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

I'm currently working on a web application using Template Toolkit, but now I'm experiencing difficulties trying to work out the nicest way to allow dynamic includes.

What I'm trying to do is have a template including other templates dynamically based on either the status of a variable, or the result of a function, so that the following could be made to work. Please note I do know that the 'header' and 'body' in the includes are taken as literals, it's this I'm trying to get round here.

As part of program:

  $template->process(
   'toplevel.html', {
    title => 'Hello, World',
    header => 'current_header.html',
    body => 'welcome_page.html'
   }
  };

[download]

As toplevel.html

<html>
 <head>
  <title>[% title %]</title>
 </head>
 <body>
  [% INCLUDE header %] <!-- To include current_header.html, somehow-->
  [% INCLUDE body %] <!-- To include welcome_page.html -->
 </body>
</html>

[download]

The aim of this is to allow me to associate new actions to page contents without a change either to the basic code, or to the top-level page templates.

I could code up a plugin to do this, but fear reinventing wheels. Any hints?
