A few months back we added a promotions box to our theme on WP “Must-Use” Tutorials. Until today, the promotion has been handled by a template file that we added to the theme. Every time we change the promotion, we had to edit the theme. Since we moved the site to a new server in March, that has required logging in via SSH and editing the template with a text editor.
Since WordPress 3.0 was released I’ve built 10-20 plugins using custom post types. Once you are familiar with the API for them, they’re very quick and easy to create. So, I’ve built a Promotion Box plugin for Genesis which you can download here.
You can see it in action below.
