如何在代码点火器框架中定义动态全局变量。

Question

How to define a dynamic global variable in code-igniter framework.

I am using Geo-Location tracking api, which tracks the country of the user based on user's IP address. I need to set the value of this global variable dynamically depending on the country code returned from the API.

what is the best way to achieve this ?

Answer 1

In your case, You can store the value in session like this

$newdata = array(
               'country'  => 'Nepal',
           );

$this->session->set_userdata($newdata);

And again retrieve the session value like this

$country = $this->session->userdata('country');
