Magento获得全部分类代码分析_magento教程_php教程

magento获得全部的菜单分类，这段代码的好处就是可以放在任意的phtml文件中，并且做了诸多的条件判断。我们可以参考灵活运用，供初学者参考。

if you just want, like me , get all categories with hierarchy + id in order to use in datasheet

create a file “myfile.php” on the root magento folder and put the code below.
All level are marked by *. Use it as separator in excel.

<?php require_once $_SERVER['DOCUMENT_ROOT']."/app/Mage.php";
Mage::app('1');

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);
