[Nfb-web] setting divs

[Bryan Schulz]

Hi,

Yes, that was the first attempt when selecting a radio or select choice on a
form called a java script function and I couldn't make the script react as
expected so ditched it.
I went with submitting the choice to a page similar to the first one and
displaying content works with php and post/session values and if conditions.
The decision was also influenced by needing to hand files to someone else.
Thanks,
Bryan

Good afternoon Bryan,

I'm not entirely sure I am clear on what you're trying to accomplish.
Are you trying to use PHP to dynamically show a div without a page
reload? Most of the time this is done with JavaScript which has the
ability to manipulate the page as it exists in the browser. As far as I
am aware, PHP, being server side, can only execute code before the
browser renders it to the user. JavaScript is client side and can make
these kinds of changes.

I can show you a couple examples of how to do this, I just want to
ensure I understand your use case first.

Thanks,
Rachel
