WordPress后台默认是不显示文章、分类等的ID的，查看起来非常不方便，今天就分享一个非常全面的显示ID的方法，支持 文章、页面、链接、多媒体、评论、分类、标签、用户 等，也就是在这些管理页面的列表中，会添加一列 ID，如下图所示：
可以直接下载安装 Simply Show IDs 插件就可以实现该功能（虽然2年多没有更新，但是在WP 3.5.2 测试通过）。
你也可以直接将下面的代码（来自该插件）添加到当前主题的 functions.php 文件即可：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 |
