One great element of user interface and improving the customer’s experience on your site is providing them with helpful feedback during their experience. We most often see examples of this in form validation, whether it’s a sign up form with email validation or during the checkout process on an ecommerce site – it’s nice to let the user know that what they did was correct or quickly let them know they need to make changes so their time is not wasted and their patience are not tested. Here’s is a very simple, but very versatile, example utilzing jquery, php and ajax to provide instant feedback to your guest.
Note: my approach uses the jQuery.post() method, which is equivalent to jQuery.ajax(). Learn more about jQuery.post().
Here’s the accompanying php:
And here’s a little demo I threw together to show an example of this in action. (sorry the demo is currently unavailable while I'm rebuilding the site!)
