Why not generate the code in the page that processes the users request and add
the stuff selected
$ID=$firstchar.$secondchar.$rnd_id;
If you want that the user sees the ID while they choose the two letters, then
you need to use javascript to manipulate the HTML page or else you need to
resend the whole form each time you make a change which is a bad idea as it
generates quite a lot of traffic.
