Build and render a form with inheritance classes in Symfony 6 - php

Question

I have three classes (User, Professionel and Simple, where Professionel and Simple are the children of User). I use inheritance mapping like this:
#[ORM\Entity(repositoryClass: UserRepository::class)]
#[ORM\InheritanceType("JOINED")]
#[ORM\DiscriminatorColumn(name:"compte", type: "string")]
#[ORM\DiscriminatorMap(["professionnel"=>Professionel::class, "simple"=> Simple::class])]
class User implements UserInterface, PasswordAuthenticatedUserInterface
{
#[ORM\Id]
#[ORM\GeneratedValue]
#[ORM\Column(type: 'integer')]
private $id;
#[ORM\Column(type: 'string', length: 180, unique: true)]
#[Assert\NotBlank()]
#[Assert\Length(min:2, max:80)]
private $email;
#[ORM\Column(type: 'string', length: 50)]
private $typeCompte;
}
class Professionel extends User
{
private $nameProfessionel;
//getter setter
}
class Simple extends User
{
private $name;
//getter setter
}
I have generated formtype for each entity and extended SimpleType and ProfessionelType like this:
class SimpleType extends UserFormType
{
public function buildForm(FormBuilderInterface $builder, array $options): void
{
$builder
->add('name')
;
}
public function configureOptions(OptionsResolver $resolver): void
{
$resolver->setDefaults([
'data_class' => Simple::class,
]);
}
}
class ProfessionelType extends UserFormType
{
public function buildForm(FormBuilderInterface $builder, array $options): void
{
$builder
->add('nameProfessionel');
}
public function configureOptions(OptionsResolver $resolver): void
{
$resolver->setDefaults([
'data_class' => Professionel::class,
]);
}
}
What I want to do is whenever the user clicks on a radio button (Simple or Professionel), to only show the form that fits.
I have tried to build the form in the controller:
$types = [
'parentForm' => UserFormType::class,
'partForm' => SimpleType::class,
'proForm' => ProfessionelType::class,
];
$forms = [];
foreach ($types as $type1) {
$forms[] = $this->createForm($type1);
}
but I have this error :
Could not load type "App\Form\ChoiceType": class does not exist.
