Bug #10965: session_register() doesn't work after session_id(n)

From: averma@lvision.com Operating system: linux 2.2.14 PHP version: 4.0.4 PHP Bug Type: *Session related Bug description: session_register() doesn't work after session_id(n) I am implemeting an e-commerce site with credit-card processing done by an external payment processor. Right now I am evaluating itransact.com. They have a feature where I can send a ret_addr (a full url of a script on my server, say, fromPP.php) and variable name/value pairs to them when I "submit" a form. Then they do a POST to fromPP.php and pass the variables as POST variables along with the status code etc. One of the variables I am passing is the session id, say, SESSid, when I submit the form to their site. The idea is to maintain the state in fromPP.php by doing a session_id($SESSid). I am able to get the right SESSid from the payment processor and after doing session_id($SESSid) I am able to access all session variables declared before submitting the form, but when I try to register new session variables in fromPP.php, for example, by calling session_register("FROMPP_xid"), nothing happens. There are no errors but this variable does not actually get registered. If I start a new session in fromPP.php, then it works fine, but I lose the state. This looks like a bug to me. -- Edit Bug report at: http://bugs.php.net/?id=10965&edit=1
