codeigniter how to connect second database based on dynamic values

I want to import data from other database with dynamic connection
in codeigniter user input the database credential in the form and than I want to connect that database and import some data in the primary database. the question is how to set the second database connection with the dynamic values.

this is your first db connection from application/config/database.php
$db['default'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'first_db',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
and this is second db connection function from model or controller or helper your choice.
private function second_db(){
return $db['second'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'second_db',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
}
private function first_db(){
return $db['second'] = array(
'dsn' => '',
'hostname' => 'localhost',
'username' => 'root',
'password' => '',
'database' => 'first_db',
'dbdriver' => 'mysqli',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => 'utf8',
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
}
if you set up your settings then you can switch your database with this code
$this->load->database(first_db(), TRUE);
$this->load->database(second_db(), TRUE);

In application/config/databse.php

How to connect more than two databases in codeigniter

I want connect to 3 databases. I don't have any problem if i connect just two databases. When i try to connect 3 databases. i have problem like i cant connect to database two.
this my config at database.php :
$db['default'] = array(
'dsn' => '',
'hostname' => '192.168.11.29,1433',
'username' => 'userhsp',
'password' => 'hsp432#',
'database' => 'HSP',
'dbdriver' => 'mssql',
'dbprefix' => '',
'pconnect' => TRUE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => FALSE,
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
$db['crm'] = array(
'dsn' => '',
'hostname' => '192.168.11.29,1433',
'username' => 'userhsp',
'password' => 'hsp432#',
'database' => 'CRM',
'dbdriver' => 'mssql',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => FALSE,
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
$db['pltapol'] = array(
'dsn' => '',
'hostname' => '192.168.11.29,1433',
'username' => 'userhsp',
'password' => 'hsp432#',
'database' => 'pltapol',
'dbdriver' => 'mssql',
'dbprefix' => '',
'pconnect' => FALSE,
'db_debug' => (ENVIRONMENT !== 'production'),
'cache_on' => FALSE,
'cachedir' => '',
'char_set' => FALSE,
'dbcollat' => 'utf8_general_ci',
'swap_pre' => '',
'encrypt' => FALSE,
'compress' => FALSE,
'stricton' => FALSE,
'failover' => array(),
'save_queries' => TRUE
);
and in my model like this :
private $db2;
private $db3;
public function __construct()
{
parent::__construct();
$this->db2 = $this->load->database('crm', TRUE);
$this->db3 = $this->load->database('pltapol', TRUE);
}
i just can get object from database pltapol, but i dont get object from crm. how to fix it?

I want to answer my question. i tried to use
$this->db2->db_select() or $this->db3->db_select()
if i want to use that connection before $this->db2->query() or before $this->db2->query()
that is work!
happy coding :)
