userdata_postsave hook query

[Nullifi3d]

PHP Code:

$this->registry->db->query_write("UPDATE " . TABLE_PREFIX . "banners SET available = available + 100 WHERE userid = " . $this->registry->userinfo['userid']); 


This query gives users impressions each time they make a new post. I would like to change it so that it gives a different amount of impressions according to whether it's a new post or a new thread. How would I go about doing this?
