This book is aimed at people with existing online stores, built using osCommerce. The book follows a systematic approach whereby users can modify and extend features on their already existing osCommerce site. Each chapter deals with a different aspect , and provides ready-made recipes for modifying code to your requirements. The author starts by explaining basic changes one can make to the design of your store, and then covers features like navigation, images, shipping and payment modules, and even explains how to make changes on the administratora™s side and keeping your own recipes private. This book is for people who are already familiar with osCommerce. It presumes a working knowledge of PHP and HTML, as well as basic understanding of phpMyAdmin for database inserts.
