I have a submit button that processes a sql insert statement. How do I prevent the statment from resubmitting itself when the user refreshes the page with either an F5 or with the IE refresh option?

Don't cross-post.

after mysql_query() which inserts some data to db, call header("location: whatever.php"), like this:

$sql = "INSERT INTO tb_name VALUES ('whatever')";

if(mysql_query($sql,$conn))
{
   header('location: whatever.php');
   exit;
}
