Question

I am trying to make a simple Flash ActionScript3 program that saves some text to a text file (on my server) via a PHP script. I want the Flash program to be able to detect if the PHP script fails to write. Right now I’m just trying to get Flash to trace a status received from PHP. My below code is based on a few examples I’ve found online.

Here is my Flash code:

import flash.net.*;
import flash.events.*;

var varLoader:URLLoader = new URLLoader;
var varURL:URLRequest = new URLRequest("http://xxxxxxxx/outputTest.php");
var submittedData:URLVariables=new URLVariables();
varURL.data = submittedData;
varURL.method = URLRequestMethod.POST;

submittedData.inputData = "ThisIsTheDataToBeSaved";
submittedData.FileName = "ThisIsTheFileName";
varLoader.addEventListener(Event.COMPLETE, fxnDoneSaving);
varLoader.load(varURL);

function fxnDoneSaving(evt:Event):void{
    trace("Done saving.");
    trace("Write status: "+String(evt.target.data.WasWritingSuccessful));
}

Here is my PHP code:

<?php

$receivedFromFlashData = $_POST['inputData']; 
$receivedFromFlashFileName = $_POST['FileName']; 

$filename = $receivedFromFlashFileName . ".txt";
$myTextFileHandler = fopen($filename,"w"); 

if($myTextFileHandler)
    {$writeInTxtFile = @fwrite($myTextFileHandler,"$receivedFromFlashData");}      

fclose($myTextFileHandler); 

if ($writeInTxtFile)
    {echo "WasWritingSuccessful=success";}
else
    {echo "WasWritingSuccessful=failure";}

?>

When Flash gets to the final trace statement, I get the following error:
“ReferenceError: Error #1069: Property WasWritingSuccessful not found on String and there is no default value.”

Please help me understand what I’m doing wrong? thanks!

You need to specify the dataFormat of varLoader like so: varLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
