我正在创建一个Magento扩展，我在其中使用自定义Helper类来重用我的控制器函数中的一些方法。一切都很好，直到我在助手类中添加了一个新方法。
我称之为此方法，我收到此错误：
Fatal error: Call to undefined method Art_Sync_Helper_Data::updateMagProduct() in /home/vagrant/apps/default/app/code/local/Art/Sync/controllers/ProductUpdateController.php on line 259
这就是这一行：
$product_id = self::$helperData->updateMagProduct($product);
但我已经在我的控制器顶部定义了它：
private static $helperData;
在我的indexAction（）方法中： （发生错误的方法相同。（$ product_id = self :: ....））
self::$helperData = Mage::helper('sync/data');
我想，我帮助班的功能不正确，但似乎没问题......
public static function updateMagProduct($product)
{// code...}
实际上，我之前添加的所有方法都在工作......
我还试图添加一个返回一个简单String的新方法，但这也行不通。
所以，我的问题，你知道会出现什么问题吗？ 您可以在Magento / Zend帮助程序类中使用的函数有限制吗？

===更新2 ===
我想我找到了。现在，我需要解决它
如果我Cmd +点击方法helperData，我得到以下屏幕：
Choose Declaration:
- helperData Art_Sync_ProductUpdateController .../includes/src/Art/Sync/Controllers
- helperData Art_Sync_ProductUpdateController .../app/code/local/Art/Sync/controllers
但是，我怎么能强迫一个宣言呢？
（如果我点击其中一个声明，它会在同一个班级中打开。）
===更新3：已解决===
好。我的代码中的一切都很好
我必须在Magento中停用Compilation ...现在，它正在运行，没有错误。 ： - ）
答案 0 :(得分：0)
您是否在config.xml中定义了帮助程序？像下面的东西;
...
<global>
<helpers>
<sync>
<class>Art_Sync_Helper</class>
</sync>
</helpers>
</global>
...
尝试使用Mage::helper('sync')->updateMagProduct($product);

确定。我的代码中的一切都很好。
我必须停用Compilationin Magento ......现在，它正在运行，没有错误。 ： - ）
