Loading in iframe on ajax form submit
I think that you can do it with jQuery.


Add this code in your template: &lt;iframe id="frame-id" src="" frameborder="0"&gt;&lt;/iframe&gt; 
Add this jQuery:

$("#SUBMIT-ID").click(function(e) {
  e.preventDefault();//This prevents the site from being redirected.
  var a_href = $('.A-THAT-HAS-REDIRECT-CLASS').attr('href');
  $("#frame-id").attr("src", a_href);
});
