jonsmith1982 has asked for the wisdom of the Perl Monks concerning the following question:

im trying to make a mod_perl module, but find that my script is very limited in its lay out, and cant figure out how to use the sub routines correctly. But my main problem at the moment is:-

use Apache2::RequestIO (); # for $r->puts(<<"END");

i would like to use cgi.pm forms and stuff after END which is filled with half a html template then use $r->puts(<<"END"); for the other half of the html template.

But the stuff in the middle (cgi.pm) doesnt display even if i use plain html instead of cgi.pm.

i have also tried print <<END; but this doesnt display anything, please could some1 help me understand where im going wrong.

maybe because its in the middle of a table?>


here is the code:-

package Apache2::CPH;
use strict;
use Apache2::RequestRec ();  # for $r->content_type
use Apache2::RequestIO ();   # for $r->puts
use Apache2::Const -compile => ':common';
use CGI;






sub handler {
    

    my $q = new CGI;


    my $p = shift;
    my $time = scalar localtime();
    $p->content_type('text/html');
    my $uri = $p->uri;
    my $title = substr($uri, 1);
    if ($title =~ "home") {
    $title = "Home"
    }
    elsif ($title =~ "residential_mortgages") {
    $title = "Residential Mortgages" 
    }
    elsif ($title =~ "commercial_mortgages") {
    $title = "Commercial Mortgages" 
    }
    elsif ($title =~ "pensions") {
    $title = "Pensions" 
    }
    elsif ($title =~ "investments") {
    $title = "Investments" 
    }
    elsif ($title =~ "life_assurance") {
    $title = "Life Assurance" 
    }
    elsif ($title =~ "general_insurance") {
    $title = "General Insurance" 
    }
    elsif ($title =~ "contact_us") {
    $title = "Contact Us" 
    }
    else {
    $title = "Home"
    };


    my $content;

    if ($title =~ "Home") {
    $content = "Homepage"
    }
    elsif ($title =~ "Residential Mortgages") {
       $content = "Residential Mortgages"
    }
    elsif ($title =~ "Commercial Mortgages") {
       $content = "Commercial Mortgages"
    }
    elsif ($title =~ "Pensions") {
       $content = "Pensions"
    }
    elsif ($title =~ "Investments") {
       $content = "Investments"
    }
    elsif ($title =~ "Life Assurance") {
       $content = "Life Assurance"
    }
    elsif ($title =~ "General Insurance") {
       $content = "General Insurance"
    }
    elsif ($title =~ "Contact Us") {
       $content = "Contact Us"
    };






$p->puts(<<"END");

    if this is on a windows machine, put the following as the first executable line of code, which flushes buffers properly
    $| = 1;

    the hardest line to type correctly is: stty erase ^H

      I downvoted this answer. Why do you think the OP had a buffering problem?

[reply]
      i have tried $| = 1; and print "<font >© 2006 All Rights Reserved.</font>"; still doesnt display.

      it is a windows machine.
