If you're a PHP programmer eager to create extensions for Joomla!, this book is for you. Written for Joomla! 1.5, it gets you coding your first extensions as quickly as possible, and adds features that will make your work look professional! The world's hottest open-source content management system, Joomla! won the 2006 Open Source CMS Prize. Already feature packed, it is also extremely extensible, allowing multiple complex applications to be cleanly integrated, inheriting the look and feel of one Joomla! site, with only one database, template, and core to maintain. This practical tutorial is based around the development of example extensions to create, find, promote, and cross-link restaurant reviews. Each chapter is a step-by-step walkthrough, covering modules, components, and plugins as well as configuration and packaging for distribution. Readers need basic PHP skills and familiarity with the general operation of Joomla! but do not need experience of developing Joomla! extensions.
