Symfony4 - change single parameter in url after submitting form

Question

I have a route that looks like this - route/{parameter} and I need to change the parameter after submitting a form.

I tried to use redirectToRoute but it created new URL together with some other parameters that the form passed which I don't want.

So I would love to ask you if there is some way to redirect to a new URL with the only parameter that I choose through select in the form.

Thank you very much for your responses.

EDIT:

I am going to share more actual information. This is how my controller for the form looks like:

$form = $this->createFormBuilder()
    ->setMethod("get")
    ->add('category', ChoiceType::class, [
        'choices' => [
            'Všechny kategorie' => 'vsechny-kategorie',
            'Automobilový průmysl' => 'automobilovy-prumysl',
            'Stavebnictví' => 'stavebnictvi',
            'Elektronika a elektrotechnika' => 'elektronika-a-elektrotechnika',
            'Gastronomie' => 'gastronomie',
            'Lesnictví' => 'lesnictvi',
            'Potravinářský průmysl' => 'potravinarsky-prumysl',
            'IT technologie' => 'it-technologie',
            'Logistika' => 'logistika',
            'Strojírenství' => 'strojirenstvi',
            'Zdravotnictví' => 'zdravotnictvi'
        ],
        'label' => 'Kategorie:'
    ])
    ->add('send', SubmitType::class, ['label' => 'Test'])
    ->getForm();

$form->handleRequest($request);

if($form->isSubmitted() && $form->isValid()) {
    $data = $form->getData();
    $category = $data['category'];

    return $this->redirectToRoute('jobs', [
        'jobs' => $pagination,
        'categoryForm' => $form->createView(),
        'category' => $category,
    ]);
}

Are you trying to dynamically change the form's endpoint before the POST action or are you trying to change the redirection of the user after the endpoint has processed the form? — Dylan Pierce

@DylanPierce I'm making a filtration for a list. The filtration works fine but I need to write the name of the category that is used as a filter in the URL so it looks for example like this domain.com/list/category — Lukas Hirt

You should be able to use the redirectToRoute, but be sure to pass the parameter you're trying to dynamically set as an array:

// in your controller action:
return $this->redirectToRoute('post_form_route', ['parameter' => $parameter]);

If that's not working for you, I would double check your route definitions and make sure your route's name & expected URL parameters are passed correctly.

The problem is that it returns URL that is longer than even all the characters available for this comment. This is how the code I have:

return $this->redirectToRoute('jobs', [             'jobs' => $pagination,             'categoryForm' => $form->createView(),             'category' => $category         ]);

Hard to tell, but I would guess that one of the URL params you're passing is a very large object, but instead is supposed to be a single attribute or a small array.

I pass the parameter category and it's in the URL as it should be but then it also passes all the info about the form as a parameter, name of the form, its children, selected value ... And that's what I'm trying to prevent (unsuccessfully yet).

you can try that :

if($form->isSubmitted() && $form->isValid()) {
    $data = $form->getData();
    $category = $data['category'];

    return $this->redirectToRoute('route', [
         'parameter' => $form->getData()->getCategory()
     ]);

}

return $this->redirectToRoute('jobs', [
    'jobs' => $pagination,
    'categoryForm' => $form->createView(),
  ]);
