PHP has no notion of what your application consists of. When you submit a form PHP has no idea whether it came from window1 or window2 or wherever. > Hence, if I have fields > in multiple windows that have a common name (e.g. I have two modules, > each of which requires a field called client name) posts from different > windows will overwrite the last post of a field with that common name, > regardless which window it came from. Even if you submit the same form twice in rapid succession nothing will get overwritten. Each request (submission) starts a new instance of php with it own copy of the form data. -- Jason Wong -> Gremlins Associates -> www.gremlins.biz Open Source Software Systems Integrators * Web Design & Hosting * Internet & Intranet Applications Development * ------------------------------------------ Search the list archives before you post http://marc.theaimsgroup.com/?l=php-general ------------------------------------------ /* What about WRITING it first and rationalizing it afterwords? :-) -- Larry Wall in <8162@jpl-devvax.JPL.NASA.GOV> */
