Installation

1. Run composer require 3brs/sylius-payment-fee-plugin

2. Add plugin class to your config/bundles.php

   return [
      ...
      ThreeBRS\SyliusPaymentFeePlugin\ThreeBRSSyliusPaymentFeePlugin::class => ['all' => true],
   ];

3. Add plugin configuration to your config/packages/_sylius.yaml

   imports:
      - { resource: "@ThreeBRSSyliusPaymentFeePlugin/Resources/config/config.yaml" }

4. Your Entity PaymentMethod has to implement \ThreeBRS\SyliusPaymentFeePlugin\Model\PaymentMethodWithFeeInterface. You can use Trait ThreeBRS\SyliusPaymentFeePlugin\Model\PaymentMethodWithFeeTrait.

   • see test PaymentMethod for inspiration

   For guide how to use your own entity see Sylius docs - Customizing Models

5. JavaScript Integration - Register the Stimulus controller for dynamic calculator configuration forms:

   The plugin includes a Stimulus controller (payment-calculator_controller.js) that handles dynamic prototype forms for payment method calculator configuration. This allows the calculator configuration fields to appear/change dynamically when you select a calculator type in the admin panel.

   Manual Steps Required:

   a. In your application's admin entrypoint file (e.g., assets/admin/entrypoint.js):

   import { startStimulusApp } from '@symfony/stimulus-bridge';
   import PaymentCalculatorController from '../../vendor/3brs/sylius-payment-fee-plugin/src/Resources/assets/admin/controllers/payment-calculator_controller';
   
   // Start Stimulus app
   export const app = startStimulusApp();
   
   // Register the payment calculator controller from the plugin
   app.register('payment-calculator', PaymentCalculatorController);

   b. Rebuild your assets after adding the controller:

   yarn install
   yarn build

   How it works:

   • When you select a calculator type (e.g., "Flat rate") in the payment method form, the controller dynamically loads the appropriate configuration fields
   • On the edit page, it preserves existing saved values
   • On the create page, it initializes empty fields for the selected calculator
   • The controller uses Stimulus data attributes: data-controller="payment-calculator", data-payment-calculator-target="select", and data-payment-calculator-target="container"

6. Create and run doctrine database migrations:

   bin/console doctrine:migrations:diff
   bin/console doctrine:migrations:migrate

Development

Usage

• Alter plugin in /src
• See bin/ dir for useful commands

Testing

After your changes you must ensure that the tests are still passing.

composer install
bin/console doctrine:database:create --if-not-exists --env=test
bin/console doctrine:schema:update --complete --force --env=test
yarn --cwd tests/Application install
yarn --cwd tests/Application build

bin/behat
bin/phpstan.sh
bin/ecs.sh
vendor/bin/phpspec run

Opening Sylius with your plugin

1. Install symfony CLI command: https://symfony.com/download

   • hint: for Docker (with Ubuntu) use Debian/Ubuntu — APT based Linux installation steps as root user and without sudo command
     • you may need to install curl first apt-get update && apt-get install curl --yes

2. Run app

   (cd tests/Application && APP_ENV=test bin/console sylius:fixtures:load)
   (cd tests/Application && APP_ENV=test symfony server:start --dir=public --port=8080)

• change APP_ENV to dev if you need it
