[PHP] refreshing PHP on onClick
This might be a little bit JS and a little bit PHP. I'm wondering if there's an easy way to refresh a PHP page on an onClick and change one parameter (say someone wants to redraw the graph, but with the points). I don't want to pay attention to any of the other parameters that could have changed on the screen (we've got a bunch of selects). We had come up with a really complicated way which involved changing the parameters to the most recent line drawn, deleting the most recent line, and then submitting with those parameters and the showPoints value changed, but that sounds pretty complicated. If anyone could come up with a quicker way that didn't involve the whole submitting thing, that would be easier. My page has all of the vars that are necessary in hidden vars, and has HTML, PHP, and a handful of JS. Thanks! -Natalie Natalie S. Leotta Information Management Services, Inc.

Re: [PHP] refreshing PHP on onClick
I'm not certain I understand your situation. If you're trying to keep state between each new input then I would recommend PHP sessions to store your variables. Could you elaborate more what you're trying to do? -Kevin - Original Message - From: Leotta, Natalie (NCI/IMS) [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Thursday, May 16, 2002 1:48 PM Subject: [PHP] refreshing PHP on onClick This might be a little bit JS and a little bit PHP.

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:[EMAIL PROTECTED]] Sent: Thursday, May 16, 2002 3:56 PM To: Leotta, Natalie (NCI/IMS) Cc: [EMAIL PROTECTED] Subject: Re: [PHP] refreshing PHP on onClick Leotta, Natalie (NCI/IMS) wrote: This might be a little bit JS and a little bit PHP.

Since you're already using javascript... you could try generating 2 images at the same time, one with the data points drawn, the other without, then using the same technology as for javascript rollovers, you could replace the image when the onClick event is caught. Instant gratification, and no messy varable replacements.

RE: [PHP] refreshing PHP on onClick
This sounds like it might work. Thanks for your help!! I knew there had to be a better way than what my coworkers came up with :-) -Natalie -Original Message- From: Robert Cummings [mailto:[EMAIL PROTECTED]] Sent: Thursday, May 16, 2002 4:09 PM To: Leotta, Natalie (NCI/IMS) Cc: [EMAIL PROTECTED] Subject: Re: [PHP] refreshing PHP on onClick Leotta, Natalie (NCI/IMS) wrote: 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.
