RE: [PHP] refreshing PHP on onClick

It's all in a password protected site because the data's all confidential at this point in time, but I can give you a mental picture. There are a bunch of dropdowns - State, Cancer, Sex, Race, Age. We're drawing a graph of best fit lines - up to 5 allowed on the graph, then we start over replacing them. We don't draw the actual data points unless the user clicks on a checkbox. They want that checkbox to be instant gratification, without making the user refresh. I just want a way to make it do the refresh (and let me change that one variable, so it draws the points or doesn't draw the points), but not a full submit because that would add another line to the graph. I'm sorry I can't send you the URL at this stage of the game. it should be up and running this summer though :-) Thanks for any help you can give me!! -Natalie -----Original Message----- From: Robert Cummings [mailto:robert.cummings@webmotion.com] Sent: Thursday, May 16, 2002 3:56 PM To: Leotta, Natalie (NCI/IMS) Cc: php-general@lists.php.net Subject: Re: [PHP] refreshing PHP on onClick "Leotta, Natalie (NCI/IMS)" wrote: > > This might be a little bit JS and a little bit PHP.
