我有使用 iframe 的简单 ajax 上传表单。我想要的是，加载消息在 < div id="message"></div> 中显示上传百分比
这是我的javascript
function start_Uploading(){
document.getElementById('message').innerHTML = 'Uploading...';
return true;
}
function stopUpload(success)
{
var result = '';
if (success == 1)
document.getElementById('message').innerHTML = 'Success';
else
document.getElementById('message').innerHTML = 'Failed';
}
这是表格
< div id="message"><br/></div>
< form action="upload.php" method="post" enctype="multipart/form-data" target="upload_target" onsubmit="start_Uploading();" >
File:< input name="myfile" type="file" size="30" />
< input type="submit" name="submitBtn" value="Upload" />
< br/>< iframe id="upload_target" name="upload_target" src="#" style="width:0;height:0;border:0px solid #fff;"></iframe>
</form>
服务器端的upload.php文件是
$destination_path = getcwd().DIRECTORY_SEPARATOR;
$result = 0;
$target_path = $destination_path . basename( $_FILES['myfile']['name']);
if(@move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path))
$result = 1;
sleep(1);
echo "<script language=\"javascript\" type=\"text/javascript\">window.top.window.stopUpload($result);</script>";
最佳答案
两件事:
- 使用Javascript
- 使用 APC
Javascript:
You can use plupload (http://www.plupload.com/)
- pretty good multiple file uploader
Pretty decent JS plugin for uploading files in PHP in two methods,
1. normal upload
2. chunk based uploading.
限制/假设:
1. Flash Plugin - in the browser
2. Session problem - since it's flash, a different session's are created for
each file upload.
APC/PHP
使用 APC - 您可以自己创建进度条。
限制/假设:
1. Install APC on the server - using PECL (pecl install APC)
2. Write a separate code to get the status of upload.
代码:
getprogress.php
<?php
if(isset($_GET['progress_key'])) {
$status = apc_fetch('upload_'.$_GET['progress_key']);
echo $status['current']/$status['total']*100;
}
?>
upload.php
<?php
$id = uniqid("");
?>
<html>
<head><title>Upload Example</title>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
</head>
<body>
<script type="text/javascript">
function getProgress(){
$.get("getprogress.php?progress_key=<?php echo($id)?>",
function(percent) {
document.getElementById("progressinner").style.width = percent+"%";
if (percent < 100){
setTimeout("getProgress()", 100);
}
});
}
function startProgress(){
document.getElementById("progressouter").style.display="block";
setTimeout("getProgress()", 1000);
}
</script>
<iframe id="theframe" name="theframe"
src="fileupload.php?id=<?php echo($id) ?>"
style="border: none; height: 100px; width: 400px;" >
</iframe>
<br/><br/>
<div id="progressouter" style="width: 500px; height: 20px; border: 6px solid red; display:none;">
<div id="progressinner" style="position: relative; height: 20px; background-color: purple; width: 0%; ">
</div>
</div>
</body>
</html>
文件上传.php
<?php
$id = $_GET['id'];
?>
<form enctype="multipart/form-data" id="upload_form"
action="target.php" method="POST">
<input type="hidden" name="APC_UPLOAD_PROGRESS"
id="progress_key" value="<?php echo $id?>"/>
<input type="file" id="test_file" name="test_file"/><br/>
<input onclick="window.parent.startProgress(); return true;"
type="submit" value="Upload!"/>
</form>
