Question

For some odd reason Internet Explorer won’t run my queries properly.
I designed this web application on Firefox, everything runs smooth over there, the only problem is in Internet Explorer. I have a Perl script which inserts status messages into a table called tbl_messages. Since the Perl script is being handled by an Ajax call, you won’t see a thing of that. Now where it goes wrong is after the first message, it does update ‘gezien’ to 1, but yet it seems to show the same message over and over again.

This is the status page

include('actions/classes.php');
mysql_select_db('st_beheer');
$dbres      = mysql_query("SELECT id, message FROM tbl_messages WHERE uniekid=".$_GET['uniekid']." AND `gezien` = 0 ORDER BY id LIMIT 1") OR DIE (mysql_error());
$message    = mysql_fetch_assoc($dbres);
mysql_query("UPDATE tbl_messages SET gezien = '1' WHERE id='".$message['id']."'") OR DIE (mysql_error());
echo var_dump($message);

And over here the ajax calls

<script>
    $(document).ready(function(){
        var post = $('#f_export').serialize();
        $.ajax({
          type: "POST",
          url: "export.pl",
          data: post
        });

        var timer = setInterval(StatusUpdate, 1000); 
        var uniekid = $('#uniekid').val();

        function StatusUpdate() {
            $.ajax({
              url: "status.php?uniekid="+uniekid,
              success: function(data){
                $('#progressie').append(data);
              }
            });
        };
    });
</script>

Under your Ajax call include cache: false property

function StatusUpdate() { 
        $.ajax({ 
          url: "status.php?uniekid="+uniekid, 
          cache:false,
          success: function(data){ 
            $('#progressie').append(data); 
          } 
        }); 
    };
