Re: Most portable back button in php

Well, this is a bit different from what I was talking about (internal site navigation). And has nothing to do with PHP_SELF. In this (I'd say - rare case) you would do: if http_referer contains "myprimary.com" print back link using http_referer else do nothing or put the link to some other appropriate page endif HTH, Stas ----- Original Message ----- From: "Henry" <henry@teacake.f9.co.uk> To: <php-general@lists.php.net> Sent: Thursday, August 08, 2002 4:40 PM Subject: Re: [PHP] Most portable back button in php > I have an idea then. > > How can I best generate a full URL from PHP_SELF and other variables on the > referrer page such that I can generate the back link on the page I get to > even if the referrer page is on a different server? > > as an eample if I know that the page to go back to will be at > http://www.myprimary.com/referrer.php and I generate a page at > http://www.mysecondary.com/info.php I can ensure that there is > the following > html in place > > <a > href="http://www.myprimary.com/referrer.php">go > back</a> > > TIA > > Henry > > "Stas Maximov" <maximov@eircom.net> wrote in message > news:008601c23eef$cc25f260$ec000064@nexus... > > Yes, indeed.
