/*** Notes:消费记录* Date: 2019/6/25* Time: 15:43* @param Request $request* @return \think\response\Json*/public function getMyConsumeLog(Request $request){ global $_W; $size = $request->param('size', 6); $list = $this->model->getListByMid($_W['user']['id'],$size); return json(['data' => $list, 'error' => 0, 'message' => 'success']);}public function getListByMid($mid,$size = 10){ $res = $this ->alias('c') ->field('c.*,b.book_name,b.book_flash,s.section_title') ->leftJoin('booksection s','c.chapter_id = s.id') ->leftJoin('book b','s.book_id = b.id') ->where('c.mid',$mid) ->order('c.id desc') ->paginate($size); return $res;} |
返回数据
{
"data": {
"total": 1,
"per_page": 1,
"current_page": 1,
"last_page": 1,
"data": [
{
"id": 105,
"mid": 55,
"book_id": 31,
"chapter_id": 46046,
"score": 27,
"create_time": 1561447448,
"book_name": "桃运村支书",
"book_flash": "https://cdnxiaoshuo.t.com/FiO6TM0N4kpzKB7tqrDko64ZS4H4",
"section_title": "第29章 康庄大道"
}
]
},
"error": 0,
"message": "success"
}
方法二
利用limit方法

$curr_page = $request->param('page', 1); $size = $request->param('size', 6);$list = $consume_model->getListByWhere($curr_page, $size, $where); $num = $consume_model->getListByWhereCount($where); return json(['data' => $list,'num' => $num,'error' => 0, 'message' => 'success']);public function getListByWhere($curr_page,$limit = 10,$where = null){ $res = $this ->alias('c') ->field('c.*,b.book_name,s.section_title') ->leftJoin('booksection s','c.chapter_id = s.id') ->leftJoin('book b','s.book_id = b.id') ->where($where) ->order('c.id desc') ->limit($limit*($curr_page - 1),$limit) ->select() ->toArray(); return $res;}public function getListByWhereCount($where = null){ $count = $this ->alias('c') ->where($where) ->count(); return $count;} |
返回值
{
"data": [
{
"id": 2,
"mid": 4,
"book_id": 4,
"chapter_id": 22,
"score": 30,
"create_time": 0,
"book_name": "复仇者联盟I",
"section_title": "第11章 你是睡"
},
{
"id": 1,
"mid": 4,
"book_id": 29,
"chapter_id": 34,
"score": 20,
"create_time": 1598999,
"book_name": "复仇者联盟II",
"section_title": "第11章 你是睡"
}
],
"num": 2,
"total_coin": 50,
"error": 0,
"message": "success"
}
希望本文所述对大家基于ThinkPHP框架的PHP程序设计有所帮助。
