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After version 1.7, PrestaShop underwent a host of changes, including migration to a Symfony-based system from an outdated legacy code.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.

Quick presentation of a hook

Before diving deep into the details, let’s describe quickly what hooks are. Hooks are like events that can be triggered from anywhere in the code and are mainly defined by a name. They can be placed anywhere in the controllers’ code of PrestaShop and in the Smarty or Twig templating code of the themes.

Modules are a kind of plugin, just like WordPress extensions. They can be attached to as many hooks as you want. The attachment of a module to a hook is called a registration. When you define a hook. Each hook execution can contain parameters provided to registered modules as a payload of information to transmit the necessary information.

Even if many hooks are pre-delivered in PrestaShop Core, you can also create your own hooks and use them from your modules. As hooks are ObjectModel child objects, let’s see how hook features are stored inside the database.
