问题:
使用jQuery文件上传完成.txt文件上传后,设置会话变量并将用户重定向到不同的PHP页面。
HTML code(upload.php):
<!-- The fileinput-button span is used to style the file input field as button -->
<span class="btn btn-success fileinput-button">
<i class="glyphicon glyphicon-plus"></i>
<span>Add files...</span>
<!-- The file input field used as target for the file upload widget -->
<input id="fileupload" type="file" name="files[]" multiple>
</span>
<br>
<br>
<!-- The global progress bar -->
<div id="progress" class="progress">
<div class="progress-bar progress-bar-success"></div>
</div>
<!-- The container for the uploaded files -->
<div id="files" class="files"></div>
jQuery代码(upload.php):
<script>
$(function () {
'use strict';
// Server-side upload handler:
var url = 'process.php';
$('#fileupload').fileupload({
url: url,
autoUpload: true,
acceptFileTypes: /(\.|\/)(txt)$/i,
maxFileSize: 5000000, // 5 MB
done: function (e, data) {
$(this).delay(2000, function(){
window.location = "explorer.php";
});
},
progressall: function (e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
$('#progress .progress-bar').css(
'width',
progress + '%'
);
}
}).prop('disabled', !$.support.fileInput)
.parent().addClass($.support.fileInput ? undefined : 'disabled');
});
</script>
PHP上传脚本(process.php):
<?php
session_start();
$folder = 'upload';
if (!empty($_FILES))
{
// Set temporary name
$tmp = $_FILES['files']['tmp_name'];
// Set target path and file name
$target = $folder . '/' . $_FILES['files']['name'];
// Upload file to target folder
$status = move_uploaded_file($tmp, $target);
if ($status)
{
// Set session with txtfile name
$_SESSION['txtfile'] = $_FILES['files']['name'];
}
}
?>
期望的输出:
编辑:已解决。上面的最终代码!

首先......
请注意,您的input
名称为files[]
且属性为multiple
。这意味着你要向服务器发送一个文件数组,以便在php中引用它们,你需要这样的东西:
$_FILES['files']['name'][0]
表示第一个文件。
此外,我发现move_uploaded_file()
喜欢目的地的完整路径,请尝试添加$_SERVER['DOCUMENT_ROOT']
。
要将信息发送回jQuery,您可能希望使用echo json_encode()
,如此...
echo json_encode(array(
'status' => $status,
'message' => 'your message here'
));
在done
函数中,可以像这样访问数据:
done: function(e, data){
console.log(data.status);
console.log(data.message);
}
