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After version 1.7, PrestaShop underwent a host of changes, including migration to a Symfony-based system from an outdated legacy code.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

In this chapter, we learned that all data is stored in MySQL tables. There are three types of tables, depending on the localization and the multistore support of each entity. The entities of the core are still stored in the /classes/ folder, and each entity class extends ObjectModel.

We also learned that the Db class must be used to manipulate the data in the database. The core is a set of classes generating the pages of the FO and the BO. The core is MVC pattern-based. The FO and some pages of the BO are using the legacy core. Some BO pages are using the Symfony-based core. The interface with the database is still managed by the ObjectModel child classes during the migration process.

We know now how data is managed, and the design of the core. From a high-level point of view, we know how pages are generated. In the next chapter, we will discover how PrestaShop is initialized both for the FO and the BO, how global variables are set, and how to manually set parameter variables to manage access to the database.
