Joomla 1.5 Development Cookbook

When I originally received my copy of the Joomla! 1.5 Development Cookbook, I was in the middle of a large client project. The book sat over on my shelf for a few days waiting to be read. While working on my code, I came to a point where I wanted to add some custom markup to the portion of the HTML document. Although I usually whip out my Joomla Textmate bundle to pull up the right snippet, this wasn’t something I already had preprogrammed and ready to go.

If I learned something, you’ll learn something

I was about to do a Google search, but suddenly remembered that James’ book was in arm’s reach and might have the answer. After turning to the index and finding the topic, I quickly located the exact code I needed to move on. Despite having written a book on Joomla myself, this one came to my rescue at just the right time!

While it took me a while to read all 130 recipes (including time on airplanes, buses, and sitting in my living room), the practical tips and methods were worth it. James covers a wide breadth of Joomla programming topics, matched only by his Joomla Framework reference. Most passages are 2-3 pages long and include relevant information that’s quickly applicable to any Joomla project you’re working on.

Essential information

Two chapters in this book really make it a must-purchase for any Joomla developer. The Multilingual Recipes chapter gives more in-depth information on internationalization and character encodings than any other Joomla reference I’ve seen. Even if you’re only creating a website in one language, it’s imperative that you understand how character encodings work. Current versions of PHP have some shortcomings with handling UTF-8 strings, but Joomla’s special libraries will help you handle them correctly.

Character encodings aside, Keeping it Extensible and Modular is the most useful chapter in the entire book. This chapter is devoted to helping you work with Joomla’s different extension types and getting around some of the shortcomings in 1.5. For instance, James shows you how to create installable libraries by creating a custom type of plugin.

Also, this chapter has a recipe for using the component installation process to install additional extensions. This method allows you to include your modules and plugins inside of your component package; installing multiple extensions in one click. I plan on using it as soon as I get a chance to work on the Podcast Suite!

While the content in this book is very strong, it does have a couple of drawbacks. While most of the recipes have readily usable code that’s straightforward, a few of them don’t make a strong case for why you would use the described method. For instance, there’s a recipe on creating and raising a custom error level. It goes into how you want to avoid conflicting with Joomla and PHP error codes, but it doesn’t explain why you would want to create a custom error level in the first place. Fortunately, most of the recipes have more context.

I’m willing to read more than two pages… seriously.

The biggest disappointment of this book is in the execution of the cookbook format. Having read other “programming cookbooks” in the past, I know that the goal of these kinds of books is to help you find relevant information on specific topics quickly. However, Packt seems to have decided that providing “quick information” means catering to readers with severe cases of attention deficit disorder.

If you try to read entire chapters of this book at a time, you’ll notice that some recipes are almost identical. In Chapter 7, there are individual recipes on setting the HTML document generator, description, and metadata. These add up to less than three pages, but all include the same introduction at the beginning of each. Additionally, all three of these include “See also” references to each other. These would have worked much better as a combined recipe, including a reasonable scenario where you would want to set these things. In its current form, almost half of your reading consists of headers and duplicated information.

I get the feeling that Packt was trying to break all of the topics up into the tiniest pieces possible. This way, they’re able to slap “130 simple but incredibly useful recipes” on the cover and advertise a page count of over 300. This is really taking a short view of things, as James did a wonderful job with the topics he covered. While some marketer is probably pushing for a specific length, I’ve found that the length of a book is not proportional to its usefulness. For instance, I learned far more in 145 pages of Javascript: The Good Parts than I did in nearly 800 pages of Programming Ruby.

Hidden Joomla treasures

Despite the sometimes choppy format, the Joomla! 1.5 Development Cookbook organizes a lot of how-tos missing from Joomla’s online documentation. Anyone coding anything more than the simplest module can benefit from the recipes in this book. James demonstrates expert programming knowledge and delivers it in a very accessible format. The time you’ll save by having this information at hand will offset the cost of purchasing it within the first week. If you’re writing code for Joomla, you need this book.

UPDATE: you can also read a PDF sample of Chapter 2 from Packt’s website.

  • Joe,

    Appreciate you reviewing this book. I found the text to be good, but the method listings seem like so much filling. Over and over again, I’m searching for the method that was not listed; or, for a human readable version of the method descriptions.

    Your book was a much better introduction, and James book is a good too. Both must be read in tandem to get the best learning — not one or the other. Then, I’m sure everyone does what I do, and that’s dissect real extensions.

    Thanks Joe!
