I am creating a game using html, php, javascript, mysql. I can do the database all that is working but the problem I ran across is this, while I was doing more tweaking i got half way thru the form and accidently hit the return button on my keyboard and entered the data to the database incomplete. How can I prevent this? 2 i have a classifcation of races with a column of 7 check boxes to choose the class the problem is i can check all of them is there a way to let u only select 1???? I hope that's clear enough I google but nothing i could come up with seem close to what I am experiencing!
Thanks In Advance,
