recall the construct in codigniter - codeigniter

Question

How to recall the construct as it contains all the required data for the page?
class Abc extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('xyz_m');
$this->data['info'] = $this->xyz_m->get(); //get data
}
public function 123()
{
/*view page code*/
}
public function 456()
{
/*insert code here*/
$this->123(); // redirect, need to load 123() with updated data from construct.
}
}
So, how do you make the __construct initiate again so you get a new updated results from database?

Answer 1

You should name your methods with letter first i.e. there is convention for method names uses descriptive words getProducts() or get_books or you will get PHP error for using numbers as method names. So in your case method names should be like a123() or b_456().
Second thing, regarding your need in question, since you assign data from DB using model to array $this->data, you would use it like:
class Abc extends CI_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('xyz_m');
$this->data['info'] = $this->xyz_m->get(); //get data
}
public function a123()
{
$this->load->view('a123_view', $this->data);//loading file APPPATH . 'a123_view.php' and passing created array to it
}
public function b_456()
{
/*insert code here*/
$this->a123(); // redirect, need to load 123() with updated data from construct.
}
}
In your APPPATH . 'a123_view.php':
<?php var_dump($info);//here you would call key of array you passed from controller as variable ?>
