Practical Module development for Prestashop 8

By: Louis AUTHIE

Overview of this book

After version 1.7, PrestaShop underwent a host of changes, including migration to a Symfony-based system from an outdated legacy code. This migration brought about significant changes for developers, from routine maintenance to module development. Practical Module Development for PrestaShop 8 is curated to help you explore the system architecture, including migrated and non-migrated controllers, with a concise data structure overview. You’ll understand how hooks enable module customization and optimize the CMS. Through the creation of seven modules, you’ll learn about the structure of modules, hook registration, the creation of front-office controllers, and Symfony back-office controllers. By using Doctrine entities, services, CQRS, grids, and forms, you’ll be guided through the creation of standard, payment and carrier modules. Additionally, you'll customize and override themes to achieve your desired e-commerce store look. By the end of this book, you’ll be well equipped to provide modern solutions with PrestaShop that meet client requirements.

Modules can register and unregister to multiple hooks in order to be triggered as soon as those hooks are executed from anywhere in the code. The Modules classes will contain functions named hookNameOfTheHook($params) defining how to behave. Then, we showed how to execute hooks from any type of file in the code.

Hooks are easy to use and enable everyone to customize the shop without having to edit the core files. This way, you can have the core code of PrestaShop on one side and the modules on the other side. If you need to update your core files, you won’t have to change your modules all the time, and that is very important. Hooks also enable one module...
