Hello again all,
I have recently updated some of my server side PHP files to use $_POST insted of $_GET and everything seemed to be working fine however I must have done something (although Im not sure what since I hav’nt worked on these files in a while) because now I keep getting the following when ever I try to perform any operations:
Error type: LoadXML Description: Wrong XML
When I load the connector page directly I get:
[b]
Contents of $_POST:
Array()
Contents of $_GET:
Array()
// nothing is being passed in either get or post??

You’ll notice that both the $_GET and $_POST arrays seem to be empty which is causing everything else to collaps in a heap of Undefined index errors
my data processor is set up as follows:
areaDataProcessor = new dataProcessor ("resources/lib/cons/mySettings/areaPreferences_gridUpdateV2.php");
// create an action to show an error message to the user in the event of a problem
areaDataProcessor.defineAction("error",function (response){
var message = response.getAttribute("message")
alert ("The following error occoured while attempting an area grid operation" + " "+message);
return false
});
areaDataProcessor.enableDataNames(true);
areaDataProcessor.init(areaGrid);
my server side dataprocessor script looks like so:
session_start();
// check that the user is autherised
if (!(($_SESSION['Authorised'] == true) && ($_SESSION['User_Level']) >= 1 )) {
header("Location:index.php");
}
// check that the user has been properly autherised and redirect to the index if not
define('CONFIG_PATH', $_SERVER['DOCUMENT_ROOT'] . '/resources');
require_once (CONFIG_PATH . '\config.php');
require_once(LIBRARY_PATH . '\queries\class.db.proqueries.php');
// include all files required for database connection and queries
$host = $dbConfig ['dbSettings']['mysql']['host'];
$dbName = $dbConfig ['dbSettings']['mysql']['dbname'];
$userName = $dbConfig ['dbSettings']['mysql']['username'];
$pwd = $dbConfig ['dbSettings']['mysql']['password'];
// create variables for connection settings.from config file
$dbConnection = new Proc_Query($host, $dbName, $userName, $pwd);
if (!(isset($_SESSION ['ID']))){
echo "Error while updating area preferences: No user id passed in SESSION variable";
exit();
}
// a global variable to hold the id of any new record
$tid = "";

?>Can anyone see any problems? I’ve been sat here since 10:00 am on a Saturday trying to work out where Ive messed up.
Can anyone help?
Thanks in advance.
