Get All Subcategories Of Category

[Edge_jr]

Hi,

 

I want to get all sub categories of given category.

 

Following code gives only subcategory having id_parent from ps_category table.

 

$subcatObj = new Category("6");
$subcatObj2 = $subcatObj->getSubCategories($this->context->language->id);


echo"<pre>";
print_r($subcatObj2);
echo"</pre>";

My category has tree like category1=>category2=>category3=>category4

 

Therefore category4 parent is category 1,2 and 3

 

Any idea?

 

-Thanks

You can use getAllChildren instead, it will get all of the children in the tree. However, you will have to sort them and properly build the tree afterwards.
Otherwise you can just use a recursive function with getSubcategories (if there are results, getSubcategories again, etc)

Hi,

 

Could you please give example use of getAllChildren function or any file in prestashop using it.

 

I think modules/blocktopmenu using to show in menu.

 

$children = Category::getChildren((int)$id_category, (int)$id_lang, true, (int)$id_shop);

 

This function gives only direct subcategories of category not sub sub categories of subcategories.

 

-Thanks

$root_category_id = Context::getContext()->shop->getCategory();

$category_tree = Category::getNestedCategories($root_category_id, $language_id);
