【网站美化】卡片列表右上角标NEW

将下面的代码放置/wp-content/themes/zibll的funtions.php中

//新文章发布角标
function add_new_label_to_post_title($title, $id) {
    if (!is_admin() && !is_single()) {
        $post_time = get_the_time('U', $id);
        if (time() - $post_time <= 24 * 60 * 60) {
            $title .= ' <div class="tianyishangke-new-icon">NEW</div>';
        }
    }
    return $title;
}
add_filter('the_title', 'add_new_label_to_post_title', 10, 2);
