ActionScript FileReference upload onComplete

I am a complete beginner in Flash & Actionscript.

My pet project is this: To provide a www.imageshack.com like service where people could upload single images and later anyone can view it using the generated url.

So far I have gotten to upload an image using Flash and store it in a directory.

http://pixels.guygar.com/

You can check the uploaded image at:

http://pixels.guygar.com/warehouse/

The issue being, I was under the impression when the PHP file is called to store the image in the folder /warehouse the browser would automatically navigate to:

http://pixels.guygar.com/upload.php

Where I can process the image i.e. generate a unique file name and provide the user with a unique URL to later access the resource.

What is happening is the image gets uploaded by the PHP script but the browser page still stays the same page even when providing a new url in the PHP script.

So the question is how do I go about so that a new URL (image resource linked) is passed back to the flash so that onComplete is called I can navigate to image that was just loaded? Or other ways of doing such?

I welcome your perspectives on this issue and thank you for your guidance.

i would store all values that you need later on in a session on the server (don't forget to pass the sessionID to the upload-script via GET).

at the end of the PHP script you just return "ok" (or "ko" if sth went wrong) to flash and then (in the callback/listener) call/load a second PHP-script that's doing the rest ... and returns you an URL to a thumbnail or whatever you want to do.

hope this points you in the right direction ...

Shows how data can be returned to flash after an upload.
