php ajax文件上传进度条

---

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>

其它类似项目:
