give your form an ID like id="form"

put your includes/emailchange.php as your form action (do not require it). You will need to address it properly in your form action and in the javascript below.

At the bottom of your page you need to put this between script tags

$(function () { "use strict"; $("#form").submit(function () { var data = $('#form').serialize(); $.ajax({ url: "includes/emailchange.php", data: data, type: "POST", success: function (msg) { $('#display').html(msg).delay(6000).fadeOut(1000); } }); return false; });

});

This is to get you started. Work on it and change it as you see necessary
