php - 根据上次事件对作者小部件进行排序

Question

我有一个 Wordpress 小部件，它根据帖子数列出了顶级作者。 我希望它作为最后一个事件(最后一篇文章)排序。但我不能。 我的代码是:

 "SELECT users.ID, COUNT( posts.ID ) AS post_count
  FROM {$wpdb->users} AS users
   RIGHT JOIN {$wpdb->posts} AS posts ON posts.post_author = users.ID 
   WHERE posts.post_type='post' AND posts.post_status='publish'
   GROUP BY users.ID 
   ORDER BY post_count DESC 
   LIMIT %d"`

输出:

如何根据上一篇文章对作者进行排序？

Answer 1

试试这个，我假设创建的列存在于posts表中

 "SELECT users.ID, posts.ID 
  FROM {$wpdb->posts} AS posts
    JOIN  {$wpdb->users} AS users ON posts.post_author = users.ID 
   WHERE posts.post_type='post' AND posts.post_status='publish'
   GROUP BY users.ID 
   ORDER BY posts.created DESC 
   LIMIT %d"`
