The Best Books to Learn WordPress Development, In Order
This curriculum takes you from absolute beginner to confident WordPress developer in four progressive stages. You'll start by understanding what WordPress is and how to use it, then move into customizing themes and building sites, before diving into PHP-based theme and plugin development, and finally mastering professional-grade workflows and performance. Each book builds directly on the vocabulary and skills established by the ones before it.
