Accessing data provider via PHP

Catalog Data Provider Service

Example usage in Controller or services:

/** @var $catalogService \Silversolutions\Bundle\EshopBundle\Services\Catalog\CatalogDataProviderService */
$catalogService = $this->get('silver_catalog.data_provider_service');

/** @var $catalogElement \Silversolutions\Bundle\EshopBundle\Catalog\CatalogElement */
/* Get product by Url/Request */
$catalogElement = $catalogService->getDataProvider()->lookupByUrl($urlService->getSeoUrl($request), $ezHelper->getCurrentLanguageCode()); 
/* Get product by sku  */
$catalogElement = $catalogService->getDataProvider()->fetchElementBySku(
    $productNodeSku,
    array()
);

This service injects different data providers to the Catalog Service using external configuration. You can choose the provider depending on SiteAccess, URL, etc.

Implementation

To choose the proper catalog provider, use tags and compiler pass.

Compiler pass

New compiler pass (CatalogDataProviderOperationsPass) collects all services which are tagged with catalog_data_provider_operation. For example:

<tag name="catalog_data_provider_operation" alias="ez5" />

The compiler pass calls setDataProviderService from CatalogDataProviderService and sets all available providers.

When the actual call to catalog data provider service is made, the proper provider is chosen depending on the SiteAccess.

/**
* Array, which holds the catalog data providers services as dependencies.
*
* @var CatalogDataProvider[]
*/
protected $dataProviders;

...

public function getDataProvider()
{
    // return the data provider by SiteAccess
    return $this->dataProviders[$this->configResolver->getParameter('catalog_data_provider', 'silver_eshop')];
}
