5. Calculating shipping cost¶

Calculating shipping cost is as simple as using the sylius.shipping_calculator service and calling calculate method on ShippingSubjectInterface.

Let’s calculate the cost of existing shipment.

public function myAction()
{
    $calculator = $this->get('sylius.shipping_calculator');
    $shipment = $this->get('sylius.repository.shipment')->find(5);

    echo $calculator->calculate($shipment); // Returns price in cents. (integer)
}

What has happened?

• The delegating calculator gets the ShippingMethod from the ShippingSubjectInterface (Shipment).
• Appropriate Calculator instance is loaded, based on the ShippingMethod.calculator parameter.
• The calculate(ShippingSubjectInterface, array $configuration) is called, where configuration is taken from ShippingMethod.configuration attribute.
