6. Processors


We’re sorry but this documentation section is outdated. Please have that in mind when trying to use it. You can help us making documentation up to date via Sylius Github. Thank you!

Order processors are responsible of manipulating the orders to apply different predefined adjustments or other modifications based on order state.

6.1. Registering custom processors

Once you have your own OrderProcessorInterface implementation, if services autowiring and auto-configuration are not enabled, you need to register it as a service.

<?xml version="1.0" encoding="UTF-8"?>

<container xmlns="http://symfony.com/schema/dic/services"

        <service id="app.order_processor.custom" class="App\OrderProcessor\CustomOrderProcessor">
            <tag name="sylius.order_processor" priority="0" />


You can add your own processor to the CompositeOrderProcessor using sylius.order_processor

6.2. Using CompositeOrderProcessor

All processor services containing sylius.order_processor tag can be launched as follows:

In a controller:


// Fetch order from DB
$order = $this->container->get('sylius.repository.order')->find('$id');

// Get the processor from the container or inject the service
$orderProcessor = $this->container->get('sylius.order_processing.order_processor');



The CompositeOrderProcessor is named as ` sylius.order_processing.order_processor` in the container and contains all services tagged as sylius.order_processor
