Mi problema es el siguiente:
Estoy realizado un combobox dynamico con tres tablas diferentes, y cuando lo ejecuto me sale Undifinied index. Me estoy volviendo loco, porque lo he realizado siguiendo todos los pasos de un tutorial, pero algo debo estar haciendo mal.
Lo he realizado con Dreamweaver.
El error surge en las lineas 75, 87, 91, 103, 107
Aqui os dejo el codigo:
Código PHP:
<?php require_once('Connections/aluxbd.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;

$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";

return $theValue;
}
