Laravel 文件上传问题

Question

我有一个带有文件上传输入的简单表单，它不会转储文件输入值。

这是我的表单代码：

<!-- Modal -->
        <div class="modal fade" id="app-form" tabindex="-1" role="dialog" aria-labelledby="app-form-label">
            <div class="modal-dialog" role="document">
                <div class="modal-content">
                    <div class="modal-header">
                        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span
                                    aria-hidden="true">&times;</span></button>
                        <h4 class="modal-title" id="app-form-label">Ședință foto boudoir!</h4>
                    </div>

                    {!! Form::open(['url'=>'','method'=>'POST', 'files'=>true, 'id' => 'model-form']) !!}
                    <div class="modal-body">

                        {!! Form::file('image') !!}
                    </div>
                    <div class="modal-footer">
                        <button type="submit" class="btn btn-warning card-2">Trimite Datele</button>
                    </div>
                    {!! Form::close() !!}
                </div>
            </div>
        </div>
        <!-- /End Modal -->

我用 ajax 用这段代码来发帖：

<script>
    (function () {
        $('#model-form').submit(function (e) {
            e.preventDefault();
            $.ajax({
                type: 'POST',
                url: 'store',
                headers: {
                    'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                },
                data: new FormData(this),
                contentType: false,
                cache: false,
                processData:false,
                success: function (response) {
                    console.log($('#image').val());
                }
            });
        });
    })();
</script>

现在不要问我为什么要在 ajax 中设置 csrf-token 标头，这是另一个问题，但现在的问题是我在提交表单后执行了 $_POST 和 $_FILES 转储，我拥有所有除图像文件上传数据外的表单值。 我正在用这个把头发拉出来，所以请帮帮我！

当您尝试以如下形式发送文件数据时，您应该使用enctype=multipart/form-data：

<form action="" method="POST" enctype="multipart/form-data">
</form>

您可以像这样在控制器中使用 laravel 的 dd() 方法转储输入：

dd(request()->all());

希望这会有所帮助！
