특정 기간 내의 WordPress 기사 수

wordpress某段时间内的文章数，具体效果可以到无冷博客查看

1. function num_posts($days=1) {//$days就是设定时间一天；
2. global $wpdb;
3. $today = gmdate('Y-m-d H:i:s', time() 3600 * 8);//获取当前的时间
4. $daysago = date( "Y-m-d H:i:s", strtotime($today) - ($days * 24 * 60 * 60) ); //Today - $days
5. $result = $wpdb->get_results("SELECT ID FROM $wpdb->posts WHERE post_date BETWEEN '$daysago' AND '$today' AND post_status='publish' AND post_type='post' ORDER BY post_date DESC ");
6. foreach ($result as $Item) {
7. $post_ID[] = $Item->ID;//已发布的文章ID，写到一个数组里面去
8. }
9. $post_num = count($post_ID);//输出数组中元素个数，文章ID的数量，也就是发表的文章数量
10. $output .= ''.$post_num.'';//输出文章数量
11. echo $output;
12. }
