Does this look more like what you want?
// Get the loginUsername and password from the request
$loginUsername = $_REQUEST['loginUsername'];
$password = $_REQUEST['password'];
// Create a query using the loginUsername and password
// We want the username, usergroup and ID
$LoginRS__query=sprintf("SELECT username, usergroup, ID
FROM information
WHERE username=%s AND password=%s",
GetSQLValueString($loginUsername, "text"),
GetSQLValueString($password, "text"));
// Execute the query or die with the mysql error
$LoginRS = mysql_query($LoginRS__query, $WebParashaDB) or
die(mysql_error());
// If there is at least one row, then we have succeeded.
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
//here is where i need to enter my text
// Fetch the data from the row
$loginRow = mysql_fetch_assoc($LoginRS);
// declare three session variables and assign them
$_SESSION['MM_Username'] = $loginRow['username'];
$_SESSION['MM_UserGroup'] = $loginRow['usergroup'];
$_SESSION['MM_ID'] = $loginRow['ID'];
// FALSEd out: If there was a previous URL, then go to it.
if (isset($_SESSION['PrevUrl']) && false) {
$MM_redirectLoginSuccess = $_SESSION['PrevUrl'];
}
// Redirect to the Login Success page
header("Location: " . $MM_redirectLoginSuccess );
}
// Otherwise
else {
// Redirect to the Login Failed page
header("Location: ". $MM_redirectLoginFailed );
}
}
