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.

Chapter 7: Accepting User Content Submissions

Giving users the ability to contribute content to a website is always a good way to engage the community and keep content fresh on a website.

This is even more obvious when you consider that adding a simple contact form to a site requires the installation of a plugin.

Going back to the book review system that was put in place in Chapter 4, The Power of Custom Post Types, this chapter will show you how to create a user-facing form to allow visitors to submit their own book reviews to a website. We'll also see how to save this information in the site database, send out email notifications, and implement spam protection through the following recipes:

  • Creating a client-side content submission form
  • Saving user-submitted content in custom post types
  • Sending email notifications upon new submissions...
