CGI Help Guide
Web Programming with Perl
Don't mix the OO and function oriented interface of CGI for no good reason.
This is an example I use often to test cgi upload scripts.
#!/usr/bin/perl -w
#!C:/perl/bin/perl -w
use CGI::Carp qw( fatalsToBrowser );
use CGI;
#use CGI 2.7; # the minimum acceptable version is 2.7 in my book
use strict;
my $query = new CGI;
print $query->header,
$query->h1("VERSIOn $CGI::VERSION"),
$query->h1("POST MAX $CGI::POST_MAX "),
$query->h1(" DISABLE_UPLOADS $CGI::DISABLE_UPLOADS "),
$query->start_multipart_form();
print $query->filefield(-name=>'uploaded_file',
-default=>'starting value',
-size=>50,
-maxlength=>80);
print $query->submit(),$query->end_form();
print $query->hr();
if($query->upload('uploaded_file')) {
my $fh = $query->upload('uploaded_file');
print "<PRE>Filename: $fh \n";
print "Size: ".(-s $fh)."\n\n";
print while <$fh>; # idiomatic
print "</pre>";
}
If this does not work or reveal why not (old/broken version of CGI.pm, disabled uploads ...), then you need to check your web server configuration (disabled/limited at server level).

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

or How to display code and escape characters
are good places to start.
