Question

I have 2 tables – one storing user information (id, username, password) and the second one storing information about events (id, name, description, date, username(represents the user who created the event)). I would like to implement ‘favourite events’ functionality. This would allow the user to store his favourite events and later display them in a list. I am not sure how to implement this in terms of design. I need a simple solution. Something like storing the IDs of favourite events in a field in the user table. I am using mysql and PHP. Can anyone point me to the right direction?

Answer 1

You want to have a table linking the foreign keys from the user and event tables.

Users Table:

id, username, password

Events Table:

id, name, description, date, username

Favorites Table:

id, user_id, event_id

This way you can easily access the list of favorite events.

SELECT events.name, events.description, events.date
FROM events, users, favorites
WHERE favorites.user_id = users.id
AND favorites.event_id = events.id
