NAME

Apache::PageKit - MVCC web framework using mod_perl, XML and HTML::Template

SYNOPSIS

In httpd.conf

SetHandler perl-script
PerlSetVar PKIT_ROOT /path/to/pagekit/files

PerlHandler +Apache::PageKit
<Perl>
      Apache::PageKit->startup("/path/to/pagekit/files");
</Perl>

In MyPageKit/Common.pm

  package MyPageKit::Common;

  use base 'Apache::PageKit::Model';

  sub pkit_dbi_connect {
    return DBI->connect("DBI:mysql:db","user","passwd");
  }

  sub pkit_session_setup {
    my $model = shift;
    my $dbh = $model->dbh;
    return {
	session_lock_class => 'MySQL',
	session_store_class => 'MySQL',
	session_args => {
			Handle => $dbh,
			LockHandle => $dbh,
			},
	};
  }

  sub pkit_auth_credential {
    my ($model) = @_;

    # in this example, login and passwd are the names of the credential fields
    my $login = $model->input('login');
    my $passwd = $model->input('passwd');

    # create a session key
    # your code here.........

    return $ses_key;
  }

  sub pkit_auth_session_key {
    my ($model, $ses_key) = @_;

    # check whether $ses_key is valid, if so return user id in $user_id
    # your code here.........

    return $ok ? $user_id : undef;
  }

DESCRIPTION

PageKit is an mod_perl based application framework that uses HTML::Template and XML to separate code, design, and content. Includes session management, authentication, form validation, co-branding, and a content management system.

Its goal is to solve all the common problems of web programming, and to make the creation and maintenance of dynamic web sites fast, easy and enjoyable.

You have to write a module named MyPageKit::Common that inherits from Apache::PageKit::Model and provides methods common across the site. For example, if you wish to support authentication, it must include the two methods pkit_auth_credential and pkit_auth_session_key.

For more information, visit http://www.pagekit.org/

Most of the docs have been moved out of POD to DocBook. The sources can be found in the docsrc directory of the distribution, and the HTML output can be found at http://www.pagekit.org/guide

METHODS

The following method is available to the user as Apache::PageKit API.

This function should be called at server startup from your httpd.conf file:

<Perl>
      Apache::PageKit->startup("/path/to/pagekit/files","staging");
</Perl>

Where the first argument is the root directory of the PageKit application. The second (optional) argument is the server id. It loads /path/to/pagekit/files/Model into the perl search path so that PageKit can make calls into MyPageKit::Common and other Model classes. It also loads the Config and Content XML files and pre-parses the View template files.

FREQUENTLY ASKED QUESTIONS

Please look in here before you send me an email.

1) I get a segmentation fault when I start the PageKit enabled Apache server.

PageKit requires XML::Parser, which is incompatible with the expat library included in Apache. You'll have to configure Apache with --disable-rule=expat.

For more information see http://axkit.org/faq.xml under "I install AxKit and Apache segfaults when it starts".

The mod_perl guide (http://perl.apache.org/guide) has an excellect section on compiling mod_perl and Apache from source.

VERSION

This document describes Apache::PageKit module version 1.02

NOTES

Requires mod_perl, XML::Parser, HTML::Clean, HTML::FillInForm, HTML::FormValidator, and HTML::Template.

I wrote these modules because I needed an application framework that was based on mod_perl and seperated HTML from Perl. HTML::Embperl, Apache::ASP and HTML::Mason are frameworks that work with mod_perl, but embed Perl code in HTML. The development was inspired in part by Webmacro, which is an open-source Java servlet framework that seperates Code from HTML.

The goal is of these modules is to develop a framework that provides most of the functionality that is common across dynamic web sites, including session management, authorization, form validation, component design, error handling, and content management.

If you have used (or are considering using) these modules to build a web site, please drop me a line with the URL of your web site. My e-mail is tj@anidea.com. Thanks!

BUGS

This framework is in alpha stage. The interface may change in later releases.
