This module contain script that need to be uploaded in opencart installation folder, same place where config.php file is.

If product is assigned to one category this script will add all parent categegories to 'product categories'.

For example if you have category A that is parent to category B.
A->B
And you have Product P that is assigned to category B.
B->P

After run of this script Product P will be assigned and to category A-

A->B->P and A->P will work.

Also if you have other category C that is parent to A than product will be assigned to A and C.

Make backup on database first.

This script will add assigns in Database and Admin. Not just in frontend.

It is good if you have some fee or coupon based on category.

Or you want to display category products in some custom module
