剛剛創建了一個形式ZF2及其給錯誤

Question

我有以下錯誤，當我有機會我的新創建的窗體：

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

這裏是我的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', 
     ), 
    )); 
} 
} 

這裏是表單模型Album.php代碼：

// 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; 
} 

這裏是堆棧跟蹤：

#13 C:\xampp\htdocs\zendtest\public\index.php(14): Zend\Mvc\Application->run()

我如何解決上述錯誤，並使模塊正常工作。 讓我知道是否需要進一步的代碼來探索這個問題。

Answer 1

我們在評論中修復了問題，但我發佈了答案，所以如果有人遇到類似問題，可能會有所幫助。

首先。檢查你的Zend庫是否是最新的。
如果是這樣，那麼嘗試檢查問題是否只有一個輸入（評論/刪除臨時）或它是全球性的問題。也許你只是在輸入類型中輸入錯誤（Zend可能會拋出給定類型不存在的異常）。

如果你過時的信息：

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

請記住，Zend公司在未來的版本將刪除getServiceLocator()方法，因此使用服務定位器控制器不推薦。你應該通過工廠類注入你的依賴關係。
