How to pass variables from PHP to Flash (ActionScript 3) - php

Question

I need to select game's number from MySql database and pass It to Flash game (ActionScript 3).
For now I have AS3 code:
function getVars(e:Event):void{
var req:URLRequest = new URLRequest("top.php");
var loader:URLLoader = new URLLoader(req);
loader.dataFormat = URLLoaderDataFormat.VARIABLES;
loader.addEventListener(Event.COMPLETE, getVarComplete);
}
function getVarComplete(e:Event):void{
var gameNr.text = e.target.data;
}
And here is PHP code (I don't know how selected row pass to variable and send It to flash)
$id = $_SESSION['id'];
$mysqli = new mysqli("localhost","xxx","xxx","xxx");
$query = "SELECT GameNr
FROM Game
WHERE FBId = '". mysql_real_escape_string($id) ."'
ORDER BY PlayTime DESC LIMIT 1";
UPDATE:
If I use following PHP:
<?php
session_start();
$id = $_SESSION['id'];
$mysqli = new mysqli("localhost","xx","xx","xx");
$query = "SELECT GameNr
FROM Game
WHERE FBId = '". mysql_real_escape_string($id) ."'
ORDER BY PlayTime DESC LIMIT 1";
if (!$mysqli->set_charset("utf8")) {
printf("Error loading character set utf8: %s\n", $mysqli->error);
}
if ($result = $mysqli->query($query)) {
while ($row = $result->fetch_assoc()) {
echo $row["GameNr"];
}
$result->free();
}
$mysqli->close();
?>
www.myhost.com/top.php returning correct value NA==
If I use following AS3 code:
function onVarsLoaded(e:Event) {
var msg:String = "Communication with the server was successful.\n\n";
msg += "foo -> "+e.target.vars.foo+"\n";
trace(msg);
}
It returning me: foo -> undefined
If I change this
msg += "foo -> "+e.target.vars.foo+"\n"; to
msg += "foo -> "+e.target.vars+"\n";
It returning me incorrect value: foo -> NA=%3D

Try this:
AS3:
import net.kaegi.loaders.VarLoader;
var vl:VarLoader;
sendBtn.addEventListener(MouseEvent.CLICK,sendBtnHandler);
function sendBtnHandler(e:MouseEvent) {
// Variables sent by POST-Method:
var varObj:Object = {};
varObj.textinput0 = escape(textinput0.text);
varObj.textinput1 = escape(textinput1.text);
vl = new VarLoader("http://yourserver.com/landing.php?foo=foo", varObj);
vl.addEventListener(Event.COMPLETE, onVarsLoaded);
vl.addEventListener(Event.CANCEL, onVarsCancel);
}
function onVarsLoaded(e:Event) {
var msg:String = "Communication with the server was successful.\n\n";
msg += "foo -> "+e.target.vars.foo+"\n";
tf_servermsg.textColor = 0x009900;
tf_servermsg.text = msg;
}
function onVarsCancel(e:Event) {
tf_servermsg.textColor = 0x990000;
tf_servermsg.text = e.target.errormsg;
}
PHP
// handle coming get
$foo = $_GET["foo"];
// handle coming post from flash
$textinput0 = $_POST["textinput0"];
$textinput1 = $_POST["textinput1"];
// send it to flash
$yourdata = "hello world"; // your mysql data here
echo $yourdata;

PHP code in addition to your code
$mysqli->real_query($query);
$res = $mysqli->use_result();
while ($row = $res->fetch_assoc()) {
echo $row['GameNr'];
}
Please check in format the data is required from PHP script. currently the php code will give you result of GameNr as text.
Hope it helps!
