Symfony 3 : Adding checkboxes to form form database - forms

Question

I'm struggling with symfony forms. I want to build a form for an user. This user as a arraycollection field that gather products (nom, description).
I would like to create a form that create a checkbox for each of the products passed to the form builder. Actually it just created input fields without labels... Here is the code of my UserType class :
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('nom')->add('prenom')->add('mail')->add('tel1')->add('tel2', TextType::class, array('required' => false))
->add('username')->add('password', PasswordType::class)
->add('groupe', ChoiceType::class, array(
'choices' => array('Administrateur' => 'ROLE_SUPER_ADMIN', 'Gérant' => 'ROLE_ADMIN', 'Opérateur' => 'ROLE_USER'),
'expanded' => true,
))
->add('produits', CollectionType::class, array(
'entry_type' => ProduitType::class
))
;
}
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => User::class
));
}
/**
* {#inheritdoc}
*/
public function getBlockPrefix()
{
return 'gestcoupons_userbundle_user';
}
Here is my ProduuctType code :
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('nom')->add('prenom')->add('mail')->add('tel1')->add('tel2', TextType::class, array('required' => false))
->add('username')->add('password', PasswordType::class)
->add('groupe', ChoiceType::class, array(
'choices' => array('Administrateur' => 'ROLE_SUPER_ADMIN', 'Gérant' => 'ROLE_ADMIN', 'Opérateur' => 'ROLE_USER'),
'expanded' => true,
))
->add('produits', CollectionType::class, array(
'entry_type' => ProduitType::class
))
;
}
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => User::class
));
}
/**
* {#inheritdoc}
*/
public function getBlockPrefix()
{
return 'gestcoupons_userbundle_user';
}
Here is my UserController code :
public function ajouterAction(Request $request){
$this->denyAccessUnlessGranted('ROLE_ADMIN', null, 'Unable to access this page!');
$em = $this->getDoctrine()->getManager();
$produits = $em->getRepository('ProduitBundle:Produit')->findAll();
$societes = $em->getRepository('SocieteBundle:Societe')->findAll();
$user = new User();
foreach ($produits as $produit) {
$user->getProduits()->add($produit);
}
$form = $this->createForm('GestCoupons\UserBundle\Form\UserType', $user);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($user);
$em->flush($user);
return $this->redirect('dashboard_admin');
}
return $this->render('user/new.html.twig', array(
'user' => $user,
'form' => $form->createView(),
));
}
Thanks ahead for your help.

Answer 1

You should use Symfony\Bridge\Doctrine\Form\Type\EntityType instead of CollectionType.
In your UserType
use Symfony\Bridge\Doctrine\Form\Type\EntityType;
use AppBundle\Entity\Produit;
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('nom')
->add('prenom')
->add('mail')
->add('tel1')
->add('tel2', TextType::class, array(
'required' => false
))
->add('username')
->add('password', PasswordType::class)
->add('groupe', ChoiceType::class, array(
'choices' => array(
'Administrateur' => 'ROLE_SUPER_ADMIN',
'Gérant' => 'ROLE_ADMIN',
'Opérateur' => 'ROLE_USER'
),
'expanded' => true,
))
->add('produits', EntityType::class, array(
'class' => Produit::class,
'multiple' => true,
'expanded' => true,
'label' => 'nom' //If you don't have a __toString method in your Produit Entity
))
;
}
/**
* {#inheritdoc}
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => User::class
));
}
/**
* {#inheritdoc}
*/
public function getBlockPrefix()
{
return 'gestcoupons_userbundle_user';
}
This way you will have a checkbox for each Product entity in your database and only the one you checked will be associated to your user
