File Upload Progress Bar In Php Using Jquery

I am using

Malsup's jQuery File Upload Progress Bar for visualizing progress bar while uploading files to server. I am using it now at present. I have got the following doubts in this plugin:

 

1) File uploads even if the progress bar has not achieved 100%

 

2) If the File size is more than 10 MB, it loads upto 100% in the progress bar and echoes Upload failed! message.

 

Here is the code :

 

 


<!doctype html>
<head>
<title>Uploads</title>
<style>
body { padding: 30px }
form { display: block; margin: 20px auto; background: #eee; border-radius: 10px; padding: 15px }[/left]

[/font][/color]


.progress { position:relative; width:400px; border: 1px solid #ddd; padding: 1px; border-radius: 3px; }
.bar { background-color: #B4F5B4; width:0%; height:20px; border-radius: 3px; }
.percent { position:absolute; display:inline-block; top:3px; left:48%; }
</style>
</head>
<body>
<h1>File Upload</h1>
<form action="file.php" method="post" enctype="multipart/form-data">
<input type="file" name="myfile[]" multiple><br>
<input type="submit" value="Upload File to Server">
</form>


<div class="progress">
<div class="bar"></div >
<div class="percent">0%</div >
</div>


<div id="status"></div>


<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.js"></script>
<script src="http://malsup.github.com/jquery.form.js"></script>
<script>
(function() {


var bar = $('.bar');
var percent = $('.percent');
var status = $('#status');


$('form').ajaxForm({
beforeSend: function() {
status.empty();
var percentVal = '0%';
bar.width(percentVal)
percent.html(percentVal);
},
uploadProgress: function(event, position, total, percentComplete) {
var percentVal = percentComplete + '%';
bar.width(percentVal)
percent.html(percentVal);
//console.log(percentVal, position, total);
},
complete: function(xhr) {
status.html(xhr.responseText);
}
});


})();
</script>
<script src="http://www.google-analytics.com/urchin.js" type="text/javascript"></script>
<script type="text/javascript">
_uacct = "UA-850242-2";
urchinTracker();
</script>


The form action -> file.php code :

 

<?php
$upload_directory = "../users/Files/";
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $upload_directory . $_FILES['userfile']['name'])) {
print "<br><br>";
print "<font color='black'>File Uploaded Successfully</font>";
print "<br><br>";
print "<font color='black'>Uploaded File is {$_FILES['userfile']['name']} and its size is {$_FILES['userfile']['size']} bytes </font>";
} else {
print "Upload failed!";
}
?>

 

 

 

My server settings for File Uploads:

post_max_size 1050M 1050M

 

upload_max_filesize 1050M 1050M

 

upload_tmp_dir /tmp /tmp

Settings in php.ini :

max_execution_time = 30 ; Maximum execution time of each script, in seconds

 

max_input_time = -1

 

memory_limit = 2000M ; Maximum amount of memory a script may consume (8MB)

I don't see anything specifically wrong, however:

  • the file upload depends on xhr2 support in the browsers, and IE does not support xhr2. They author claims to provide fallback to iframe, but this is something you'd obviously have to test extensively if IE support is important to you.
  • While your settings look ok, you should check phpinfo to determine whether those settings are actually reflected in your running webserver
  • the upload not reaching 100% seems to be a design flaw, in that that the upload is completed and the request completed before it updates the client ui to display it. I don't know that you can fix that, or that it's a problem worth fixing.
