This tutorial helps and teaches you how to build a simple but powerful preview and upload multiple files system using Ajax and PHP.

The essence of this tutorial is to teach individuals how they can actually preview files before they are been uploaded.

Our previous scripts on file upload require one external plugin or the other but this one does not rely on any external file upload plugin such as jQuery Form Plugin which has made this application the simplest of all the file upload scripts on Vasplus.

You only need to have the jQuery JavaScript Library which is a necessity for all websites that work with jQuery.

If you have noticed while uploading files with scripts that require the jQuery Form Plugin, you must have seen that your browser tab loads when the files are uploading but this one does not load at all while the files are uploaded.

When you upload a file by browsing for the file or files intended for upload, the files are renamed with a combination of a random string plus the original extension of the file and saved in a folder on your server for later use.

This is one of the best multiple file upload script on Vasplus because the process involve is not much and the system is very easy to implement in any application.

The system supports all modern web browsers and the scripts are written in a way that any one with a basic HTML, JavaSceipt and PHP knowledge can easily understand and customize with programming code comments to ease usability.

To install the system on your server after you must have downloaded the zipped folder containing the required files, extract the zipped folder to your server and locate the index.php file of the script to start using it. No special configuration is required.

To see the system in action, please click on the Live Demo button below and download the script if you like what you see.
