Question

我一直试图在一周内按意见栏排序获得一张桌子的前10条记录。但每次我尝试它将返回最近两三天的最高记录。这是代码

 public function TopNewPosts($cat_id = null)
{
    $where = "";
    if(!is_null($cat_id))
        $where = " where postha.`cat_id` = '".$cat_id."'";

    $sql = "select postha.`id` as post_id, postha.`title`, postha.`time`, 
    postha.`cat_id`, postha.`views`,
    postha.`likes`, postha.`img` as post_img, `post_cats`.`img` as cat_img, 
    `post_cats`.`name` as cat_name from
    (select * from `posts` where `posts`.`time` > ".time()."-604800 order by 
    `time` desc limit 10) as postha
     inner join `post_cats` on postha.`cat_id` = `post_cats`.`id`
    $where
     order by `views` desc";
    $query = $this->conn->query($sql);

    return $query->fetchAll(PDO::FETCH_ASSOC);
     }

这是表格架构

id int（11）NO PRI auto_increment
title varchar（255）没有文字龙文字没有 time varchar（15）没有 cat_id int（11）没有 views int（11）没有喜欢int（11）没有 img varchar（20）NO default.png
