Question

我正在尝试从csv文件上传数据。将数据导入数据库表时，值为NULL。我的CSV文件有价值。

我通过安装Maatwebsite \ Excel来完成此过程。

我的代码

class Template extends Model
{
    protected   $fillable = ['Origin', 'OriginState', 'Destination' , 'DestinationState' , 'Carrier', 'Car' , 'Buy', 
                              'Carbon', 'DepotFrom', 'DepotTo', 'OriginType', 'DestinationType'
                            ,'GoodsAllowed', 'NonRunners', 'ETA',  'Comments', 'Disabled' ];
}



  public function upload(Request $request)
    {
        if ($request->hasFile('uploadRates')) {
            $path = $request->file('uploadRates')->getRealPath();
            $data = \Excel::load($path)->get();

            if (!empty($data) && $data->count()) {
                foreach ($data as   $value) {
                    $arr[] = ['Origin' => $value->Origin,
                              'OriginState' => $value->OriginState,
                              'Destination' => $value->Destination,
                              'DestinationState' => $value->DestinationState,
                              'Carrier' => $value->Carrier,
                              'Car' => $value->Car,
                              'Buy' => $value->Buy,
                              'Carbon' => $value->Carbon,
                              'DepotFrom' => $value->DepotFrom,
                              'DepotTo' => $value->DepotTo,
                              'OriginType' => $value->OriginType,
                              'DestinationType' => $value->DestinationType,
                              'GoodsAllowed' => $value->GoodsAllowed,
                              'NonRunners' => $value->NonRunners,
                              'ETA' => $value->ETA,
                              'Comments' => $value->Comments,
                              'Disabled' => $value->Disabled,

                             ];
                }
                if (!empty($arr)) {
                    DB::table('template')->insert($arr);
                    return "Success";
                }
            }
        }
        dd('Requested file has no Data inside.');
    }

和我的CSV数据：

来源，来源州，目的地，目的地状态，载体，汽车，购买，碳，仓库发件人，仓库目的地，来源类型，目的地类型，允许的商品，非跑步者，ETA，注释，已禁用

阿德莱德，SA，墨尔本，VIC，A1汽车运输车，汽车，250,0,0,0，仓库，仓库，0,0,5，，0 阿德莱德，SA，堪培拉，ACT，A1自动运输车，汽车609.0909091,0,0,0，仓库，仓库，0,0,7，，0 阿德莱德，SA，悉尼，新南威尔士州，A1汽车运输车，汽车409.0909091,0,0,0，仓库，仓库，0,0,7，，0 阿德莱德，SA，布里斯班，QLD，A1汽车运输车，汽车，727.2727273,0,0,0，仓库，仓库，0,0,8，，0 阿德莱德，SA，唐兹维尔，昆士兰州，A1汽车运输车，汽车，1428.181818,0,0,0，仓库，仓库，0,0,12，，0 阿德莱德，SA，凯恩斯，QLD，A1汽车运输车，汽车，1491.818182,0,0,0，仓库，仓库，0,0,14，，0

Answer 1

最可能的原因是，当您将第一行标题用作属性时，它们会显得很慢。

这意味着Origin将是$value->origin。

如果要使用原始属性，则可以将excel.php配置中的设置从import.heading更改为orginal。

编辑：我刚刚从您的评论中意识到，您的配置中已将startRow设置为2。将其更改为1。

Answer 2

if (!empty($data) && $data->count()) {
            foreach ($data as   $value) {
                Template::create(
                       ['Origin' => $value->origin,
                          'OriginState' => $value->origin,
                          'Destination' => $value->destination,
                          'DestinationState' => $value->destinationstate,
                          'Carrier' => $value->$value->carrier,
                           ...
                           ...

                         ]
                );
            }
 }

//不要忘记在模板模型中添加$ fillable属性

protected $fillable = ['Origin', 'Destination', ....]
