Thats an outdated tutorial. Here is a quick 3.5 version.
Lets name the page first. We will call it.. hmmm... Lets call it
aboutus. The first thing we need to do is create the PHP file for this page. Here is the basic code you need to make a vBulletin powered page.
PHP Code:
<?php
// ####################### SET PHP ENVIRONMENT ###########################
error_reporting(E_ALL & ~E_NOTICE);
// #################### DEFINE IMPORTANT CONSTANTS #######################
define('THIS_SCRIPT', 'NAME_OF_THE_FILE');
// ################### PRE-CACHE TEMPLATES AND DATA ######################
// get special phrase groups
$phrasegroups = array();
// get special data templates from the datastore
$specialtemplates = array();
// pre-cache templates used by all actions
$globaltemplates = array(
'NAME_OF_THE_FILE_TEMPLATE'
);
// pre-cache templates used by specific actions
$actiontemplates = array();
// ######################### REQUIRE BACK-END ############################
require_once('./global.php');
// #######################################################################
// ######################## START MAIN SCRIPT ############################
// #######################################################################
// #############################################################################
// draw navbar
$navbits = array();
$navbits[''] = "NAME_OF_THE_FILE";
$navbits = construct_navbits($navbits);
eval('$navbar = "' . fetch_template('navbar') . '";');
eval('print_output("' . fetch_template('NAME_OF_THE_FILE_TEMPLATE') . '");');
?>
There are 2 things you need to edit with the above code. The two things are the following text.
1.
NAME_OF_THE_FILE (This is the name of the file with out the .php extention)
2.
NAME_OF_THE_FILE_TEMPLATE (This is the name of the template we're going to use)
Lets name the file aboutus.php and edit where it says
NAME_OF_THE_FILE to
aboutus. Lets name the template
aboutus. Now you code should look like this.
PHP Code:
<?php
// ####################### SET PHP ENVIRONMENT ###########################
error_reporting(E_ALL & ~E_NOTICE);
// #################### DEFINE IMPORTANT CONSTANTS #######################
define('THIS_SCRIPT', 'aboutus');
// ################### PRE-CACHE TEMPLATES AND DATA ######################
// get special phrase groups
$phrasegroups = array();
// get special data templates from the datastore
$specialtemplates = array();
// pre-cache templates used by all actions
$globaltemplates = array(
'aboutus'
);
// pre-cache templates used by specific actions
$actiontemplates = array();
// ######################### REQUIRE BACK-END ############################
require_once('./global.php');
// #######################################################################
// ######################## START MAIN SCRIPT ############################
// #######################################################################
// #############################################################################
// draw navbar
$navbits = array();
$navbits[''] = "About Us";
$navbits = construct_navbits($navbits);
eval('$navbar = "' . fetch_template('navbar') . '";');
eval('print_output("' . fetch_template('aboutus') . '");');
?>
Upload that to your forums directory. When you go to your site you going to see a blank white page. This is because you went ahead of me.

You need to create the template. Since
PHP Code:
eval('print_output("' . fetch_template('aboutus') . '");');
is looking for the
aboutus template, then we should make one. Here is the basic core template code.
HTML Code:
$stylevar[htmldoctype]
<html dir="$stylevar[textdirection]" lang="$stylevar[languagecode]">
<head>
<!-- no cache headers -->
<meta http-equiv="Pragma" content="no-cache" />
<meta http-equiv="Expires" content="-1" />
<meta http-equiv="Cache-Control" content="no-cache" />
<!-- end no cache headers -->
$headinclude
<title><phrase 1="$vboptions[bbtitle]">$vbphrase[x_powered_by_vbulletin]</phrase></title>
</head>
<body>
$header
$navbar
<!-- main -->
Hey look mom, I'm on the web! :)
<!-- /main -->
$footer
</body>
</html>
Now you can go shot over to that page and admire what you just created.

Hope this helps.
Welp. I just found
This Page. Guess next time we both should search. hehe.
