Question

function dataGrabbed(event:Event):void
var dataText = input_txt.text
saver.addEventListener(Event.COMPLETE, dataSaved);
saver.save("saver.php","data.xml",dataText);
the above code is a code I am trying to use, but dataText as you can se is just a var, how do I tell ActionScript3 to put dataText into dataXML.options.info.uid ?
saver.php content:
<?php
$content = $_POST['content'];
$file = $_POST['fileName'];
$content = stripslashes($content);
$writeFile = fopen($file, "w");
if(fwrite($writeFile, $content))
  echo $content;
else
  echo "Error writing to file";
fclose($writeFile);
?>

use:
var urlR:URLRequest = new URLRequest("saver.php");
var ldr:URLLoader= new URLLoader();
ldr.dataFormat = URLLoaderDataFormat.VARIABLES;
var urlV:URLVariables = new URLVariables();
urlV.content = input_txt.text;
urlV.fileName = "data.xml";
urlR.data = urlV;
urlR.method = URLRequestMethod.POST;
ldr.addEventListener(Event.COMPLETE, completeF);
ldr.addEventListener(IOErrorEvent.IO_ERROR, IOErrorF);
ldr.load(urlR);
function completeF(e:Event):void {
function IOErrorF(e:IOErrorEvent):void {
