WHO THIS BOOK IS FOR

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.

5.0 out of 5 stars It takes true experience to create a book this useful
Reviewed in the United States on March 8, 2011
Verified Purchase
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! :-)

5.0 out of 5 stars Very detailed and thorough technical book
Reviewed in the United States on March 3, 2021

This book is exactly what I was looking for. A completely technical book that explains what to do, how to do it, and most importantly what each command and function does - and with code examples! Excellently written, and shows the refinement that the author intended. Once a person absorbs this complete book, it's pretty much only your imagination and desired functionality that's missing to create a complete solution. Yes, a lot of programming work now lies ahead for you, but the important thing is that you'll know what you're doing and can accomplish it.

While over 90% of my programming references these days are online, I wanted a complete reference that I knew would be correct. Too often the various question and answer sites make you sift through a bunch of incorrect answers, typos, people saying "I don't know the answer, but what about doing...". All that is not helpful, and a time waster. This book takes you back to the programming references of the 80's and 90's when most everything was still in print. But, the content is contemporary.

I purchased this book because of the author. I had read a short article and like his direct, to the point style at a technical level that met my needs (intermediate to advanced WordPress developer). While I don't think that I will be writing any plugins, I wanted to understand the mechanics of how they work and are added to the public domain.

By the way, this is the second book that I have purchased from this publisher. So far they have done a good job.

First of all, a big thank you to Brad, Ozh and Justin for writing this fabulous WordPress book!

I've been working with WordPress for a good five to six years now and I've been teaching myself development along the way by looking through the WordPress source code, reading blogs and Googling and over the years I've been doing things my own way based on what I've learnt.

This book has been such an eye opener for me because there are stacks of tips and ideas I've learnt while I've read the book. I took stacks of notes as I read and I've even typed out our own internal training for our development staff so that we can all be aware of the information in this book and code in line with the WordPress code standards. Not only will this help us internally it's also going to make it easy for our staff to contribute patches to the WordPress core.

I can't rave enough about how great this book is. It's worth it's weight in gold! I wish a resource like this was around years ago!

1.0 out of 5 stars A very poor book for a novice
Reviewed in the United States on December 3, 2018

This is the ultimate "beat around the bush" book. It goes into excruciating detail on everything there is to know about writing plugins... except actually showing you how to do a "Hello World" get-your-feet-wet example. It's almost as if the authors went out of their way to keep you from writing something simple that will work.

It's probably a great book once you know how to construct WordPress plugins --- but worthless for starting out.

5.0 out of 5 stars A must-read for WordPress developers
Reviewed in the United States on May 8, 2013
Verified Purchase
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.

5.0 out of 5 stars Super livre pour apprendre à développer des plugins Wordpress
Reviewed in France on August 9, 2015

Vraiment satisfait de mon achat :-)

Car même si une nouvelle édition serait la bienvenue (le livre date de 2011) pour profiter des nouveautés de Wordpress et de PHP, la plupart des exemples fonctionnent parfaitement sur un Wordpress 4.2, sans ou avec très peu de modifications (par exemple déclaration des constructeurs différente en PHP 5.3 ou bien quelques fonctions de l'API Wordpress qui ont été remplacées).

Ce livre en tout cas permet de bien comprendre comment fonctionne Wordpress et comment coder Widgets et Plugins en tenant compte d'aspects importants comme la sécurité ou bien le multilingue.
