Hi all,

I would like to use the typical $_SESSION[] that I have been using in php, but when I try to use in a media wiki extension, specifically in a special page disappears. This is, I want to store one variable in the $_session, one special page is showed, and then when other special page is showed in that computer and with this session, to access to this variable. How I can do that, what is the proper way to store and work with session in extensions??

Thanks in advance, David.

You could use the $_SESSION[] global variable directly or use WebRequest::getSessionData(). In special pages you should check, if the session is already set up, e.g. like SpecialUserlogin.php does it: https://github.com/wikimedia/mediawiki/blob/master/includes/specials/SpecialUserlogin.php#L247-L249
