I have form that when submitted it uses AJAX and its posts data to reg1.php. I want it to do some bits with the data posted and then redirect to a page to use it. 
When I redirect after how do I post the posted data with it to list.php?
 Or is there another way of doing it?
<script>
$(document).ready(function () {
  $(".loginform").submit(function() {
    data = $("#loginform").serialize();
    $.ajax({
      type: "POST",
      url: "reg1.php",
      data: data,
      success: function(result) {
          if (result == 'success') {
            //$('.output_message').text('Message Sent!');
            //$('#loader').hide();
            alert("SUCCESS");
                window.location.replace("list.php");
          } else {
            //$('.output_message').text('Error Sending email!');
            alert("NO SUCCESS");
            //$('#loader').hide();
          }
      }
    });
    return false; 
  });
});
</script>
