try this:

edit php.ini

;;;;;;;;;;;;;;; ;
; File Uploads ;
;;;;;;;;;;;;;;; ;

; Whether to allow HTTP file uploads.
file_uploads = On

; Temporary directory for HTTP uploaded files (will use system default
if not
; specified).
upload_tmp_dir = I:\temp

; Maximum allowed size for uploaded files.
upload_max_file size = 2M

Thank you for this input. As I am on shared hosting I can't change the ini
settings; and then there is still the limitation that HTTP uploads are not
convenient at large file sizes (such as 10 MB plus), so I hope to find a
non-HTTP solution.

Why do you say that? I routinely do HTTP uploads that size. Why do you
really think FTP would work better?

Because you don't get any feedback on the state of the upload. As the upload
can easily take several minutes, you have to wait and don't see if the
upload is still going on or your browser crashed.

AFAIK, you will not be able ot find a non-HTTP solution.

If the lack of feedback during file upload is your main concern, you can
try browsing a couple of classes at www.phpclasses.org , perhaps even
http://www.phpclasses.org/browse/package/1554.html or just do a search for
'progress bar'. I haven't tried any of these, but I think that's what you
are after if indeed your big gripe is the lack of client/server feedback.

If you wanted to go non-HTTP for file uploads, you'd have to run a totally
seperate program outside of the web-browser (or a java applet within it).

Good luck...

Ah, sounds like an Internet Explorer problem. Since creating the site I
do big uploads to, I've been using firefox. A progress bar on the lower
right shows the status of the upload.

Have you tried .htaccess to change the setting? Even if you can't edit
php.ini many shared hosting services will allow .htaccess files
(assuming this is apache, of course).

i don't think is necessarily true, in that the progress bar can reach
maximum before a large file is uploaded....

Thanks... I had a look at the phpclasses.org classes, they both just draw
the progress bar, but don't make any relation to a file upload, which seems
to be impossible with PHP. But now I found a small app that uses a Perl
functionality for this:

http://www.raditha.com/php/progress.php/

Raditha also has a very interesting article at his site on building a
web-based FTP app with PHP, where (s)he points out very clearly why PHP/FTP
uploads need an HTTP upload first. And Raditha's company provides a
drag-and-drop upload applet (better than what I was looking for...) at very
reasonable pricing:

http://www.radinks.com/upload/

Thanks all for the discussion.
