Is it possible to submit a variable via HTTP_POST_VARS or some other method to determine if the previous form's data has changed? I have an HTML form and several text fields produced through a MYSQL query and stored in an array. If any of those text fields are changed, I'd like to update some global variable so that when posted using $PHP_SELF, the new form knows the previous form has been updated.
there are 2 ways to go I know of
i) set a hidden variable the same as the input and check they match
ii) set a hidden variable in the onchange() for that input
If it's real important put a checksum alongside it
Any problems mail us
