I published my first tutorial on embedding WordPress into OS Commerce.
 At the time, I was relatively new to working    with OSC, so I was 
unaware of the many different template modules available    for the 
software. Through the comments on my post, I learned that the OSC 
install    that I was working with used the Basic Template Structure 
(BTS). However, people inquired about adjusting my tutorial for use with
 the Simple Template    System (STS). Still more persons asked questions
 pertaining to default installs    of OSC MS2.2.
 Keeping all of these comments in mind, this month I put together a 
default    install of OSC MS2.2 with an integrated WordPress blogWhat follows is    a step-by-step tutorial (with the novice in mind) 
showing you how to do this.    For the many people who are looking for 
an effective way to integrate OS Commerce    and WordPress, I hope this 
tutorial proves to be a valuable and effective contribution    to the 
OSC Community.
- First, you will need to install OSC      MS2.2
 on your web server. This tutorial will assume that your OSC install    
  is located in the default location for a typical OSC install: http://yourdomain.com/catalog/.
- Next, install WordPress      in the /catalog/ directory (i.e. http://yourdomain.com/catalog/wordpress/).      Once you’ve installed WordPress, login to your WordPress admin and set Options      > General > Blog address (URI) to “http://yourdomain.com/catalog/blog.php”      (Note: If you would prefer to have your blog file named something other than      blog.php, be sure to set this value accordingly and rename the file that you upload in step 4).
- Now, just after the opening comments of the /catalog/includes/application_top.php      file, add the following PHP code:
// turn off WordPress themes and include the WordPress core:
define('WP_USE_THEMES', false);
require('./wordpress/wp-blog-header.php');
 
- Next, download these two files (blog.php and stylesheet.blog.css) and place them in the root of your OSC install.
