I would recommend using the DB first. If you can't/won't do that, use sessions. I would NOT recommend carrying all the variables along as INPUT TYPE="HIDDEN" -- While that would "work" it makes it much harder to allow, say, a user who got disconnected to complete the form later, or a user whose session timed out because their boss walked in, or... If you've stored their info in sessions, you will still lose it if their session times out. If it's in the DB, then they can complete the form whenever they have time. 100 questions is a lot of questions... You might even allow them to answer different sections in different orders, if there is a nice way to present them with some kind of grouping that's less arbitrary than 1-20, 21-40, ... 'Course, if this is a timed test/exam or something, some of the above is moot... But a student trying to take an exam that gets disconnected? Better to log their session start/end in the DB and only "count" time against them if it is contiguous, if you can. > I read that writing to a database as i go along could be too much of a > hazzle for the db, specially if I have multiple people filling out the > form > at the same time. You're not gonna slam the database unless you have *LOTS* of people filling out the form at the same time. How many is *LOTS* depends on hardware, and you should test this with YOUR hardware/network, but I suspect you are worrying over a non-issue on this. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
