如何在单独的行中将数组索引数据保存到数据库中？

Question

我有一个属于产品表的特色表（外键 = product_id），现在我想将一些产品 id 保存到我的特色表中，它给了我一个数组结果，但我无法将其保存到数据库中强>

这是我的控制器 -->

  public function featuredProduct(Request $request)
   {
       if($request->isMethod('POST')){
         $product_id=$request->all();
         foreach ($product_id as $product) {
            $products[]=$product;
         }
         //dd($products);
       Featured::create($products);
       }
       return view('admin.products.featured');
   }

<form action="{{ route('featuredProduct') }}" method="POST" multiple>
  <table id="datatable-responsive" class="table table-striped table-bordered dt-responsive nowrap verticle_middle">
    <thead>
      <tr>
        <th>Product</th>
        <th>Category</th>
        <th>Image</th>
        <th>Status</th>
      </tr>
    </thead>
    <tbody>
    @foreach ($products as $product)
      <tr>
        <td>
          <input id="{{ $product->id }}" value="{{ $product->id }}" type="checkbox" name="product[]">
          <label for=id={{ $product->id }}>{{ $product->product_name }}</label>
        </td>
        <td> {{ $product->category['cat_name'] }} </td>
        <td> <img src="{{asset($product->pro_img) }}" alt="" width="40"> </td>
        <td class="center">
        @if ($product->status === 1)
            <span class="btn btn-primary btn-xs">Published</span>
        @else
            <span class="btn btn-warning btn-xs">Unpublish</span>
        @endif
        </td>
        </tr>
          @endforeach
       </tbody>
    </table>
    <div class="modal-footer">
      <button type="button"class="btn btn-default waves-effect" data-dismiss="modal">Close</button>
      <button type="submit" class="btn btn-primary waves-effect waves-light">Submit</button>
    </div>
</form>

您可以在 for 循环中创建每个功能。

public function featuredProduct(Request $request)
{
    if($request->isMethod('POST')) {
        foreach($request->all() as $productId) {
            Featured::create([
                'product_id' => $productId,
                ... other data fields.
            ]);
        }
    }
}

或者，如果您想一次保存所有功能。

public function featuredProduct(Request $request)
{
    if($request->isMethod('POST')) {

        $featureds = [];

        foreach($request->all() as $productId) {
            $featureds[] = [
                'product_id' => $productId,
                ... other data fields.
            ]
        }

        DB::table('featureds')->insert($featureds);
    }
}
