Recently one of our clients was in need of the ability to upload files to their webserver. This was easily accomplished with PHP’s built in functionality. But the draw back to this approach was that end-user had little or no indication that anything was happening.
Now we all know what happens. Typical scenario: User clicks a button. Seemingly nothing happens… *click*…. *clickety-click*… *CLICK CLICK CLICK*. Refresh, Reload. We all know how impatient some people can get. Specially when they don’t see the immediate gratification that is seeing something react when you push a button.
