[PHP] Fussy logic...
Moin! Has anybody already thought about the problematic conditional on adding an automatic BACK Link? It seems to be very easy... just Link to basename($HTTP_REFERER); BUT if you CLICK on this Link, and come to a prior site, the BACK-Link THERE appears NOT to the PAGE, witch was prior this, but is linked to the Site you come from... so the link should better be called FORWARD. Do U C the problem??? ;) Has someone an idea to solve it?

Sincerely yours, Patrick Lehnen (alias: Tribun) Patrick, It's pretty obvious that after using it once it becomes a forward link because the HTTP_REFERER is the page you last came from. And after using the back-button once, the last page was the 'next'. The HTTP_REFERER isn't some kind of history-list. If you realy want to go Back, why not use: JS: history.back(...); That way you really use the history-list of the browser. So after using it once, it's still a Back-button instead of a Forward-button. Besides that, using the $HTTP_REFERER isn't really something to rely on. $HTTP_REFERER doesn't always have to be set. In that case you can't go either Back nor Forward. -- * RzE: -- -- Renze Munnik -- DataLink BV -- -- E: [EMAIL PROTECTED] -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- H: +31 23 5516190 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- -- http://www.datalink.nl -- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Well... then you should store the history yourself (eg. in a session or db). But then again... the $HTTP_REFERER isn't something to rely on. So then you'll need to store the current page in the history session/db. That way you always have the correct URL because it's the URL of the page the user is using. How much can go wrong with that? I think that's the best way. Actually I think it's even (a lot) better then the JS solution I mentioned. -- * RzE: -- -- Renze Munnik -- DataLink BV -- -- E: [EMAIL PROTECTED] -- W: +31 23 5326162 -- F: +31 23 5322144 -- M: +31 6 21811143 -- H: +31 23 5516190 -- -- Stationsplein 82 -- 2011 LM HAARLEM -- -- http://www.datalink.nl -- -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]
