Czy istnieje lepszy sposób na uzyskanie nazw kategorii dla niestandardowego typu postu w wordpress?

<?php        // get the portfolio categories
            $terms = get_the_terms( $post->ID, 'filters' );                           
            if ( $terms && ! is_wp_error( $terms ) ) : 
                $names = array();
                $slugs = array();
                foreach ( $terms as $term ) {
                 $names[] = $term->name;
                 $slugs[] =  $term->slug;
                }                                
                $name_list = join( " / ", $names );
                $slug_list = join( " category-", $slugs );
        endif;
    ?>


    <!-- BEGIN portfolio-item-->
    <li class="portfolio-item third column category-<?php echo $slug_list; ?>" data-filter="category-<?php echo $slug_list; ?>">
