Robert,
Nether PHP or .net can recognize or handle the file size, even you have
poste it.
It's just a problem of your server.
The bar can also done in Witango.
I have customers where send over 8MB to my server - and it work.
If you are sure, that you have the ultimate solution for uploads, so pls
give it to me.

Subject: Re: Witango-Talk: Simple file upload server on OS X 10.4.8
There are several things here...
First, witango doesn't handle file uploads, and it never has, IIS, or
Apache, or whatever webserver handles the uploads. So apache or IIS
receives the upload, and witango, is COMPLETELY unaware of it, until the
full file is received, and passed from the web server to witango. This
means, you cannot create a http upload solution in witango, that limits
file size. IMHO, this should not be overlooked, because any http upload
solution, should always reject the http upload if the file size is too
big. Every http upload from a browser, has content- length in the header,
so the webserver should reject based on this value. This is not possible
with witango, but it is possible with ASP.NET, and PHP.
With .NET, we used Websupergoo, to provide a progress bar, of the upload
to the user, even for multiple files, and to restrict by file size. Since
.NET is tightly integrated with IIS, it is possible to reject immediately
based on file size, without accepting the whole upload first. However,
one draw back to .NET, is that when the file was rejected, the user
received a page cannot be displayed error, and you had no control over
this, so you had to tell the user ahead of time, they would receive an
error if they uploaded more than the specified size. Another of the
hurdles, was bridging .NET and witango, we did this by accepting the
upload in .net, and forwarding xml to a witango form, and after dealing
with many text encoding issues, we got it done. You can view this
solution in production at one of our currently running contests:
http://www.halloweenphotocontest.com/
http://www.bestofweddingscontest.com/
Now, we have been porting all of our witango code over to PHP, and this
piece, was the toughest, but ended up being bettter than the above
solution. First, we wanted to eliminate paying the several hundred $
license per server for web super goo, and we wanted all of the above
functionality. We found some PHP file upload progress tools, most
requiring a recompile of php, which we did not want to do. We found a
solution, using a couple of small perl cgis, that work with php, that we
were able to modify to work perfectly. So with a combination of PHP 5,
perl, and AJAX, we built a great http upload solution with an ajax
progress bar on the page, even with mult file uploads, and it will reject
files too big, based on content length, and we can also give a good error
page on reject for file size. This solution does not use anything that
you cannot install using YUM from standard fedora 5 repositories, and
also should be able to be ported to OS X PHP5, but haven't done.
You may not have all of these requirements, but take heed on the max file
size issue. My recommendation, is to use websupergoo, cuz its done, you
just buy, and follow their examples. If you are at all familiar with
.NET, it is fairly simple.
The php solution is a completely custom solution we wrote, and is not
going to be made public. If you choose to do this for yourself, there is
a lot of help out there on php upload. But it gets more tricky when you
require progress bar, and file size checking based on content-length.
We can develop this type of solution for you in PHP, but for that you
would have to contact me off list, and I can arrange a demo.

I have a client with a file upload/download server setup 7 or 8 years
ago. It's based on Mac OS 9.2, WebSTAR 4.5 with http uploads using the
WebSTAR File Upload plugin via a very simple webpage. They use Tango 3.5
on the same server for Filemaker database searches
Having dragged them kicking & screaming into the new Milllenium (with OS
X 10.4.8) for everything else, I'd like to retire this server - their
last OS 9 box
They have an Xserve (G4, tray load, 1 GHz, 2 Gb RAM, single processor)
running OSXS 10.4.8 (Apache, MySQL, PHP as installed by default). I'd
like to work with what's there and provide an http upload & download
facility but there's no default file upload plugin
I've looked at many PHP plugins but I've not found anything exactly
suitable and I'm not qualified to say if these solutions are secure or
not. I know I can build /modify one in Witango pretty quickly. The
requirements are:
* an admin webpage to setup usernames & passwords for new accounts
* upload directories created automagically for new accounts
* users to be able to see & upload / download in their directory only
* maximum file size to be 200 Mb (largest files now are ~ 100 Mb)
* useage is light - maybe 2-20 files a day, max, from 2-10 users
The questions are:
* is Witango stable enough for uploading files of this size?
* is there an existing project I can modify? (I have upload.taf from the
Developers site)
* can this be done with Witango Lite?
* if Witango isn't suitable can anyone point me at a PHP alternative?
I've read all the posts in the June 2006 "Question: Upload doesn't work
in Safari" thread and paid heed to Robert Garcia's post. Thank you,
Robert
Many thanks
