[SOLVED] insert record only when auth-code is right

[bluecuracao]

Hello,

 

I'm trying to create an insert record form that only actually inserts when the auth-code entered by the user is correct (=exists in a mysql table). Code is this:

 

 

 

<?php require_once('Connections/connectDB.php'); ?>
<?php
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;
}
}

mysql_select_db($database_connectDB, $connectDB);
$query_RSauth = "SELECT Code FROM auth";
$RSauth = mysql_query($query_RSauth, $connectDB) or die(mysql_error());
$row_RSauth = mysql_fetch_assoc($RSauth);
$totalRows_RSauth = mysql_num_rows($RSauth);

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



if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "insert")) {
if ($RSauth == $_POST['auth']) {
  $insertSQL = sprintf("INSERT INTO Benutzer (Anrede, Vorname, Nachname, Benutzername, Passwort, Firma, telefon, handy, email) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s)",
                       GetSQLValueString($_POST['Anrede'], "text"),
                       GetSQLValueString($_POST['Vorname'], "text"),
                       GetSQLValueString($_POST['Nachname'], "text"),
                       GetSQLValueString($_POST['Benutzername'], "text"),
                       GetSQLValueString($_POST['Passwort'], "text"),
                       GetSQLValueString($_POST['Firma'], "text"),
                       GetSQLValueString($_POST['telefon'], "text"),
                       GetSQLValueString($_POST['handy'], "text"),
                       GetSQLValueString($_POST['email'], "text"));

  mysql_select_db($database_connectDB, $connectDB);
  $Result1 = mysql_query($insertSQL, $connectDB) or die(mysql_error());
}
}
?>

 

 

I'm assuming the line "if ($RSauth == $_POST['auth'])" returns false, cause when i delete it, the insert works. Any ideas on this? Or another method to achive the same result (insert only when the auth-code is correct)? I really tried a lot of stuff and nothing seems to work, help would be greatly appreciated.

To me your code looks a little bit messy. But in short this should do it

 

<?php
if (isset($_POST['auth_code']))
{
   $authCode = $_POST['auth_code'];
   $sql = "SELECT * FROM auth WHERE auth_code = $authCode";
   $result = mysql_query($sql);
   if (mysql_num_rows($result))
   {
       // Do the insert here.
   }
   else
   {
      // Code not found in db.
   }
}

Also, that line you mentioned:

if ($RSauth == $_POST['auth']) 

there is no mention of $_POST['auth'] anywhere in the code. You were using an "auth" table, but that's not the same thing.

Thank you very very much! It works! I just had to correct a tiny mistake (i think) before i got it to work:

 

$sql = "SELECT * FROM auth WHERE auth_code = $authCode";

 

didn't work, but

 

$sql = "SELECT * FROM auth WHERE auth_code = '$authCode'";

 

did.
