Question

我有一个班级

Class SubjectSegment{ 
 /**
 *@CustomAssert\MyCitizenshipNumber()
 */ 
 private $citizenshipNumber; 
 /**
 *@CustomAssert\MyDate()
 */ 
 private $citizenshipNumberIssuedDate;
}

如果出现citizenshipNumber，我真正想做的是有效的citizenshipNumberIssuedDate ......

实现这一目标的最佳方式是什么

Answer 1

您好，您应该查看http://symfony.com/doc/current/reference/constraints/Callback.html

use Symfony\Component\Validator\Constraints as Assert;
use Symfony\Component\Validator\ExecutionContext;

/**
 * @Assert\Callback(methods={"isCitizenDateValid"})
 */

Class SubjectSegment{ 
    /**
    *@CustomAssert\MyCitizenshipNumber()
    */ 
    private $citizenshipNumber; 
    /**
    *@CustomAssert\MyDate()
    */ 
    private $citizenshipNumberIssuedDate;

    public function isCitizenDateValid(ExecutionContext $context)
    {
        //Do your validation here for your exemple :
        if(null === $this->citizenshipNumber && null === $this->citizenshipNumberIssuedDate) {
            $context->addViolationAtSubPath('citizenshipNumberIssuedDate', 'The date is required', array(), null);
        }
    }
}

Answer 2

Class SubjectSegment{   

    /**  
    *@CustomAssert\MyCitizenshipNumber()  
    */  
    private $citizenshipNumber;   

    /** 
    *@CustomAssert\MyDate(group={"is_my_citizenship_number"})  
    */   
    private $citizenshipNumberIssuedDate;

    public function getGroupSequence(){ 
        $sequence = ['SubjectSegment']; 
        if(null != $this->CitizenshipNumber){ 
          $sequence[] = 'is_my_citizenship_number'; 
        } 
        return $sequence; 
    } 
}

验证

$violations = $container->get('validator')->validate($segment = new SubjectSegmet(), null,$segment->getGroupSequence() );

Answer 3

您可以通过两种方式对其进行归档：

1）回调验证器（通过类方法验证）

2）使用class constraint validator

我建议采用第二种方式，因此您必须将验证器配置/设置为类范围，如：

/**
 * @Annotation
 */
class MyCitizenshipNumber  extends Constraint {

...

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

}

因此您可以访问所有类字段成员

请记住将验证器置于类定义之上，如：

/**
 *@CustomAssert\MyCitizenshipNumber()
 */ 
 Class SubjectSegment{ 

 private $citizenshipNumber; 

 /**
 *@CustomAssert\MyDate()
 */ 
 private $citizenshipNumberIssuedDate;
}

希望这个帮助

如果另一个属性不是空白，Symfony将验证属性
