Today's Lesson #1

[ #18675 ]

You cannot do this:

<form action='script.cgi?a=foo&b=bar'>

The "params" won't actually be retrievable as params by param(). Split them out into hidden INPUTs.

  • Is the problem on the server-side? Why not just fix your
    server software, instead of futzing with your HTML?
  • CGI.pm unfortunately seems to think a POST request should have no query string or that (if you uncomment a line in CGI.pm) POST data and the query string should be thrown together.

    I hate this behaviour and for PLP chose to put query string fields in %get, posted fields in %post and have %fields there in case you want to get from either. Note that the interface is a hash. That seemed appropriate for key/value pairs.

    I dislike CGI.pm
  • You want
    <form action='script.cgi?a=foo&amp;b=bar'>
    if that's part of an HTML file. You forgot to HTML-entitize the ampersand.

  • If you're using CGI::Simple [cpan.org] then it's just a matter of:
      $q = new CGI::Simple;
      $q->parse_query_string;  # add $ENV{'QUERY_STRING'} data to our $q object
    CGI is dead, long live CGI::Simple! :)
    • Well, the most significant user difference between CGI.pm and CGI::Simple for me would be the lack of sticky form fields. And I use sticky form fields quite a bit, so CGI::Simple doesn't meet my needs.

      • I don't like to mess with HTML, I'd rather it stay out of my program and into a template. Using HTML::FillInForm/Template::Plugin::FillInForm is a lot nicer.
  • If you poke around CGI.pm, you find this comment:
    # Uncomment this line to have the contents of the query string
    # APPENDED to the POST data.
    Just uncomment the following line and get your params the way you should.
