To deal with CSRF security in CodeIgniter, you can follow these steps:

  1. Enable CSRF protection in the config.php file: In your CodeIgniter project, open the config.php file located in the application/config folder. Set the value of $config['csrf_protection'] to TRUE to enable CSRF protection.
  2. Generate CSRF tokens in your forms: In your forms, add a hidden input field with the name "csrf_test_name" and set its value to the CSRF token generated using the form_open() function in CodeIgniter.
  3. Validate the CSRF token in your controller: In your controller, use the $this->security->csrf_verify() method to validate the CSRF token. If the token is invalid, you can show an error message or redirect the user to a different page.
  4. Use CSRF tokens in AJAX requests: If you're making AJAX requests in your CodeIgniter application, make sure to include the CSRF token in the request data. You can generate the token using the $this->security->get_csrf_hash() method and include it in the request headers.


By following these steps, you can effectively deal with CSRF security in your CodeIgniter application and protect it from CSRF attacks.
