Question

我想请你帮忙。我不是一个严格的编码人员，所以我无法构建执行此操作的正确代码。

我有一个订单付款应用程序，可以保存某些订单的付款。那里没有问题。数据正在保存在 ORDER_PAYMENTs 表中。

在我的创建函数中，我有这个

public function create($order_id)
{

    $order = Orders::find($order_id);
    $order->company;
    $order->currency;
    $banks = Banks::all('name','acronym','id')->pluck('name','id')->all();
    $balance = Orderpayments::where('order_id', '=', $order_id)->sum('amount');
    // dd($balance);
    return view('orderPayments.create', compact('balance'))
               ->with('banks', $banks)
               ->with('order', $order);
}

变量 $ balance 进行总金额的计算，然后在create.blade中进行实际计算，以检查是否还有余额。这是它的样子

    <div class="form-group">
        <span><strong>Remaining Balance</strong></span>
        <p class="text-danger">@php $remainingBalance = $order->grandtotal-$balance; @endphp
        {{ number_format($remainingBalance, 2) }}</p>                           
</div>

现在，我要做的是根据存储数据（我指的是存储功能）做出一个条件，即如果付款涵盖了所有剩余余额，则应更新该列， ORDERS 表中的 PAID 。这是我的商店功能的当前外观。

public function store(Request $request)
    {
        $this->validate($request, [
            'order_id'      => '',
            'company_id'    => '',
            'currency_id'   => '',
            'bank'          => '',
            'type'          => '',
            'payment_date'  => '',
            'amount'        => 'min:1',
            'rate'          => '',
            'bank'          => '',
            'page'          => '',
            'number'        => '',
            'booklet_number'=> '',
            'voucher_num'   => '',
            'notes'         => '',
            'user_id'       => ''
        ]);
        $orderpayments = Orderpayments::create($request->only(
            'order_id',
            'company_id',
            'currency_id',
            'bank',
            'type',
            'payment_date',
            'amount',
            'rate',
            'bank',
            'page',
            'number',
            'booklet_number',
            'voucher_num',
            'notes',
            'user_id'
        ));

        // NO IDEA ON HOW TO MAKE THE CONDITION PROPERLY
        // $balance = Orderpayments::where('order_id', '=', $order_id)->sum('amount');
        $order = Orders::all();
        // $paidOrder = $order->paid;

        dd($balance);
        // if ($balance < 1) {
        //     $amount = ;
        //     $item->save();
        // }

        if ($request){
            Session::flash('message','Purchase order was successfully added');
            Session::flash('m-class','alert-success');
        } else {
            Session::flash('message','Data is not saved');
            Session::flash('m-class','alert-danger');
            return redirect()->route('orders.index');
        }
        return redirect()->route('orders.index');
    }

首先，我正在考虑从 CREATE 函数获取$ balance变量，因为它已经具有计算能力，然后从那里检查$balance是否小于1，然后如果是将 PAID 列从 Orders表更新为“ 1”

我不是一个硬编码者，我之所以走得这么远，是因为来自各地的教程都在这里问。我找不到合适的教程来解决我的问题。您可以帮助我构建我想要实现的逻辑吗？

提前谢谢你们！

进度更新

我现在有这个

    // HERE'S THE PART THAT THE CONDITION IS PLACE
    //get the total amount paid
    $totalPaidAmount = Orderpayments::where('order_id', '=', $orderpayments->order_id)->sum('amount');
    //get the total order cost
    $orderGrandTotal = Orders::where('id', '=', $orderpayments->order_id)->get();
    //Set variable for grand total attribute Orders table
    $grandtotal = $orderGrandTotal->first()->grandtotal;
    //set variable for paid attribute in Orders table
     $paid = $orderGrandTotal->first()->paid;
    //Get the difference between  total order cost and total amount paid
    $totalBalance = $grandtotal - $totalPaidAmount;

    // dd($totalBalance);
    if ($totalBalance == 0) {
        $paid = 1;
        $paid->save();    
    }

我的新问题是，当余额达到0时，我输入的条件应保存$ paid = 1对吗？相反，我遇到了这个错误

目前，这就是我的问题。保存部分和条件。

我希望你能帮助我。在此先感谢！

已解决

以防万一，在这种情况下您会陷入自我陷阱，这就是我所做的。

    // HERE'S THE PART THAT THE CONDITION IS PLACE
    //get the total amount paid
    $totalPaidAmount = Orderpayments::where('order_id', '=', $orderpayments->order_id)->sum('amount');
    //get the total order cost
    $orderGrandTotal = Orders::where('id', '=', $orderpayments->order_id)->get();
    //Set variable for grand total attribute Orders table
    $grandtotal = $orderGrandTotal->first()->grandtotal;

    //Get the difference between  total order cost and total amount paid
    $totalBalance = $grandtotal - $totalPaidAmount;

    if ($totalBalance < 1) {
        $setToPaid = \App\Orders::where('id', '=', $orderpayments->order_id)->first();
        $setToPaid->paid = 1;
        $setToPaid->save();
    }

    if ($request){
        Session::flash('message','Purchase order was successfully added');
        Session::flash('m-class','alert-success');
    } else {
        Session::flash('message','Data is not saved');
        Session::flash('m-class','alert-danger');
        return redirect()->route('orders.index');
    }
    return redirect()->route('orders.index');

从docs

 // HERE'S THE PART THAT THE CONDITION IS PLACE
//get the total amount paid
$totalPaidAmount = Orderpayments::where('order_id', '=', $orderpayments->order_id)->sum('amount');
//get the total order cost
//$orderGrandTotal = Orders::where('id', '=', $orderpayments->order_id)->get();
$orderGrandTotal = Orders::find($orderpayments->order_id);
//Set variable for grand total attribute Orders table
$grandtotal = $orderGrandTotal->grandtotal;
//set variable for paid attribute in Orders table
 $paid = $orderGrandTotal->paid;
//Get the difference between  total order cost and total amount paid
$totalBalance = $grandtotal - $totalPaidAmount;

// dd($totalBalance);
if ($totalBalance == 0) {
    $orderGrandTotal->paid = 1;
    $orderGrandTotal->save();    
}

我还没有测试过，但这是您想要走的方向。
