Hi, 

As a follow up to a question I asked and hackishly solved a few years
ago about uploading a file, I am planning on using
$form->{'query_apache'}, in order to upload files.  Can I rely on this
element to remain in getCurrentForm?  Otherwise I will need to split off an
instance of apache::request prior to calling createenvironment, but
even then, according to the Apache::Request documentation, it isn't so
safe to parse a file with an instance.

Anyway, example code follows (different from the similar code in Admin.pl).  

...
my $form = getCurrentForm();
my $apr = $form->{'query_apache'};
my $upload = $apr->upload;
my $loaded;
if($upload){
    $loaded = { type => $upload->type,
	        name => $upload->name,
		filename => $upload->filename,
		fh => $upload->fh,
		size => $upload->size,
	    };
#debug
#    print Dumper($loaded);
    my $filename = $loaded->{'filename'};
    local *BLOB;
    if (! (-d "temp") ){
	if (! (mkdir("temp",0744) )) {
	    carp ("can't make temp  \n"); 
	}
    }
    if( -e "temp/$filename" ){
	unlink "temp/$filename";
    }
    $upload->link("temp/$filename") or
	die sprintf "link from '%s' failed: $!", $upload->tempname;
   # prove it works by echoing
   if($loaded->{'type'} =~ /text/){
	print "<BR><CODE>";
	open(BLOB, "<temp/$filename");
	while (<BLOB>) {
	    print  "$_ <BR>";
	}
	close BLOB;
	print "</CODE>";
    } elsif ( $loaded->{'type'} =~ /image/){
	print "<BR><img src='http:$constants->{'rootdir'}/temp/$filename'>";
    } 
    # other handlers as needed.
}
