我正在尝试直接从 phpbb3 数据库中检索特定用户的未读帖子总数。我正在使用 ezsql 让我的生活更轻松，我根据以下帖子编写了以下代码：https ://www.phpbb.com/community/viewtopic.php?f=46&t=2107403#p12881167

$unreadposts 似乎总是返回一个高于实际未读帖子数的数字。在过去的 12 个小时里，我一直在研究这个，它把我的头发扯掉了：）

任何帮助或建议将不胜感激！

        // Step 1: get all topics the user has access to. Assuming all of them are unread until we prove otherwise
        $usertopicsallowed = $forumdb->get_results("SELECT DISTINCT t.topic_id, t.forum_id, t.topic_last_post_time FROM $forumdbname.phpbb_users u

好的，正如我在上面的评论中所说，在 12 小时未能使其正常工作后，我在此处发布后的 15 分钟内找到了答案！注意到这个回复，所以也许它会在未来对其他人有所帮助，我也会在链接上回复。

这个链接给出了答案（https://www.phpbb.com/community/viewtopic.php?f=46&t=2092813#p12800435）但不允许权限，所以你需要添加我在下面写的代码. 因此完整的代码是：

// Step 1: get all topics the user has access to. Assuing all of them are unread until we prove otherwise
        $usertopicsallowed = $forumdb->get_results("SELECT DISTINCT t.topic_id, t.forum_id, t.topic_last_post_time FROM $forumdbname.phpbb_users u 
        INNER JOIN  $forumdbname.phpbb_user_group ug ON u.user_id = ug.user_id
        INNER JOIN  $forumdbname.phpbb_groups g ON g.group_id = ug.group_id
        INNER JOIN  $forumdbname.phpbb_acl_groups acl ON acl.group_id = ug.group_id
        INNER JOIN  $forumdbname.phpbb_forums f ON f.forum_id = acl.forum_id
        INNER JOIN  $forumdbname.phpbb_topics t ON f.forum_id = t.forum_id
        WHERE u.user_id = " . $forumuserid . ";");

        // Step 2: Calculate unread posts in all forums (regardless of permissions)         
        $phpbbv2 = $forumdb->get_results("SELECT t.topic_id, t.topic_last_post_time, tt.mark_time as topic_mark_time, ft.mark_time as forum_mark_time FROM (phpbb_topics t) 
        LEFT JOIN phpbb_topics_track tt ON (tt.user_id = " . $forumuserid . " AND t.topic_id = tt.topic_id) 
        LEFT JOIN phpbb_forums_track ft ON (ft.user_id = " . $forumuserid . " AND t.forum_id = ft.forum_id) 
        WHERE ( (tt.mark_time IS NOT NULL AND t.topic_last_post_time > tt.mark_time) 
        OR (tt.mark_time IS NULL AND ft.mark_time IS NOT NULL AND t.topic_last_post_time > ft.mark_time) 
        OR (tt.mark_time IS NULL AND ft.mark_time IS NULL AND t.topic_last_post_time > " . $forumuserlastmark . ") ) AND t.topic_moved_id = 0 AND t.topic_approved = 1 ORDER BY t.topic_last_post_time DESC;");

        // Step 3: Loop through step 2 and only increment the counter for every topic the user has permission to view
        $unreadcounter=0;
        if (!empty($phpbbv2))
        {
            foreach($phpbbv2 as $key => $phpbbv2a)
            {
                if (!empty($usertopicsallowed))
                {
                    foreach($usertopicsallowed as $key2 => $usertopicallowed)
                    {
                        if ($phpbbv2[$key]->topic_id == $usertopicsallowed[$key2]->topic_id)
                        {
                            $unreadcounter++;
                        }   
                    }
                }
            }
        }
        $unreadpost=$unreadcounter;

我相信它可能会更好，我不是最有经验的 php，但它为我工作。
