We released a plugin that performs the session start and end functions described in my previous post on Using the PHP Session in WordPress.
The plugin is described at Simple Session Support.
We have rebranded “Devon Road Websites” to “Silver Maple Web”. Silver Maple Web will be offering all the web design and development services currently offered by Devon Road Websites, Devondev Inc. and Prime Admin Solutions.
We provide custom web design and development using modern web standards. We use WordPress as a Content Management System to allow our clients to update their site without programmer skills. Please view our Case Studies for some examples.

Use of the plugin is described on the Simple Promo Code page.

I will be posting an annotated version of the code as a tutorial in the near future. In particular this plugin provides a small example of an HTML form that performs validation, updates a database and redirects the user to another page when complete.
