What if it's on an actual web server?

Subject: [Xerte] Desktop Xerte 2.17 -- having trouble reading data from external script











I’m have a devil of a time getting a Xerte app to read the response from a PHP script when run through a browser. It works fine in Preview mode, and I know the script is getting the login information and returning
 a string because in preview mode I receive and can display the correct response with info from my database. I also have the PHP database script email me the same string. This works beautifully in Preview mode, but when I copy my
rlo and other published files to 
localhost and run it from there, Xerte prints ‘undefined’ for the
rawData property returned from a 
sendAndLoadVars call. The database script still emails me the correct response.
 
Here’s what I’m sending to my PHP authentication script (domain is defined in a login script, and the parent Page icon has an id of
loginCheck):
// real
url
URLString = domain + '/wbt/app/admin/authenticate.php';
 
// pass values to external script
loginVars = new
LoadVars ();
loginVars.action = 'authenticate';
loginVars.login = username;
loginVars.sku =
sku;
 
// send to login script
loginCheck.sendAndLoadVars(URLString,
loginVars);
 
Following the above, I have an Interaction with an Event icon (eventName =
onSendAndLoadVars, icon = loginCheck). Attached to the event is a script icon with:
// initialize
btnPath -- assume not authenticated
btnPath = 1; // 1 is the fail path
message = ''; // initialize message
responseMessage = ''; // initialize response message
 
rawStuff =
loginCheck.rawData;
loginInstructions.setText(loginCheck.rawData);
 
//rawStuff = replace(rawStuff, '<sup>®</sup>', '');
rawInfoArray =
rawStuff.split('&'); // save string pairs into an array
 
for (i = 0;
i < rawInfoArray.length; 
i++) { // break pairs into smaller arrays and parse
 

  tempArray =
rawInfoArray[i].split('='); // split on = sign
   

  switch (tempArray[0]) {
   
case 'reg_id':
     
sid = tempArray[1];
     
btnPath = 0;
     
break;
   
case 'message':
     
responseMessage = tempArray[1];
     
break;
 
}
 
}
 
debug('sid: ' +
sid + '\nresponseMessage: ' +
responseMessage);
debug(loginCheck.rawData);
 
// display appropriate response
if (btnPath == 1) {

  message = '<p>Could not retrieve account from the database.</p><br /><p>' +
responseMessage + '</p>';
}
 
I get all the expected debug info in Preview and login is successful. Debug response is:
sid: 71
responseMessage: User Found in Database<br/>
 
reg_id=71&message=User Found in Database<br/>
 
0
 
Any ideas would be appreciated.
