In the last Designing with Code article, Converting Forms to Ajax, I showed you how to convert your standard web forms to Ajax by including a simple JavaScript object. In this article, I’ll show you how to handle the request on the server-side and then the response on the client-side.
The example project in this article can be downloaded here and viewed live here. We will learn how to create a login form, reroute the response through Ajax using the same technique learned in the previous article, handle the request on the server, return a response based on database values that were selected, and finally parse the data on the client side when the response is received. Although it’s not required, this article assumes that you have a basic understanding of JavaScript, PHP, and XML.
