Symfony submit multiple related forms - php

Question

I'm looking to create an CRUD with multiple Entites and so multiple forms. A want to create a Site, each site on creation need to have 1 adresse, each adress need 1 City, each city need 1 Country
So I have a Controller where I called my Type
/**
* #Route("admin/sites/new", name="admin.sites.new")
* #param Request $request
* #return RedirectResponse|Response
*/
public function new (Request $request)
{
$site = new Site();
$adresse = new Adresse();
$ville = new Ville();
$pays = new Pays();
$form = $this->createForm(SiteType::class, $site);
$form2 = $this->createForm(AdresseType::class, $adresse);
$form3 = $this->createForm(VilleType::class, $ville);
$form4 = $this->createForm(PaysType::class, $pays);
$form->handleRequest($request);
$form2->handleRequest($request);
$form3->handleRequest($request);
$form4->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()
&& $form2->isSubmitted() && $form2->isValid()
&& $form3->isSubmitted() && $form3->isValid()
&& $form4->isSubmitted() && $form4->isValid()){
$this->em->persist($site);
$this->em->persist($adresse);
$this->em->persist($ville);
$this->em->persist($pays);
$this->em->flush();
$this->addFlash('success', 'Site crée avec succès');
return $this->redirectToRoute('admin.sites.index');
}
return $this->render('admin/sites/create.html.twig', [
'site' => $site,
'adresse' => $adresse,
'ville' => $ville,
'pays' => $pays,
'form' => $form->createView(),
'form2' => $form2->createView(),
'form3' => $form3->createView(),
'form4' => $form4->createView(),
]);
}
and a Twig to generate the view.
<div class="row">
<div class="col s12 m12 l12">
<div class="card-panel ">
<div class="row">
{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_start(form2) }}
{{ form_widget(form2) }}
{{ form_start(form3) }}
{{ form_widget(form3) }}
{{ form_start(form4) }}
{{ form_widget(form4) }}
<button class="btn s12 m6 l3">{{ button|default('Enregister') }}</button>
{{ form_end(form) }}{{ form_end(form2) }}{{ form_end(form3) }}{{ form_end(form4) }}
</div>
</div>
</div>
</div>
My question is the next, how when i will create my Site, I could link the site_id and the address_id and so the adress_id and the city_id, the city_di and the country _id ? without separate my forms ?
I mean when I press the button the relation will be create correctly.
Thanks for you help.

Answer 1

This is how you should and could achieve this :
You should use embeded form How to Embed Forms
You simply create form types for your entities : SiteType, AdresseType, VilleType, PaysType and embed them like the following
// in SiteType
//....
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
//...
->add('adresse', AdresseType::class)
;
}
// in AdresseType
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
//...
->add('ville', VilleType::class)
;
}
// in VilleType
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
//...
->add('pays', PaysType::class)
;
}
Finally in your controller, all you have to do is to create
/**
* #Route("admin/sites/new", name="admin.sites.new")
* #param Request $request
* #return RedirectResponse|Response
*/
public function new (Request $request)
{
$site = new Site();
$form = $this->createForm(SiteType::class, $site);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()
$this->em->persist($site);
$this->em->flush();
$this->addFlash('success', 'Site crée avec succès');
return $this->redirectToRoute('admin.sites.index');
}
return $this->render('admin/sites/create.html.twig', [
'site' => $site,
'adresse' => $adresse,
'ville' => $ville,
'pays' => $pays,
'form' => $form->createView(),
]);
}
And the corresponding twig is :
<div class="row">
<div class="col s12 m12 l12">
<div class="card-panel ">
<div class="row">
{{ form_start(form) }}
{{ form_widget(form) }}
<button class="btn s12 m6 l3">{{ button|default('Enregister') }}</button>
{{ form_end(form) }}
</div>
</div>
</div>
</div>
Note that in order for it to work, you need to use cascade inside your entity doctrine metadata, like so :
/**
* #ORM\OneToOne(targetEntity="AppBundle:Adresse", cascade={"all"})
*/
private $adresse;

You should use embed forms : https://symfony.com/doc/current/form/embedded.html.
