Magento：顯示所有level2類別

Question

我有4個級別的類別。
例如：
level0category --> level1category --> level2category -->lastlevel_level3cateogory
是否有可能在lastlevel上顯示僅在level2中的類別？
我在想的東西用自動分類檢測，而不必設置CAT_ID =

編輯（我加載自定義left.phtml塊上）：這就是我一直在尋找，從不同的代碼組合後源。

<?php 
    $currentCat = Mage::registry('current_category'); 

    if ($currentCat->getParentId() == Mage::app()->getStore()->getRootCategoryId()) 
    { 
     // current category is a toplevel category 
     $loadCategory = $currentCat; 
    } 
    else 
    { 
     // current category is a sub-(or subsub-, etc...)category of a toplevel category 
     // load the parent category of the current category 
     $loadCategory = Mage::getModel('catalog/category')->load($currentCat->getParentId()); 
     // @TODO enhance for more nested category levels to display sub-categories 
    }  
    $subCategories = explode(',', $loadCategory->getChildren()); 

    foreach ($subCategories as $subCategoryId) 
    { 
     $cat = Mage::getModel('catalog/category')->load($subCategoryId); 


if ($cat->getIsActive()) 
{ 
    if ($currentCat->getEntityId() == $subCategoryId) 
    { 
     echo '<li style="display:none;">'.$cat->getName().'</li>'; 
    } 
    else 
    { 


    echo '<a href="'.$cat->getURL().'">'.$cat->getName().'</a> <br>'; } 
} 

    } 
?> 

Answer 1

$categories = Mage::getModel('catalog/category') 
        ->getCollection() 
        ->addAttributeToSelect('*') 
        ->addIsActiveFilter() 
        ->addAttributeToFilter('level',2) 
        ->addOrderField('name'); 

確保這條線是有

apply ->addAttributeToFilter('level',2)
