Magento 1.9：如何获取特定类别的子类别？

Question

我使用以下块在我的Magento CMS产品网站：

{{block type="catalog/product_list" name="catalog_list" category_id="1420" template="catalog/product/listStart.phtml"}} 

如何为（在这种情况下编号1420）在块中指定我能不能得到CATEGORY_ID的所有子类别的输出。

到目前为止，我有以下代码：

<?php 
$_category = $this->getCurrentCategory(); 
$collection = Mage::getModel('catalog/category')->getCategories($_category->entity_id); 
$helper = Mage::helper('catalog/category'); 
?> 
<div class="category-products"> 
<div id="carousel"> 
    <ul class="products-in-row"> 
     <?php $i=0; foreach ($collection as $cat): ?> 
      <li class="item"> 
       <?php echo $cat->getName();?> 
      </li> 
     <?php endforeach ?> 
    </ul> 
</div> 

我只得到了主要类别的所有子类别。

此代码可以帮助，如果你想获得每一个当前类的子类

<?php 
    $layer = Mage::getSingleton('catalog/layer'); 
    $_category = $layer->getCurrentCategory(); 
    $currentCategoryId= $_category->getId(); 
    $children = Mage::getModel('catalog/category')->getCategories($currentCategoryId); 
    foreach ($children as $category) 
    { 
     echo $category->getName(); // will return category name 
     echo $category->getRequestPath(); // will return category URL 
    } 
    ?> 

另一种方式：

<?php 
    $categoryId = 10 ; // get current category id 
    $category = Mage::getModel('catalog/category')->load($categoryId); 
    $catList = explode(",", $category->getChildren()); 
    foreach($catList as $cat) 
    { 
    $subcategory = Mage::getSingleton('catalog/category')->load($cat); 
    echo $subcategory->getName(); 
    } 
?>
