Magento : Fatal error: Class 'Mage_Giftcards_Helper_Data' not found in ...../app/Mage.php on line 546

Muk*_*nki 4 php magento

I have installed one module extension which throws an fatal error "Fatal error: Class 'Mage_Giftcards_Helper_Data' not found in ..../app/Mage.php on line 546" in admin.

I have reffered this link /sf/answers/643390051/ and this link as well https://magento.stackexchange.com/a/7133/3693

But I have 

<global>
<helpers>
        <giftcards>
            <class>Webtex_Giftcards_Helper</class>
        </giftcards>
    </helpers>
</global>

in my config.xml and I have this class 

class Webtex_Giftcards_Helper_Data extends Mage_Core_Helper_Data{
// my methods
}
Run Code Online (Sandbox Code Playgroud)

declared at "/app/code/local/Webtex/Giftcards/Helper/Data.php" path.

I have disabled compiler and cleared cache by making empty "var/cache" directory.

I found everwhere that config.xml should have helper class define and Data.php should have declare that helper class.

但是在我的情况下我有两个,这个错误的原因是什么？我已经在我的新鲜magento安装上测试了该模块,

Magento版本是1.7.0.2

请提供此错误的帮助?? 如果有类名冲突,我们怎么调试？

更新:这是我的app/etc/modules/Webtex_Giftcards.xml文件.

谢谢

我的答案与@Pedram Behroozi的答案非常相似,如果不是因为评论的声誉上有限,我可能会将其添加为评论.

当我遇到这个问题时,是因为对adminhtml.xml中"module"属性的混淆.

<config>
  <menu>
    <catalog>
      <children>
        <productfeed translate="title" module="productfeed">
          <title>Product Data Feed</title>
          <action>adminhtml/productfeed/</action>
          <sort_order>90</sort_order>
        </productfeed>
      </children>
    </catalog>
  </menu>
</config>

当他说模块名称必须是小写且没有命名空间时,Pedram并不完全正确.当您提供"translate"属性时,相应的"module"属性会告诉Magento该转换使用什么帮助器.因此,重要的是它与config.xml中helpers节点内的节点名称完全匹配.我错了,因为在那个节点我已经包含了命名空间:

<config>
  <global>
    <helpers>
      <etw_productfeed>
        <class>Etw_Productfeed_Helper</class>
      </etw_productfeed>
    </helpers>
  </global>
</config>

在Alan Storm的文章"Admin Hello World Revisited"中,您可以看到他在模块引用中使用了名称空间,这仍然有效.所以无论哪种方式都可以,只要adminhtml.xml中的内容与config.xml中的内容匹配即可.

  • 请记住这一点,这适用于模块中的所有配置文件:即`adminhtml.xml`,`system.xml`和`widget.xml` (2认同)
