Introduction

After learning how to customize the post editor and taxonomies with custom data fields, the next area that we will be making additions to is the user creation and edition tool. This type of addition can be used for many different purposes, including tracking when users have last visited a site or storing additional data on the types of services they are interested in. This chapter expands on the private content plugin that we started in Chapter 2, Plugin Framework Basics and Chapter 3, User Settings and Administration Pages in the recipes entitled Creating a new enclosing shortcode and Storing stylesheet data in user settings, by adding a second level of content protection that will restrict some posts or pages so that they are only available to paid users.
