Professional WordPress Plugin Development, 2nd Edition

This paperback is the most directly targeted pick for readers searching specifically for a WordPress plugin development book. Its title identifies plugin development as the central subject, rather than one topic among several. The listed authors are Brad Williams, Justin Tadlock, and John James Jacoby.
Best for: Developers who want a book devoted to WordPress plugins. Choose this if you prefer a dedicated title over a general WordPress guide. The second-edition label also makes the edition easy to distinguish when comparing listings.
Limitation: The supplied listing information does not describe the chapters or technical prerequisites. Check the book’s listing details before buying if you need coverage of a particular development topic or WordPress version.
WordPress Plugin Development: Beginner’s Guide

Vladimir Prelovac’s paperback is explicitly labeled a Beginner’s Guide. That makes it a clear candidate for readers who are new to plugin development and want a book framed for an introductory audience. Its subject is narrower than a general guide to building WordPress websites.
Best for: Beginners comparing dedicated plugin-development books. Choose this if the beginner-oriented positioning matches your experience level and you want the plugin topic to remain the main focus.
Limitation: The provided product information does not state which WordPress or PHP versions the book covers. Readers working with a specific current setup should verify the edition’s technical scope before relying on it as a version-specific reference.
WordPress Plugin Mastery For WordPress 6

Katharine Kincaid’s Kindle edition is titled WordPress Plugin Mastery: Building High-Performance Plugins For WordPress 6. The title signals a focus on plugin building and WordPress 6, giving readers a version-specific point of comparison. It is one of the more narrowly titled options in this selection.
Best for: Readers seeking an ebook whose title explicitly names WordPress 6 and high-performance plugin development. Choose it if that stated focus aligns with your project or reading preference.
Limitation: This listing is for a Kindle edition, not a paperback. Its WordPress 6 focus may not be the right match if you need a book explicitly focused on a different version.
WordPress Mastering Modern Websites

Vignesh R’s Kindle book has a broad scope: its title lists WordPress, theme development, plugin development, ACF, SEO, security, and deployment. Plugin development is included as one part of a wider practical guide, so this book may suit readers who want related WordPress subjects in the same resource.
Best for: Readers who want plugin development alongside topics such as themes, SEO, security, and deployment. Choose this over a dedicated plugin book if breadth is more important than a single-topic focus.
Limitation: Because the title covers many subjects, it may be less suitable for readers looking only for an in-depth plugin-development reference. It is listed as a Kindle edition.
Building Web Apps With WordPress

Brian Messenlehner and Jason Coleman’s paperback is titled Building Web Apps with WordPress: WordPress as an Application Framework. Its framing is broader than conventional plugin instruction: it presents WordPress as a platform for web applications. That perspective can help developers comparing books about extending WordPress beyond standard website use.
Best for: Developers interested in application development with WordPress. Choose it if your goal is to think about WordPress as an application framework rather than focus exclusively on standalone plugins.
Limitation: The title does not position the book as a beginner’s plugin-development guide. Readers seeking step-by-step introductory plugin instruction may prefer a book explicitly labeled for beginners.
Buying Guide: How To Choose A WordPress Plugin Book
Do you want a focused or broad book?
For a single-subject resource, start with a title specifically about plugin development, such as Professional WordPress Plugin Development or the Beginner’s Guide. For several WordPress topics in one book, consider WordPress Mastering Modern Websites. Its title includes plugin development alongside themes, SEO, security, and deployment.
Are you new to plugin development?
Look for explicit audience cues. “Beginner’s Guide” signals an introductory positioning, while the other titles do not make the same promise in their names. Before choosing, check the listing for details about prerequisites and chapter content; those details were not provided for these products.
Does the WordPress version matter?
WordPress Plugin Mastery names WordPress 6 in its title. If you need material for a particular version, compare the book’s stated coverage with the version used in your work. Do not assume that a title without a version number covers your preferred release.
Which format should you choose?
The supplied listings identify three paperbacks and two Kindle editions. Choose based on whether you prefer a physical book or an ebook, and confirm the format shown on the product listing before ordering.
