我目前正在开发具有多个网站和商店视图的Magento安装。我正在尝试重新设计四个子网站中的一个。
添加了一个自定义模块，它似乎重写/扩展默认的顶部导航菜单以自动包含CMS页面并向菜单添加横幅广告位。问题是我想恢复单个网站视图的默认Magento顶级菜单（即没有CMS页面）。
我已经尝试禁用系统内的模块 - ＆gt;配置 - ＆gt;高级 - ＆gt;该网站的高级，但这似乎使整个顶部导航消失。我相信我要删除的功能是：

我知道这个模块的配置文件如下所示：
<?xml version="1.0"?>
<config>
<modules>
<Fvzzy_Category>
<version>0.1.0</version>
</Fvzzy_Category>
</modules>
<global>
<blocks>
<fvzzy_category>
<class>Fvzzy_Category_Block</class>
</fvzzy_category>
<catalog>
<rewrite>
<navigation>Fvzzy_Category_Block_Navigation</navigation>
</rewrite>
</catalog>
</blocks>
<resources>
<fvzzy_category_setup>
<setup>
<module>Fvzzy_Category</module>
<class>Mage_Catalog_Model_Resource_Eav_Mysql4_Setup</class>
</setup>
</fvzzy_category_setup>
</resources>
</global>
</config>
如果我能够从该文件中删除以下部分，我会得到我想要的结果：
<catalog>
<rewrite>
<navigation>Fvzzy_Category_Block_Navigation</navigation>
</rewrite>
</catalog>
问题是，我只想让顶部导航菜单功能恢复正常，以便一个网站视图。
我尝试完全复制模块，禁用原始模块并在我想要的网站中启用新模块，但这也似乎使顶部菜单完全消失。
我真的不确定还有什么可以做的 - 如果有人能够提供帮助，我将非常感激。
非常感谢。

如果您希望此扩展程序仍然适用于您的Magento应用程序，则禁用该扩展程序将不会产生预期结果。
在这种情况下，你可以做两件事
使用您的模块覆盖此自定义扩展程序并根据需要进行更改
注释掉定义核心块覆盖的配置部分。你已经尝试过它了
还有另一种选择。您可以在重写块类中进行条件检查。这种情况检查有点像这样。
if(Mage::app()->getStore()->getCode()== 'website_code_for_sub_site'){
//execute existing code
}
此方法确保仅在具有代码website_code_for_sub_site的网站正在查看时才会执行在重写块类内定义的方法。
希望有所帮助
