[Form] InvalidArgumentException while using type declaration in entity #43509
Description
Symfony version(s) affected: 5.3.4
Description
I use PHP 8 and my entities use the type declaration on setter and getter.
When validating a Form with a null value on a field that require non null (eg: method(string $value)), the handle() method throw an InvalidArgumentException and a TypeError.
How to reproduce
Example Entity, Form and Controller
src/Entity/Structure.php
<?php
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
namespace App\Entity;
/**
* @ORM\Entity()
*/
class Structure {
/**
* @ORM\Id()
* @ORM\GeneratedValue()
* @ORM\Column(type="integer")
*/
private $id;
/**
* @ORM\Column(type="string", length=255)
* @Assert\NotBank()
*/
private $name;
public function getId(): ?int
{
return $this->id;
}
public function getName(): ?string
{
return $this->name;
}
public function setName(string $name): self
{
$this->name = $name;
return $this;
}
}src/Form/StructureType.php
<?php
namespace App\Form;
use App\Entity\Structure;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class StructureType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('name')
;
}
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults([
'data_class' => Structure::class,
]);
}
}src/Controller/Structure.php
<?php
namespace App\Controller;
use App\Entity\Structure;
use App\Form\StructureType;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\Annotation\Route;
class StructureController extends AbstractController
{
#[Route('/test_form', name: 'test_form')]
public function create(Request $request): Response
{
$structure = new Structure();
$form = $this->createForm(StructureType::class, $structure);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
/* ... */
}
return $this->render('structure/form.html.twig', [
'form' => $form->createView(),
]);
}
}Possible Solution
Catch these exceptions and add a validation error asking a non null value (or use the existing Validator on the field)
Additional context
