Uploading files in AS3

programming flash
1

I know this has been covered, but I’ve been working at this sort of thing for months and haven’t made any significant progress. It’s time I asked you folks.

I want to upload a local text file to a server (via FileReference and some PHP) and then have Flash load it (via URLLoader). I have never gotten this to work. And I think the problem lies somewhere between the FileReference.upload() call and the dispatch of the DataEvent “uploadCompleteData”.

To simplify things, I decided this time around to make an Uploader class that handles the entire uploading process. You can view it here:

There’s a chance that this class is entirely sound, and that the issue is with my PHP (which I can make no sense of anyway). But I’m trying to cover all the bases.

Once I get this to work, I’ll probably refine it to be more multipurpose. Feel free to use the class in any way you want. Heck, put it in your own package or something, it’s not like it’s a programming masterpiece. :stuck_out_tongue:
