Hello,
I'm developing a module which implemented XOOPS notification system. This module's database table structure is very like mylinks module. I have question about it now:
For example, I have a main category -- Restaurant, under which there are 3 sub-categories, -- Fast food, Pizza, and Seafood, like this :
Restaurant
-- Fast food
-- Pizza
-- Seafood
I found if user subscribed notification from Restaurant, then only notifications of new links under Restaurant will be sent out, but what I want is if there is any new links under Restaurant or it's sub-categories, like pizza and seafood, system could send out a notification.
Anyone could help me explaining this, thanks in advance!
