Question

我是这个Symfony框架的新手，在实施过程中遇到了死胡同。只有在输入用户的new password时，我才需要验证confirm password和current password字段。

我尽力通过浏览这些链接来理解这个概念，

但事实证明，所使用的类已弃用或需要实体。

这两个字段的实现如下，

//if this field is filled
$builder->add('currentPassword', 'password', array('label'=>'Current Password',                                            
                                      'required'=>false,                                          
                                      'attr'=>array('class'=>'form-control'),                                           
                                      'error_bubbling' => true,
                                      'trim' => true,
                                      'mapped' => false,
                                      'label_attr'=>array('class'=>'col-sm-4 control-label')));

//These repeated fields must be filled or must be set as required
$builder->add( 'password', 'repeated', array( 'type' => 'password',                                          
                                      'required' => false,        
                                      'invalid_message' => ErrorMessages::PASSWORDS_DO_NOT_MATCH,
                                      'options' => array('attr' => array('class' => 'password-field form-control')),                                                                                   
                                      'first_options'  => array('label' => false,  
                                                                'error_bubbling' => true,
                                                                'label_attr'=>array('class'=>'col-sm-4 control-label')),
                                      'second_options' => array('label' => false,                                                                    
                                                                'label_attr'=>array('class'=>'col-sm-4 control-label'))));

我在控制器中使用了一堆if条件实现了验证，但是对于像这样的场景学习正确的验证方法会很棒。：）

谢谢

按如下方式修改您的课程

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

/**
 *
 * @Assert\Callback(methods={"passwordVerify"})
 */
class User implements UserInterface, \Serializable {
  //all your old code here
  public function passwordVerify(ExecutionContext $context)
  {
    //your controls about password fields here
    //in case of failure you can add that snippet of code
    $context->addViolationAtPath($propertyPath,'your message here', array(), null);
  }
}

当然，您必须能够访问passwordVerify函数的所有信息，并且最快的方法是在您的实体中创建字段verifyPassword，这样当您将表单与实体绑定时所有数据会在那里。

当您使用isValid()表单的方法时，该代码片段会自动调用回调方法

验证基于另一个字段
