Add another controller in codeigniter - php

Question

Hello I'm currently facing a problem of adding another controller and the problem is that
I have 2 controllers
class 1st_Controller extends CI_Controller {
}
and
class 2nd_Controller extends CI_Controller{
my 2 models are working perfectly fine and the only problem is that I need to call 1 model per each controller
for example
1st controller is for 1st model and 2nd controller is for 2nd model.
Now what I've tried so far is
class 2nd_Controller extends 1st_Controller {
public function __construct()
{
header("Access-Control-Allow-Origin: *");
parent::__construct();
$this->load->model('2nd_model','2ndmodel');
$this->load->helper('url');
$this->load->library("pagination");
$this->load->library("session");
}
public function index()
{
$data['title'] = 'System Login';
$get_all_inv = $this->2ndmodel->get_all();
$data["tryvariable"] = $get_all_inv;
$this->template->load('default_layout','contents','myview2nd', $data);
}
}
I tried echo in my view like this
<?php echo $tryvariable; ?>
but no luck because the error says that it is an undefined variable .

Answer 1

Your second controller can't be define cause it's not define as subclass_prefix in your codeigniter application.
class 2nd_Controller extends 1st_Controller { //codeigniter don't recognize this.
}
The simpliest way to solve your problem is.. the fact that you can call multiple models in 1 Controller.
so you can have:
class 1st_Controller extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('1st_model','1stmodel');
$this->load->model('2nd_model','2ndmodel');
}
}
or call just once.
class 2nd_Controller extends CI_Controller {
public function __construct()
{
parent::__construct();
$this->load->model('2nd_model','2ndmodel');
}
}
Hope that helps.

So what I did was write like this on my route to have my 2nd_Controller working
$route['default_controller'] = '1st_Controller';
$route['404_override'] = '';
$route['translate_uri_dashes'] = FALSE;
$route['2nd_Controller'] = '2nd_Controller';
Now everything is working perfectly. Thanks for all the help
