I have a form with multiple date fields. I need to check if eventStop < eventStart (date fields). IF it's true, $form->isValid() should stop script and put errors on page. So according to http://symfony.com/doc/current/cookbook/validation/custom_constraint.html#constraint-validators-with-dependencies I've create new custom validation constraint but when I submit the form, my validation is not execute, script skips it...
My code: MyBundle\Validator\Constraints\EventFormFieldsValidator.php
namespace MyBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
use Doctrine\ORM\EntityManager;
/**
* @Annotation
*/
class EventFormFieldsValidator extends ConstraintValidator {
private $em;
public function __construct(EntityManager $em) {
$this->em = $em;
}
public function validate($object, Constraint $constraint) {
die('end'); /* just for check */
$this->context->addViolationAt('eventStart', 'There is already an event during this time!');
$this->context->addViolation('There is already an event during this time!');
}
}
MyBundle\Validator\Constraints\EventFormFields.php
namespace MyBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
/**
* @Annotation
*/
class EventFormFields extends Constraint {
public function validatedBy() {
return 'event_form_validator';
}
public function getTargets() {
return self::CLASS_CONSTRAINT;
}
}
MyBundle\Entity\Event.php
namespace MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;

}
you need to add the validation group in the validation definition as follow:
MyBundle\Entity\Event.php
namespace MyBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use MyBundle\Validator\Constraints as ValidateAssert;
/**
* @ORM\Entity
* @ORM\Entity(repositoryClass="MyBundle\Entity\EventRepository")
* @ORM\Table(name="events")
* @ValidateAssert\EventFormFields(groups={"registration"})
*
*/
class Event {
Hope this help
