Registration Page

Hello everybody!
I have been knocking my head to the ground for almost a week with this part. I'm totally new to this scripting PHP phase. I'm using Dreamweaver for my dynamic pages and this registration page is killing me. It does the work for which is intended unless i add the user authentication behavior to it. when a new user is submitted it returns this error message.

Unknown column 'ho234' in 'where clause'

this is my code:

<?php require_once('../Connections/conn_users.php');?>
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
$theValue = get_magic_quotes_gpc()? stripslashes($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";
case "long":
case "int":
$theValue = ($theValue!= "")? intval($theValue) : "NULL";
case "double":
$theValue = ($theValue!= "")? "'" . doubleval($theValue) . "'" : "NULL";
case "date":
$theValue = ($theValue!= "")? "'" . $theValue . "'" : "NULL";
case "defined":
$theValue = ($theValue!= "")? $theDefinedValue : $theNotDefinedValue;
return $theValue;

// *** Redirect if username exists
if (isset($_POST[$MM_flag])) {
$loginUsername = $_POST['user_name'];
$LoginRS__query = sprintf("SELECT `user_name` FROM `users` WHERE `user_name`=`%s`", GetSQLValueString($loginUsername, "-1"));
mysql_select_db($database_conn_users, $conn_users);
$LoginRS=mysql_query($LoginRS__query, $conn_users) 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
$MM_qsChar = "?";
//append the username to the redirect page
if (substr_count($MM_dupKeyRedirect,"?") >=1) $MM_qsChar = "&";
$MM_dupKeyRedirect = $MM_dupKeyRedirect . $MM_qsChar ."requsername=".$loginUsername;
header ("Location: $MM_dupKeyRedirect");

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

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
$insertSQL = sprintf("INSERT INTO `users` (`name`, `lastname`, `user_name`, `password`, `address`, `city`, `state`, `zipcode`, `email`, `phone`) VALUES (%s, %s, %s, %s, %s, %s, %s, %s, %s, %s)",
GetSQLValueString($_POST['name'], "text"),
GetSQLValueString($_POST['lastname'], "text"),
GetSQLValueString($_POST['user_name'], "text"),
GetSQLValueString($_POST['password'], "text"),
GetSQLValueString($_POST['address'], "text"),
GetSQLValueString($_POST['city'], "text"),
GetSQLValueString($_POST['state'], "text"),
GetSQLValueString($_POST['zipcode'], "int"),
GetSQLValueString($_POST['email'], "text"),
GetSQLValueString($_POST['phone'], "text"));

mysql_select_db($database_conn_users, $conn_users);
$Result1 = mysql_query($insertSQL, $conn_users) or die(mysql_error());

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

any idea what a heck did I do wrong?

Welcome to WebmasterWorld!

That error is coming from MySQL, therefore there is a problem with this query:

$LoginRS__query = sprintf("SELECT `user_name` FROM `users` WHERE `user_name`=`%s`", GetSQLValueString($loginUsername, "-1"));

Try something like this:

$LoginRS__query = "SELECT `user_name` FROM `users` WHERE `user_name` = '".GetSQLValueString($loginUsername, "-1")."'";

At a quick glance, it looks like you used backtics `, where you probably wanted single quotes ', in your WHERE clause:

`%s` should be '%s' in your query. Like this:
$LoginRS__query = sprintf("SELECT `user_name` FROM `users` WHERE `user_name`='%s'", GetSQLValueString($loginUsername, "-1"));

The ticks are used when the value refers to a column in MySql. Since there is no column labeled ho234, you get an error. Likely what you wanted was to see if the user ho234 existed in the column user_name, ie. user_name = 'ho234'.
