Connect and log in to a different database in codeigniter - php

Question

I am trying to connect to a different database. I have a script for creating a new instance from an SQL file. I am creating users by inserting into the main database table and then using the same database as the master login table with all the users. I am trying to login to another database and use that database. I am getting a blank home page on trying to login to another database and also in some cases I am not able to connect to another database at all and end up using the same master db. I am storing the company name in a session and using it in all model files and connecting to the db. I tried everything but nothing seems to work. My controller model and view files are as follows:
model: mod_login.php
<?php
class mod_login extends CI_Model{
var $myTables;
#print_r($this->db->last_query());
function __construct(){
parent::__construct();
$companyName = $companyName = $this->session->userdata('company');
$otherdb = $this->load->database("$companyName", TRUE);
$this->myTables=$this->config->item('myTables');
$this->load->helper('cookie');
}
function validate_admin_login(){
$this->form_validation->set_rules('username', 'Username', 'trim|required');
$this->form_validation->set_rules('userpass', 'Password', 'trim|required');
if ($this->form_validation->run() == TRUE){
return $this->check_admin_login();
}else{
return validation_errors();
}
}
function check_cookie_login(){
$this->db->where('username', trim($this->input->cookie('uusername')));
$this->db->where('userpass ', sha1(trim($this->input->cookie('userpass'))));

It displays the home.php but it displays a blank page without errors
