如何獲取magento中的所有3個級別類別？

Question

我想顯示所有頂級類別及其各自的2級子類別。例如 根類別（ID = 3）

-Electronics 
    --Computers 
    ---Dell 
    ---Samsung 
    ---Accer 

-Games Movies and Musics 
    --Games 
    ---Pc Games 
    ---Mobile Games 

這裏電子和遊戲電影和音樂是頂級類別 我不想顯示根類別，只能從頂級類別，即從電子和遊戲電影和音樂

Answer 1

像這樣

$category_id = 'Electronics category id' 
$children = Mage::getModel('catalog/category')->getCategories($category_id); 
foreach ($children as $category) { 
echo $category->getName(); 
} 

更新： 你可以把他們通過這樣

$category_id = 'Electronics category id'; 
    $children = Mage::getModel('catalog/category')->getCategories($category_id); 
    foreach ($children as $category) { 
     echo '<h1>'.$category->getName().'</h1>'; 
     if($category->getChildren()){ 
      $childrensChildren = $category->getChildren(); 
      foreach($childrensChildren as $ChildCategory){ 
       echo '<h2>'.$ChildCategory->getName().'</h2>'; 
      } 
     } 

    }
