Using Multiple Databases Within CodeIgniter
in your database config file add as many configuration groups as the numbers of your databases:
$db['a']['hostname'] = 'localhost';$db['a']['username'] = 'user';$db['a']['password'] = 'pw';$db['a']['database'] = 'db1';...$db['b']['hostname'] = 'localhost';$db['b']['username'] = 'user';$db['b']['password'] = 'pw';$db['b']['database'] = 'db2';...//set the default db$active_group = 'a';then on your model initialize a class variable:
private $db_b;and, into the contructor, set it as follow
__construct(){ ... $this->db_b = $this->load->database('b', TRUE); }now you are able to use the database b as usual:
$this->db_b->query('YOUR QUERY');and obviously the default one as follow:
$this->db->query('YOUR QUERY');
