如何使用 laravel 插入和上传多个文件？

Question

<h4 class="card-title">Add Product</h4>
<form class="forms-sample" action="{{route('AddNewProduct')}}" method="post" enctype="multipart/form-data">
    {{csrf_field()}}
    <div id="dynamicTable">
        <div class="row">
            <div class="col-md-4">
                <div class="form">
                    <label class="bmd-label-floating">Product Image</label>
                    <input type="file" name="product_image[]" class="form-control">
                </div>
            </div>
            <div class="col-md-2">
                <div class="form">
                    <button type="button" name="add" id="add" class="btn btn-success"><i class="fa fa-plus"></i></button>
                </div>
            </div>
        </div>
    </div>
    <button type="submit" class="btn btn-primary pull-center">Submit</button>
</form>

<script type="text/javascript">
    var i = 0;
    $("#add").click(function(){
        ++i;
        $("#dynamicTable").append('<div class="row"><div class="col-md-4"><div class="form"><input type="file" name="product_image[]" class="form-control"></div></div><div class="col-md-2"><div class="form"><button type="button" class="btn btn-danger remove-tr"><i class="fa fa-minus"></i></button></div></div></div>');
    });
    $(document).on('click', '.remove-tr', function(){  
        $(this).closest(".row").remove();
    });  
</script>

function：

public function AddNewProduct(Request $request)
{
    $date=date('d-m-Y');
    $this->validate(
        $request, [
                    'product_image' => 'required',
                    'product_image.*' => 'mimes:jpeg,png,jpg',
                ]
        );

    if($request->hasfile('product_image'))
    {
        foreach($request->file('product_image') as $file)
        {
            $fileName = $file->getClientOriginalName();
            $fileName = str_replace(" ", "-", $fileName);
            $file->move('images/product/'.$date.'/', $fileName);
            $product_image[] = 'images/product/'.$date.'/'.$fileName; 
        }
    }

    echo "<pre>";
    print_r($product_image);
}

在上面的代码中，我通过单击添加按钮动态添加多个文件，现在可以正常工作当我单击提交按钮并尝试打印多个图像时会发生什么，然后只显示 1 个文件我现在不知道为什么？ 那么，如何使用 laravel 上传多个文件并插入数据库？ 请帮我。

谢谢你

您可以使用以下代码：

public function AddNewProduct(Request $request)
{
    $date=date('d-m-Y');

    $this->validate(

        $request, [
                    'product_image' => 'required',
                    'product_image.*' => 'mimes:jpeg,png,jpg',
                ]
        );

    $temImageArray = [];

    $product_image = [];

    if($request->hasfile('product_image'))
    {
        foreach($request->file('product_image') as $file)
        {
            $fileName = $file->getClientOriginalName();

            $fileName = str_replace(" ", "-", $fileName);

            $file->move('images/product/'.$date.'/', $fileName);

            $product_image[] = 'images/product/'.$date.'/'.$fileName; 

            array_push( $temImageArray ,  $product_image);
        }
    }

    echo "<pre>";
    print_r($temImageArray);
}
