WordPress Plugin Development Cookbook - Third Edition

By: Yannick Lefebvre

Overview of this book

WordPress is one of the most widely used, powerful, and open content management systems (CMSs). Whether you're a site owner trying to find the right extension, a developer who wants to contribute to the community, or a website developer working to fulfill a client's needs, learning how to extend WordPress' capabilities will help you to unleash its full potential. This book will help you become familiar with API functions to create secure plugins with easy-to-use administration interfaces. This third edition contains new recipes and up-to-date code samples, including new chapters on creating custom blocks for the block editor and integrating data from external sources. From one chapter to the next, you’ll learn how to create plugins of varying complexity, ranging from a few lines of code to complex extensions that provide intricate new capabilities. You'll start by using the basic mechanisms provided in WordPress to create plugins, followed by recipes covering how to design administration panels, enhance the post editor with custom fields, store custom data, and even create custom blocks. You'll safely incorporate dynamic elements into web pages using scripting languages, learn how to integrate data from external sources, and build new widgets that users will be able to add to WordPress sidebars and widget areas. By the end of this book, you will be able to create WordPress plugins to perform any task you can imagine.

Creating a README file for your plugin

If you look at any plugins on the official WordPress repository, you will see that their page contains a lot of information. This includes a description of the extension, a list of frequently asked questions, and installation notes. As you may have noticed from the work that we have done so far, this data does not reside in the main plugin's code file. Instead, the official WordPress repository looks for this information in a specially formatted readme.txt file that needs to be included with the plugin.

Getting ready

You should have already followed the Updating page title to include custom post data using plugin filters recipe in Chapter 4, The Power of Custom Post Types, to have a starting point for this recipe. Alternatively, you can get the resulting code (ch4/ch4-book-reviews/ch4-book-reviews-v12.php) for that recipe from the book's GitHub page.
