如何在具有多个数据库的CodeIgniter中存储数据库会话？

Question

I am using codeigniter and till date I was using cookie based sessions.. but now size of sessions is increased so i need to store them in database..

I have multiple database(more than 3) connected to my application..How can i specifically use ci_sessions table to store sessions?

when i say $config['sess_use_database'] = TRUE; my app goes blank. a plane white page is shown.

That is because From multiple database connections codeigniter is not finding exact database to store sessions..

How can i achieve the same? Thanks

Looking at the session code from system/libraries/Session.php, one can see that it uses the default $this->db to connect to the database for storing sessions.

Try modifying your database groups such that $this->db works. Alternatively, you can extend the Session.php such that you can pass it the database group for storing sessions.

Hope this gets you started in the right direction.
