*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.php">click</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=foo&var2=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=foo&var2=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.
