Question

我有一个包含多个日期字段的表单。我需要检查一下eventStop＆lt; eventStart（日期字段）。如果它是真的，$form->isValid()应该停止脚本并在页面上放置错误。所以根据 http://symfony.com/doc/current/cookbook/validation/custom_constraint.html#constraint-validators-with-dependencies 我已经创建了新的自定义验证约束，但是当我提交表单时，我的验证不会执行，脚本会跳过它...

我的代码： MyBundle \验证\约束\ 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 \验证\约束\ 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;
    }

您需要在验证定义中添加验证组，如下所示：

MyBundle \实体\ 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 {
