I tried following this: https://searchandfilter.com/documentation/accessing-search-data/

on this page: http://staging2.iconcasterwheels.com/shop/?_sfm_caster-wheel-size=10%22&_sfm_caster-wheel-material=Air%2FFlat%20Free&_sfm_caster-fastening-type=Top%20Plate&_sfm_caster-load-capacity=200+300

Here is the code:

global $searchandfilter;
	  $sf_current_query = $searchandfilter->get(56)->current_query();
      //var_dump($sf_current_query->get_array());

      $searchArgs = array(
        "str" 					=> '%2$s', 
        "delim" 				=> array(", ", " - "), 
        "field_delim"			=> ', ', 
        "show_all_if_empty"		=> false 
      );
	  
      
      echo $sf_current_query->get_fields_html(
        array(
          "_sfm_caster-wheel-size",
          "_sfm_caster-wheel-material",
          "_sfm_caster-fastening-type",
          "_sfm_caster-load-capacity"
        ), 
        $searchArgs
      );

When I do a var_dump, it shows the info that is expected (hidden for now) — so the id and everything seems to be correct.
However, when I try to display any of the field values, nothing shows up.

No errors in console message or anything either.

I am trying to get it to say “Search Results 10″, Air Flat/Free, Top Plate”
