刚刚使用 ZF2 创建了一个表单并给出了错误

Question

我在访问新创建的表单时遇到以下错误：

Zend\Form\Factory::create expects the $spec["type"] to implement one of Zend\Form\ElementInterface, Zend\Form\FieldsetInterface, or Zend\Form\FormInterface; received Hidden

这是我的 AlbumForm.php 文件：

 namespace Album\Form;

 use Zend\Form\Form;

 class AlbumForm extends Form
     {
 public function __construct($name = null)
 {
     // we want to ignore the name passed
     parent::__construct('album');

     $this->add(array(
         'name' => 'id',
         'type' => 'Hidden',
     ));
     $this->add(array(
         'name' => 'title',
         'type' => 'Text',
         'options' => array(
             'label' => 'Title',
         ),
     ));
     $this->add(array(
         'name' => 'artist',
         'type' => 'Text',
         'options' => array(
             'label' => 'Artist',
         ),
     ));
     $this->add(array(
         'name' => 'submit',
         'type' => 'Submit',
         'attributes' => array(
             'value' => 'Go',
             'id' => 'submitbutton',
         ),
     ));
 }
}

下面是表格的模型 Album.php 代码：

// Add content to these methods:
 public function setInputFilter(InputFilterInterface $inputFilter)
 {
     throw new \Exception("Not used");
 }

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

         $inputFilter->add(array(
             'name'     => 'id',
             'required' => true,
             'filters'  => array(
                 array('name' => 'Int'),
             ),
         ));

         $inputFilter->add(array(
             'name'     => 'artist',
             'required' => true,
             'filters'  => array(
                 array('name' => 'StripTags'),
                 array('name' => 'StringTrim'),
             ),
             'validators' => array(
                 array(
                     'name'    => 'StringLength',
                     'options' => array(
                         'encoding' => 'UTF-8',
                         'min'      => 1,
                         'max'      => 100,
                     ),
                 ),
             ),
         ));

         $inputFilter->add(array(
             'name'     => 'title',
             'required' => true,
             'filters'  => array(
                 array('name' => 'StripTags'),
                 array('name' => 'StringTrim'),
             ),
             'validators' => array(
                 array(
                     'name'    => 'StringLength',
                     'options' => array(
                         'encoding' => 'UTF-8',
                         'min'      => 1,
                         'max'      => 100,
                     ),
                 ),
             ),
         ));

         $this->inputFilter = $inputFilter;
     }

     return $this->inputFilter;
 }

这是堆栈跟踪：

如何解决上述错误并使模块正常工作。让我知道是否需要任何进一步的代码来探索这个问题。

Answer 1

我们在评论中解决了问题，但我 post 回答了，所以如果有人有类似的问题，它可能会有所帮助。

首先。检查您的 Zend 库是否是最新的。
如果是这样，则尝试检查问题是否仅与某个特定输入有关（comment/remove 临时）还是全局问题。也许您只是在输入类型中输入了错误（Zend 可能会抛出给定类型不存在的异常）。

如果您收到已弃用的信息：

You are retrieving the service locator from within the class [...]

请记住，未来版本的 Zend 将删除 getServiceLocator() 方法，因此不推荐在控制器中使用服务定位器。您应该通过工厂 class.
