Remember when I mentioned I’d be writing a book on WordPress plugins a while back? Well, my co-authors, Brad Williams and Ozh Richard, and I have wrapped up this thing and WROX is hard at work getting the book ready for publication.
It’s been a long, tough road, but we’ve all strived to bring you the best WordPress plugin development book you can find anywhere. I have more thoughts on the book-writing process and stories from the journey that I plan to share with you in the future, but I just wanted to let you know that you can pre-order the book from Amazon today.
What’s in the book?
Professional WordPress Plugin Development covers everything from the basic plugin foundation to advanced topics such as the HTTP and Rewrite API. You’ll learn things like how to create widgets, build custom content types, and even market your plugin within the WordPress community.
The book has over 80 plugin examples that you can learn from all packed into 500+ pages of content. The plugin examples will also be downloadable from the publisher’s Web site.
Some of the topics we cover include:
- Plugin Foundation: Starting off on the right foot.
- Hooks: The backbone of the plugin system.
- WP Integration: Widgets, meta boxes, etc.
- Internationalization: Readying your plugin for translation.
- Security: Lock down your plugin from attacks and hacks.
- Settings: How to create and use plugin settings.
- Users: Working with users, roles, and capabilities.
- HTTP API: Doing cool stuff like Google Maps integration.
- Shortcodes: Making users’ lives easier with simple-to-use shortcodes.
- Rewrite API: Bending rewrite rules to your will.
- Debugging: How to debug and optimize your code.
- And much more!
The book will be released on March 22, 2011, so go ahead a reserve your copy today.
The authors
Most of you reading this blog know me well, so I won’t say too much about myself here. If you’re unfamiliar with Brad or Ozh, they’re pretty awesome and know their stuff. You can’t find better guys to work with that have both the ability to write clearly and code poetically.
You get the knowledge of three developers who often focus on specific areas of plugin development, so we all bring our own unique talents to the mix. If you want to take a look at some of our publicly-available plugins, check out the following links.
- Brad Williams
- Ozh Richard
- Justin Tadlock (that’s me)

Thanks for the heads up Justin. Congrats. Order placed.
Great. I hope you enjoy it when it arrives.
man! this thing is dam good. I like it
Awesome! Can’t wait to get the book. With all of the WordPress book choices out there, this is the first one that has really appealed to me. Congrats!
I’m also in the same boat. There’s never been another book that appealed to me, especially for people at my skill level. I’ve learned tons of stuff just from reading the chapters Ozh and Brad wrote.
I’ve pre-ordered and I’m anxious to learn more about plugin development so I can take my brainstorms further and continue to give back to the WP community!
You’ll have to give us a plug on your site when you start releasing perfectly-coded plugins after reading our book.
Thanks, order placed !!! any idea when will be ready to delivery?
It should be delivered around March 22, which is the slated release date. Thanks for pre-ordering the book.
I absolutely cannot wait for this! I had been let down by a recent WP book purchase but I know yours will rock.
Wondering, will the book touch on complex usage of the wpdb class? I know it’s in the codex but I’d like to hear it explained by you for a better understanding.
Definitely. It’s covered in both the Settings and Security chapters.
Awesome, I am sure I will be grabbing a few copies of this book. Maybe even give a few away at the next WordCampLA.
Awesome. Let me know if you do. I’ll be happy to let folks know they have a chance of getting a copy there.
I’m sure it’ll be a great book, I’ve landed here and on Ozh’s site more than once googling how to do this and that. Marking the date on the calendar already…
Cool. Let me know what you think of it when it comes out.
Hi Justin – congratulations to all of you on this new essential book og WP plugins. As usual you have my sincere respect on your dedication to quality!
Thanks. It’s been a fun (and sometimes tough) journey so far. I just hope everyone enjoys it and we get some quality-coded plugins out of it.
I have already published a couple of programs but I am sure there are things I can do better. Copy pre-ordered of course.
Thanks for pre-ordering. There’s definitely a little something for developers of all levels. Heck, I’ve even learned tons of stuff from reading my co-authors’ chapters.
Congrats on finally finishing the book. With you three all-stars in one book, can’t see how it could go wrong. I wonder if each of your personalities shines through in your respected parts in the book?
I’m sure each of our personalities is evident in some form or fashion. I’m probably not the best judge of that though because I’ve read through each chapter 30 or 40 times, so it’s all starting to blur together now.
If the Canadians prefer Chapters/Indigo, I found it available for pre-order there as well. Always a bit more expensive – but I had a gift card so I’m still ahead
Thanks for pointing that out. I’ve never even heard of that online store. We need to see about getting a proper image up there.
For any other Canadians that are interested, you can get Pro WP Plugin Development on chapters.indigo.ca.
This is great, I need to have this book.
Onya Justin! Admiration for setting yourself a goal and sticking to it. You have a talent for all things WP and I look forward to the book. Pre-order placed!
I bet mine will be the only copy shipped to Papua New Guinea!
Robert
Maybe we can sell a few more copies there if we get you out evangelizing the book.
Congratulations, I can’t wait to get a hold of a copy!
Just found out: $28,69 magically add up to €38,99 at amazon.de (Germany). That’s almost doubling the price. Not that it wasn’t worth it, and with shipping costs and all it still might be a good price, so: order placed.
That is quite a bit with the current exchange rate. I hope our writing and plugin examples help you make some money.
Good news; I pre-ordered in november already
And Caspar: with Amazon.com it’s $36.67 (including shipping to the Netherlands)
Gonna get my credit card reactivated just so i can get this
Definitely getting it.
I don’t build plugins a lot (mostly themes) but i’m sure 60% of the book content has valuable info for WordPress development in general. Am i right?
There’s a lot of crossover between themes and plugins. Obviously, the book comes at WordPress development from a plugin development point of view, but nearly everything covered in the book applies to theme development (or any kind of WordPress development).
@Tibor Thanks for the tip! I actually tried Amazon.com first. Including expedided shipping (I just don’t want to wait a month or so after the book has been shipped!) my order was up to $41… which didn’t make a difference then. Maybe back in November you got a different kind of a deal?
Hi Justin, very good news. Going to order asap.
What is the release date for the book? Amazon.fr has it listed as February 28th while the US site has it for March.
It’s slated for March 22, but it’s possible it might be released earlier. I would just count on the March release, but if it’s released sooner, you’ll have a happy surprise.
Any chance to have an ebook version of it?
As far as I know, there’ll be an e-book version of it when the book is released.
And here is the link: http://www.amazon.fr/Professional-WordPress-Plugin-Development-Williams/dp/0470916222/ref=sr_1_1?ie=UTF8&qid=1295940158&sr=8-1
pre-order (tick). happy face (tick).
Awesome! Thanks for pre-ordering.
I’ll be the first person to admit I don’t read many books (unless it really interests me), but I think you’ll find it hard for me to put it down! — I’ll have code coming out of my ears, and plugins appearing all over the place, now just for the waiting!
HAHA
To be honest, I don’t read many development books, so this was definitely a tough yet exciting challenge. Part of the challenge was putting something together I would’ve used as a I was just getting into development. If I had this book on hand when I first started creating plugins, it would’ve made tons of stuff much easier.
Great Justin. Perfect timing. The quality of WP plugins is the only downside of working with the platform in 2011 for me.
I just started learning Wordpress plugin development about a month ago and i found about the book through Ozh’s site. I already pre-ordered it, it covers a lot of stuff; i’m sure it won’t dissapoint me.
Thank you very much, Justin. I’d wish more talented developers would write awesome books like this.
Just got notice my book shipped today yeah! Looking forward to diving into it.
I read the Look inside pages on Amazon – looks good!
I’ve just ordered the book on Amazon. Looking forward to getting it!
Do you have also affiliate programs for selling this book?
Thanks,
Maor
Onya Justin! Admiration for setting yourself a goal and sticking to it. You have a talent for all things WP and I look forward to the book. Pre-order placed!
Thanks for the heads up. Congrats. Order placed.
