Product Description

From the Back Cover

Take WordPress to the next level with advanced plugin development

As one of the most popular open source content management systems available today, WordPress boasts a framework that allows you to easily customize and extend it through plugins. This comprehensive book shows you how plugins work, reviews the tools and APIs in WordPress, and demonstrates how to extend the functionality of WordPress with plugins. The trio of authors provides a practical, solutions–based approach along with a collection of timely examples and plenty of code, all aimed at clearly explaining how to create a plugin file, work with users, integrate widgets, add menus and submenus, secure your plugins, and more. You will quickly come to understand how to develop custom plugins so that you can take WordPress to the next corporate and enterprise level.

Professional WordPress Plugin Development:

  • Details the range of complexity in plugins, from a very simple social networking plugin to an extremely elaborate e–commerce package

  • Addresses how to integrate into WordPress, save settings, create widgets and shortcodes, and implement uninstall

  • Unveils the proper techniques for storing data, customizing user roles, and implementing security best practices

  • Shares procedures for using custom post types and creating and using custom taxonomies

  • Explores the HTTP API, JavaScript® and Ajax, Cron, the Rewrite API, and more Programmer Forums

Format: Paperback
I have had released one plugin when I bought this book and have several more in various stages of development. That's probably the right stage to buy this book. It would be OK for somebody starting out, but only if they are a quick learner. There are two things you must know though: PHP and WordPress. This book (rightly) assumes that you have a good knowledge of both of those. It's not necessary to have put the two together before, but it is probably helpful if you have. At the other end, it maybe doesn't go into the technical depth that very experienced developers might want - although as WP keeps evolving it might be hard to do so.

That's not a criticism: it is a fantastic book for somebody who has good foundations and wishes to use them to develop WordPress themes.

It has been written by multiple authors and it shows and that is the main downside because the standard and depth of their explanations is not uniform. Some sections can be handled with good explanations but, for instance, the section on the Settings API is quite poorly explained and relies more on code examples. It is a very good book; but I suspect version two (in a couple of years time?) could be excellent if the consistency is improved. That shouldn't deter anybody from buying it. It is a very good book, and quite possible the best there is at present.

This book is excellent and, as an already prolific WordPress plugin developer (dartiss), still has lots to teach. I'd not recommend it to those starting off though.

My only issue... it's causing me too much work as I now feel the need to re-visit all my plugins and improve them based on what I've learnt in the book!

This was the third ( and probably last) WordPress book I've read and I still learned a lot. It covers the API's in WordPress in just enough detail that you can carry on learning as go. Note that a lot of what applies to plugin development can be used for theme development, they all use the same functions basically.
The other, more general WordPress book by the same authors has recently been updated and includes what is basically a summary chapter on this book ( the APIs) and I would read that one first perhaps .

The first book I read before these two was 'Wordpress for Web Developers' which has more detail on WP from a users perspective whilst also providing more technical chapters on Theme and Plugin Dev.

Not great at all. I am a professional software developer with 20 years experience. I have had to learn so many technologies and languages across the duration of my career, most recently a defunct language from 1972 that has no documentation and no forums, and no tools or communities active. I even managed that easier than learning Wordpress and I have struggled with the haphazard nature of the wordpress eco system and community since I got involved in it mainly because there is no consistency in anything. It is clear the whole WP world has been put together by amateurs and people that decided they didn't like their day job and could do better for themselves with a job doing Web dev. They have even renamed and reinvented (poorly) almost every single concept and terminology that the professional SW development world has used for decades. This book is just the same, haphazard, unprofessional, incohesive (three authors with different native languages) the editorial job is appalling, errors everywhere, and even the erratum online which could easily have been maintained has been completely ignored. The working examples are poorly thought out and poorly explained, often there is information missing from explanations which require me to go online and research elsewhere. More often than not the information is available online and is more complete on the web, but not always. Almost every page has an example of a poorly thought out explanation, and I did think of making a full list of all the omissions and oversights, but it would have taken a long time. Alng with the lack of any real erratum and it does need it, there is an online p2p forum for the book, that has about a dozen post and my own question about a rather ridiculously unclear and unhelpful code example has been ignored for over a month.Read more ›
