codeigniter - 嵌套索引文件数组以在 codeigniter 中上传文件

Question

我有以下输入类型文件数组，它是使用来自数据库的 id 作为索引动态生成的，我需要使用图像名称更新字段并上传这些图像。实际上，我正在从调查问卷中制作表格，用户可以在其中选择是否需要文本答案或文件上传。这是我的表单输入如果是文本

<input class="form-control" id="answer" name="addmore[<?php echo $additional->id; ?>][answers]" type="text" value="" required>

别的

<input type="file" id="file" name="addmore[<?php echo $additional->id; ?>][answers]" class="form-control">

这是我对文件输入的回应
