站长朋友们在使用的过程中，是否曾经遇到这样的问题：希望在新发布的（24小时内发布的）文章前面添加new这种特殊标记？这篇WordPress教程里，91wordpress就向大家介绍一下具体的操作方法。
1. 切换到主题目录，打开functions.php文件，加入以下代码：
post_date;
$time = get_post_time('G',true,$post);
$time_diff = time() - $time;
if ( $time_diff > 0 && $time_diff < 24*60*60 ){
$display = '';
}else{
//$display = '';
}
return $display;
}
?>
'
代码解释：此处代码代表给24小时内（< 24*60*60）发布的文章添加new特殊标记。如果更长时间，请自己修改上面的代码。
2. 在需要显示new的分类或者首页的列表页面的单篇文章的循环里添加如下代码：
以category.php文件输出当前分类的文章列表为例，完整的代码如下：
Crayon-main" style="">Crayon-table">
| Crayon-nums " data-settings="show"> Crayon-nums-content" style="font-size: 12px !important; line-height: 15px !important;"> Crayon-code">Crayon-num" data-line="Crayon-5c891cfe4f563283568781-1">1 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-3">3 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-5">5 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-7">7 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-9">9 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-11">11 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-13">13 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-15">15 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-17">17 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-19">19 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-21">21 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-23">23 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-25">25 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-27">27 Crayon-num" data-line="Crayon-5c891cfe4f563283568781-29">29 Crayon-pre" style="font-size: 12px !important;
