'OffreController',
'offres' => $offres,
'formulaire' =>$formFilter->createView(),
]);
}
and this is my query in the offerRepository:
public function findSearch(OffreEmploi $data):?array
{
$query = $this->createQueryBuilder('o');
if ($data->getExperience() !== null) {
$query
->where('o.experience > :experience')
->setParameter('experience', $data->getExperience());
}
return $query->getQuery()->getResult();
}
when it come to enter any number IT gives the same thing it shows all the jobs stored in the database,I don't know where the problem is.
THE RESULT

Answer 1

Try with this solution:
public function findSearch(OffreEmploi $data):?array
{
$query = $this->createQueryBuilder('o');
if (!empty($data->getExperience())
// ...
}
return $query->getQuery()->getResult();
}
If it doesn't work , try to dump $data->getExperience() to see its value
public function findSearch(OffreEmploi $data):?array
{
$query = $this->createQueryBuilder('o');
dd($data->getExperience()) ;
}
EDIT
So try to do like this but be sure you send the form with GET method not POST:
public function offreSearch(Request $request, PaginatorInterface $paginator)
{
$em = $this->getDoctrine()->getManager();
$form = $this->createForm(OfferFilterForm::class);
$form->handleRequest($request);
$data = $request->query->all();
$qb = $em->getRepository(OffreEmploi::class)->findSearch($data);
$offres = $paginator->paginate($qb, $request->query->get('page', 1), 20);
return $this->render('offre/index.html.twig', array(
'formulaire' =>$form->createView(),
'offres' => $offres,
));
}
In the formType:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('experience', IntegerType::class);
//.....
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => null,
'csrf_protection' => false,
));
}
public function getBlockPrefix()
{
return null;
}
and in the Repository:
public function findSearch($data)
{
$query = $this->createQueryBuilder('o');
if (!empty($data['experience'])) {
$query
->where('o.experience > :experience')
->setParameter('experience', $data['experience']);
}
return $query->getQuery()->getResult();
}

Answer 2

I think I found the answer but I just create another class witch contain all the form's field and that's it I don't know how it works because I didn't change significant things for that thinks for your help.
