Subject: Current page link variable?
It's killing me, I can't figure out how to get the current page URL in a plugin.  I'm trying to add the opengraph details for every page to a plugin, and I'm getting the results I expect, except the URL.  Is there a global variable that does this?  The template vars are not always available, so what works in a post might not work in a thread or a forum view, etc.

I've spent ages on it, and can't work it out.  Any hints? =)

Tried something from the $_SERVER space, like $_SERVER['PHP_SELF'] (formerly $PHP_SELF or so) or one of the HTTP_* entries? There's no UNB special for that. You need to go down to PHP.

That worked perfectly, thanks Yves!

For anyone who wonders, I used

$_SERVER['PHP_SELF']

followed by

$_SERVER['REQUEST_URI']

Note that PHP_SELF contains the absolute path of the file on the server's filesystem. You shouldn't want to expose this to the user. REQUEST_URI should be the very URL that was requested by the browser, so this should be better suited for your described requirement.

Actually PHP_SELF is just the filename of the script, relative to document root.  So my string is:

  1. $string = 'http://domainname.com' . $_SERVER['PHP_SELF'] . $_SERVER['REQUEST_URI'];

and the result is

http://domainname.com/path/to/script.php?any&additional&args

If it was the filesystem path it wouldn't be very useful at all.  =)

Alright. My memory must have fooled me. I haven't been using such low-level things for a time.
