I have a registration form and if a user enters bad information and the php script generates an error, I want the user to be able to hit back and have his inputs still there. Most websites I've ever used do this, but for some reason, my form loses all its data when the back button is pushed. This doesn't seem like something unique to PHP, but I thought maybe you guys could shed some light. Maybe a header which instructs the browser to cache it? Btw, I plan on having the script reprint the form with the old values anyway, but for reference I'd really like to know because I haven't been able to figure it out. Thanks for any help! =) -Me
