在示例中尝试使用的短名称"验证程序加载仅在您通过验证程序插件管理器注册了该短名称/别名().

The "short name" validator loading you are attempting to use in your example only works if you register that short name / alias with the validator plugin manager (Zend\Validator\ValidatorPluginManager) first.

一种替代方法(也是我的方式)是在创建表单过滤器对象时注入必要的自定义验证器实例. ZfcUser就是这样的:

One alternative to this (and the way I do it) is to inject instances of necessary custom validators when creating the form filter object. This is the way ZfcUser does it:

// Service factory definition from Module::getServiceConfig
'zfcuser_register_form' => function ($sm) {
     $options = $sm->get('zfcuser_module_options');
     $form = new Form\Register(null, $options);
     $form->setInputFilter(new Form\RegisterFilter(
         new Validator\NoRecordExists(array(
             'mapper' => $sm->get('zfcuser_user_mapper'),
             'key'    => 'email'
         )),
         new Validator\NoRecordExists(array(
            'mapper' => $sm->get('zfcuser_user_mapper'),
            'key'    => 'username'
         )),
         $options
     ));
     return $form;
},

在此，将两个ZfcUser\Validator\NoRecordExists验证器实例(一个用于电子邮件，一个用于用户名)注入到注册表单(ZfcUser\Form\RegisterFilter)的输入过滤器对象的构造函数中.

Here, the two ZfcUser\Validator\NoRecordExists validator instances (one for email and one for username) are injected into the constructor of the input filter object for the registration form (ZfcUser\Form\RegisterFilter).

然后，在ZfcUser\Form\RegisterFilter类内部，将验证器添加到元素定义中:

Then, inside the ZfcUser\Form\RegisterFilter class, the validators are added to the element definitions:

$this->add(array(
    'name'       => 'email',
    'required'   => true,
    'validators' => array(
        array(
            'name' => 'EmailAddress'
        ),
        // Constructor argument containing instance of the validator
        $emailValidator
    ),
));

我相信另一种选择是使用完全限定的类名作为验证器名称(即:"User \ Validator \ PasswordStrength"，而不只是"PasswordStrengthValidator")，尽管我从未尝试过这样做.

I believe another alternative is to use the fully-qualified class name as the validator name (ie: "User\Validator\PasswordStrength" instead of just "PasswordStrengthValidator"), though i've never attempted this myself.
