Product Price Calculation

CoreShop employs multiple Price Calculators to determine the correct price for a product. By default, the following calculators are used:

For custom calculators, implement the interface CoreShop\Component\Product\Calculator\ProductPriceCalculatorInterface and register your service with the tag coreshop.product.price_calculator, including attributes type and priority.

CoreShop Price Calculation Components​

CoreShop's price calculation encompasses three distinct prices:

  • Retail Price: The base price without any discounts.
  • Discount Price: A special price for promotions, which should be lower than the retail price.
  • Discount: Monetary value of discounts from promotions.
  • Price: Calculated as the Retail Price or Discount Price (whichever is applicable) minus any discount rules.

Calculator Service Usage​

To calculate the price for a product, use one of the following services:

  1. coreshop.product.price_calculator: Calculates prices without tax considerations.
  2. coreshop.product.taxed_price_calculator: Calculates prices with or without tax considerations (recommended).

Templating​

For price calculation within a template, use the coreshop_product_price filter:

{{ (product|coreshop_product_price(true)) }}

Custom Price Calculator Example This example demonstrates how to add a new calculator, using the property "price" - 1 as the Product Price, and -1 as the Discount. Note that this example is a demonstration and not a practical implementation.


<?php

namespace App\CoreShop\Product;

use CoreShop\Component\Product\Calculator\ProductPriceCalculatorInterface;
use CoreShop\Component\Product\Model\ProductInterface;

final class CustomPriceCalculator implements ProductPriceCalculatorInterface
{
    // Implementation of methods
}

Registration of the custom service in the container:

App\CoreShop\Product\CustomPriceCalculator:
  tags:
    - { name: coreshop.product.price_calculator, type: custom, priority: 1 }

With this setup, CoreShop will now use your custom service for all Product Price Calculations.
