PHP redirect:header but with AJAX

Vote count:

A PHP script I have written currently uses a redirect:header to move you onto the next page.

It is a login form, and if successful it takes you to register-succes.php. if unsuccessful (things weren't filled in correctly) it stores an error message in a session and reloads you back into register-form.php to try again.

Originally this was working absolutely fine, because all the pages where separate (like register-success.php was it's own page with full HTML).

But I have since changed it so that you stay on the same page and the main div is loaded in via AJAX. This means that using a redirect no longer works.

This, at present is the successful redirect of the form:

if(register($email_address, $username, $password) === true){

        // Sends an email
        send_email($email_address);

        $succeeded = true;

        header("Location: register-success.php?username=$username");
        exit;
    }

Instead of the simple redirect, how can I have this just reload register-succes.php through AJAX, something like below, but in PHP?

var xmlhttp;
if (window.XMLHttpRequest)
  {// code for IE7+, Firefox, Chrome, Opera, Safari
  xmlhttp=new XMLHttpRequest();
  }
else
  {// code for IE6, IE5
  xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
xmlhttp.onreadystatechange=function()
  {
  if (xmlhttp.readyState==4 && xmlhttp.status==200)
    {
    document.getElementById("login-register-wrapper").innerHTML=xmlhttp.responseText;
    }
  }

xmlhttp.open("GET","register-success.php",true);
xmlhttp.send();
