I would like to programmatically and conditionally show a facet block, if the returned values match some certain criteria. I have not found any solutions so far. For example, if a facet returns 25 apples, I would like to show an additional facet that does some calculation on this value.

If you used Search API, this code should help you:

$delta = facetapi_hash_delta(facetapi_build_delta('search_api@INDEX_MACHINE_NAME', 'block', FACET_NAME));
print render(module_invoke('facetapi', 'block_view', $delta));

  • @kenorb, it's wrong correction because as I told, my example is for search api

  • It returns an empty value with form_alter but working on tpl file. Don't know why this is happening. Sep 18, 2020 at 11:49
