Question

我已经制作了一个用于搜索帐单号的表格。在数据库表中找到帐单后，数据应显示在标签中。我怎样才能做到这一点？然后，用户按下按钮以支付账单金额。

视图块

<form class="form-horizontal" method="POST" action="{{action('OrderedBookController@billPay')}}" enctype="multipart/form-data">
                        {{ csrf_field() }}
                <div class="row" style="padding-left: 1%;">
                        <div class="col-md-4">
                            <div class="form-group">
                                <label>Bill Number</label><span class="required">*</span>
                                <input type="text" maxlength="15" required="required" autofocus="autofocus" autocomplete="off" name="NBillNumber" class="form-control"/>                                
                            </div> 
                        </div> 
                        <div class="col-md-4">
                            <div class="form-group"></div> 
                            <div class="form-group" style="padding-left: 5%;">
                                <button type="submit" class="btn btn-primary">Search</button>        
                            </div> 
                        </div>                      
                </div>
</form>

<div class="row" style="padding-left: 1%;">
        <div class="col-md-4">
            <div class="form-group">
                <label>Book ID</label>
                <output name="NBookID" class="form-control" aria-readonly="true"/> 
            </div>
            <div class="form-group">
                    <label>Billed Date</label>
                    <output name="NBilledDate" class="form-control" aria-readonly="true"/>
            </div>
        </div>
        <div class="col-md-4" style="padding-left: 3%;">
            <div class="form-group">
                    <label>Billed Number</label>
                    <output name="NBilledNumber" class="form-control" aria-readonly="true"/>
            </div>
            <div class="form-group">
                <label>Quantity</label>
                <output name="NBilledQuantity" class="form-control" aria-readonly="true"/>
            </div>  
        </div>
        <div class="col-md-4"style="padding-left: 3%;">
            <div class="form-group">
                <label>Price</label>
                <output name="NBilledPrice" class="form-control" aria-readonly="true"/>
            </div>
            <div class="form-group">
                <label>Remarks</label>
                <output name="NBilledRemarks" class="form-control" aria-readonly="true"/>
            </div>
            <div class="form-group">
                    <button type="submit" class="btn btn-primary">PAY</button>        
            </div> 
        </div>
</div>

OrderedBookController代码块

public function searchBill()
    {
        return view ( 'pages.payBill');
    }

public function billPay(Request $request)
    {
        $billNum = $request->input('NBillNumber');

        if($billNum != ""){
            $billsrch = OrderedBook::where ( 'BilledNum', $billNum )->get ();
            if (count ( $billsrch ) > 0)
            {
                return response()->json($billsrch);
                return view('pages.payBill', compact('billsrch'));
            }                
            else
            {
                return view ( 'pages.payBill',compact('billsrch'))->with('alert-danger', 'Sorry No details found');
            }

        }
    }

在调试billPay方法时，我正在从数据库中获取数据。然后如何在我的视图块中显示数据。在以前的表格中，我将数据显示在表格中，但是现在我需要在表格中显示数据，并在按下按钮PAY时更新付费列。我该怎么办？

路线代码块

Route::get('/billSearch','OrderedBookController@searchBill');
Route::post('/billPay','OrderedBookController@billPay');

您必须基于这样的条件显示html。 如果您的表单是post方法，则应通过ajax处理。 如果您的表单是get方法，只需输入这样的条件即可。

@if ($billsrch)
<form class="form-horizontal" method="POST" action="{{action('OrderedBookController@billPay')}}" enctype="multipart/form-data">
                        {{ csrf_field() }}
                <div class="row" style="padding-left: 1%;">
                        <div class="col-md-4">
                            <div class="form-group">
                                <label>Bill Number</label><span class="required">*</span>
                                <input type="text" maxlength="15" required="required" autofocus="autofocus" autocomplete="off" name="NBillNumber" class="form-control"/>
