Save it into session, but first of all, change the value attributes, so they are unique.

Then you can make a standard or Ajax request to your PHP script, which reads product identifier, and saves it into session. In PHP, you can read radio value just like other input fileds - it will be in $_REQUEST (better use $_POST or $_GET), containing value that is present in value attribute of radio button user had chosen.

Example PHP code (please implement more security mechanisms before using):

<?php
     session_start();

     $itemId = $_POST['rmr'];

     if(!empty($itemId)){
        $_SESSION['cart'][] = $itemId;
     }
?>

That is the most simple example I can give you ;)

Nice day

Update:

First, change you html to something like that:

<form method="post" form name="make_payment_frm" action="module/make-payment-module.php" onsubmit="return show_make_payment_validation();"> 
      <input name="rmr"  type="radio" value="1" onclick="get_radio_value()" /> royal<br />
      <input name="rmr"  type="radio" value="2" onclick="get_radio_value()" /> splroyal<br />
      <input name="rmr"  type="radio" value="3" onclick="get_radio_value()" /> postal
</form>

Then, you have two options: first one is to send data via AJAX. You'd do that in Javascript, in show_make_payment_validation() function. If you're using jQuery, request would look something like that:

$.post('module/make-payment-module.php', {rmr : $('name="rmr"').val()}, function(data){
   // callback
});

and read it in PHP just like I described above. If you're using other JS framework or none at all, take a look at XmlHttpRequest.

Second is to get rid of that function and post directly. Then, in PHP, you access the data as I mentioned before, $_POST['rmr'] is you cart item (it'll be 1 if royal is selected, 2 if splroyal and 3 if postal).
