        $terms = get_the_terms($post, $taxonomy);
        if ($single) {
            $term = reset($terms);
            if ($linked)
                return '<a href="' . get_term_link($term, $taxonomy) . '">' . $term->name . '</a>';
            return $term->name;
        } else {
            $output = '';
            foreach ($terms as $term) {
                if ($linked)
                    $output .= '<a class="term-item" href="' . get_term_link($term, $taxonomy) . '">' . $term->name . '</a>';
                $output .= '<span class="term-item">' . $term->name . '</span>';
            }
            $output .= '';
            return $output;
