**RJweb** · Aug 5, 2009 17:05

i have a membership system I made from a tutorial, can register users no problem, can view list of users in mysql admin, but cannot login in users, now i registered myself using my login name and pw that I use to login to phpmyadmin, that works fine. I have included my script maybe someone can look at where I made the mistake, thx

<?php require_once('Connections/fradmin.php'); ?>
<?php
if (isset($_POST['pwd'])) { $_POST['pwd'] = sha1($_POST['pwd']); }
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}

$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}
?>
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
session_start();
}

$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
$_SESSION['PrevUrl'] = $_GET['accesscheck'];
}

if (isset($_POST['username'])) {
$loginUsername=$_POST['username'];
$password=$_POST['password'];
$MM_fldUserAuthorization = "";
$MM_redirectLoginSuccess = "test.php";
$MM_redirectLoginFailed = "failedlogin.php";
$MM_redirecttoReferrer = false;
mysql_select_db($database_fradmin, $fradmin);

$LoginRS__query=sprintf("SELECT username, pwd FROM users WHERE username=%s AND pwd=%s",
GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));

$LoginRS = mysql_query($LoginRS__query, $fradmin) or die(mysql_error());
$loginFoundUser = mysql_num_rows($LoginRS);
if ($loginFoundUser) {
$loginStrGroup = "";

//declare two session variables and assign them
$_SESSION['MM_Username'] = $loginUsername;
$_SESSION['MM_UserGroup'] = $loginStrGroup;

if (isset($_SESSION['PrevUrl']) && false) {
$MM_redirectLoginSuccess = $_SESSION['PrevUrl'];
}
header("Location: " . $MM_redirectLoginSuccess );
}
else {
header("Location: ". $MM_redirectLoginFailed );
