Question

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。： - ）

Answer 1

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);

调用您的方法

Answer 2

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。： - ）

致命错误：当方法存在时，调用未定义的方法Sync_Helper_Data :: updateMagProduct（）
