Question

我正在创建一个包含最多20个图像文件的库存表单。将图像上传到服务器时，我需要更改名称并将其插入数据库，以便它可以在网站轮播上使用。名称更改正常以及上载到servers文件夹。我似乎遇到的问题是，如果我选择所有的图像它工作得很好，但如果我选择较少，（即1,2,3,4等）然后它会中断。我可能看起来很明显了。任何帮助 - 任何想法??

这就是我的所在;

有人可以帮忙吗？

请在for循环中添加一张支票：

foreach($files['name'] as $position => $file_name) {
    $uploaded[$position] = '';
    if(!empty($file_name)) {
        //your code here
    }
}
