In the first three parts of this series you learned theory – how the WordPress plugin API works and how to use it. If you’re like me, however, you’ve been longing for a real life application – thinking, “That looks great, but how do I make the jump to using it in real life?”
Today, that’s exactly what you’re going to get. We’re going to delve in deep and tackle a real-life plugin (called WisdomDistilled) designed to allow easy placement and management of clever quotations. You’ll get to use the stuff you’ve learned – adding a widget and a settings page, saving options, and working with API hooks, plus learn some new techniques related to security, plugin structure, and working with the WordPress database. Are you ready?
