Php codeigniter文件上载失败，无错误

下面是通过codeigniter上传多个文件的代码，但这不起作用。它总是抛出错误“未选择文件”

HTML

}

这就产生了这样的输出

请建议如何上载这些文件。

我建议首先转到。现在关于您的问题，因为我知道您没有将文件字段的名称传递给

do_upload（）

方法。下面是对代码的修改

foreach($_FILES['userfile']['name'][$i+1] as $file){
        //your logic

        if ( ! $this->upload->do_upload('images')){    
          $error = array('error' => $this->upload->display_errors());
        exit; }
        else
        redirect('dashboard/failure');
    }

请先尝试打印（$error），然后退出要上载文件的文件夹权限。打印（$error）表示数组（[error]=>您没有选择要上载的文件。）

function upload(){
  print_r($_FILES);exit;
