upload images to a server from flash

Hi all, I'm developing a drawing application in flash and I want that when a user has finished his drawing, he can upload the file to a server.
I found a code on the web that does what I need, but when I upload the image to the server, there open another window and I don't want it does that, I want simply upload the file to the server without opening another window.

This is the AS code:

Code:

---

import com.adobe.images.JPGEncoder;

save_btn.addEventListener(MouseEvent.CLICK, guardarImg);

function guardarImg(e:MouseEvent):void
{
    var canvasBmp:BitmapData = new BitmapData(360,300);
    canvasBmp.draw(canvas);
    var myEncoder:JPGEncoder = new JPGEncoder(100);
    var byteArray:ByteArray = myEncoder.encode(canvasBmp);
    //hacemos que se libere la memoria después de almacenar el objeto BitmapData.
    canvasBmp.dispose();

    var header:URLRequestHeader = new URLRequestHeader("Content-type","application/octet-stream");
    var myDate:Date = new Date();
    var timeNow:Number = myDate.getTime();
    timeNow.toString();

    var saveJPG:URLRequest = new URLRequest("savejpg.php?nombre=images/dibujo_" + myDate + ".jpg");
    saveJPG.requestHeaders.push(header);
    saveJPG.method = URLRequestMethod.POST;
    saveJPG.data = byteArray;
   
    navigateToURL(saveJPG, "_blank");
}

---

and this is the PHP file:

PHP Code:

---

<?php
if (isset($GLOBALS["HTTP_RAW_POST_DATA"]))
{
    // get bytearray
    $jpg = $GLOBALS["HTTP_RAW_POST_DATA"];

    // add headers for download dialog-box
    //header('Content-Type: image/jpeg');
    $nombreArchivo = $_GET['nombre'];
    $manejadorArchivo = fopen($nombreArchivo, 'w') or die("No se pudo escribir archivo");
    fwrite($manejadorArchivo,$jpg);
    fclose($manejadorArchivo);
}
?>

---

What can I do to avoid it from opening the window when I upload the picture? I've tried to delete this line:
Code:

Code:

---

navigateToURL(saveJPG, "_blank");

---

but if I delete it, the image didn't load. :confused:

thanks!

Try this tutorial: CLICK HERE

It will help you understand the upload process a little better. :)

Thanks enpstudios, I'll have a look.

Ok the example that enpstudios lives here doesn´t exactly what I want. because I don´t want to load an image from a PC to the server. What I want is to load a drawing that a user do in the flash to a server. Finally I get it using sendToURL. The image loads correctly in the server,but I have one more problem, and is that I want a response if the draw loads correctly or if there was an error, and senToURL method haven´t any response. So I'm trying wiht URLLoader with this code:

Code:

---

private function guardarImg(e:MouseEvent):void
        {
            var canvasBmp:BitmapData = new BitmapData(606,516);
            canvasBmp.draw(canvas);
            var myEncoder:JPGEncoder = new JPGEncoder(100);
            var byteArray:ByteArray = myEncoder.encode(canvasBmp);

            canvasBmp.dispose();
            var header:URLRequestHeader = new URLRequestHeader("Content-type","application/octet-stream");

            var myDate:Date = new Date  ;
            var timeNow:Number = myDate.getTime();
            timeNow.toString();
         
            var request:URLRequest = new URLRequest("savejpg.php?nombre=images/draw_" + myDate + ".jpg");
            request.data = byteArray;
            request.method = URLRequestMethod.POST;
            var loader:URLLoader = new URLLoader();
            loader.dataFormat = URLLoaderDataFormat.VARIABLES;
            try
            {
                loader.load(request);
                showSaveMessage(msg);
            }
            catch (e:Error)
            {
                showFailMessage(fmsg);
            }
        }

---

But now nothing happens, no error is displayed and the drawing doesn't load.
:confused:

Finally I got it.

Thanks all for your help.
