The number of e-commerce websites has drastically increased in these past few years. Building your own web store is a complex and expensive task; that's why open source solutions such as PrestaShop have become so successful in tackling this issue. The main interest with open source solutions is that you can easily add or edit features by creating modules.

This practical, hands-on guide provides you with a number of clear, step-by-step exercises to help you understand how PrestaShop works, and also help you add and edit features.

Starting with the basics, this book takes you through complete module development in an effective manner. You will learn about module architecture, what a hook is, and how to use it to add functionalities to PrestaShop. You will also see how to build payment and carrier modules and make your module multistore-ready. Develop PrestaShop modules the right way and make them secure and compliant with different versions of PrestaShop.
