<?
    if(isset ($user))
    {
echo "<form action='?log=work.php' method='post'>
<input name='60' type='submit' value='60лева' />
</form>";
if(isset ($_POST['60']) == 1)
{
 $money = 60;
    $q =  mysql_query("UPDATE users SET points + '$money' WHERE username='$user'") or die(mysql_error());

    }

    }
 else {
     


    ?>

Проблема ми е че искам да се добавят парите към точките !
като имам 60 точки да ми даде още 60
също искам да направя лимит по 20 пъти да може на ден
