有一些时候我们需要得到当前分类的父级分类，下面是在magento中调用父级分类的方法：
<?php
$currentCat = Mage::registry('current_category');

//if Rootcategory display current category only
//this gets around the problem of displaying DEFAULT CATEGORY
if ( $currentCat->getParentId() == Mage::app()->getStore()->getRootCategoryId() )

//Display current category
echo $this->getCurrentCategory()->getName() ;

else

{
// Display ParentCategory of Current Category
echo $this->getCurrentCategory()->getParentCategory()->getName() ;
}
?>
