In this tutorial we will create a simple 5 star rating system using jQuery, MySQL, PHP and AJAX. We will use jQuery to highlight the star the mouse is over and the preceding stars, AJAX to send the vote to the server, PHP to process the vote and MySQL to store the vote.
The Basic Idea
This
rating system will be able to highlight half-stars, too. Doing this
using only CSS would be difficult, so we will use instead different
background images for each possibility, and on mouse-over we will just
change the background image. In this case appears an another problem: on
changing the background we should wait for the new image to load, so
instead of having a lot of different images we will combine the images
in a single image and on mouse-over we will change the background
position. more...
