本文介绍如何在Magento中直接调用产品分类，提供了从核心文件中获取分类信息的方法，并附带示例代码，演示了如何递归地加载和打印所有分类及其属性。

如果希望直接调用Magento的分类，可以参考下

 
        /app/code/core/Mage/Catalog/Block/Navigation.php

这里有Magento相关的函数可以调用，

或者也可以通过自己写些代码获取Magento所有分类，示例代码如下：

 
        function nodeToArray(Varien_Data_Tree_Node $node){ 
       
            $result = array(); 
       
            $result['category_id'] = $node->getId(); 
       
            $result['parent_id'] = $node->getParentId(); 
       
            $result['name'] = $node->getName(); 
       
            $result['is_active'] = $node->getIsActive(); 
       
            $result['position'] = $node->getPosition(); 
       
            $result['level'] = $node->getLevel(); 
       
            $result['children'] = array();  
       
            foreach ($node->getChildren() as  $child) 
       
            { 
       
                $result['children'][] = nodeToArray($child); 
       
            } 
       
            return $result; 
       
        } 
       
        function load_tree() { 
       
            $tree = Mage::getResourceSingleton('catalog/category_tree')->load(); 
       
            $store = 1; 
       
            $parentId = 1; 
       
            $tree = Mage::getResourceSingleton('catalog/category_tree')->load(); 
       
            $root = $tree->getNodeById($parentId); 
       
            if($root && $root->getId() == 1) 
       
            { 
       
            $root->setName(Mage::helper('catalog')->__('Root')); 
       
            } 
       
            $collection = Mage::getModel('catalog/category')->getCollection() 
       
                                                            ->setStoreId($store) 
       
                                                            ->addAttributeToSelect('name') 
       
                                                            //->addAttributeToSelect('id') 
       
                                                            ->addAttributeToSelect('is_active'); 
       
            $tree->addCollectionData($collection, true); 
       
            return nodeToArray($root); 
       
        } 
       
        function print_tree($tree,$level) { 
       
            $level ++; 
       
            foreach($tree as  $item) { 
       
            echo str_repeat("*", $level).$item['name'].'*'.$item['category_id'].""; 
       
            print_tree($item['children'],$level); 
       
            } 
       
        } 
       
        $tree = load_tree(); 
       
        print_tree($tree['children'],0);
