How to get products from the product stream ID in Shopware 6?

Question

I am trying to create a custom command in which I want to utilize the Dynamic Product Group feature of Shopware 6 to fetch the products which match the filters in a specific product group (a.k.a product streams).

I am doing this to fetch the streams initially, but I am lost as to how to apply the filters to fetch the products.

            $streamCriteria = new Criteria($productStreamIds);
            $streamCriteria->addAssociation('productCrossSellings');
            $streamCriteria->addAssociation('productExports');
            $streamCriteria->addAssociation('filters');

            $streams = $this->streamRepository->search($streamCriteria, $context)->getEntities();
            /** @var ProductStreamEntity $stream */
            foreach ($streams as $stream) {
                foreach ($stream->getFilters() as $filter) {
                    $productCriteria->addAggregation($filter); // DOES NOT WORK
                    $productCriteria->addFilter($filter); // DOES NOT WORK EITHER
                }
            }

I tried to get the filters which gives me the array of filters that are applied in the product stream, but it is not directly applicable to the criteria->addFilter() due to different expected types.

This is the filters array that I get:

}

The productCrossSellings and productExports associations are all returning null as well (although I do not know what is the use of these variables, but I thought maybe it is being used somehow internally to get the associated products for that group).

So my question is, that how do we get the products that match the filters in a product group ?

Answer 1

You can check \Shopware\Core\Content\ProductStream\Service\ProductStreamBuilder and how it is used in \Shopware\Core\Content\Product\SalesChannel\CrossSelling\SalesChannelCrossSellingController::loadProductsForCrossSelling

I hope it would be helpful.
