File Upload Progress Bar with Jquery and PHP.

We received many tutorial requests from 9lessons readers that asked how to create file upload progress bar with PHP and Jquery. In this post Arun Kumar Sekar had developed few lines of code using PHP APC library, it is very simple getting the server file upload process every few second and increasing the bar color using jquery css property. Just take a look at this demo.

File Upload Progress Bar

Download Script     Live Demo

Arun Kumar Shekar

Chennai, INDIA

To run this script you have to install PHP apc library extension or for PHP 5.4 not required, just follow the steps to enable the extension. For web page design we implemented with bootstrap CSS library for any information check my previous post Bootstrap Tutorial

Windows APC Installation
Follow this link Click Here
In php.ini include apc.rfc1867 = on

Linuk APC Installation
Follow this Link Click Here
In php.ini include apc.rfc1867 = on
php.ini located in /etc/php.ini

Contains PHP code it identifies file upload status from server process.
// For PHP 5.4 users
$progress_key = ini_get("session.upload_progress.prefix")."uploadImage"; // uploadImage is a Form name
$current = $_SESSION[$progress_key]["bytes_processed"];
$total = $_SESSION[$progress_key]["content_length"];
echo $current < $total ? ceil($current / $total * 100) : 100;
// For PHP 5.2+ php_apc.dll or php_apc.so holder
if(isset($_GET['progress_key']) and !empty($_GET['progress_key'])){
$status = apc_fetch('upload_'.$_GET['progress_key']);
    echo $status['current']/$status['total']*100;

General form file upload with PHP. You have to include validation rules, please check my previous post for help.
$uiq = uniqid();
$image_folder = "uploads/";
$uploaded = false;

if($_FILES['userImage']['error'] == 0 ){
$up = move_uploaded_file($_FILES['userImage']['tmp_name'], $image_folder.$_FILES['userImage']['name']);
$uploaded = true;
<form name="uploadImage" id="uploadImage" enctype="multipart/form-data" action="index.php?progress=<?php echo($uiq)?>" method="post" class="well">
<label>Upload File</label>
<input type="file" name="userImage" id="userImage" />
<span class="badge badge-info" style="display:none;">0%</span>
<input type="submit" class="btn btn-success" name="upload_image" id="upload_image" value="UPLOAD FILE" />
<div class="progress" style="display:none;"><div class="bar" style="width:0%;"></div></div>

JavaScript File
Contains simple javascript implemented with Jquery properties getting server file process every few seconds.
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.js"></script>
<script type="application/javascript">
var randIDS = '<?php echo $uiq?>';
// Add Hidden Field
var hidden = $("<input>");

var p = $(this);

// creating iframe
if($("#tmpForm").length == 0){
var frame = $("<iframe>");
// Start file upload
$.get("get_progress.php", {progress_key:randIDS, rand:Math.random()},
var uploaded = parseInt(data);
if(uploaded == 100){
$(".progress, .badge").hide();
else if(uploaded < 100)
$(".progress, .badge").show();
var cWidth = $(".bar").css('width', uploaded+"%");
if(uploaded < 100)
var loader = setInterval(loadLoader,2000);

var loadLoader = function(){
$.get("get_progress.php", {progress_key:randIDS, rand:Math.random()}, function(data)
var uploaded = parseInt(data);
if(uploaded == 100){
$(".progress, .badge").hide();
else if(uploaded < 100)
$(".progress, .badge").show();
var cWidth = $(".bar").css('width', uploaded+"%");

Really Nice Script Dude

Syaiful said...

good job

How do i check file upload size?

Anonymous said...

For those of you saying it goes from 0% to successful, upload a larger image. Small images takes to fast to upload for the script to update the progress.

To developer. You should maybe check file size and set update time according to that? For small files, the status bar never gets time to update.

jacob said...

may i know from where you all guys see the upload bar??

i have uploaded large as well as small image but nothing happened also checking i different browsers meas firefox as well but :(

why the demo not seen completely??

one more thing want to say Please correct the Linux APC Installation instead of Linuk APC Installation

prince said...

Ricardoo said...

Man, great post!...
But i'm so confused and tired of trying to make it work properly.
My progress bar is not reaching 100%.
do you know any resolution for that?


web degin said...

nice but when not upload in this progress bar no information are come in this bar

Anonymous said...

progress bar showing when we click on upload button.... please tell me how we show same progress bar only after browse or without clicking on upload button.... like attachment in gmail

Jacques Mulder said...

For those who do not see the progress bar at first.
in the index.php file the javascript must be in between the php and the html. The Javascript has an php echo $uiq and must be defined by the php first.

Also make sure you read and install the boostrap css also. After that it worked 100%

Anonymous said...

Oh man, perfect!!!!!

Thanksss a lot from Brazil!

Anonymous said...

where to put the javascript file

Anonymous said...


I tested all of your suggestions and I always get the same problem : "current" and "total" values are still to 0. I am wondering where it comes from and asking myself if APC is really working with my file.

Any suggestion ?

I really tried a LOT of things...

Anonymous said...

Just an FYI.. even though I am subscribed I was not able to download the files when I entered my email address. I am a regular visitor to this site but not being able to download drives me away from the site. Eventually I looked at other sites for the same code.

Mustafa said...

Very nice work, congratulations,

Tyguy said...

For those of you still not seeing the progress bar, try these things:

Make sure to include bootstrap.css
Make sure APC is installed
Make sure to add these to php.ini:
apc.rfc1867 = on

That last one, rfc1867 is required for progress upload statuses to work.

The Progrees bar is not runing 100%. still is showing empty. bascially the hosting is Linux server, related DLL files are configured. still also not getting result. colud u plz help me out

Rakesh said...

Please help...
apc_fetch returns data once file completely up-loaded.
while file getting up-loaded it always return false so I always see 0%.

WebGraf said...
