$this->db->where

That depend on the type of the condition.
is this either: WHERE id=a OR id=b OR id=c
or: where id=a AND id=b AND id=c
or: where id IN (a,b,c)

Have a look at the tutorial:
https://www.codeigniter.com/userguide2/d...tml#select
look at or_where, where_in, etc depending on what you try to do

WHERE id=a OR id=b OR id=c is what I meant


Thanks
