I have to use two databases in a controller. Even though I load the second database with second parameter TRUE to get reference without overwriting the default database it is replacing the default database. Any idea what should be done when loading the second database. Currently I am loading like below.
$testDB = $this->load->database('preview',TRUE,FALSE);
set the pconnect param of both db to false
$db['preview']['pconnect'] = FALSE;
in your config/database.php
then on your model which is connecting to the second database, load it like this:
class Example_m extends CI_Model {
function __construct(){
$CI =& get_instance();
parent::__construct();
$this->db = $CI->load->database('preview',TRUE);
}
//this will work sure or check your errors
//If you use group
//group name
$preview_DB = $this->load->database('preview',TRUE);
//another DB
$another_DB = $this->load->database('another',TRUE);
//if You use array
//create connection string
$db = array();
$db['hostname'] = "database_hostname";
$db['username'] = "database_username";
$db['password'] = "database_password";
$db['database'] = "database_name";
$db['dbdriver'] = 'mysql';
$db['pconnect'] = FALSE;
$DB = $this->load->database($db,TRUE);
I assume you've made the required configuration in your database.php
you can load your 2nd database like this:
$testDB = $this->load->database('preview', TRUE);
and use it like this:
$query = $testDB->query("SELECT * FROM TABLE");
