Answer 1

Codeigniter has inbuilt function to check if the request is made using Ajax call.

You can use the following way to validate if a controller/segment is called using Ajax or not.

input->is_ajax_request()){
       show_404();
     }

  }

}

You can use many other checks as well using input class. Few of them are

• $this->input->get_request_header();
• $this->input->is_cli_request()
• $this->input->ip_address()

You can view complete list of available methods at Official documentation
