[SOLVED] How to get URL of previous page..

[Guest kilbad]

I have an authentication script which, currently, once someone logs in, will give a message stating they have been logged in successfully.  However, instead, I want to have it redirect the user to the page they came from. 

Therefore, I wanted to know how I can "grab" the last URL of the page the user came from?  If I have that, I could then redirect them back.

Thank you all so much in advance!

[code]<?
function get_referrer(){
if(!$ref=@$HTTP_REFERER) $ref=$_SERVER['HTTP_REFERER'];
return $ref;
}
echo get_referrer();
?>[/code]

Thanks for the quick response!

I posted your script at [url=http://www.kilbad.com/DEVELOPMENT/test.php]http://www.kilbad.com/DEVELOPMENT/test.php[/url], but it is giving me some weird behavior.. not echoing the page when I come from somewhere else on kilbad.com..

and ideas?

Thanks again!

works for me. the $_SERVER['HTTP_REFERER'] works via hyperlinks, so simply just going to a different address/hitting the back/forward buttom won't have the desired effect as far as i know.

I tried the link you provided. I also skipped to http://www.kilbad.com/DEVELOPMENT/ and clicked on the test.php link, and all worked fine.

I believe some browsers can be set up to mask the HTTP_REFERER though, so it'd be worth checking whether thats why it's not showing it for you.

works here also... and the HTTP_REFERRER is sent along with the headers, so any/all new browsers (anything after ie4) should support it... and it will only work for links, going directly there or refreshing without cache wont work.
