This tutorial is going to show you how to get all categories and sub categories in magento.In This script I have shown all subcategories on the basis of main category means Root Catalog’s Id.
If you change the $id = 1 then it will display suabcategory upto the first level that looks like below.
If you change the $id = 3 then it will display suabcategory upto the second level that looks like below.
So lets starts the coding part :
define('MAGENTO', realpath(dirname(__FILE__)));
require_once MAGENTO . '/app/Mage.php';
Mage::app();
$storename = 'default';
$exporter = new XmlCreateCategoryTree();
class XmlCreateCategoryTree
{
function __construct()
{
ini_set('max_execution_time', 14400);
chdir(MAGENTO);
umask(0);
$this->createCategoryTree();
}
public function createCategoryTree()
{
$id = 3;
$categories = $this->getCategories($id);
if($categories[0]['name'] != ''){
foreach($categories as $category){
echo $category['name']."\n";
$sub_categories = $this->getCategories($category['id']);
if($sub_categories[0]['name'] != ''){
foreach($sub_categories as $sub_category){
echo '---'.$sub_category['name']."\n";
$sub_sub_categories = $this->getCategories($sub_category['id']);
if($sub_sub_categories[0]['name'] != ''){
foreach($sub_sub_categories as $sub_sub_category){
echo "--- ---".$sub_sub_category['name']."\n";
}
}
}
}
}
}
}
private function getCategories($id){
$children = Mage::getModel('catalog/category')->getCategories($id);
$cat = array();
foreach ($children as $category){
$cat['name'] = $category->getName();
$cat['id'] = $category->getId();
$allCat[] = $cat;
}
return $allCat;
}
}
Or You can get the categories tree by another method means by collecting all ids from catalog model.
$_category = Mage::getModel('catalog/category');
$treeModel = $category->getTreeModel();
$treeModel->load();
$allIds = $treeModel->getCollection()->getAllIds();
$_categories = array();
if ($allIds)
{
foreach ($allIds as $id)
{
$category->load($id);
$_categories[$id]['name'] = $category->getName();
$_categories[$id]['path'] = $category->getPath();
}
foreach ($allIds as $Id)
{
$path = explode('/', $_categories[$Id]['path']);
$string = '';
foreach ($path as $pathId)
{
$string.= $_categories[$pathId]['name'] . ' >';
$cnt++;
}
$_string.= ';' . $Id ."\n";
echo $_string;
}
}
