I want to post the PHP variables `$uid` and `$submissionid` to the file fblike.php. Is the Ajax below formatted correctly to do this?

```
<?php

ob_start();
session_start();

$uid = $_SESSION['loginid'];

$submissionid = mysql_real_escape_string($_GET['submissionid']);
$_SESSION['submissionid'] = $submissionid;

?>

<head>

<script type='text/javascript' src='jquery.pack.js'></script>
<script type='text/javascript'>
$(function(){
    $("a.connect_widget_like_button").live(function(){

        $.ajax({
            type: "POST",
            data: "action=vote_up&uid="+$(this).attr("uid")"&submissionid="+$(this).attr("submissionid"),
            url: "fblike.php",

        });
    });

}); 
</script>

</head>

```
