sorry, a typo
INSERT INTO attendee (event_id, user_id) VALUES ($event_id,
session['user_id'])
I get the event_id via the url since the user does this per event.
eg
event1: 'will attend' 'will not attend'
event2: 'will attend' 'will not attend'
The 'will attend' and 'will not attend' links point to the sql query
inserting in attendee
I hope this helps
