Laravel增删改查公用方法

1.在Controller文件夹下创建GetwayController.php文件（可自定义controller下任意位置及文件名）

selects($data);  //查询方式
                break;
            case 'POST' :
                return $insert->inserts($data);  //新建
                break;
            case 'DELETE' :
                return $update->deleteds($data);  //删除
                break;
            case 'PATCH' :
                return $update->updateds($data);  //修改
                break;
            default:
                return $select->selects($data);
                break;
        }
    }
}

2.在App\Models\Processdata文件夹下创建一下文件
Insert.php

insert($data);

      return response()->json(['code'=>200,'message'=>'添加成功','data'=>'','success'=>true]);
  }

  public function inserts($data){
      $table = $data['table'];
      $data['created_at'] = date('Y-m-d H:i:s');
      $data['updated_at'] = date('Y-m-d H:i:s');
      $unset = ['table','relations','key_words','_token','copy','id'];
      foreach($unset as $k){
          unset($data[$k]);
      }
//        dd($data);
      $result = DB::table($table)->insert($data);
//        dd($result);
      if(!$result){
          return '添加失败';
      }
      return '添加成功';
  }

}

Select.php

$vo){
            if(array_key_exists($vo,$data)){
                $info[$vo] = $data[$vo];
                unset($data[$vo]);
            }
        }
        $data = array_filter($data);
        $field = null;
        if(!empty($info['datetime'])){
            $datetime = explode(",",$info['datetime']);
        }
        if(!empty($info['order'])){
            $order = explode(",",$info['order']);
        }
        $where = [];
        if(isset($data['like'])){
            $where[] = $data['like'];
            unset($data['like']);
        }
        if(!empty($info['field'])){
            $field = explode(",",$info['field']);//转换成数组
        }
        foreach ($data as $k=>$v){
            count($data) != 0 && $where[] = [$k,$v];
        }
        $result = DB::table($info['table'])->where($where)->orderBy('id','desc')->get($field);
        if(!empty($order)){
            $result = DB::table($info['table'])->where($where)->orderBy($order[0],$order[1])->orderBy('id','desc')->get($field);
        }
        if(!empty($datetime[1]) && !empty($datetime[2])){
            $datetime[1] = $datetime[1]." 00:00:00";
            $datetime[2] = $datetime[2]." 23:59:59";
            $result = DB::table($info['table'])->where($where)->whereBetween($datetime[0],[$datetime[1],$datetime[2]])->orderBy('id','desc')->get($field);
            if(!empty($order)){
                $result = DB::table($info['table'])->where($where)->whereBetween($datetime[0],array($datetime[1],$datetime[2]))->orderBy($order[0],$order[1])->orderBy('id','desc')->get($field);
            }
        }
        return $result;
    }

}

Update.php

where($info)->update($data);
        if($result){
            $msg = '修改成功';
        }else{
            $msg = '修改失败';
        }
        if(!empty($delete)){
            if($result){
                $msg = '已删除';
            }else{
                $msg = '删除失败';
            }
        }
        return $msg;
    }

    public function deleteds($data){
        $table = $data['table'];
        $unset = ['table','_method','relations','key_words','_token','delete','copy'];
        foreach($unset as $k){
            unset($data[$k]);
        }
        $result = DB::table($table)->where($data)->delete();
//        dd($result);
        if($result == 0){
            return '删除失败';
        }
        return '已删除';
    }

}

3.调用
引入

use App\Http\Controllers\Home\GetwayController;

使用

$data = $request->all();
$data['table'] = 'pro_classify';
$result=GetwayController::forway($data,'GET');
$result=$result[0];


if(!empty($request->all())) {
            $data = $request->all();
            $data['table'] = 'pro_classify';

            //执行添加
            if(empty($data['id'])){
                $result=GetwayController::forway($data,'POST');

                return response()->json(['message'=>'添加成功','error'=>0,'data'=>$result]);
            }else{
                // dd($data);
                if($data['pid'] != '0'){
                    if(!empty($data['hide'])){
                        $data['hide'] = '2';
                    }else{
                        $data['hide'] = '1';
                    }
                }
                // dd($data);
                //执行修改
                $result=GetwayController::forway($data,'PATCH');
                return response()->json(['message'=>'修改成功','error'=>0,'data'=>$result]);
            }

        }
