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After version 1.7, PrestaShop underwent a host of changes, including migration to a Symfony-based system from an outdated legacy code.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

Creating the payment validation controller

The payment validation controller is set as the action target URL of our module payment option by using this code:

$cashOfflineOption->setAction($this->context->link->getModuleLink($this->name, 'validation', [], true))

We can now implement this validation controller responsible for creating a new order from the cart. As we already have seen how to create a module front controller, we can create the /modules/whcashpayment/controllers/front/validation.php file containing the WHCashPaymentValidationModuleFrontController class.

It can be implemented with the following code:

class WHCashPaymentValidationModuleFrontController extends ModuleFrontController
  public function postProcess()
    if (!($this->module instanceof WHCashPayment)) {
