php文件上传实现进度条

1.http://www.ugia.cn/?p=54 - 以socket上传文件并显示进度条
09/22更新：发布upuv0.21，增加多语言支持，修改协议由GPL到LGPL。请到 http://sourceforge.net/projects/upu 下载。或者本地下载。

2.php+ajax(本地下载)
http://www.itfly.org/php/jiqiao/a9390.shtml

代码分为以下部分:

demo.php - 上传过程处理

PLAIN TEXTPHP:

<?php

include 'UploadProgressMeter.class.php';

$fileWidget = new UploadProgressMeter();

if ($fileWidget->uploadComplete()) {
// 上传完毕的时候,从iframe发送一个js到主窗口表示一切ok
echo $fileWidget->finalStatus();

// 处理上传后的文件...

exit;
}
?>

demoserver.php - ajax的服务端js,使用Pear:HTML_AJAX,直接调用UploadProgressMeterStatus类

PLAIN TEXTHTML:

<script src="http://www.ooso.net/demoserver.php?client=main,request,httpclient,dispatcher,json,util" type="text/javascript"></script>
<script src="http://www.ooso.net/demoserver.php?stub=UploadProgressMeterStatus" type="text/javascript"></script>
<?php echo $fileWidget->renderIncludeJs(); ?>

进度条的样式表

PLAIN TEXTCSS:

.progressBar {
position: relative;
padding: 2px;
width: 300px;
height: 40px;
font-size: 14px;
}
.progressBar .background {
border: solid 1px black;
width: 270px;
height: 20px;
}
.progressBar .bar {
position: relative;
background-color: blue;
width: 0px;
height: 20px;
}

表单部分

PLAIN TEXTHTML:

<form action="demo.php" method="post" enctype="multipart/form-data">renderFormExtra(); ?>>
<?php echo $fileWidget->renderHidden(); ?></form><form action="demo.php" method="post" enctype="multipart/form-data"><label>Select File: </label>
<div><?php echo $fileWidget->render(); ?>
<?php echo $fileWidget->renderProgressBar(); ?></div>
</form>
