我一直在像这样在 Entity 类中构建我的所有验证......

class User 
{
    protected $inputFilter;

    public function getInputFilter()
    {
        if (!$this->inputFilter) {
            $inputFilter = new InputFilter();

            $factory = new InputFactory();


            $inputFilter->add($factory->createInput(array(
                'name' => 'username',
                'required' => true,
                'filters' => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    array(
                      'name' =>'NotEmpty', 
                        'options' => array(
                            'messages' => array(
                                \Zend\Validator\NotEmpty::IS_EMPTY => 'User name can not be empty.' 
                            ),
                        ),
                    ),
                    array(
                        'name' => 'StringLength',
                        'options' => array(
                            'encoding' => 'UTF-8',
                            'min' => 4,
                            'max' => 20,
                            'messages' => array(
                                'stringLengthTooShort' => 'Please enter User Name between 4 to 20 character!', 
                                'stringLengthTooLong' => 'Please enter User Name between 4 to 20 character!' 
                            ),
                        ),
                    ),
                ),
            )));


            $inputFilter->add($factory->createInput(array(
                'name' => 'pass',
                'required' => true,
                'filters' => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    array(
                      'name' =>'NotEmpty', 
                        'options' => array(
                            'messages' => array(
                                \Zend\Validator\NotEmpty::IS_EMPTY => 'Password can not be empty.' 
                            ),
                        ),
                    ),
                    array(
                        'name' => 'StringLength',
                        'options' => array(
                            'encoding' => 'UTF-8',
                            'min' => 4,
                            'max' => 20,
                            'messages' => array(
                                'stringLengthTooShort' => 'Please enter Password between 4 to 20 character!', 
                                'stringLengthTooLong' => 'Please enter Password between 4 to 20 character!' 
                            ),
                        ),
                    ),
                ),
            ) ));            



            $inputFilter->add($factory->createInput(array(
                'name' => 'confPass',                
                'required' => true,
                'filters' => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    array(
                      'name' =>'NotEmpty', 
                        'options' => array(
                            'messages' => array(
                                \Zend\Validator\NotEmpty::IS_EMPTY => 'Confirm password can not be empty.' 
                            ),
                        ),
                    ),
                    array(
                        'name' => 'Identical',                        
                        'options' => array(
                            'token' => 'pass',
                            'messages' => array(
                                 \Zend\Validator\Identical::NOT_SAME => 'Confirm password does not match!'                             ),
                        ),
                    ),
                ),
            ) ));            


            $this->inputFilter = $inputFilter;
        }

        return $this->inputFilter;
    }
}

并在我的用户控制器中调用它。

$request = $this->getRequest();
        $user = new User();
        $form = new Loginform();
        $form->setInputFilter($user->getInputFilter());
        $form->setData($request->getPost());
        if ($form->isvalid()) {
         // success
         } else {
         // fail
         }

它一直运行良好。但现在我有一个场景，我必须检查数据库中是否已经存在用户实体所以按照丹尼尔的这个例子

我创建了一个验证器并像这样测试我的用户控制器。

        $query = 'SELECT u FROM Auth\Entity\User u WHERE u.username = :value';         
         $valid2 = new \Auth\Validator\Doctrine\NoEntityExists($this->getEntityManager(), $query);
         if($valid2->isValid("username")) {
// success
} else {
// failure
}

效果很好。

如何使用 NoEntityExists 验证器和我的其他用户名验证器在这个问题中使用上面的 inputfilter。像这样

    'validators' => array(
                        array(
                          'name' =>'NotEmpty', 
                            'options' => array(
                                'messages' => array(
                                    \Zend\Validator\NotEmpty::IS_EMPTY => 'User name can not be empty.' 
                                ),
                            ),
                        ),
    array(

    //// no Entity exist validator here
    ),

)

将 NoEntityExists 验证器放在 User 类中的问题在于，它在实体类和数据存储层之间创建了紧密耦合。使得没有Doctrine就无法使用实体类，或者不重写实体类就无法切换到新的存储层。这种紧耦合是 Doctrine 专门设计用来避免的。

需要检查数据库的验证器可以保存在自定义的 EntityRepository 类中：

class UserRepository extends \Doctrine\ORM\EntityRepository
{
    public function getInputFilter()
    {
        $inputFilter = new \Zend\InputFilter\InputFilter();
        $factory = new \Zend\InputFilter\Factory();

        $inputFilter->add($factory->createInput(array(
            'name' => 'username',
            'validators' => array(
                'name' => '\DoctrineModule\Validator\NoObjectExists',
                'options' => array(
                    'object_repository' => this,
                    'fields' => array('username'),
                ),
            ),
        )));

        return $inputFilter;
    }
}

确保向您的用户实体添加必要的注释：

/**
 * @Entity(repositoryClass="MyProject\UserRepository")
 */
class User
{
    //...
}

然后在传递给您的表单之前将输入过滤器合并在一起：

$request = $this->getRequest();
$entityManager = $this->getServiceLocator()->get('Doctrine\ORM\EntityManager');
$repository = $entityManager->getRepository('User');
$user = new User();

$filter = $repository->getInputFilter();
$filter->add($user->getInputFilter());
$form = new Loginform();
$form->setInputFilter($filter);
$form->setData($request->getPost());

if ($form->isValid()) {
    // success
} else {
    // fail
}

您是否尝试将完整的命名空间添加到验证器？

array(
    'name' =>'\Auth\Validator\Doctrine\NoEntityExists', 
    'options' => array(
        'messages' => array(
           \Zend\Validator\NotEmpty::IS_EMPTY => 'User name can not be empty.' 
        ),
    ),

),
