multipart form data
Hi all,
I am trying to process a HTTP POST using CGI.pm (appended below). The
encoding is multipart/form-data. One(or more) of these parts is(are) jpg
images. I an curently dumping the name = value pairs using the following
program:
#!/usr/bin/perl -wT
use strict;
use CGI;
my $q = new CGI;
print $q-header( text/plain );
my( $name, $value );
open LOGFILE, /tmp/log || die();
foreach $name ( $q-param ) {
print LOGFILE $name=;
foreach $value ( $q-param( $name ) ) {
print LOGFILE $value\n;
}
}
close LOGFILE;
This produces the following output :
BOTZSERIAL=00:02:D3:00:01:01
ALERTPPIC_0=campic1.jpg
ALERTPICTIME_0=984450623
ALERTPPIC_1=campic2.jpg
So it sees the filename but not the data itself. Problem is that I want to
save the Jpg pictures in some other files and the
BOTZSERIAL=00:02:D3:00:01:01 type info in some other file, but I am not
seeing the binary (jpg) data at all. How do I extract the .jpg files from
this POST?
Thanks,

multipart/form-data Method POST to cgi script not working
Hello all,
If anyone could shed some light on this I would be in there debt. I know
what the BIG problem is...these scripts where written in perl5.004 and we
have moved or are moving to 5.6.0, but I don't know where to start looking
to fix the code so that is works with 5.6.0.
This is a multipart/form-data form, using method POST I'm unable to
retrieve the params passed to the cgi via $cgi-param('PARAM'), HOWEVER,
if the method is GET the $cgi-param('PARAM') works, but GET is not
supposed to work with multipart/form-data and doesn't in actually getting
the file sent by the user via an upload script.
I've even gone over the httpd.conf in hopes that it could be in there.
Everything is install RPM, but I've also tried source with the same results.
I will try to include everything that will be of help, but if I forget
something just e-mail me and I'll get it for you.
Thanks in advance,
Chris

The crucial thing you forgot to include is the actual code that is
bombing. I see you are using CGI.pm, but are you using the actual
multipart/form support in CGI.pm (using start_multipart_form)?

I don't see any immediate problem (though maybe it's glaring and I'm just not getting
enough
coffee). Here's a test script you can try to verify that you're getting data sent:
#!/usr/bin/perl -wT
use strict;
use CGI;
use Data::Dumper;
my $cgi = CGI-new;
print $cgi-header,
$cgi-start_html( 'CGI Test' ),
$cgi-pre( Dumper $cgi ),
$cgi-end_html;
That will dump the CGI object to the screen. You'll see something like the following:
$VAR1 = bless( {
'.header_printed' = '1',
'.charset' = 'ISO-8859-1',
'.parameters' = [
'color',
'name'
],
'.fieldnames' = {},
'name' = [
'Ovid'
],
'color' = [
'red'
]
}, 'CGI' );
The '.parameters' will tell you the name of any parameters that were passed and later
you can see
the values associated with the individual parameters. It will also show you cookies,
if
available. They'll be in a CGI::Cookie object.
Basically, if you get no .parameters, you know that the CGI object did not get any
data.
