2 jamroom sites, 1 database
Installation and Configuration
Haven't done it so don't have the code for you, but for concepts I would test to see if these were possible:
* use the events and listeners system to pick up on any request to the 'settings' table and change its destination database. (i worry that might effect the other tables too though.)
* During the jrCore_init() function the /data/config/config.php file brings in all of the connection information. When settings stuff is coming in, change the variables for $_conf['jrCore_db_name'] $_conf['jrCore_db_user'] and $_conf['jrCore_db_pass']. Same issue as above though, how to do it for just the single table you're interested in.
* maybe store the settings table in a third separate database and make a script so that both sites are connecting to the same 3rd database which would mean the same codebase on both sites.
* maybe use a different prefix. inside the jrCore_db_table_name() function that goes and gets the correct database table name, have a different prefix for each site, but a single actual database. then you'd just need to adjust the
$_conf['jrCore_db_prefix'] to determine which database to use. This probably has the most merit I would think.
