That's not true, since he's using user data in the SQL statement. The query method has nothing to do with whether data should be escaped. Of course, addslashes() is sort of a last result with regard to escaping data for use in a query. The more preferable options are those native to the database you're using, if they exist. MySQL users can use mysql_escape_string(), for example.
