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After version 1.7, PrestaShop underwent a host of changes, including migration to a Symfony-based system from an outdated legacy code.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

We also saw that the /config/defines.inc.php file was also included in the /config/config.inc.php file. Two very useful constants to set are the following:

  • _PS_MODE_DEV_: If you set it to true, it will enable the debug mode for the whole shop. Inside Symfony controllers, you can use the awesome profiler.

Important note

All warnings, notices, and errors will be displayed. Do not use the debug mode in production if you want to keep your user experience safe. It is useful for developers but not for your customers! If you want to disable it, you have to set it to false.

  • _PS_DEBUG_PROFILING_: If you set it to true, you will get...
