hi i would like to know how i can stop multiple form insertion. What i mean is after you submit a form if you refresh the browser sends the script again. I done this with the header() function to resend the user but i also need to show a message saying the data was inserted successfully. I used a session but i don't know how to unset it correctly so when the user refreshes the message goes away. If anyone knows another way or a way i can remove the session after the message has been shown please let me know, thanks.
