I'm looking for a way to integrate my Joomla site with a WordPress blog. What I want to do is have the users log in once on the Joomla site, and this authenticates them on the other systems joined to it.
It's a bit of a web2.0 mega-mashup, with Joomla as portal, a PHPBB, MediaWiki, and there might end up being some more systems added on. I'm aiming to add WordPress support, which essentially means that I need to create a new WordPress user whenever a Joomla user is created (Which I think I can do with a few SQL queries), and the part that I haven't figured out yet: It needs to log users into the WordPress site when they log into the Joomla site. Can anyone help?
I could probably figure it out if I look at the login page and trace all the function calls etc back to where it sets the cookie, but that might take a really long time, and I'm hoping to pull this off without reinventing the wheel.
If anyone can help, I'd really appreciate it, thanks for reading.
