Re: cookie/cache weirdness

> completely empty posts (and all the fields are NOT NULL), which is REALLY There really isn't enough into to answer the other stuff -- show some source code maybe... But you're not correctly understanding NOT NULL. An empty string is not the same as NULL, so you can put something like this: insert into whatever (required_field) values('') and the database will be perfectly happy. Only this will make it complain: insert into whatever (required_field) values(NULL) If you want to disallow the empty string, you'll need to do that in PHP.
