accessing config variables from helpers or library

And further, if you're using a library, instead of a controller or model, you won't have direct access to the CodeIgniter instance.

You'll have to use code like this, instead of the standard $this->config->item(...);

Code:

$CI =& get_instance();

$CI->config->item('base_url');
