Set the session information correctly.

<? session_start();

if((!$_SESSION['username'])&&(!$_SESSION['password'])){


code

}else{

header("location: index.php");

}

?>

or display a message and a link to goto the main page only an example.

<? session_start();

if((!$_SESSION['username'])&&(!$_SESSION['password'])){


code

}else{

echo" Sorry please login <br><br> <A href='index.php'>login please</a";
exit;
}

?>


Only an example hope this helps.
