Php 使用zend framework2的回调验证器进行zend表单验证时无效

我在验证元素的值数组时遇到问题。我搜索了很多，找到了一个回调函数来验证数据

下面是我正在使用的验证代码，但它不起作用

  <?php
   namespace Tutorials\Form;

   use Zend\InputFilter\Factory as InputFactory;     // <-- Add this import
   use Zend\InputFilter\InputFilter;                 // <-- Add this import
   use Zend\InputFilter\InputFilterAwareInterface;   // <-- Add this import
   use Zend\InputFilter\InputFilterInterface;  
   use Zend\Validator\Callback;
   use Zend\I18n\Validator\Alpha;


  class AddSubTopicFilterForm extends InputFilter implements InputFilterAwareInterface  {
     protected $inputFilter;    
     public $topicData;
     public $subTopicData;

     function __construct($data = array()) {

        $articles = new \Zend\InputFilter\CollectionInputFilter();
        $articlesInputFilter = new \Zend\InputFilter\InputFilter();
        $articles->setInputFilter($articlesInputFilter);

        $this->add(new \Zend\InputFilter\Input('title'));        
        $this->add($articles, 'articles');
        if(!empty($data['data']['topic_name'])) {
           $this->topicData = $data['data']['topic_name'];
        }
       if(!empty($data['data']['sub_topic_name'])) {
         $this->subTopicData = $data['data']['sub_topic_name'];
       }
    }
    public function setInputFilter(InputFilterInterface $inputFilter){
      throw new \Exception("Not used");
    }

我注意到的第一件事是，两个回调都缺少要验证的值。这两个签名都是function（）use（），通常情况下，为了进行验证，应该是function（$itemToBeValidated）use（）。您是否试图执行验证范围之外的操作？否。当我将表单字段数据作为数组传递时，我将使用类似函数（$formFieldData），然后它将给出未定义的变量$formFieldData。。因此，我使用use（$formFieldData）传递了它。
