URLLoader Flash to grab PHP Info

Question

I am trying to send a variable from Flash to PHP, and then echo it back to flash (ignore function names etc. for now; just trying to troubleshoot the basics first).

Flash file (call it test.as):

  var myLoader:URLLoader = new URLLoader();
  var file_path:String = "get_this.php";
  var myRequest:URLRequest = new URLRequest(file_path);
  myRequest.method = URLRequestMethod.POST;
  var memberInfo:URLVariables = new URLVariables();
  myLoader.dataFormat = URLLoaderDataFormat.VARIABLES;
  memberInfo.member_id = 10;
  myRequest.data = memberInfo;
  myLoader.addEventListener(Event.COMPLETE, onXMLLoad);
  myLoader.load(myRequest);

  function onXMLLoad(event:Event)
  {
    trace(myLoader.data);
  }

PHP file (get_this.php):

<?php
header('Content-Type: text/xml');
echo "<?xml version='1.0' encoding='UTF-8'?>";

$member_id = $_POST['member_id'];   

echo "member_id=$member_id";
?>

However, when I do this, the trace on "myLoader.data" returns a massive string consisting of every single word in the entire PHP file, including comments, which are omitted on this post (C++/Flash style comments (//) ), with some random numbers separated by % signs. This surely is an easy fix, but I am rather new to PHP (and not too experienced with Flash yet), so if someone could help me out I would be very appreciative.

Answer 1

Firstly, test your PHP on the browser and see if its working as expected. Secondly, your complete function should look like this:

function onXMLLoad(event:Event)
{
   var variables:URLVariables = new URLVariables( event.target.data );
   trace(variables.member_id);
}

Hope this answers your question.
