To use the get_instance() function in a custom library file in CodeIgniter, follow these steps:

  1. In your custom library file, first load the CodeIgniter instance by including the following line of code:


$CI =& get_instance();


This will store the CodeIgniter instance in the variable $CI for further use.

  1. You can now access CodeIgniter's resources and functions using the $CI variable. For example, you can load models, libraries, helpers, and use database functions like this:
1
2
3
4
$CI->load->model('Your_model');
$CI->load->library('Your_library');
$CI->load->helper('Your_helper');
$CI->db->query('Your SQL query');


  1. Remember to load the custom library in your controller before you can use it. You can load the library in the controller constructor or in any method where you want to use it:
1
$this->load->library('Your_custom_library');


By following these steps, you can use the get_instance() function in your custom library file in CodeIgniter and access CodeIgniter's resources and functions within the library.
