TP5框架中实现多条件登录

 控制器代码

//登录功能
    public function login(){
        $data = input();
        $validate = $this->validate($data,[
            'uname|登录账号'=>'require',//可以是账号username、手机phone、邮箱email
            'upwd|登录密码'=>'require'
        ]);
        if($validate!==true){
            return json(['code'=>1,'msg'=>$validate,'data'=>null]);
        }

        $res = User::loginSel($data);

        if(empty($res)){
            return json(['code'=>1,'msg'=>'账号密码有误','data'=>null]);
        }
        session('uid',$res['id']);
        session('unick',$res['nickname']);
        return json(['code'=>0,'msg'=>'登录成功','result'=>$res]);
    }

模型代码：

  public static function loginSel($arr){
        $username['username'] = $arr['uname'];
        $username['password'] = md5($arr['upwd']);

        $phone['phone'] = $arr['uname'];
        $phone['password'] = md5($arr['upwd']);

        $email['email'] = $arr['uname'];
        $email['password'] = md5($arr['upwd']);

        $usernameRes = self::where($username)->find();
        $phoneRes = self::where($phone)->find();
        $emailRes = self::where($email)->find();


        if($usernameRes){
            return $usernameRes;
        }

        if($phoneRes){
            return $phoneRes;
        }

        if($emailRes){
            return $emailRes;
        }

        return null;
    }

结果返回：
