我有使用单文件上传的经验<input type="file">.但是,我无法一次上传多个.
例如,我希望能够一次性选择一系列图像,然后将它们上传到服务器.
如果可能的话,使用单个文件输入控件会很棒.
有谁知道如何做到这一点？谢谢!
我一直在寻找并努力工作3天才能使这个工作,但我不能.我想要做的是使用多文件输入表单,然后上传它们.我不能只使用固定数量的文件上传.我在StackOverflow上尝试了很多解决方案,但我找不到工作的解决方案.
这是我的上传控制器
<?php
class Upload extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->helper(array('form', 'url','html'));
}
function index()
{
$this->load->view('pages/uploadform', array('error' => ' ' ));
}
function do_upload()
{
$config['upload_path'] = './Images/';
$config['allowed_types'] = 'gif|jpg|png';
$this->load->library('upload');
foreach($_FILES['userfile'] as $key => $value)
{
if( ! empty($key['name']))
{
$this->upload->initialize($config);
if ( ! $this->upload->do_upload($key))
{
$error['error'] = $this->upload->display_errors();
$this->load->view('pages/uploadform', $error);
}
else
{
$data[$key] = array('upload_data' => $this->upload->data());
$this->load->view('pages/uploadsuccess', $data[$key]);
}
}
}
}
}
?>
我的上传表格是This.
<html>
<head>
<title>Upload Form</title>
</head>
<body>
<?php …我正在尝试在文件夹中上传多个文件,但它会显示错误"您没有选择要上传的文件".

视图
<div class="form-group col-md-12">
<label for="Attach"><strong>Add Attachment</strong><br></label>
<input type="file" class="btn btn-default btn-file" name="atta[]" id="Attach" multiple="multiple">
</div>
You did not select a file to upload.尽管我选择了要上传的文件，但在尝试上传文件时收到错误消息。我正在使用使用引导程序样式的输入文件。这是问题吗？我按照Codeigniter用户指南中的说明进行文件上传。谁能帮助我，并确定我的代码中的错误？
谢谢
