Php 将已验证的数组对象从插入数据库中排除

我试图仅在验证后才将数组中的对象排除在数据库中。下面是代码示例

public function store(Request $request)
{
    //
    $request->merge([
        'added_by' => auth('api')->user()->id,
    ]);

    $travel = TravelSummary::create( $this->validateRequest($id = null) );

    event(new TravelRequestCreatedEvent($travel, $action = 'added travel request'));

    return (new TravelSummaryResource($travel))
                ->response()
                ->setStatusCode(Response::HTTP_CREATED);
}

下面是已验证字段的数组

private function validateRequest($id){
    return request()->validate([
        'travel_request_no' => $id ? 'required' : 'required|unique:travel_summaries',
        'purpose' => 'required',
        'total' => 'nullable',
        'cash_advance' => 'nullable',
        'advance_amount' => 'nullable|lte:total',
        'added_by' => 'required'
    ]);
}

只有在验证后才能排除总数吗？

使用

$data = $request->only(['travel_request_no', 'purpose', 'cash_advance', 'advance_amount', 'advance_amount']);

或

验证后，将该数据传递给创建模型。这里有一个例子

$this->validateRequest($id = null);
$data = $request->only(['travel_request_no', 'purpose', 'cash_advance', 'advance_amount', 'advance_amount']);
//or you can use except
//$data = $request->except(['total']);
$travel = TravelSummary::create($data);

---

您可以在验证后取消设置要排除的数据，如下所示：

// The validator will return the validated data as an array
$data = $this->validateRequest($id = null);
// This will remove the key and value from the array.
unset($data['total']);

$travel = TravelSummary::create($data);

// The validator will return the validated data as an array
$data = $this->validateRequest($id = null);
// This will remove the key and value from the array.
unset($data['total']);

$travel = TravelSummary::create($data);
