How to get sub-categories of a specific parent category?

2023-02-15 17:37 问答作者：

I had a main category (parent 开发者_运维问答category) whose id = 10. I want to echo just its sub-categories. How can I do that?

$children = Mage::getModel('catalog/category')->getCategories(10);
foreach ($children as $category) {
    echo $category->getName();
}

This code may help if you want to get child category of every current category

    <?php 
    $layer = Mage::getSingleton('catalog/layer');
    $_category = $layer->getCurrentCategory();
    $currentCategoryId= $_category->getId();
    $children = Mage::getModel('catalog/category')->getCategories($currentCategoryId);
    foreach ($children as $category)
    {
          echo $category->getName(); // will return category name 
          echo $category->getRequestPath(); // will return category URL
    }
    ?>

Another way:

$children = Mage::getModel('catalog/category')->load(10)->getChildrenCategories();
foreach ($children as $category):
    $category = Mage::getModel('catalog/category')->load($category->getId());
    echo '<li><a href="' . $category->getUrl() . '">' . $category->getName() . '</a></li>';
endforeach;

<?php 
$parentCategoryId = 107;
$cat = Mage::getModel('catalog/category')->load($parentCategoryId);
$subcats = $cat->getChildren();

// Get 1 Level sub category of Parent category
foreach(explode(',',$subcats) as $subCatid)
              {
                $_category = Mage::getModel('catalog/category')->load($subCatid);
  if($_category->getIsActive()) {
    echo '<ul><a href="'.$_category->getURL().'" title="View the products for the "'.$_category->getName().'" category">'.$_category->getName().'</a>';
   echo '</ul>';
  }
}

?>

If you want 2 level , 3 Level, 4 Level or n Level subcategories of parent category than Click Here

This is my solution

<?
    // Project  : 
    // File     :
    // Author   : Hidayet Ok ( hidonet@gmail.com )

    require_once('./app/Mage.php');
    Mage::app("default");

    $rootcatId  = Mage::app()->getStore()->getRootCategoryId();
    $root_cat   = Mage::getModel('catalog/category')->load($rootcatId);

    $categories = get_child_categories($root_cat);

    echo "<pre>";
    print_r($categories);
    echo "</pre>";


    function get_child_categories($parent) {

        $cat_model = Mage::getModel('catalog/category');

        $categories = $cat_model->load($parent->getId())->getChildrenCategories();

        $ret_arr = array();
        foreach ($categories as $cat) 
        {
            $ret_arr[] = array(
                                'cat_id' => $cat->getId(),
                                'cat_name' => $cat->getName(),
                                'cat_url' => $cat->getUrl(),
                                'child_cats' => get_child_categories($cat),
                                );
        } // foreach sonu

        return $ret_arr;

    } // function sonu ##############


?>

and the output is;

To get all the active as well as inactive sub categories

$parent_category_id = 10;

$child_categories = Mage::getResourceModel('catalog/category_collection')
                ->addAttributeToSelect('*')
               ->addAttributeToFilter('is_active', array('in' => array(0,1)))
              ->addAttributeToFilter('parent_id', $parent_category_id);

foreach ($child_categories as $cat)
{
    $sub_category_id = $cat->getId();
    $sub_category_name = $cat->getName();
}
