note 73107 added to function.setcookie

something that wasn't made clear to me here and totally confused me for a while was that domain names must contain at least two dots (.), hence 'localhost' is invalid and the browser will refuse to set the cookie! instead for localhost you should use false. to make your code work on both localhost and a proper domain, you can do this: <?php $domain = ($_SERVER['HTTP_HOST'] != 'localhost') ? $_SERVER['HTTP_HOST'] : false; setcookie('cookiename', 'data', time()+60*60*24*365, '/', $domain, false); ?> ---- Server IP: 216.194.113.175 Probable Submitter: 172.207.22.131 ---- Manual Page -- http://www.php.net/manual/en/function.setcookie.php Edit -- https://master.php.net/note/edit/73107 Del: integrated -- https://master.php.net/note/delete/73107/integrated Del: useless -- https://master.php.net/note/delete/73107/useless Del: bad code -- https://master.php.net/note/delete/73107/bad+code Del: spam -- https://master.php.net/note/delete/73107/spam Del: non-english -- https://master.php.net/note/delete/73107/non-english Del: in docs -- https://master.php.net/note/delete/73107/in+docs Del: other reasons-- https://master.php.net/note/delete/73107 Reject -- https://master.php.net/note/reject/73107 Search -- https://master.php.net/manage/user-notes.php
