我已按照Symfony2食谱中this recipe中的步骤创建了自定义电话限制。
约束类:
namespace Foo\Bundle\StackBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
/**
* @Annotation
*/
class Phone extends Constraint
{
public $message = 'The Phone contains an illegal character';
}
验证员类:
namespace Foo\Bundle\StackBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
/**
* @Annotation
*/
class PhoneValidator extends ConstraintValidator
{
public function validate($value, Constraint $constraint)
{
$length = strlen($value);
if (is_null($value)) {
return;
}
if ( $length > 14 || ! preg_match("/\([1-9]{2}\) [0-9]{4}-[0-9]{4}/", $value)) {
$this->context->addViolation($constraint->message, array(), $value);
}
}
}
此验证器工作正常,但我想使用Symfony2提供的Regex string constraint。
我试图在约束类中实现它:
namespace Foo\Bundle\StackBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\Constraints as Assert;
/**
* @Annotation
*/
class Phone extends Constraint
{
public $message = 'The Phone contains an illegal character';
public static function loadValidatorMetadata(ClassMetadata $metadata)
{
$metadata->addPropertyConstraint('description', new Assert\Regex(array(
'pattern' => '/\([1-9]{2}\) [0-9]{4}-[0-9]{4}/'
)));
}
}
但它给我一个致命的错误,要求我实现验证方法:
致命错误:类 Foo \ Bundle \ StackBundle \ Validator \ Constraints \ CepValidator包含 1抽象方法因此必须声明为抽象或实现 其余的方法 (Symfony的\元器件\验证\ ConstraintValidatorInterface ::验证)
但是validate方法已经在ConstraintValidator类中实现了(尽管如果实现得当,我认为loadValidatorMetadata中指示的模式应该足够了。)
有关如何实现这一目标的任何建议?
更新
似乎所有工作正常,为了使Regex约束起作用,在约束类中设置模式后,validate方法可以在验证器类中声明为空,如下所示:
namespace Foo\Bundle\StackBundle\Validator\Constraints;
use Symfony\Component\Validator\Constraint;
use Symfony\Component\Validator\ConstraintValidator;
/**
* @Annotation
*/
class PhoneValidator extends ConstraintValidator
{
public function validate($value, Constraint $constraint)
{
}
}
答案 0 :(得分:2)
CepValidator 会引发错误,而不是PhoneValidator。
你有另一个档案......
src/Foo/Bundle/StackBundle/Validator/Constraints/CepValidator.php
...缺少validate()方法。
