Ajax call accurately sets $_SESSION variable, but page reload does not work

I've been trying to impliement something that is supposed to be easy and straighforward for some time now, but have not succeeded. I am somewhat close now and need a little help with the last step.



Clicking on a link (<a> tag) should execute a php code that sets a $_SESSION variable and displays the result to the user without reloading the page



I can click the link (I changed it to a layer instead, but the same rule applies) and it executes the desired php code and properly sets the $_SESSION varaible. However, I have to manually click the reload button on the browser in order for the browser to show the contents of the $_SESSION variable


I have tried to add various reloading methods (location.reload() for example) but that does not work. I'll simplify the code;



<?php  session_start();  ?>


function loadurl(dest) {

    try {
        xmlhttp = window.XMLHttpRequest?new XMLHttpRequest(): new ActiveXObject("Microsoft.XMLHTTP");
    } catch (e) {
        alert("Something went wrong here");
        xmlhttp.onreadystatechange = triggered;
        xmlhttp.open("GET", dest);

function triggered() {
    if ((xmlhttp.readyState == 4) && (xmlhttp.status == 200)) {

        document.getElementById("ajaxlink").innerHTML = xmlhttp.responseText;
//    location.reload();



<div id="ajaxlink" onclick="loadurl('actions.php?action&q=1')">Click Here</div>

<?php echo $_SESSION['person']; ?>



if (isset($_GET['action'])) {
    $q = mysql_real_escape_string(trim($_GET["q"]));

    $query = "SELECT * FROM user WHERE id='$q' LIMIT 1";
    $result = mysql_query($query);
    $row = mysql_fetch_assoc($result);

    $_SESSION['person'] = $row['FirstName'] . ' ' . $row['LastName'];
