Weird Behavior with URLLoader + PHP Echo

[ScienceSkillz]

Hi experts. I'm having a bit of trouble using URLLoader with PHP echo.

Inside my PHP script I have a session variable which I echo out. If I simply view this in a browser the value looks similar to :

output of $token in browser
195421653823333|2.AQF1F_Pv6fkFj1GR.3200.1312754300 .0-24233010|JdZ5WMGbo65OyRikrKAMqRmW6Co

output is always empty in the flash trace....?

The weird thing is that if I do :

$token = "195421653823333|2.AQF1F_Pv6fkFj1GR.3200.131275430 0.0-24233010|JdZ5WMGbo65OyRikrKAMqRmW6Co";

explicitly in the php script the output does come back to flash properly? My code is below...


PHP code:

<?php session_start();
$token = $_SESSION["user"]["auth_token"];

echo $token;

?>

AS3: Code
function getToken():void{
var request:URLRequest = new URLRequest (currentHost + "flash/getToken.php");

var loader:URLLoader = new URLLoader (request);
loader.addEventListener(Event.COMPLETE, onComplete);
loader.dataFormat = URLLoaderDataFormat.TEXT;
loader.load(request);
var token:String;

function onComplete(evt:Event):void{
token = evt.target.data;
trace(token);
loader.removeEventListener(Event.COMPLETE, onComplete);
}
}

when you echo you have to use a name value pair something like

echo "varName=test"; 

where varName is the name of the variable that it parses and test is the string data that is its value.

I'm confused... wouldn't that only be true if I was using:

loader.dataFormat = URLLoaderDataFormat.VARIABLES?

and also encoded the response?

[calmchess]

u right i didn't look I just thought you were using Variables......pardon me are you only loading text ? Please tell me what data you are loading.

[calmchess]

I'll get back to you in a minute I have to look in the live docs

[calmchess]

i looked and you really need to use Variables with PHP the text attribute is used to read a text file something like myText.txt

[ScienceSkillz]

Alright... can you please provide an example ? of how I would do that?

This is the flash side

package LoadVars0{
    import flash.display.*;
    import flash.events.*;
    import flash.net.*;
    import flash.text.*;
    
    public class LoadVars0 {
        

        public function LoadVars0() {
         var loader:URLLoader=new URLLoader();
         
         loader.addEventListener( Event.COMPLETE, handleComplete);
         loader.addEventListener(SecurityErrorEvent.SECURITY_ERROR,handleSecurity);
         loader.dataFormat = URLLoaderDataFormat.VARIABLES;
         
         loader.load( new URLRequest("http://mydomain.com/theinfo.php"));
          
        }
        private function handleComplete( event:Event):void{
            var loader:URLLoader = URLLoader( event.target );
             switch(loader.dataFormat) {
                case URLLoaderDataFormat.TEXT :
               
                    break;
                case URLLoaderDataFormat.BINARY :
                    
                    break;
                case URLLoaderDataFormat.VARIABLES :
                  
                    trace(loader.data.username);
                    break;
            }

            var test = loader.data.username;
            var test1 = loader.data.ip;
            //trace("username = " + test1);
        }
        private function handleSecurity():void{
            trace("security error");
        }
        
    }
} 

And this is the simplest PHP

echo "username="BOB"&"ip=192.168.1.1"; 

PS. if the php doesn't work you may need to add & sign just before "username .........If i remember right you don't want it in an AS3 loader but u do need it in an AS2 loader.

Hi, Thank you for your help with this. Unfortunately, none of that solved my problem. After more research I found that session variables cannot be echoed back to flash since flash assigns a different session id...Therefore, my solution was to store the session variable in a mysql database and then use php to retrieve the value. Then it properly came back to flash....

But... now I have another problem... the variable contains the special character "|" as shown above. And so when flash reads this from the echo it shows this has been converted to "&" .. How can I make it so it properly returns "|" ??

[calmchess]

you can use session variables hold on i will get you some code

[calmchess]

I set my session data with html and PHP and then call this PHP script with URLLoader to load user name.......don't break into mysite. LOL j/k

<?php session_start();

if(!isset($_SESSION['guname'])){
$username=$_SESSION['IxuG07EZ'];
echo "user=$username";
}else{
$domain=$_SERVER['REMOTE_ADDR'];
$ran0=rand(1,5);
$stlen=strlen($_SESSION['guname'])/$ran0;
$sub0 =substr($_SESSION['guname'],0,6);
$sub1 =substr($_SESSION['guname'],-$stlen,4);
$username=$sub0.$sub1;
echo "user=$username&ip=$domain";
}

?>
