I have an ACF checkbox on woocommerce categories homepage_featured and am trying to get a list of all categories which have this checkbox ticked. I have tried using the below code but have had no luck:

function shortcode_handler() {
      $output;

      $args = array(
        'taxonomy' => 'product_cat',
        'hide_empty' => 0
      );
      $c = get_categories($args);
      $c_keep = array();
      foreach($c as  $cat){
        if (get_field('homepage_featured', 'category_'.$cat->term_id)) {
          $c_keep[] = $cat; // forgot [] here
        }
      }

      foreach($c_keep as $cat){
        $ouput .= $cat->name;
      }

      return $output;
     }
    add_shortcode('featured_categories','shortcode_handler');
