Php 更新Laravel中的父记录时更新子记录

我有一个“装运”模型和一个子模型“

shipping\u details

”，我创建了一个编辑表单，如果我要编辑整个装运，我希望能够对

装运\u details

进行更新

目前，这是我的“装运”模型：

这是我的编辑页面更新控制器：

public function updateRecord(Request $request, $id)
    {

      $shipment = Shipment::where('UUID','=',$id)->firstOrFail();

        //Save Initial Shipment Data
        $shipment->pro_number = request('pro_number');
        $shipment->shipment_origin = request('shipment_origin');
        $shipment->date = request('date');
        $shipment->due_date = request('due_date');
        $shipment->tractor_id = request('tractor_id');
        $shipment->trailer_id = request('trailer_id');
        $shipment->driver_id = request('driver_id');
        $shipment->notes = request('notes');

        $shipment->bill_to = request('bill_to');
        $shipment->bill_type = request('bill_type');
        $shipment->load_date = request('load_date');
        $shipment->shipment_status = 1;
        $shipment->shipment_billing_status = (isset($request->shipment_billing_status) && !empty($request->shipment_billing_status)) ? $request->shipment_billing_status : 1;
        $shipment->cn_billtoName = request('cn_billtoName');
        $shipment->cn_billtoAddress1 = request('cn_billtoAddress1');
        $shipment->cn_billtoAddress2 = request('cn_billtoAddress2');
        $shipment->cn_billtoCity = request('cn_billtoCity');
        $shipment->cn_billtoState = request('cn_billtoState');
        $shipment->cn_billtoZip = request('cn_billtoZip');
        $shipment->cn_billtoEmail = request('cn_billtoEmail');
        $shipment->cn_billtoPhone = request('cn_billtoPhone');
        $shipment->cn_shiptoName = request('cn_shiptoName');
        $shipment->cn_shiptoAddress1 = request('cn_shiptoAddress1');
        $shipment->cn_shiptoAddress2 = request('cn_shiptoAddress2');
        $shipment->cn_shiptoCity = request('cn_shiptoCity');
        $shipment->cn_shiptoState = request('cn_shiptoState');
        $shipment->cn_shiptoZip = request('cn_shiptoZip');
        $shipment->cn_shiptoEmail = request('cn_shiptoEmail');
        $shipment->cn_shiptoPhone = request('cn_shiptoPhone');
        $shipment->cn_shipfromName = request('cn_shipfromName');
        $shipment->cn_shipfromAddress1 = request('cn_shipfromAddress1');
        $shipment->cn_shipfromAddress2 = request('cn_shipfromAddress2');
        $shipment->cn_shipfromCity = request('cn_shipfromCity');
        $shipment->cn_shipfromState = request('cn_shipfromState');
        $shipment->cn_shipfromZip = request('cn_shipfromZip');
        $shipment->cn_shipfromEmail = request('cn_shipfromEmail');
        $shipment->cn_shipfromPhone = request('cn_shipfromPhone');
        $shipment->fuelChargeDesc = request('fuelChargeDesc');
        $shipment->fuelChargeAmt = request('fuelChargeAmt');
        $shipment->fuelChargeTotal = request('fuelChargeTotal');
        $shipment->permitChargeDesc = request('permitChargeDesc');
        $shipment->permitChargeAmt = request('permitChargeAmt');
        $shipment->permitChargeTotal = request('permitChargeTotal');
        $shipment->otherChargeDesc = request('otherChargeDesc');
        $shipment->otherChargeAmt = request('otherChargeAmt');
        $shipment->otherChargeTotal = request('otherChargeTotal');
        $shipment->noCharge = request('noCharge');
        $shipment->noSettle = request('noSettle');
        $shipment->Total = request('Total');
        if ((request('shipment_billing_status') == 2) || (request('shipment_billing_status') == 3)){
           $balance = 0.00;
        }else{
           $balance = request('Total');
        }
        $shipment->Balance = $balance;
        $shipment->freightBillSubtotal = request('freightBillSubtotal');

        $shipment->save();

        //Save Shipment Details -- NEED HELP HERE //

           for ($i = 0; $i < count($request->shipment_details['piecesNumber']); $i++) {

            $Shipment_Detail = Shipment_Detail::where
            Shipment_Detail::create([
                'shipment_id' => $shipment->pro_number,
                'pieces_number' => $request->shipment_details['piecesNumber'][$i],
                'pieces_type' => $request->shipment_details['piecesType'][$i],
                'rate_type' => $request->shipment_details['rateType'][$i],
                'charge' => $request->shipment_details['charge'][$i],
                'weight' => $request->shipment_details['weight'][$i],
                'hazmat' => $request->shipment_details['hazmat'][$i],
                'description' => $request->shipment_details['description'][$i] ]);
        }

        //END HELP HERE SECTION//


        Session::flash('success_message','Freight Bill Successfully Updated'); //<--FLASH MESSAGE

        //Return to Register//
        return redirect('/shipments/i/'.$shipment->UUID);

    }

通过控制器使用以下命令将

装运详细信息

拉到页面：

$shipment_details = $shipment->shipment_details;

更新对答案的回应 我现在使用以下命令将详细信息保存在我的

装运

控制器中：

        foreach ( $request->shipment_details as $id => $details ) {
            $shipdetail = Shipment_Detail::find($id);
            $shipdetail->pieces_type = $details->piecesType;
            $shipdetail->pieces_number = $details->piecesNumber;
            $shipdetail->rate_type = $details->rateType;
            $shipdetail->weight = $details->weight;
            $shipdetail->charge = $details->charge;
            $shipdetail->description = $details->description;
            $shipdetail->hazmat = $details->hazmat;
            // Other info to update here
            $shipdetail->save();
        }

和我的html表单：

@foreach($shipment_details as $sd)
                        <tr style="height:40px">
                            <td style="width:8%;text-align:center;">{{Form::text('shipment_details['.$sd->id.'][piecesNumber]', $sd->pieces_number, array('class' => 'form-control','placeholder'=>'No. Pieces','required','id'=>'piecesNumber'))}}

                            <td style="width:16.5%;text-align:center;">

                </tr>

                    @endforeach

由于记录已经存在，我们可以稍微修改您的HTML，将适当的ID放入HTML中，以传递给控制器。您的每个现有输入都需要从

{{Form:：select（'shipping_details[piecesType][]，…）}

到

{Form:：select（'shipping_details['.$sd->id.][“piecesType”]，…）}

在控制器中，这为我们提供了一个示例：

shipping\u详细信息[2]['piecesType']//等于某个值

现在，对于控制器，我们可以使用：

foreach ( $request->shipment_details as $id => $details ) {
    $shipdetail = Shipment_Details::find($id);
    $shipdetail->piecesType = $details['piecesType'];
    // Other info to update here
    $shipdetail->save();
}

它将取代当前的
