Re: [PHP] How know from wich page you came from
*SOME* browsers set a referrer script name/url, and some don't, so you can't rely on it. The solution can be as simple as including the referring script as a GET variable in the URL: a href=page.php?ref=anotherpage.phpclick/a Or, by keeping track of that sorta stuff with sessions... Whenever I *have to* know the URL of the preceding script, I take the directory, script name and query string eg dir/dir/page.php?var1=foovar2=bah and base64 encode it (so that the get vars don't register with / affect the receiving script), and pass it to the next page: ? $this_url = dir/dir/page.php?var1=foovar2=bah; $this_url = base64_encode($this_url); ? a href=page.php?ref=?=$this_url?click/a On page.php, I decode it all with base64_decode(), and I know exactly where the user came from. Similar (or even smarter) stuff can be done with sessions.

Re: [PHP] How know from wich page you came from
If you have control of the pages the visitor just left, then you should be able to modify the links there and pass forward a variable similar to the following. a href=newpage.htm?var=1 Then on your receiving page you can check the value of $var and do something with this info.
