How to redirect from header after login?

[kickindaspeaker]

I'm designing a web site in html and PHP, and all pages contain a header that is included at the top of every page.

However, the header contain a logging in/out form. Right now, when a user logs in/out, he is redirected to the home page of the site. Instead, I would like the visitor to just "stay" where he is (wether he's on the forum page, posting a reply, or on any other page of the site).

The redirection is determined in the login form by the following line of code:

<input type="hidden" name="redirect" value="{U_INDEX}" />

Where {U_INDEX} is the home page's URL. So I guess what I need is for the header to figure out on what page it is, and put that URL in a {U_REDIRECT} variable that will be my new value for that hidden field.

Any ideas?

well, am not sure, wheter this helps,
but just try it anyway

replace {U_INDEX} into $_SERVER['REQUEST_URI']

nope 🙁

And I have tried with REQUEST_URL instead of URI, but no dice either!

and what happened? you are still redirected to the first page?

no, it simply puts http://mydomainname.com/$_SERVER['REQUEST_URI'] in the browser's url field!
