Question

我有多个输入，我可以通过单击按钮（+）在任意位置克隆div来添加更多内容。

我需要它，以便在保存表单时数据为空，并使用所有div和输入将其重定向回。例如：添加五个输入，然后单击“提交并重定向”时，我需要显示此输入（五个输入）。

这是我的示例代码：

<form class="m-form m-form--fit m-form--label-align-right" id="m_form_1" method="post">
    <div class="m-portlet__body">
        @if(is_array(old('name')) && count(old('name')) > 0)
            <div id="countriesContainer">
                @foreach(old('name') as $key => $item)
                    <div class="form-group m-form__group row countries">
                        <label class="col-form-label col-lg-2">{{ trans('general.language') }}</label>
                        <div class="col-2">
                            <select class="form-control m-bootstrap-select m_selectpicker" data-live-search="true" name="language[]">
                                <option value="">{{ trans('general.select_item') }}</option>
                                @foreach($language as $row)
                                    <option value="{{ $row->locale }}" {{ old('language')[$item] == $row->locale ? 'selected' : '' }}>{{ $row->name }}</option>
                                @endforeach
                            </select>
                        </div>
                        <div class="col-lg-6">
                            <input type='text' class="form-control m-input lang" name="name" value="{{ old('name')[$item] }}" placeholder="{{ trans('countries.name') }}"/>
                        </div>
                        <div class="col-2">
                            <a href="javascript:;" class="btn btn-brand m-btn m-btn--custom add">
                                <i class="fa fa-plus"></i>
                            </a>
                            <a href="javascript:;" class="btn btn-danger m-btn m-btn--custom remove">
                                <i class="fa fa-minus"></i>
                            </a>
                        </div>
                    </div>
                @endforeach
            </div>
        @else
            <div id="countriesContainer">
                <div class="form-group m-form__group row countries">
                    <label class="col-form-label col-lg-2">{{ trans('general.language') }}</label>
                    <div class="col-2">
                        <select class="form-control m-bootstrap-select m_selectpicker" data-live-search="true" name="language">
                            <option value="">{{ trans('general.select_item') }}</option>
                            @foreach($language as $row)
                                <option value="{{ $row->locale }}" {{ old('language') == $row->locale ? 'selected' : '' }}>{{ $row->name }}</option>
                            @endforeach
                        </select>
                    </div>
                    <div class="col-lg-6">
                        <input type='text' class="form-control m-input lang" name="name" placeholder="{{ trans('countries.name') }}"/>
                    </div>
                    <div class="col-2">
                        <a href="javascript:;" class="btn btn-brand m-btn m-btn--custom add">
                            <i class="fa fa-plus"></i>
                        </a>
                        <a href="javascript:;" class="btn btn-danger m-btn m-btn--custom remove">
                            <i class="fa fa-minus"></i>
                        </a>
                    </div>
                </div>
            </div>
        @endif
    </div>
</form>

这是我的控制器代码：

$language = $request->get('language');
$name = $request->get('name');
$status = (int)$request->get('status');
$validator = Validator::make($request->all(), [
    "name.*"  => "required",
]);

Answer 1

<input name="name" ...应该是<input name="name[]" ...，如果存在多个具有相同名称的输入字段，则它应该是一个数组。

要获得旧值，您需要loop index。不是$item

所以应该是

<input name="name[]" value="{{ old('name')[$loop->index] }}" ...
