This is an excerpt from the latest version perlfaq9.pod, which
comes with the standard Perl distribution. These postings aim to
reduce the number of repeated questions as well as allow the community
to review and update the answers. The latest version of the complete
perlfaq is at http://faq.perl.org .


9.6: How do I download a file from the user's machine?  How do I open a file on
another machine?

    In this case, download means to use the file upload feature of HTML
    forms. You allow the web surfer to specify a file to send to your web
    server. To you it looks like a download, and to the user it looks like
    an upload. No matter what you call it, you do it with what's known as
    multipart/form-data encoding. The CGI.pm module (which comes with Perl
    as part of the Standard Library) supports this in the
    start_multipart_form() method, which isn't the same as the startform()

    See the section in the CGI.pm documentation on file uploads for code
    examples and details.


The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
are not necessarily experts in every domain where Perl might show up,
so please include as much information as possible and relevant in any
corrections. The perlfaq-workers also don't have access to every
operating system or platform, so please include relevant details for
corrections to examples that do not work on particular platforms.
Working code is greatly appreciated.
