In this article I will demonstrate the power and simplicity of developing PHP applications using the WASP Framework through the illustration of a simple user module design pattern. The example code will encompass the creation of a user account and subsequent login validation. In the course of this discussion, we will cover the creation of the three tiers of the application- model, view, and controller-and introduce a simple approach to using AJAX to save application form data and present flexible user interfaces.

The provides the code and database structure to make the application work, including the "touch of Ajax" made using the Prototype Javascript library.
