Ajax Select and Upload Multiple Images with Jquery

Very few days back I had posted an article about Multiple ajax image upload without refreshing the page using jquery and PHP. In this post I have updated few lines of code that allows to user can select and upload multiple images in single shot, thanks to Lakshmi Maddukuri for sending me a useful piece of code. Just take a quick look this live demo.

Multiple Ajax Image Upload without Refreshing Page using Jquery and PHP.

Download Script     Live Demo

Sample database design for Users.

Contains user details username, password, email, profile_image and profile_image_small etc.
CREATE TABLE `users` (
`username` varchar(255) UNIQUE KEY,
`password` varchar(100),
`email` varchar(255) UNIQUE KEY

User Uploads
Contains user upload details upload_id, image_name, user_id_fk(foreign key) and timestamp etc.
CREATE TABLE  `user_uploads` (
`upload_id` int(11) AUTO_INCREMENT PRIMARY KEY,
`image_name` text,
`user_id_fk` int(11),
`created` int(11)

Javascript Code
$("#photoimg").live('change',function(){})- photoimg is the ID name of INPUT FILE tag and $('#imageform').ajaxForm() - imageform is the ID name of FORM. While changing INPUT it calls FORM submit without refreshing page using ajaxForm() method. Uploaded images will prepend inside #preview tag.
<script type="text/javascript" src="http://ajax.googleapis.com/
<script type="text/javascript" src="jquery.wallform.js"></script>
<script type="text/javascript">

$('#photoimg').live('change', function()
var A=$("#imageloadstatus");
var B=$("#imageloadbutton");

$("#imageform").ajaxForm({target: '#preview',
} }).submit();

Here hiding and showing #imageloadstatus and #imageloadbutton based on form upload submit status.

Contains simple PHP and HTML code. Here $session_id=1 means user id session value.
$session_id='1'; // User login session value
<div id='preview'>
<form id="imageform" method="post" enctype="multipart/form-data" action='ajaxImageUpload.php' style="clear:both">
Upload image: 
<div id='imageloadstatus' style='display:none'><img src="loader.gif" alt="Uploading...."/></div>
<div id='imageloadbutton'>
<input type="file" name="photos[]" id="photoimg" multiple="true" />

Contains PHP code. This script helps you to upload images into uploads folder and it will  rename image file into timestamp+session_id.extention format to avoid duplicates. This system will store image files into user_uploads with user session id tables
$session_id='1'; //$session id
define ("MAX_SIZE","2000"); // 2MB MAX file size
function getExtension($str)
$i = strrpos($str,".");
if (!$i) { return ""; }
$l = strlen($str) - $i;
$ext = substr($str,$i+1,$l);
return $ext;
// Valid image formats 
$valid_formats = array("jpg", "png", "gif", "bmp","jpeg");
if(isset($_POST) and $_SERVER['REQUEST_METHOD'] == "POST")
$uploaddir = "uploads/"; //Image upload directory
foreach ($_FILES['photos']['name'] as $name => $value)
$filename = stripslashes($_FILES['photos']['name'][$name]);
//Convert extension into a lower case format
$ext = getExtension($filename);
$ext = strtolower($ext);
//File extension check
//File size check
if ($size < (MAX_SIZE*1024))
echo "<img src='".$uploaddir.$image_name."' class='imgList'>";
//Moving file to uploads folder
if (move_uploaded_file($_FILES['photos']['tmp_name'][$name], $newname))
//Insert upload image files names into user_uploads table
mysql_query("INSERT INTO user_uploads(image_name,user_id_fk,created) VALUES('$image_name','$session_id','$time')");
echo '<span class="imgList">You have exceeded the size limit! so moving unsuccessful! </span>'; }

echo '<span class="imgList">You have exceeded the size limit!</span>';


echo '<span class="imgList">Unknown extension!</span>';

} //foreach end


Database configuration file, just modify database credentials.
$mysql_hostname = "localhost";
$mysql_user = "username";
$mysql_password = "password";
$mysql_database = "database";
$prefix = "";
$bd = mysql_connect($mysql_hostname, $mysql_user, $mysql_password) or die("Opps some thing went wrong");
mysql_select_db($mysql_database, $bd) or die("Opps some thing went wrong");

Style for image blocks.
border:1px solid #dedede;

Thanks for sharing, this is a good example for Ajax upload.

Dropzone.js is another good script for multiple file upload.
