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After version 1.7, PrestaShop underwent a host of changes, including migration to a Symfony-based system from an outdated legacy code.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

Summary

In this chapter, we got deeper inside the controller’s instantiation process for FO and BO.

We saw that for FO and BO controllers, many constants were initialized inside /config/config.inc.php and /config/defines.inc.php. Some custom constants can be set inside /config/defines_custom.inc.php, depending on your needs. All the database access and cookies parameters can be updated in /app/config/parameters.php.

For legacy BO and FO core controllers, routing is managed by the Dispatcher class located in /classes/Dispatcher.php, whereas for Symfony-based controllers, the Symfony routing component manages it.

It is now time to jump into the FO controller mechanics and see how an FO controller works, retrieves data, uses ObjectModel-based objects, and displays data with the templating engine, which is the topic of the next chapter.
