Je rencontre une erreur de validation "selected options is invalid" lors de la soumission d'un formulaire Symfony avec un champ de tags à autocomplétion.
Ma configuration :
- Champ
TagAutocompleteField
- Multiple: true, choice_value: 'slug'
- EventSubscriber pour créer dynamiquement les nouveaux tags
Problème :
Malgré la bonne mise à jour des données dans le subscriber, la validation échoue.
Code :
// EventSubscriber
public function onFormPreSubmit(PreSubmitEvent $event): void
{
if (!isset($event->getData()['tags'])) {
return;
}
/** @var list<string> $incomingTags */
$incomingTags = $event->getData()['tags'] ?? [];
/** @var Tag[] $newTags */
$newTags = [];
$existingTags = $this->tagRepository->findExistingTagBySlugList($incomingTags);
$existingTagsSlug = array_map(function ($v) {
return $v->getSlug();
}, $existingTags);
foreach ($incomingTags as $t) {
if (!in_array($t, $existingTagsSlug)) {
$tag = (new Tag())->setTitle($t);
$this->em->persist($tag);
$newTags[] = $tag;
}
}
$this->em->flush();
// Combine existing and new tags
$allTags = [...$existingTags, ...$newTags];
// Update the form data with the complete list of tags
$newFormData = $event->getData();
$newFormData['tags'] = array_map(function ($tag) {
return $tag->getSlug();
}, $allTags);
$event->setData($newFormData);
// Set the normalized data (actual Tag objects)
$event->getForm()->get('tags')->setData($allTags);
}
//TagAutocompleteField
#[AsEntityAutocompleteField]
class TagAutocompleteField extends AbstractType
{
public function configureOptions(OptionsResolver $resolver): void
{
$resolver->setDefaults([
'class' => Tag::class,
'choice_label' => 'title',
'choice_value' => 'slug',
'attr' => [
'data-tags' => 'true'
],
'tom_select_options' => [
'create' => true,
],
'multiple' => true,
'required' => false,
'autocomplete' => true,
'searchable_fields' => ['title'],
'choice_lazy' => true
]);
}
public function getParent(): string
{
return BaseEntityAutocompleteType::class;
}
}
//Form
public function buildForm(FormBuilderInterface $builder, array $options): void
{
/** @var User $user */
$user = $this->security->getUser();
$editing = $builder->getForm()->getData()?->getId() !== null;
$builder
->add('title', null, [
'label' => 'Titre de l\'article',
])
