仍然不工作:(我甚至不会在框架中获取POST表单数据。错误？

上传机制，您需要添加一个额外的参数到您的窗体，标识正在上传的文件，是 apc_fetch 的关键。
<？php $ id = uniqid（time（））;？>
关键的 upload。$ id 中的值将包含你需要显示进度条的信息。最简单的方法是用ajax轮询服务器，使用 apc_fetch call you have。这意味着你的上传页面不需要刷新用户所在的当前页面我已经使用了一个 iframe 在过去启动一个我nterval轮询服务器。上传完成后，您可以在相同的iframe中显示完整的信息。
Post Updated: After commentors advice.
Index.php
<?php
$id = uniqid("");
?>
</head>
<body>
<form method="post" action="frame.php" target="upload_iframe" enctype="multipart/form-data">
<label for="file">Filename:</label>
<input type="file" name="file" id="file" />
<input type="hidden" name="APC_UPLOAD_PROGRESS" id="progress_key" value="<?php echo $id; ?>"/>
<br />
<input type="submit" name="submit" value="Submit" />
</form>
<iframe name="upload_iframe" style="width: 400px; height: 100px;">
</iframe>
frame.php
<?php
if(isset($_POST['progress_key'])) {
echo "hey1";
$status = apc_fetch('upload_'.$_POST['progress_key']);
echo $status['current']/$status['total']*100;
}
echo "hey2";
?>
Still doesnt work :(, I dont even get POST form data in frame. Where am i going so wrong?

Whenever you use the APC file upload mechanism, you need to add an additional parameter to your form that identifies the file that's being uploaded, and is the key for your apc_fetch.
<?php $id = uniqid(time()); ?>
<input type="hidden" name="APC_UPLOAD_PROGRESS" id="myUniProgressKey" value="<?php echo $id; ?>"/>
As the file is uploaded the value in the key upload . $id will contain the info you need to display the progress bar. Easiest way to get to is to ajax poll the server, using the apc_fetch call you have. This dictates that your upload page needs to not refresh the current page the user is on. I've used an iframe in the past that kicks off an interval to poll the server. Once the upload is complete, you're able to show a nice complete message in the same iframe.
