Get taxonomy index

could you fix it? I have the same problem

Yes! I added this method:

public function get_city_index() {
    $cities = get_terms('cities', array( 'hide_empty' => 0 ));
	$cities_array[count($cities)];
	$i = 0;
	foreach($cities as $city){
		$cities_array[$i] = $city->slug;
		$i++;
	}
	return array(
      'count' => count($cities),
      'cities' => $cities_array
    );
  }

to the core controller, where “cities” is my taxonomy. I know the code can be optimised and all, but that did it for me. I could have returned tons of stuff in that return array, but I needed only the count and the names, so it worked OK.

my page is so,taxonomy would be my listing?
