PECL Uploadprogress不会给我上传进度

Question

I am trying to implement a very basic AJAX upload progress bar using the PECL uploadprogress extension. 我正在尝试使用PECL uploadprogress扩展实现非常基本的AJAX上传进度栏。 I have found this sample code which works across all browsers: http://svn.php.net/viewvc/pecl/uploadprogress/trunk/examples/ . 我发现此示例代码可在所有浏览器上使用： http : //svn.php.net/viewvc/pecl/uploadprogress/trunk/examples/ 。 It uses iframes to write the updates to. 它使用iframe将更新写入。 I would like to get the updates and do some jquery to build a progress bar. 我想获取更新并执行一些jquery来构建进度栏。 Here is my code (I know I did not write in code to account for when the upload ends) client.php: 这是我的代码（我知道我没有写代码来说明上传结束的时间）client.php：

<?php
$id = md5(microtime() . rand());
?>

<!DOCTYPE html>
<html>

<script type="text/javascript" src="jquery-1.7.2.min.js"></script>
<script type="text/javascript">
        function getProgress(){
            $.get("progress.php", {"ID":'<?php echo $id ?>'}, function(data){
                console.log(data);
            });
            window.setTimeout(getProgress(), 5000);
        }
</script>

<body>
    <form onsubmit="getProgress()" target="_self" enctype="multipart/form-data" method="post">
        <input type="hidden" name="UPLOAD_IDENTIFIER" value="<?php echo $id;?>" />
        <label>Select File:</label>
        <input type="file" name="file" />
        <br/>
        <label>Select File:</label>
        <input type="file" name="file2" />
        <br/>
        <label>Upload File:</label>
        <input id="submitButton" type="submit" value="Upload File" />
    </form>
</body>
</html>

And progress.php: 和progress.php：

<?php
if (function_exists("uploadprogress_get_info")) {

    $info = uploadprogress_get_info($_GET['ID']);
} else {
    $info = false;
}

$progress = ($info['bytes_uploaded']/$info['bytes_total'])*100;

echo $progress;

I error out and all that prints is 0's. 我错了，所有打印的都是0。 Any ideas? 有任何想法吗？

Try replacing 尝试更换

$progress = ($info['bytes_uploaded']/$info['bytes_total'])*100;

with 与

$progress = ($info['bytes_uploaded']*100)/$info['bytes_total'];

Both $info['bytes_uploaded'] and $info['bytes_total'] are integers, so division is not a float but is rounded down to a integer. $info['bytes_uploaded']和$info['bytes_total']都是整数，因此除法不是浮点数，而是四舍五入为整数。
