MD5 problem

[Voodoo Jai]

Where do I place a MD5 check sum in the following code, I am trying to hide/secure a password posted to a db.

 

<?php
// *** Redirect if username exists
$MM_flag="MM_insert";
if (isset($_POST[$MM_flag])) {
  $MM_dupKeyRedirect="register.php";
  $loginUsername = $_POST['username'];
  $LoginRS__query = "SELECT username FROM users WHERE username='" . $loginUsername . "'";
  mysql_select_db($database_LostMyMenu_conn, $LostMyMenu_conn);
  $LoginRS=mysql_query($LoginRS__query, $LostMyMenu_conn) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);

  //if there is a row in the database, the username was found - can not add the requested username
  if($loginFoundUser){
    $MM_qsChar = "?";
    //append the username to the redirect page
    if (substr_count($MM_dupKeyRedirect,"?") >=1) $MM_qsChar = "&";
    $MM_dupKeyRedirect = $MM_dupKeyRedirect . $MM_qsChar ."requsername=".$loginUsername;
    header ("Location: $MM_dupKeyRedirect");
    exit;
  }
}

function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  $theValue = (!get_magic_quotes_gpc()) ? addslashes($theValue) : $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;
}

$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
  $editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
  $insertSQL = sprintf("INSERT INTO users (username, pwd, Name, Email) VALUES (%s, %s, %s, %s)",
                       GetSQLValueString($_POST['username'], "text"),
                       GetSQLValueString($_POST['pwd'], "text"),
                       GetSQLValueString($_POST['Name'], "text"),
                       GetSQLValueString($_POST['Email'], "text"));

  mysql_select_db($database_LostMyMenu_conn, $LostMyMenu_conn);
  $Result1 = mysql_query($insertSQL, $LostMyMenu_conn) or die(mysql_error());

  $insertGoTo = "Login.php";
  if (isset($_SERVER['QUERY_STRING'])) {
    $insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";
    $insertGoTo .= $_SERVER['QUERY_STRING'];
  }
  header(sprintf("Location: %s", $insertGoTo));
}

mysql_select_db($database_LostMyMenu_conn, $LostMyMenu_conn);
$query_Users = "SELECT * FROM users";
$Users = mysql_query($query_Users, $LostMyMenu_conn) or die(mysql_error());
$row_Users = mysql_fetch_assoc($Users);
$totalRows_Users = mysql_num_rows($Users);
?>

 

I have already done it with the login page but not sure about register page.

 

Thanks all

you should md5 a password in the sql query.

Then when logging in, md5 the password from a submitted form to check the md5 pwd in the db.

 

hope this helps,
