Answer

You just need to add a button and an onclick handler for it.

Html:

Js:

$("#review").click(function(){
            var myData = $("#myform").serialize() + "&review=review";
            $.post('process.php', myData , function(data) {
                    $('#results').html(data);
                });
            }
        );

Since you have set a variable review here, you can use it to know that is call has come by clicking the review button.
