in reply to fundamental mod-perl start_multipart_form question

Bruce,

You would receive better answers if you post code. An HTML form is one element in an HTML page. You can have many (this page does, for me), and you can have much HTML in and around them. They can have multiple submit buttons. So your answers would be 1: NO, 2: YES, 3: YES. That said, it really depends on how you are generating your HTML. There are things that could make what I say untrue with respect to your interface (CGI.pm, for instance), though I suspect these things should generally remain true. :-)

Update: Guessing this is CGI::Application, but what I said should still hold true. Personally, I prefer keeping the HTML (presentation layer) separated from the code, but perhaps that's a separate discussion.

    Yes, I am using Perl with "use CGI qw( :standard escapeHTML);" and "use DBI;". I usually rewrite a small program with the code targeted to my question. But in this case I'm currently only asking the fundamental "only one form" and "must all prints be inside the form" questions. If my program architecture is way off in left field then it needs rewritten rather than debugged. Posting code might only add fog to my direct and to the point question.

    I'm still a bit confused by the "yes" to multiple forms issue. The "Perl In A Nutshell" book indicates that start_multipart_form generates <html> and <body> tags. Shouldn't I only have one set of <html> and <body> tags in a single html page?

    Thanks,
    Bruce
      Your questions are really about CGI.pm and HTML, not about mod_perl. There is good documentation for CGI.pm that should help you. It doesn't look to me like start_multipart_form() prints html and body tags.
        Thank you,
        I'll read through it.

      perrin offers sound advice.

      To clarify, my answers were HTML answers. You can have many forms in a web page. CGI.pm is my preferred module for reading CGI form parameters, but I do not use it to create HTML. Although it doesn't seem to, if start_multipart_form indeed generates <html> and <body> tags, then the answer would be no, since only one of each are allowed. Your browser may be displaying it, but not all will reliably. Good luck!
