获取Magento所有分类的代码

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'].'*'.$item['category_id']."<br>";
    print_tree($item['children'],$level);
    }
}
 
$tree = load_tree();
print_tree($tree['children'],0);
