The templating system in Drupal, a popular PHP-based content management system, is powerful and Nick Lewis wants everyone to know it. In his latest post, he starts off a series looking to help developers harness this power in their own sites.

This introduction provides the reader with details on a few different topics - making a custom template for the user login form, pass an "editable node" into said form, alter the values in it, and make the page easily accessible for the template file.

Being a tutorial, he steps you through every bit of the way, complete with code and explainations (and screenshots) to make the lesson easier. You'll need to know some PHP before getting into this - it's more than just a simple HTML template change.
