$categories=get_the_category();echo'<ul>';echo'<li>ParentCategory:';foreach($categoriesas$category){if($category->parent!=0){$parent_category=get_term($category->parent);echo'<ahref="'.esc_url(get_category_link($parent_category->term_id)).'">'.esc_html($parent_category->name).'</a>';break;}}echo'</li>';echo'<li>Subcategory:';foreach($categoriesas$category){if($category->parent!=0){echo'<ahref="'.esc_url(get_category_link($category->term_id)).'">'.esc_html($category->name).'</a>';}}echo'</li></ul>';
