How to get site language code on CodeIgniter?

Question

CodeIgniter

I am new to CodeIgniter.
Here is a demo that I 'm picking www.datingsoftware.ru/dating/demo.php
The site is multilingual (languages ​​are added from the admin panel).
How can I get the value of the language selected by the user anywhere in the code?
Next, in PHP I will write the conditions for displaying something, depending on the selected language.

Answer 1

Try saving cookies with the user's language selected, and then process them.

Answer 2

Sessions, cookies
For example, sessions:

// загружаем библиотеку там, где надо или добавляем ее в autoload.php
$this->load->library('session');

// устанавливаем значение
$this->session->set_userdata('language', 'ru');

// получаем значение
$this->session->userdata('language');
