include in library

[eluser]tonanbarbarian[/eluser]
base_url will return just that, a URL
so if you use it with an include it will be trying to do the following

Code:

include( base_url().'include/calendar/datepicker.php');

=

Code:

include( 'http://www.example.com/include/calendar/datepicker.php');

Instead you probably want to use one of the predefined path constants such as
BASEPATH
or
APPPATH
