PROBLEM Correct way to post form data in ajax

[vish93]

There's a form plugin: http://get-simple.info/extend/plugin/imforms/1121/

Came across it yesterday but not really suitable for what I am after. You also have to run at least PHP 5.6.0 on your server.

I have in a new theme.php file created my form that I will display. Then collect the responses and show in backend admin plugin page.

I just need to figure what is the correct way in getSimpleCMS to handle ajax posts, as a php file in my theme folder doesn't seem the best solution.
