问题
Im working on a project where I'm using some Symfony Components. My problem is how to make the Form Component's validation of Forms use AnnotationMapping to find the constraints.
SetUp:
global $loader; //composer - autoload
AnnotationRegistry::registerLoader([$loader, 'loadClass']);
$validator = Validation::createValidatorBuilder()
->enableAnnotationMapping()
->getValidator();
$formFactory = Forms::createFormFactoryBuilder()
[...]
->addExtension(new ValidatorExtension($validator))
->getFormFactory();
Entity
/**
* @ORM\Entity
* @ORM\Table(name="..")
*/
class Conductor extends AbstractEntity {
/**
* @ORM\Id
* @ORM\Column(type="integer")
* @ORM\GeneratedValue
*/
protected $id;
/**
* @Assert\NotBlank()
* @ORM\Column(type="string")
*/
protected $pattern;
[...]
}
Building the Form
$builder = $App->getFormFactory()->createBuilder(FormType::class, $entity_data);
foreach ($fields as $field) {
$builder->add(
$field,
null,
[
"attr" => array("class" => "..."),
]
);
}
$builder->getForm();
FormSubmit / Validation
if($request->isMethod('POST')) {
$formTable = $this->createFormTable( array() );
$form = $formTable->buildForm($entity);
$form->submit($this->dataMapper->formDataFromPost());
/*
$entity = $this->dataMapper->mapFromPost();
$validator = Validation::createValidatorBuilder()
->enableAnnotationMapping()
->getValidator();
*/
if($form->isValid()) {
[...]
} else {
[...]
}
}
Im trying to make the NotBlank() Constraints work. But my form passes the validation in any case. If I use a new validator and validate with it, it will show me the correct Errors. But the Form->isValid() function does not. Maybe it is not configured correctly to use AnnotationMapping? Thank you very much in advance for tipps or solutions!
Problem localization
The form handleRequest / submit and validation are working as expected!
The form does not have any constraints!! -> Mapping the Constraints from Annotation is not happening / working.
I did find a similar question: Why does Symfony form not validate my DTO with constraint annotations?
回答1:
I wasn't able to find a solution to enable the mapping that should happen inside the FormComponent with the ValidatorExtension.
But I did find a functional workaround. My approach is to get the Constraints from the readPropertyMetadata function of the validator:
use Symfony\Component\Validator\Validation;
public function buildForm(AbstractEntity $entity) {
$validator = Validation::createValidatorBuilder()
->enableAnnotationMapping()
->getValidator();
$fields = [*ENTITY PRPERTIES*];
$classMeta = $validator->getMetadataFor($entity);
foreach ($fields as $field) {
$metadata = $classMeta->getPropertyMetadata($field);
if(is_array($metadata) && count($metadata) > 0) {
$constraints = $classMeta->getPropertyMetadata($field)[0]->constraints;
} else {
$constraints = [];
}
$builder->add(
$field,
null,
[
"attr" => array("class" => "..."),
"constraints" => $constraints
]
);
}
}
As now the constraints are added to the form the validation finally works as expected.
