On my controller I have a variable called 'name' => $child['name'], for my drop down menu.

The problem I am having is that in the child dropdown menu it still shows parent name.

I am trying to make it so if parent_id name is equal 0 then will not show in dropdown child links.

Why is it still showing parent name in dropdown child links

            if ($category['top']) {

                $children = $this->model_catalog_category->get_categories($category['category_id']);

Change your codings for if ($categories) into if (isset($categories) && !empty($categories))
Then if ($category['children']) using same feature and try again.


I tried that no luck very strange but most lilkey a simple fix.


I have solved issue I now use $this->get_categories($category['category_id']); for the child links in controller. When loaded by model function was not working so updated with the function on controller and now working.
