Question

我一直在寻找这个答案的高低。如果有人能指出我正确的方向，我将非常感激。我想在侧边栏导航中显示子类别上的所有其他子类别。

作为一个例子......

INSTEON

INSTEON Starter Kits
INSTEON响应者
INSTEON控制器
INSTEON配饰

当选择INSTEON的子类别（以INSTEON响应者为例）时 - 我仍然希望显示其他孩子（请参阅http://www.smarthome.com.au/insteon.html）。理想情况下，现在的孩子应该是大胆的，其他孩子应该是正常的。

我相信我需要编辑app / design / frontend / theme / subtheme / template / catalog / navigation / left.phtml

只需使用

$parent_category_id = $this->getCurrentCategory()->getParentCategory()->getId();

获取父类别ID。然后

Mage::getModel('catalog/category')->load($parent_category_id);

加载整个父类别。有了它，您可以加载父类别的孩子（参见Get Child categories magento）。
