Overview

In this guide you'll learn how to create a custom service using the Symfony DI Container.

Prerequisites

In order to add your own custom service for your plugin, you first need a plugin as base. Therefore, you can refer to the Plugin Base Guide.

Adding service

Adding a custom service requires to load a services.xml file with your plugin. This is done by placing a file with name services.xml into a directory called src/Resources/config/.

Here's our example services.xml:

<plugin root>/src/Resources/config/services.xml
<?xml version="1.0" ?>
​
<container xmlns="http://symfony.com/schema/dic/services"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsd">
​
    <services>
        <service id="Swag\BasicExample\Service\ExampleService" />
    </services>
</container>

Therefore, this is how your service could then look like:

<plugin root>/src/Service/ExampleService.php
// SwagBasicExample/src/Service/ExampleService.php
​
<?php declare(strict_types=1);
​
namespace Swag\BasicExample\Service;
​
class ExampleService
{
    public function doSomething(): void
    {
        ...
    }
}

Note: By default, all services in Shopware 6 are marked as private. Read more about private and public services here.

Next steps

You've now created your own custom service. In the same manner, you can create other important plugin classes, such as commands, scheduled tasks or a subscriber to listen to events.

Furthermore, we also have a guide explaining how to customize an existing service instead.
