Getting Price for a Product Line Item

A product line item is a combination of a product, product unit, and quantity. All classes representing a product line item implement the \Oro\Bundle\ProductBundle\Model\ProductLineItemInterface interface. For example, each of these classes is a product line item:

\Oro\Bundle\ShoppingListBundle\Entity\LineItem
\Oro\Bundle\CheckoutBundle\Entity\CheckoutLineItem
\Oro\Bundle\OrderBundle\Entity\OrderLineItem and many more.

Developers frequently need to retrieve a product price for product line items. The OroPricingBundle contains a ProductLineItemPriceProvider to simplify getting and working with pricing data for a consumer product line item.

ProductLineItemPriceProvider

The main entry point for getting product line item prices is \Oro\Bundle\PricingBundle\Provider\ProductLineItemPriceProvider (service oro_pricing.provider.product_line_item_price). It provides the following methods:

getProductLineItemsPrices - to get product line item prices for the specified product line items, price scope criteria and currency. Price scope criteria and currency, if not specified, are detected automatically based on the current context.
getProductLineItemsPricesForLineItemsHolder - to get product line item prices for the specified product line items holder (\Oro\Bundle\ProductBundle\Model\ProductLineItemsHolderInterface) and currency. Price scope criteria is detected automatically based on the specified product line items holder. Currency, if not specified, is detected automatically based on the current context.

Note

ProductLineItemPriceProvider implements \Oro\Bundle\PricingBundle\Provider\ProductLineItemPriceProviderInterface interface so it can be easily overridden or customized if needed.

Provider returns a collection of product line item price objects:

\Oro\Bundle\PricingBundle\Model\ProductLineItemPrice\ProductLineItemPrice - represents a price of a regular product line item.
\Oro\Bundle\PricingBundle\ProductKit\ProductLineItemPrice\ProductKitLineItemPrice - represents a price of a product kit line item (i.e., that is a line item of a product kit - additionally implements \Oro\Bundle\ProductBundle\Model\ProductKitItemLineItemsAwareInterface). Contains \Oro\Bundle\PricingBundle\ProductKit\ProductLineItemPrice\ProductKitItemLineItemPrice objects representing prices for its kit item line items.

Examples

You have a shopping list and want to get prices for all of its line items:

namespace Acme\Bundle\DemoBundle\Pricing;

use Oro\Bundle\PricingBundle\Provider\ProductLineItemPriceProviderInterface;
use Oro\Bundle\ShoppingListBundle\Entity\ShoppingList;

class MyCustomService
{
    private ProductLineItemPriceProviderInterface $productLineItemPriceProvider;

    public function __construct(ProductLineItemPriceProviderInterface $productLineItemPriceProvider)
    {
        $this->productLineItemPriceProvider = $productLineItemPriceProvider;
    }

    public function myCustomMethod(ShoppingList $shoppingList)
    {
        // ...

        $productLineItemsPrices = $this->productLineItemPriceProvider
            ->getProductLineItemsPricesForLineItemsHolder($shoppingList);

        foreach ($shoppingList->getLineItems() as $key => $lineItem) {
            $productLineItemPrice = $productLineItemsPrices[$key] ?? null;
            // ...
            $price = $productLineItemPrice->getPrice();
            $subtotal = $productLineItemPrice->getSubtotal();

            // ...
        }

        // ...
    }
}

You have a shopping list and want to get prices for part of its line items:

namespace Acme\Bundle\DemoBundle\Pricing;

use Oro\Bundle\PricingBundle\Model\ProductPriceScopeCriteriaFactoryInterface;
use Oro\Bundle\PricingBundle\Provider\ProductLineItemPriceProviderInterface;
use Oro\Bundle\ShoppingListBundle\Entity\ShoppingList;

class MyCustomService
{
    private ProductLineItemPriceProviderInterface $productLineItemPriceProvider;
    private ProductPriceScopeCriteriaFactoryInterface $productPriceScopeCriteriaFactory;

    public function __construct(
        ProductLineItemPriceProviderInterface $productLineItemPriceProvider,
        ProductPriceScopeCriteriaFactoryInterface $productPriceScopeCriteriaFactory
    ) {
        $this->productLineItemPriceProvider = $productLineItemPriceProvider;
        $this->productPriceScopeCriteriaFactory = $productPriceScopeCriteriaFactory;
    }

    public function myCustomMethod(ShoppingList $shoppingList)
    {
        // ...

        $lineItem1 = $shoppingList->getLineItems()->first();
        $lineItem2 = $shoppingList->getLineItems()->last();

        $priceScopeCriteria = $this->productPriceScopeCriteriaFactory->createByContext($shoppingList);
        $productLineItemsPrices = $this->productLineItemPriceProvider
            ->getProductLineItemsPrices([$lineItem1, $lineItem2], $priceScopeCriteria);

        foreach ($productLineItemsPrices as $productLineItemPrice) {
            $price = $productLineItemPrice->getPrice();
            $subtotal = $productLineItemPrice->getSubtotal();
            // ...
        }
        // ...
    }
}

You have a product kit line item in a shopping list and want to get a price for it and its kit item line items:

namespace Acme\Bundle\DemoBundle\Pricing;

use Oro\Bundle\PricingBundle\ProductKit\ProductLineItemPrice\ProductKitLineItemPrice;
use Oro\Bundle\PricingBundle\Provider\ProductLineItemPriceProviderInterface;
use Oro\Bundle\ShoppingListBundle\Entity\LineItem;

class MyCustomService
{
    private ProductLineItemPriceProviderInterface $productLineItemPriceProvider;

    public function __construct(ProductLineItemPriceProviderInterface $productLineItemPriceProvider)
    {
        $this->productLineItemPriceProvider = $productLineItemPriceProvider;
    }

    public function myCustomMethod(LineItem $kitLineItem)
    {
        // ...

        $productLineItemsPrices = $this->productLineItemPriceProvider->getProductLineItemsPrices([$kitLineItem]);

        foreach ($productLineItemsPrices as $productLineItemPrice) {
            if ($productLineItemPrice instanceof ProductKitLineItemPrice) {
                $price = $productLineItemPrice->getPrice();
                $subtotal = $productLineItemPrice->getSubtotal();
                // ...
                foreach ($productLineItemPrice->getKitItemLineItemPrices() as $kitItemLineItemPrice) {
                    $kitItemPrice = $kitItemLineItemPrice->getPrice();
                    $kitItemSubtotal = $kitItemLineItemPrice->getSubtotal();
                    // ...
                }
                // ...
            }
            // ...
        }
        // ...
    }
