You said it yourself:

instead of

<h3>Invalid Username or Password! Try Again</h3>

Just remember that you can't send anything to the browser (like "<html><head><title> ..... </head><body> ... dadadadad ... ") - if you're redirecting the browser to another page, there's no point sending it anything on this page (and PHP will refuse to cooperate if you try)!

before the header. So if your page is outputting anything now (it should be) before that <h3> line, you'll have to move it down to after your username/password checking code.

u mean i will have to remove the <h3> ......... </h3>.. and replace it with this line of code ( header('Location: asdf.php'); )... and it will work?

but still face the CGI error... but this file already exists.. what should i do now?

thx..

Yes - like I said, there's no point producing any output on this page if you're going to redirect the browser to another page.

The basic skeleton of this page would be

<?php  // FIRST line in the file.
Get and check user data.
If user data is invalid in some way
{  header('Location:error.php');
    exit;    // Added safety measure.
}
...and if you want to redirect successful logins somewhere else as well:
header('Location:main.php');
exit;
?>

...and note the total lack of HTML.

It's probably not necessary to redirect everyone. It would be simpler (and faster all round) to keep this as your succesful login page. Then you'd have:

<?php  // FIRST line in the file.
Get and check user data.
If user data is invalid in some way
{  header('Location:error.php');
    exit;    // Added safety measure.
}
?>
<html>
<head><title>Welcome</title>
....etc.

You could direct people in different directions based on who they log in as:

<?php  // FIRST line in the file.
Get and check user data.
If user data is invalid in some way
{  header('Location:error.php');
    exit;    // Added safety measure.
}
If user is a preferred member:
{   header('Location:specialmain.php');
    exit;
}
If user has been sent to Coventry:
{    header('Location:lockedout.php');
    exit;
}
...etc... Leaving only the generic logged-in welcome screen to display:
?>
<html>
<head><title>Welcome</title>
....etc.

But what's this CGI error you've started mentioning?
