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 [];
}
}
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{

}
}

}
}

public function buy_num($uid){
