Flex and Php

Question

FLEX CODE
<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="absolute" applicationComplete="http.send()">
<mx:Button x="197" y="198" label="Button" click =
"testing()"/>
<mx:Script>
<![CDATA[
public function testing():void
mx.controls.Alert.show("this is the output " +
http.lastResult.happy);
]]>
</mx:Script>
<mx:HTTPService id = "http" method="POST" url =
"PHPDocument1.php" useProxy ="false">
</mx:HTTPService>
<mx:TextInput x="260" y="111" id="n"/>
<mx:TextInput x="182" y="45" id="last"/>
</mx:Application>
PHP CODE
<?php
$happy = "<happy>cheesey</happy>";
echo $happy;
?>
The problem I having is for some reason.. it won't even load
anything! it works with loading XML and TXT files but it doesn' t
work with Php or my Python scripts.. basically its unable to
communicate with server-side scripts. What could be the
problem?

Answer 1

Your testing function is not being called. You need to set
the result event like this:
<mx:HTTPService
id = "http"
method="POST"
result="testing(event)"
url = "
http://localhost/PHPDocument1.php"
useProxy ="false"/>
You can then get the result in two differnt ways:
public function testing(evt:ResultEvent):void
mx.controls.Alert.show("this is the output " +
http.lastResult.happy);
trace(evt.result.happy);
Using evt.result is often more flexible than http.lastResult
for me since you are able to decouple the result from the call. It
also is helpful for debugging if there is a problem.
