How to get a database value to the config file?

I need a system with changeable themes, so I need to get the active/current theme from the database to the config file from where I can access it in helpers and controllers. How do I do it???

Setting a Config Item
If you would like to dynamically set a config item or change an existing one, you can so using:

Code:

$this->config->set_item('item_name', 'item_value');

Where item_name is the $config array index you want to change, and item_value is its value.

will it be accessible to multiple controllers/modules in HMVC?
