- We use the
CacheInvalidatorservice provided by Shopware to invalidate cache entries. - The
removeCategoryCachemethod accepts an array of category IDs for which we want to invalidate the cache. - We utilize
CachedProductListingRoute::buildNamemethod to construct cache keys for each category ID. - Finally, we invalidate the cache for each constructed cache key using the
invalidatemethod of theCacheInvalidatorservice.
Conclusion
By implementing this solution, you ensure that the cache for category listings is properly invalidated when adding additional filters to product listings, thus resolving the issue of invalid results in the product listing.
