    Use cookies or store on a server.

    You couldn't.

    But you could use cookies.

    If the page is server based, then you could use sessions as well or ($POST and $GET) request.

    Sorry for double post, but here's a stripped-down version of my webpage:

    PHP Code:
    <html>
    <head>
    <script type="text/javascript">
    function flag(id,btn) {
    var divid = id;
    var abtn = btn;
      document.getElementById(divid).style.background="#F0D7D7 url('display-bg-flagged.png') repeat-x";
      document.getElementById(btn).href="javascript:unflag('"+divid+"','"+abtn+"')";
    }
    function unflag(id,btn) {
    var divid = id;
    var abtn = btn;
      document.getElementById(divid).style.background="#F0F0F0 url('display-bg.png') repeat-x";
      document.getElementById(btn).href="javascript:flag('"+divid+"','"+abtn+"')";
    }
    </script>
    </head>
    <body>
    <?php
    echo "<div class=\"post\" id=\"".$r['id']."\" name=\"flag\" style=\"background:#F0F0F0 url(display-bg.png) repeat-x;\">";
    echo 
    "<a href=\"javascript:flag('".$r['id']."','flagbtn".$r['id']."');\" title=\"Flag Feedback\" id=\"flagbtn".$r['id']."\"><img src=\"flag.png\" border=\"0\"></a>";
    echo 
    "<div class=\"message\">".$r["message"]."</div></div></div>";
    ?>
    </body>
    </html>
    The $r['xxxxx'] parts get a MySQL value, I didn't bother putting it in though.

    Could I make it so that when I press the link, a value gets added to the specific row.
