<META> tags have to go in the <HEAD> section of the HTML document.
this is an optional suggestion but, overall, one thing that would be
better is to determine (before you send any ouput) if the login was
correct or not, and if not, use an HTTP redirect:
if (bad login) {
header("Location: http://mydomain.com/login.php?tryAgain=1";);
} else {
header("Location: http://mydomain.com/mainpage.php";);
}
(the tryAgain=1 is to tell the script that you want to show a
"login failed, please try again" message)
using a redirect instead of a meta refresh is more user friendly because
(1) it's faster since some browsers force a waiting period before the
refresh happens (as a usability feature), and (2) the user can use
back/forward without running into the "this page contains POST data, do
you want to resend it?" alert, which I avoid in my designs like the
plague (always using a redirect instead of showing output as the result
of a POST action).
