In this post I will give the step by step explanation of how we can add Voting Functionality to a website. At the end of this article we will have a working sample voting application. The source code for the sample voting application can be downloaded from here.
We will be using PHP, MySQL, jQuery, HTML, CSS, AJAX to implement this.
To setup this functionality we will have to first setup database, then a front-end and also a page which would actually record and retrieve the votes.
