本文实例讲述了Laravel框架实现model层的增删改查(CURD)操作。分享给大家供大家参考,具体如下:
protected $table = 'user_city'; public $timestamps = false; //添加 返回id public function cityadd($data) { return $this->insertGetId($data); } //单条查找 public function getfind($id) { if($this->where('id',$id)->first()){ return $this->where('id',$id)->first()->toArray(); }else{ return []; } } //查询用户有几个uid,返回数量 public function countCity($uid){ if($this->where('uid',$uid)->first()){ return $this->where('uid',$uid)->count(); }else{ return []; } } //查询全部数据 public function getAll() { return $this->get()->toArray(); } /** * 修改管理员信息 * @param $id * @param $data * @return bool */ public function upAdmin($id,$data) { if($this->find($id)){ return $this->where('id',$id)->update($data); }else{ return false; } } //加条件,时间 //查询用户的认购的城数 public function buy_num($uid){ $startDate = date('Y-m-01', strtotime(date("Y-m-d"))); $endDate = date('Y-m-d', strtotime("$startDate +1 month -1 day")); // 将日期转换为Unix时间戳 $endDate=$endDate." 22:59:59"; $startDateStr = strtotime($startDate); $endtDateStr = strtotime($endDate); return $this->where('uid',$uid)->where('buy_type',1)->whereBetween('create_time', array($startDateStr,$endtDateStr))->sum('buy_num'); } /** * 根据id查找城池信息 只返回某个字段的值 * @param $id * @return array */ public function getCityName($id) { if($this->where('city_id',$id)->first()){ return $this->where('city_id',$id)->lists('city_name')[0]; }else{ return []; } }
希望本文所述对大家基于Laravel框架的PHP程序设计有所帮助。
