check category have child category or not in magento

Question

I have category id .I got the id from this code

<?php echo $current_catid=$this->getCategoryId(); ?> 

now i want to check that this category have child category or not .

if it have child than it will show the child category image and name and url.

Answer 1

If You have current_category id then load category

$category = Mage::getModel('catalog/category')->load(id);

and check count($category->getChildren());

Other methods are for count children

count($category->getChildrenNodes()); 

$category->getChildrenCount();

This way you can check if category has children or not.

getChildren() methods give you children category id and based on id you can get category image and category name.

Answer 2

Please try this one, its working fine at my end

<?php  
$parentCategoryId = 10;
$categories = Mage::getModel('catalog/category')->load($parentCategoryId)->getChildren();
$catArray = explode(',', $categories);
foreach($catArray as $child)
{
$_child = Mage::getModel( 'catalog/category' )->load( $child );
echo $_child->getName() . '<br />';
echo $_child->getUrl() . '<br />';
echo $_child->getDescription() . '<br />';
}
?>
