Because that's not atomic. (Between the time you retrieve the value and the time you set the new value, another query may have changed the value already.) Instead, you want to have the equivalent of the SQL... UPDATE table SET field=field+1 WHERE somecondition; ...where it all occurs in a single query. How to do this in CakePHP was recently asked in this group; here's one reply from that thread that shows one possible solution: http://groups.google.com/group/cake-php/msg/022622017dd329f8 -- Our newest site for the community: CakePHP Video Tutorials http://tv.cakephp.org Check out the new CakePHP Questions site http://ask.cakephp.org and help others with their CakePHP related questions.
