Question

我在CodeIgniter中进行图像多重上传，这是我的代码。这段代码很有用，但我想让它变得更简单，而且我一直在尝试使用＆＃39; foreach＆＃39;，并且收到了很多错误。请帮助，谢谢。

如果您使用

，我不明白为什么会出现错误

foreach(array('userfile', 'userfile2', 'userfile3') as $filename) {
    if (!empty($_FILES[$filename]['name'])) {
        ...
        if ( ! $this->upload->do_upload($filename)) {
        ...
    } 
}

您能否提供有关系统显示的错误的更多信息？
