Shopsys Plugin Interface

Package of interfaces providing compatibility between Shopsys Platform and plugins.

This repository is maintained by shopsys/shopsys monorepo, information about changes is in monorepo CHANGELOG.md.

Features

This package contains interfaces responsible for general functionality usable in almost any plugin. For specific functionality, such as generating product feeds, there are separate repositories.

Example

For example usage see the AcmeProductCrudExtension in the CRUD extension section below.

Storing data

Best way to store your plugin data is to use Doctrine entities. Create a folder (e.g. src/Entity) in your plugin and put your entities there. Then you need to create DoctrineOrmMappingPass and add it as CompilerPass in your YourBundleNameBundle class. This can be done like this:

// vendor/your-bundle-name-bundle/src/YourBundleNameBundle.php

// ...

    /**
     * @inheritdoc
     */
    public function build(ContainerBuilder $container) {
        parent::build($container);

        $container->addCompilerPass(
            DoctrineOrmMappingsPass::createAnnotationMappingDriver(
                [$this->getNamespace() . '\Entity'],
                [$this->getPath() . '/Entity']
            )
        );
    }

// ...

This tells Doctrine where to look for your entities. Now you can create Repository and manage your data as you are used to.

CRUD extension

Sometimes your plugin needs some extra information to be included in an entity, for example, you need to track the weight of products. This can be solved by extending the entity CRUD model with your custom sub-form.

To do so you should implement PluginCrudExtensionInterface and tag the service in a DI container with shopsys.crud_extension tag. The tag should have a type attribute defining which CRUD model should be extended (eg. "product").

Each form extension has its label, form type and methods for managing the form data.

Example

services:
    acme.acme_product_crud_extension:
        class: AcmePlugin\AcmeProductCrudExtension
        tags:
            - { name: shopsys.crud_extension, type: product }

    acme.acme_data_form_type:
        class: AcmePlugin\AcmeProductFormType
        tags:
            - { name: form.type }

// ...
class AcmeProductCrudExtension implements PluginCrudExtensionInterface
{
    private $acmeProductFacade;

    public function __construct(AcmeProductFacade $acmeProductFacade) {
        $this->acmeProductFacade = $acmeProductFacade;
    }

    public function getFormTypeClass()
    {
        return AcmeProductFormType::class;
    }

    public function getFormLabel()
    {
        return 'ACME data';
    }

    public function getData($productId)
    {
        $acmeProduct = $this->acmeProductFacade->findByProductId($productId);

        $pluginData = [
            'attribute' => $acmeProduct->getAttribute(),
        ];

        return $pluginData;
    }

    public function saveData($productId, $data)
    {
        $acmeProductData = new AcmeProductData();
        $acmeProductData->attribute = $data['attribute'];

        $this->acmeProductFacade->save($productId, $acmeProductData);
    }

    public function removeData($productId)
    {
        $this->acmeProductFacade->remove($productId);
    }
}

Demo Data

In order to enable easy testing or to demonstrate usage of your plugin, you might want to provide demonstrational data with it. In that case, you should implement PluginDataFixtureInterface that will take care of loading demonstrational data into the core.

All you got to do is to implement PluginDataFixtureInterface::load() method and tag the service in a DI container with shopsys.data_fixture tag.

Example

services:
    acme.acme_bundle.data_fixture:
        class: AcmePlugin\AcmeDataFixture
        tags:
            - { name: shopsys.data_fixture }

class AcmeDataFixture implements PluginDataFixtureInterface
{
    private $acmeProductFacade;

    public function __construct(AcmeProductFacade $acmeProductFacade) {
        $this->acmeProductFacade = $acmeProductFacade;
    }

    public function load() {
        $firstAcmeProductData = new AcmeProductData();
        $firstAcmeProductData->enableWeightCalculation = true;
        $firstAcmeProductData->weight = 42;
        $firstAcmeProductData->domainId = 1;

        $this->acmeProductFacade->save($firstAcmeProductData);

        $secondAcmeProductData = new AcmeProductData();
        $secondAcmeProductData->enableWeightCalculation = false;
        $secondAcmeProductData->weight = null;
        $secondAcmeProductData->domainId = 2;

        $this->acmeProductFacade->save($secondAcmeProductData);
    }

}

CRON modules

When your plugin needs to execute some task periodically, for example downloading currency exchange rates every six hours, you can use a CRON module.

There are 2 types of CRON module interfaces:

• SimpleCronModuleInterface
  • for short tasks that do not take too long to execute
• IteratedCronModuleInterface
  • for long-running tasks that can be divided into smaller parts
  • if the module takes too long to run it will be suspended and will be woken up and re-run during the next opportunity

You can implement either one of these interfaces and tag the service in a DI container with shopsys.cron tag.

CRON modules are started automatically every time the current system time matches the specified mask in the tag attributes hours and minutes.

Example

acme.data_download_cron_module:
    class: AcmePlugin\AcmeDataDownloadCronModule
    tags:
        - { name: shopsys.cron, hours: '*/6', minutes: '0' }

// ...
class AcmeDataDownloadCronModule implements SimpleCronModuleInterface
{
    /**
     * @var \Symfony\Bridge\Monolog\Logger
     */
    private $logger;

    public function setLogger(Logger $logger)
    {
        $this->logger = $logger;
    }

    public function run()
    {
        $data = $this->downloadData();
        $this->saveData($data);

        $this->logger->info(sprintf('Downloaded %d new records.', count($data)));
    }

    // ...
}

How to implement a plugin

Plugins are implemented in a form of a Symfony bundle. For tips on how to write a new bundle see Best Practices for Reusable Bundles.
