From the Author


This book is for professional Web developers who want to make WordPress work exactly how they and their clients want. WordPress has already proven an exceptional platform for building any type of site from simple static pages to networks of full - featured communities. Learning how to code plugins will help you get the most out of WordPress and have a cost - effective approach to developing per - client features.

This book is also for the code freelancers who want to broaden their skill portfolio, understand the inner - workings of WordPress functionality, and take on WordPress gigs. Since WordPress is the most popular software to code and power websites, it is crucial that you understand how things run under the hood and how you can make the engine work your way. Learning how to code plugins will be a priceless asset to add to your resume and business card.

Finally, this book is for hobbyist PHP programmers who want to tinker with how their WordPress blog works, discover the infi nite potential of lean and fl exible source code, and how they can interact with the fl ow of events. The beauty of open source is that it ' s easy to learn from and easy to give back in turn. This book will help you take your fi rst step into a community that will welcome your creativity and contribution.

A formula for success:

1. Put together an idea and outline for a book that hasn't been covered in-depth before.
2. Gather three of the most talented WordPress developers/writers and have them write the book.
3. Release the book and watch the Elves return back to Middle Earth to rejoice with men.

Professional Plugin Development, written by Ozh Richard, Justin Tadlock, and Brad Williams, is a much-needed and very timely book.

There have been several aspiring developers that have approached me saying they needed a start-from-the-basics WordPress plugin development book. And while Professional Plugin Development does teach the basics of plugin development, it quickly moves on to much more complex topics.

The book covers the topics I care most about, such as:

* WordPress Plugin Foundation and Best Practices
* WordPress Security
* WordPress Actions and Filters (aka, hooks)
* And Ajax

But the book goes beyond basic plugin development. It teaches you about plugin options, CRON for scheduling common tasks, storing data (whether it is via post types, transients, or options), the HTTP API (for retrieving remote data), users (how to set up roles and capabilities), localization (err, internationalization), and how to test plugin performance.

For a novice PHP and WordPress developer, this is a good starting point. But don't think of this book as your way to learn PHP, jQuery, or even basic WordPress (there's WordPress for Dummies for that).

This is a book written by developers for developers. And I must say that I learned a lot from this book, and I've been developing WordPress plugins and themes for almost six years.

The first time I went to a WordCamp presentation, the speaker said off-hand, "before I do anything, I check Justin Tadlock's site to see if he's written a tutorial." Before that day, I had never depended on anything but the Codex for support when I wrote plug-ins ... and you could tell by looking at my code.

Since then, I've become a frequent reader of Justin's blog, I've subscribed to several mailing lists for code, and I've started following quality developers - namely the authors of this book - on Twitter. It's been a slow start, but it's changed the way I look at open source and development in general.

And now comes a book written by three of the most respected developers in the WordPress community. It's well written, honest, and comes from a collective background of collaboration and been-there-done-that experience. I've been working with WordPress for more than 4 years now, and this is by far the best reference I've seen to date ... both for developers just starting with the project and for seasoned professionals who build their business on WordPress.

I've seen code written by all three of these developers, built my own systems on the shoulders of their outstanding work, and watched several others grow as developers following after their example. I can't think of any team more qualified to write about WordPress plug-in development, and I can't think of anyone else who'd do a better job.

This is an outstanding book and was definitely worth the 2-month pre-order wait to have a physical copy on my desk to mark up and turn back to. Though I'm confident that the eBook version will be just as useful for those who can't wait for overnight shipping to deliver! :-)

I wish I had this two years ago.

As I implied in the title, I found enough in Chapter 2 to keep me busy for a day or two just cleaning up my existing plugins. While I don't necessarily agree with every guideline (tabs!? Yeeech!), I'm willing to implement each and every one (even tabs!) to get my code up to par.

Seriously, if my code isn't at least par, how could it ever possibly be awesome?

It feels good to be excited again about programming for WordPress.

By the way, anyone serious about WordPress plugin programming will find Ronal Heureca's "WordPress and Ajax" book an indispensable companion to this one.

There aren't many great WordPress books on the market and the topics covered here are not explained in any comprehensive way in the existing online resources. The authors have managed to distill everything you could possibly need to know about plugin development into a well-organized, well-written reference book that I've been calling on a couple of times a week.

Apart from the basics of plug-in development - which it explains very effectively - there are many advanced subjects that any plug-in developer needs to understand. It delves into WordPress actions and hooks, security, best practices, Ajax, the HTTP API, regionalization and how to test for performance.

The book doesn't pretend to teach you PHP and WordPress - you need to be well versed in both to get the most from the material. But if you want to develop plug-ins for either the community or commercial audience, everything you need to know is in here. As an aside, the authors are very well respected WordPress coders so you really couldn't hope to learn from better teachers.
