(which is why PHP calls its variable $_SERVER).
Is there a need for a {(server ...)} markup expression? Would it not be
more fitting to use page variables for things like the user's browser
name or the ip address? And then I would use terms like {$Browser} and
{$IPAddress}. Just a short while ago Pm gave a definition for use of
"browser" in conditional markup. Who would want to use {(server
HTTP_USER_AGENT)} as wiki markup?
Apologies for not having followed this thread and butting in.
A side note: I'm probably missing something here... but why not use
{$HTTP_USER_AGENT}... If it's a security concern, couldn't a $Enable...=0
clear the sensitive variables? You've probably talked about this, just
ignore in that case.
By suggesting that we use the actual names, I _am_ advocating for and
thinking of the non-programmers, because when a non-programmer does a
Google search for things like "how do I find out the user's browser?"
or "how do I find out the address a user is coming from?", that
non-programmer is going to find references to HTTP_USER_AGENT and
HTTP_REMOTE_ADDR and not 'browser' or 'ip'.
So a user who does not read much documentation, or does not memorise it
very well, tries to use {(server browser)} and this does not work. so he
will have to look up the meaning of {(server..)}, and finds mention of
HTTP_USER_AGENT. Then he is supposed to "google" on that term to get
more information?
Adding links to good W3 pages or similar that explain HTTP_USER_AGENT is
easier and faster for us. Writing good documentation takes a lot of time.
What the user probably wants most of all are examples of how to actually
use it...
To help a non-programming user it would be good to have a page variable
{$Browser}, which return a simple browser name, and perhaps also
{$BrowserVersion} to return a simple version info, good enough to do any
conditional switching.
I have never programmed to get different HTML for different browsers, but
I'm not sure it's that easy to categorize the browsers in a useful way.
Nor am I sure there are 'simple' browser names... at least when I've made
Opera identify as different browsers there seems to be a lot to choose
from.
So if we created our own categories of browsers (in terms of the simple
names), I suspect it'd be quite a bit of work to create, maintain and
document.
