Php 使用Codeigniter进行多个图像上载，只将一个文件路径保存到MySQL数据库

现在我正在构建一个应用程序。我已经建立了一个表单，将上传多个图像到数据库。这是我的简单代码

查看

<?php echo form_open_multipart('admin/product/post'); ?>
<table class="table table-stripped">
    <tbody>
        <tr>
            <td>Code</td>
            <td>
                <?php echo form_input(array('class'=>'form-control','name'=>'kodeproduk')); ?>                                  
            </td>
        </tr>
        <tr>
            <td>Display</td>
            <td>
                <input class="form-control" type="file" name="userfile[]" id="multiple" multiple="" />    
            </td>
        </tr>
        <tr>
            <td>Description</td>
            <td>
                <div class="textarea textarea-editor">
                    <textarea name="ket" cols="50" rows="5" class="form-control"></textarea>
                </div>                                  
            </td>
        </tr>
        <tr>
            <td colspan="2">
                <button type="submit" class="btn btn-primary btn-outline btn-block pull-right"><span>Save</span></button>
            </td>
        </tr>
    </tbody>
</table>
<?php echo form_close(); ?>

我在发布时遇到了一个问题，所有的图像文件都上传到服务器上的目录中，但是只有一个图像作为一行存储到MySQL表中。那么如何修复我的代码呢？感谢您的帮助，一些小的改动可能会有所帮助

好的，一些小改动可能会有所帮助
