如何将多个 Child 行数据与 Parent 行一起添加到 Laravel Blade

Question

我一直在尝试通过 blade 添加多个数据。在我的 blade 表单中，我正在使用克隆，添加行。比如一个申请单有很多项目。

我的blade观点

Blade 查看代码

<form autocomplete="off" method="POST" action="{{ route("requisition.store") }}" enctype="multipart/form-data">
        @csrf
        <div class="form-group">
            <label class="required" for="purpose">Purpose</label>
            <input class="form-control" type="text" name="purpose" id="purpose" required>
            <span class="help-block"></span>
        </div>

        <div class="form-group">
            <label class="required" for="requisition_date">Date</label>
            <input class="form-control" type="date" name="requisition_date" id="requisition_date" required>
            <span class="help-block"></span>
        </div>

        <div class="form-group">
            <label class="required" for="requested_by">Released By</label>
            <input class="form-control" type="text" name="requested_by" id="requested_by" required>
            <span class="help-block"></span>
        </div>

        <table class="table table-bordered">
            <thead>
                <tr>
                    <th>Qty</th>    
                    <th>Unit</th>    
                    <th>Description</th>   
                    <th>
                        <a href="#" class="addRow"><i class="fas fa-plus"></i></a>    
                    </th> 
                </tr>
            </thead>
            <tbody>
                <tr>
                    <td>
                        <input type="number" name="rows[0][qty]" class="form-control quantity" required>  
                    </td>    
                    <td>
                        <input type="text" name="rows[0][unit]" class="form-control" required>  
                    </td>    
                    <td>
                        <input type="text" name="rows[0][description]" class="form-control" required>  
                    </td> 
                    <td>

                    </td>   
                </tr> 
            </tbody>    
        </table>



        <div class="form-group">
            <button class="btn btn-danger" type="submit">
                Save
            </button>
        </div>
    </form>

克隆脚本代码

function addRow()
{
    var tr = '<tr>'+
    '<td><input type="number" name="rows[0][qty]" class="form-control quantity"></td>'+
    '<td><input type="text" name="rows[0][unit]" class="form-control quantity"></td>'+
    '<td><input type="text" name="rows[0][description]" class="form-control quantity"></td>'+
    '<td><a class="btn btn-danger remove"><i class="fas fa-times"></i></a></td>'+
    '</tr>';
    $('tbody').append(tr);
  }

还有我的店主代码

public function store(Request $request)
{
   $requisition = Requisition::create([
            'purpose' => $request->input('purpose'),
            'requisition_date' => $request->input('requisition_date'),
            'requested_by' => $request->input('requested_by')
        ]);  

        $rows = $request->input('rows');

        foreach ($rows as $row)
        {
            $items[] = [
                'requisition_id' => $requisition->id,
                'qty' => $row['qty'],
                'unit' => $row['unit'],
                'description' => $row['description']
            ];
        }

        RequisitionItem::insert($items);

}

我的商店控制器代码中的问题是它只添加了一项而不是多项。我的模特：申请 table = 'id', 'purpose', 'requisition_date', 'requested_by', 'requisition_date' RequisitionItem table = 'id', 'requisition_id', 'qty', 'unit', 'description'

dd($行) 结果

Answer 1

我认为最简单的方法是像这样使用追加输入和 blade 输入...

name="qty[]"

而不是

name="rows[0][qty]"

并且在控制器中循环通过一个将始终被添加的字段。例如;

for($i = 0; $i < sizeof($request->qty); $i++)
    {
        RequisitionItem::insert([
            'requisition_id' => $requisition->id,
            'qty' => $request->qty[$i],
            'unit' => $request->unit[$i],
            'description' => $request->description[$i]
        ]);
    }

你也可以按照这个步骤，

  for($i = 0; $i < sizeof($request->qty); $i++)
    {
        $items[] = [
            'requisition_id' => $requisition->id,
            'qty' => $request->qty[$i],
            'unit' => $request->unit[$i],
            'description' => $request->description[$i]
        ];
    }

  RequisitionItem::insert($items);
