我有一个“货件”的模型和“shipment_details”的子模型，我创建了一个编辑表单，如果我去编辑整个货件，我希望能够进行更新也是shipment_details。
目前，这是我的“发货”型号：
public function shipment_details(){
return $this->hasMany('App\Shipment_Detail', 'shipment_id','pro_number');
}
这是我的编辑页面更新的控制器：
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->shipper_no = request('shipper_no');
$shipment->ship_to = request('ship_to');
$shipment->ship_from = request('ship_from');
$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/'.$shipment->UUID);
}
在底部附近，您可以看到我已经标出了需要帮助的部分的部分。那里的代码部分取自我的存储创建页面，并且运行良好。我假设我可以在这种情况下使用它，但我不确定如何识别要更新的shipment_details以及如何将其传递给shipment_details数据库表记录中的更新。
这是我特定于与正在更新的货件相关联的shipment_details的HTML：
<tbody>
@foreach($shipment_details as $sd)
<tr style="height:40px">
<td style="width:8%;text-align:center;">{{Form::text('shipment_details[piecesNumber][]', $sd->pieces_number, array('class' => 'form-control','placeholder'=>'No. Pieces','required','id'=>'piecesNumber'))}}
</td>
<td style="width:16%;text-align:center;">
{!! Form::select('shipment_details[piecesType][]', $piecetypes, $sd->pieces_type, ['id' => 'pieces_type', 'class' => 'form-control full-width','required']) !!}
</td>
<td>
{!! Form::select('shipment_details[rateType][]', $ratetypes, $sd->rate_type, ['id' => 'rateType', 'class' => 'form-control full-width','required']) !!}
</td>
<td style="width:16.5%;text-align:center;">
{{Form::text('shipment_details[weight][]', $sd->weight, array('class' => 'form-control','placeholder'=>'Weight','required','id'=>'weight'))}}
</td>
<td style="width:16.5%;text-align:center;">
{{Form::select('shipment_details[hazmat][]',array(
'No'=>'No',
'Yes'=>'Yes',
), $sd->hazmat, array('class' => 'form-control','id'=>'hazmat'))}}
</td>
<td style="width:16.5%;text-align:center;">
{{Form::text('shipment_details[description][]', $sd->description, array('class' => 'form-control','placeholder'=>'Description','required','id'=>'description'))}}
</td>
<td style="width:16.5%;text-align:center;">
{{Form::text('shipment_details[charge][]', $sd->charge, array('class' => 'form-control','placeholder'=>'Charge','required','id'=>'charge'))}}
</td>
<td><button type="button" name="add" id="add" class="btn btn-success">Add More</button></td>
</tr>
@endforeach
</tbody>
使用以下内容将shipment_details通过控制器拉到页面：
$shipment_details = $shipment->shipment_details;
我现在使用以下内容在我的shipment控制器中保存详细信息：
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
$shipdetail->save();
}
我的html表单：
@foreach($shipment_details as $sd)
<tr style="height:40px">
<td style="width:8%;text-align:center;">{{Form::text('shipment_details['.$sd->id.'][piecesNumber]', $sd->pieces_number, array('class' => 'form-control','placeholder'=>'No. Pieces','required','id'=>'piecesNumber'))}}
</td>
<td style="width:16%;text-align:center;">
{!! Form::select('shipment_details['.$sd->id.'][piecesType]', $piecetypes, $sd->pieces_type, ['id' => 'pieces_type', 'class' => 'form-control full-width','required']) !!}
</td>
<td>
{!! Form::select('shipment_details['.$sd->id.'][rateType]', $ratetypes, $sd->rate_type, ['id' => 'rateType', 'class' => 'form-control full-width','required']) !!}
</td>
<td style="width:16.5%;text-align:center;">
{{Form::text('shipment_details['.$sd->id.'][weight]', $sd->weight, array('class' => 'form-control','placeholder'=>'Weight','required','id'=>'weight'))}}
</td>
<td style="width:16.5%;text-align:center;">
{{Form::select('shipment_details['.$sd->id.'][hazmat]',array(
'No'=>'No',
'Yes'=>'Yes',
), $sd->hazmat, array('class' => 'form-control','id'=>'hazmat'))}}
</td>
<td style="width:16.5%;text-align:center;">
{{Form::text('shipment_details['.$sd->id.'][description]', $sd->description, array('class' => 'form-control','placeholder'=>'Description','required','id'=>'description'))}}
</td>
<td style="width:16.5%;text-align:center;">
{{Form::text('shipment_details['.$sd->id.'][charge]', $sd->charge, array('class' => 'form-control','placeholder'=>'Charge','required','id'=>'charge'))}}
</td>
<td><button type="button" name="add" id="add" class="btn btn-success">Add More</button></td>
</tr>
@endforeach
我会提到这个数组在我的错误页面中，所以我知道细节实际上已被传递：
shipment_billing_status
""
shipment_details
array:1 [▼
13032 => array:7 [▼
"piecesNumber" => "1"
"piecesType" => "1"
"rateType" => "1"
"weight" => "454"
"hazmat" => "No"
"description" => "LARGE CLAM - L"
"charge" => "65.00"
]
]
freightBillSubtotal
"65.00"
答案 0 :(得分：2)
由于记录已经存在，我们可以稍微修改您的HTML，以便在HTML中获取正确的ID以传递给您的控制器。您需要从
更改每个现有输入 {{Form::select('shipment_details[piecesType][]', ..)}}
要
{{Form::select('shipment_details['.$sd->id.']["piecesType"], ..)}}
在控制器中，这给我们一个例子：
shipment_details[2]['piecesType'] // which equals some value
现在，我们可以使用控制器：
foreach ( $request->shipment_details as $id => $details ) {
$shipdetail = Shipment_Details::find($id);
$shipdetail->piecesType = $details['piecesType'];
// Other info to update here
$shipdetail->save();
}
这将取代您当前的for循环。
