Hehe… Time heals all wounds. I found the answer.

I’d configured error handling in Global.asax, and it normally redirects to an error page, but in this case, obviously, the only “one” who would see this error page would be the flash app, and it was satisfied with the execution of this page, so hence, no error, no (visible) redirect, just no file.

Fixed.

Please, I have the same problem with 1MB limit, even though the web.config (ASP.NET) is set to much higher (and besides, the default is 4MB).

I’ve managed to determine that if the file is bigger than 1MB the upload script isn’t even run at all. It is only run if the file is below 1MB.

Anybody have an answer for this?

To solve session issue in PHP I dont call session_start() in script that process upload request, so to you keep your script safe, make another security check, with a hash for instance

The URL in FileReference.upload(url.php) does not recognize $_SESSION variables (always undefined even when the session is set) â�� anyone else experience this or have a solution?

Jason: check out my post above and the article I link to (post 117). In firefox the flash file upload gets a separate session from all the other requests, which is what was causing my troubles.

Not sure if you’re having the same problems, but if you are check out that article because I have a solution in there.

Hope that helps.

My implementation of this is working flawlessly in IE but it’s not working in Firefox… I have done what the prior poster suggested which is “substitute the javascript for HTML using param=flashvars”. I am embedding with embed and param tags, no JS.

In firefox when i try to upload the progress bar goes all the way up as if it’s transferring but the files never appear on the server. When i try to download I get a flash dialog window “An IOError occured.”

Does anyone know what the problem might be?

Hi,

Well, I was able to ix the ftp issue, what I’ve to do, is call the chmod command for the files being uploaded. chmod ($uploadFile, 0777);
That’s it…

but now i face one more issue. I just want to list the files (SORTED – either date or name) in the rich file upload – destination folder (tree view component). Is there any way to achieve this?

Thanks

I ran into the same problem with the sessions not being passed and came up with a solution that I’ve posted.

My solution is in Rails, but should be similar with other web frameworks, you can find it here:

Yep, I agree, now am fiddling with ways to change the file permission in php, i.e after uploading the file to the specifica folder with 777 permission, am trying to change the permissions of the files to 777..
Still no luck.. let me see..

Anyway thanks for the responding
