请帮助我亲爱的，我想尝试启用其他标题和其他上传文件的多输入.是不是我做的控制器有问题，所以它循环其他标题和多个文件，只有一个上传到数据库？

这是我的代码视图

<!-- Modal -->
                        <div class="form-row">
                            <div class="form-group col-md-12">
                                <label for="otitle">Other</label>
                                <div class="form-row add-container">
                                    <div class="col-6">

这是我代码的Controller
