我对自定义验证器约束有一些问题。我想验证实体 TicketCode 中的字段代码。

但是当我使用 if(form->isValid) 时没有调用验证器，我不明白为什么。

我的自定义验证器需要实体管理器与数据库检查此代码是否对应，否则验证器会发送消息错误。

我的实体

     <?php

namespace My\MyBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;
use My\MyBundle\Validator as TicketAssert;


/**
 * My\MyBundle\Entity\TicketCode
 *
 * @ORM\Table()
 * @ORM\Entity(repositoryClass="My\MyBundle\Entity\TicketCodeRepository")
 */
class TicketCode
{
    /**
     * @var integer $id
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string $code
     *
     * @ORM\Column(name="code", type="string", length=255)
     * @TicketAssert:ValidCode(entity="TicketBundle:TicketCode", property="code")
     */
    protected $code;
 }

我的班级约束

<?php

namespace My\MyBundle\Validator;

use Symfony\Component\Validator\Constraint;

/**
 * @Annotation
 */

class ValidCode extends Constraint
{
    public $message = 'Code Invalide';
    public $entity;
    public $property;

    public function ValidatedBy()
    {
        return 'my_ticket_validator';
    }

    public function requiredOptions()
    {
        return array('entity', 'property');
    }

    public function targets()
    {
        return self::CLASS_CONSTRAINT;
    }
}

我的验证器

<?php

namespace My\MyBundle\Validator;

use Doctrine\ORM\EntityManager;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;


class ValidCodeValidator extends ConstraintValidator
{

    private $entityManager;

    public function __construct(EntityManager $entityManager)
    {
        $this->entityManager = $entityManager;
    }

    public function isValid($value, Constraint $constraint)
    {
        $todayInObject = new \DateTime();  //Renvoit la date du jour
        var_dump($todayInObject);

        $ticketCode = $this->entityManager->getRepository('MyMyBundle:TicketCode')->findOneBy(array('code' => $constraint->property));

        if ($ticketCode != null) {

            if ($ticketCode->nbMaxUse != 0 && ($todayInObject >= $ticketCode->getDateBegin && $todayInObject <= $ticketCode->getDateEnd())) {

                return true;
            }
            else {
                $this->setMessage($constraint->message);
                return false;
            }
        }
        else {
            $this->setMessage($constraint->message);
            return false;
        }

        return false;
    }
}

最后我的service.yml在我的包中。

parameters:

    my_ticket.validator.validcode.class:      My\MyBundle\Validator\ValideCodeValidator

services:

    my_ticket.validator.validcode:
       class:      %my_ticket.validator.validcode.class%
       arguments: [@doctrine.orm.entity_manager]
       tags:
            - { name: validator.constraint_validator, alias: my_ticket_validator }

如果您知道为什么我的验证器从未被调用，请向我解释谢谢。

您的函数名称ValidatedBy()中有一个大V。它应该是validBy()。
