Well, you need to use the javascript / ajax.

Example: on your submit link (a href for exaple), add call-in-to js function submitMe and pass on whatever variables you need

function submitMe() {
    jQuery(function($) {    
        $.ajax( {           
            url : "some_php_page.php?action=getsession",
            type : "GET",
            success : function(data) {
                alert ("works!"); //or use data string to show something else
                }
            });
        });
    }

IF you want to change some content dynamically, it is easy- you just need to create tags, and assign ID to them :

Then you load ANYTHING between those two tags using

document.getElementById("Dynamic").innerHTML = "BOOM!";

Meaning that you calling area between two tags and loading something into them. The same way you GET data from that place:

alert(document.getElementById("Dynamic").innerHTML);

In addition, play and experiment with DOM elements and learn how they interact. It is not hard, just takes some time to grasp all concepts.
