        $title = $_POST['t'];
        $idea = $_POST['i'];

        if (!empty($title) && !empty($idea)) {
            $query = "INSERT INTO `updates` VALUES ('".mysql_real_escape_string($title)."')";
            if ($query_run = mysql_query($query)) { } 
            else {
                echo 'Sorry ,we could\'t register you at this time.Try again later';
            } 
        }                    
    }

Clear your post data after insert in db. Add below code after insertion db code.

$_POST = array();

like inside your if block

... 
 if ($query_run = mysql_query($query)) { $_POST = array(); } 
...
