Question

我正在构建一个聊天框，从设置页面中提取评论。它实时更新。

那么我如何获得最近50条评论，但排除我已经显示的评论？ get_comments（）不允许我排除评论。

这是我希望能够做到的：

// Array of already displayed comment id's
$exclude = array(10, 22, 41, 80);

$args = array (
    'number'   => 50,
    'user_id'  => $user_ids,
    'post_id'  => 57,
    'status'   => 'approve',
    'order'    => 'DESC',
    'exclude'  => $exclude
);
$comments = get_comments( $args );

任何人都知道实现“排除”参数的方法，或类似的东西？

您可以使用wpdb类

尝试原始sql查询

SELECT 
  * 
FROM
  `wp_comments` 
WHERE `comment_approved` = 1 
  AND `comment_post_ID`=57 
  AND `user_id` IN (0, 1, 2)
  AND comment_ID NOT IN (10, 22, 41, 80)
  ORDER BY  comment_date DESC
  LIMIT 50

使用wpdb

global $wpdb
$sql="SELECT 
  * 
FROM
  $wpdb->comments 
WHERE `comment_approved` = 1 
  AND `comment_post_ID`=57 
  AND `user_id` IN (". join(',',$user_ids) .")
  AND comment_ID NOT IN (". join(',',$exclude) .")
  ORDER BY  comment_date DESC
  LIMIT 50";
$comments=$wpdb->get_results($sql);


if(!empty($comments)){
foreach($comments as $c){
$single_comment=get_comment( $c->comment_ID);
}
}
