php+ajax檔案上傳進度條

ajax|上傳

代碼分為以下部分:

demo.php - 上傳過程處理

PLAIN TEXTPHP:

<?php
 
include 'UploadProgressMeter.class.php';
 
$fileWidget = new UploadProgressMeter();
 
if ($fileWidget->uploadComplete()) {
        // 上傳完畢的時候,從iframe發送一個js到主視窗表示一切ok
        echo $fileWidget->finalStatus();
 
        // 處理上傳後的檔案...
 
        exit;
}
?>

demoserver.php - ajax的服務端js,使用Pear:HTML_AJAX,直接調用UploadProgressMeterStatus類

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(); ?>
