http_referer/back button function

[mwdrago]

Hi everyone! can anyone tell me a good and reliable way to put a back button/link on the pages on my site? I want users to be able to click a link that takes them to the last page they viewed.

I tried <a href="<? echo $http_referer; ?>"> but that just took them to the folder that the current page resides in.

I think what your looking for is $SERVER['HTTP_REFERER']

<a href="<?php echo $_SERVER['HTTP_REFERER']; ?>">Link</a>

when I'm at localhost/pages/profile.php?id=4 that link sends me back to localhost/pages for example, when that's not the last page I was at.(localhost/member_directory.php was where it should've sent me)

May I also note that if this is all your using PHP for I'd reccomend using JavaScript instead. The code will bring the user back one page when clicked.

<a href="JavaScript:history.go(-1)">Link</a>

There is also no space between java and script in the link, its all one word but the page displays it wrong.

hey, I don't care, whatever gets the job done. Thanks a lot, that works great. Maybe I'll have to learn some javascript now.
