In Detail

Joomla! is the world's hottest open-source content management system, and the winner of the 2006 Open Source CMS Prize.

While Joomla! is packed with features, its greatest quality is that it is extremely extensible, allowing any number of complex applications to be cleanly integrated. Shopping carts, forums, social networking profiles, job boards, and real estate listings are all examples of extensions developers have written for Joomla!. All of these can run off one Joomla! site, while only one database, template, and core need to be maintained. When you build an extension to Joomla!, it will inherit the look and feel of the overall site.

If you're eager to start creating extensions for Joomla!, this book is for you. Walk through the development of complete Joomla! 1.5 components and modules with this tutorial for PHP programmers. Written for Joomla! version 1.5 and tested against the final release, this book will get you started coding your first extensions as quickly as possible, and adds the features that will make your work look professional! This book is the most up-to-date introduction to creating Joomla! extensions available.

The book will show you how to use the Model-View-Controller design pattern, pull in common HTML elements, use JavaScript frameworks, manage users, build configuration panels, internationalize interfaces, and manage database records. General knowledge of PHP is assumed, but previous Joomla! programming experience is not.
