in thread File Upload + recording "metadata"

Should perhaps be: 

< my $fh = $query->upload('upload_file');
> my $fh = $query->param('uploaded_file');
# file input control is named "uploaded_file"
and
< open OUTPUT, "/foo/save" or die "Can't open: $!";
> open OUTPUT, "> /foo/save" or die "Can't open: $!";

One problem I've found is that when uploading files larger than around ~60-70k, I get a problem in trying to instantiate CGI.pm. (Apache flips me the bird and takes me to an error screen). Is this a known problem? Has anyone else struck this?

    You're right about the open on the OUPUT filehandle. I think we're both right on the first thing (param vs. upload), though. :) As the CGI.pm docs say this: 
        To be safe, use the upload() function (new in version
    2.47).  When called with the name of an upload field,
    upload() returns a filehandle, or undef if the parameter
    is not a valid filehandle.

            $fh = $query->upload('uploaded_file');

    Calling param on an uploaded file field gives you a thing that's both a string and a filehandle. Using upload just makes sure you get a filehandle, as it's less of a security risk.

    As to your question re: big uploads: do you get any out of memory errors? 60-70k doesn't seem like *that* big a value. Could it be a POST limitation?

      Yes, my apologies. It turns out I was using an old version of CGI.pm Upgraded and unearthed the upload() function.
      Just trolled the apache error logs and can see an error message being generated from mod_perl: 
      [client xxx.xx.xxx.xxx] Request content-length of 84482 is 
larger than the configured limit of 75000

      Which probably explains my problem with file upload size :)
      Thanks a lot for your help.

      *a bit later* Turns out this: 

      LimitRequestBody 75000

      was in my httpd.conf file! *slaps forehead*

        I think the maximum request size is configurable. Check out the LimitRequestBody directive in the Apache docs.
