How to retrieve specific values in my form ? Symfony 6.0.2-CodePudding

CodePudding user response：

can you show the controller code? Otherwise try to use the form in GET and then use the Request object to get the last value entered. Exp:

{{ app.request.query.get('bigcity.name') }}

EDIT By default, a form will be submitted via an HTTP POST request to the same URL under which the form was rendered. Change the method of your form in SearchType.php

//SearchType.php
...
    public function configureOptions(OptionsResolver $resolver): void
    {
        $resolver->setDefaults([
            'data_class' => null,
            'method' => 'GET'
        ]);
    }

Or in Controller

//EventsController.php
$form = $this->createForm(SearchType::class, $data, ['method' => 'GET']);

Or in your template

//search.html.twig
{{ form_start(form, {'method': 'GET'}) }}

EDIT 2 After changing the submission method, change this

//In template(search.html.twig)
...
app.session.get('bigcity.name')
...

to this

...
app.session.get('data').bigcity.id
...

You should pass Request object in form entity

public function search(Request $request, SessionInterface $sessionInterface)
{   
    //$data = $request->query->all();
    $sessionFormData  = $sessionInterface->get('data');

    $form = $this->createForm(SearchType::class, $request);
    $form->handleRequest($request);
    
    if ($form->isSubmitted() && $form->isValid()) {
        $data = $form->getData();
        $sessionInterface->set('data', $data);
        return $this->render('front/events.html.twig', $data);
    }

    return $this->renderForm('front/search.html.twig', [
        'form' => $form
    ]);
}

And in twig file just mention fields

{{ form_start(form) }}
    <p>Où souhaites-tu faire une sortie ou une activité ?</p>
    {{ form_widget(form.bigcity, {'attr' : {'class' : 'mb-3'}} ) }}
    <p>Quel type de sortie ou d’activité t’intéresse ?</p>
    {{ form_widget(form.category, {'attr' : {'class' : 'mb-3'}} ) }}
    {{ form_widget(form.save, {'label': 'Je valide', 'attr' : {'class' : 'btn'}} ) }}
{{ form_end(form) }}
