PHP 5.2.13
I'm trying to capture a visitor's IP address in a web form (a ballot
for club office) and am coming up empty handed. Purpose is to head
off ballot box stuffing. All sorts of Googling keeps coming up with
the following...
<input type="hidden" name="ip"
value="<?php echo $_SERVER['REMOTE_ADDR'] ?>">
which just gives me the literal PHP script between the double quotes
instead of the voter's IP address.
Help please?

Is this on a page with a .php extension? Is your web server set up to
parse php files?

Oh crap! HTM extension. And I know better! Changed the extension,
works fine now. Thank you, Jerry!
I'm a small step or two above the novice level, but I've been using
PHP and MySQL for very simple tasks long enough that I knew something
was seriously strange when the above wouldn't work. Didn't think the
answer would be quite so embarrassing.
Thanks again.

No. $_SERVER already is a variable.

Nice to have it sorted yes.
Is there some reason that the ip address would be necessary to
place in a hidden input? Open to anyone that may take the time to
look and possiblely edit the source.
Can it not be taken when the form is processed?

A conclusion is the place where you get tired of thinking.

Whilst this is a better idea, there is not much point taking it anyway
since the ip address in
$_SERVER['REMOTE_ADDR'] is not unique to a visitor. Anyone sitting
behind the same NAT Router or Proxy (used by many business) will share
the same value.

Yes. I moved it to the form handler where it's all PHP and can't be
inspected.

True, but we'll be collecting other data that when combined with IP
will prevent irregularities in the voting.
