Joomla Get subcategories of custom parent category

I have a category ID and wan't to display all the subcategories. Show should I do that in Joomla?

I've tried the following 

$catID = JRequest::getVar('id');
$categories = JCategories::getInstance('Content');
$cat = $categories->get($catID);
$children = JCategoryNode::getChildren($cat);
printObject($children);

But it doesn't work.

Solution

  • getChildren is not a static function, you call it off the category object that you get from get, which should be of type JCategoryNode.

    $catID = JRequest::getVar('id');
$categories = JCategories::getInstance('Content');
$cat = $categories->get($catID);
$children = $cat->getChildren();
print_r($children);
