我正忙着尝试在jQuery文件上传插件中提交其他表单数据。这里描述了https://github.com/blueimp/jQuery-File-Upload/wiki/How-to-submit-additional-Form-Data，但它没有详细介绍如何在UploadHandler.php中检索和使用该数据。以下是我的内容：
index.php（表格）：
<form id="fileupload" action="<?php echo $this->config->item('base_url'); ?>/cool_upload/server/php/" method="POST" enctype="multipart/form-data">
<input type="hidden" id="userID" value="<?php echo $this->session->userdata('id'); ?>">
<!-- The fileupload-buttonbar contains buttons to add/delete files and start/cancel the upload -->
<div class="row fileupload-buttonbar">
<div class="span7">
<!-- The fileinput-button span is used to style the file input field as button -->
<span class="btn btn-success fileinput-button">
<i class="icon-plus icon-white"></i>
<span>Add files...</span>
<!-- REMOVED MULTIPLE FROM HERE TO ONLY ALLOW ONE FILE AT A TIME!!!! -->
<input type="file" name="files[]">
</span>
<button type="submit" class="btn btn-primary start">
<i class="icon-upload icon-white"></i>
<span>Start upload</span>
</button>
<button type="reset" class="btn btn-warning cancel">
<i class="icon-ban-circle icon-white"></i>
<span>Cancel upload</span>
</button>
<button type="button" class="btn btn-danger delete">
<i class="icon-trash icon-white"></i>
<span>Delete</span>
</button>
<input type="checkbox" class="toggle">
</div>
</div>
<!-- The global progress information -->
<div class="span5 fileupload-progress fade">
<!-- The global progress bar -->
<div class="progress progress-success progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100">

</div>
<!-- The extended global progress information -->
<div class="progress-extended"> </div>
</div>
<!-- The loading indicator is shown during file processing -->
<div class="fileupload-loading"></div>
<br>
<!-- The table listing the files available for upload/download -->
<table role="presentation" class="table table-striped"><tbody class="files" data-toggle="modal-gallery" data-target="#modal-gallery"></tbody></table>
</form>
<br>
<!-- The template to display files available for upload -->
<script id="template-upload" type="text/x-tmpl">
<tr class="template-upload fade">

{

</td>
<td colspan="2" class="name" width="20"><span>{%=file.name%}</span></td>
<td colspan="2" class="size"><span>{%=o.formatFileSize(file.size)%}</span></td>
{% if (file.error) { %}
<td class="error" colspan="2"><span class="label label-important">Error</span> {%=file.error%}</td>
{% } else if (o.files.valid && !i) { %}
<td>
<div class="progress progress-success progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="0"><div class="bar" style="width:0%;"></div></div>

<td class="start">{% if (!o.options.autoUpload) { %}

</script>
main.js：
$('#fileupload').bind('fileuploadsubmit', function (e, data) {
data.formData = $('form').serializeArray();
});
UploadHandler.php：
- 这是我对帖子功能的编辑：
public function post($print_response = true) {
if (isset($_REQUEST['_method']) && $_REQUEST['_method'] === 'DELETE') {
return $this->delete($print_response);
}
$upload = isset($_FILES[$this->options['param_name']]) ?
$_FILES[$this->options['param_name']] : null;
// Parse the Content-Disposition header, if available:
$file_name = isset($_SERVER['HTTP_CONTENT_DISPOSITION']) ?
rawurldecode(preg_replace(
'/(^[^"]+")|("$)/',
'',
$_SERVER['HTTP_CONTENT_DISPOSITION']
)) : null;
// Parse the Content-Range header, which has the following form:
// Content-Range: bytes 0-524287/2000000
$content_range = isset($_SERVER['HTTP_CONTENT_RANGE']) ?
preg_split('/[^0-9]+/', $_SERVER['HTTP_CONTENT_RANGE']) : null;
$size = $content_range ? $content_range[3] : null;
$files = array();
// IF THERE ARE MULTIPLE FILES
if ($upload && is_array($upload['tmp_name'])) {
// param_name is an array identifier like "files[]",
// $_FILES is a multi-dimensional array:
foreach ($upload['tmp_name'] as $index => $value) {
$files[] = $this->handle_file_upload(
$upload['tmp_name'][$index],
$file_name ? $file_name : $upload['name'][$index],
$size ? $size : $upload['size'][$index],
$upload['type'][$index],
$upload['error'][$index],
$index,
$content_range,
isset($_REQUEST['userID']) ? $_REQUEST['userID'] : null,
null
);
}
} else {
// param_name is a single object identifier like "file",
// $_FILES is a one-dimensional array:
$files[] = $this->handle_file_upload(
isset($upload['tmp_name']) ? $upload['tmp_name'] : null,
$file_name ? $file_name : (isset($upload['name']) ?
$upload['name'] : null),
$size ? $size : (isset($upload['size']) ?
$upload['size'] : $_SERVER['CONTENT_LENGTH']),
isset($upload['type']) ?
$upload['type'] : $_SERVER['CONTENT_TYPE'],
isset($upload['error']) ? $upload['error'] : null,
null,
$content_range,
isset($_REQUEST['userID']) ? $_REQUEST['userID'] : null,
null
);
}
return $this->generate_response(array('files' => $files), $print_response);
}
-I将参数添加到handle_file_upload
protected function handle_file_upload($uploaded_file, $name, $size, $type, $error,
$index = null, $content_range = null, $userID) {
当我尝试使用$ userID时，我什么都没得到，因为它是空的。如何使用表单中的userID？同样在index.php中，在模板显示区域中如何使用这些添加的输入呢？例如，我有一个输入changeFilerName和一个选择来选择类别。我已经阅读了文档，但我仍然不确定如何将内容传递给UploadHandler。

首先，请确保通过查看页面来源，在隐藏表单字段中填充$ userID。隐藏的表单字段需要这样的名称：
<input name="userID" id="userID" ....
在PHP端，该输入的值将在$ _POST数组
中可用$_POST['userid']
您还应该在浏览器附带的开发人员工具控制台或Firebug等工具中观察Ajax请求的请求/响应。

尝试使用此插件上传大量文件。 并且它自动支持检测浏览器是否支持html5或flash或java
