回答1:
It seems you are not loading your "site model" anywhere in code you can do following:
- autoload it in autoload file.
- load your model either in constructor of controller, or load it whenever needed by using this line
$this->load->model('site_model');
More information can be found here.
回答2:
You need to load model in your controller.
class Site extends CI_Controller{
function __construct(){
parent::__construct();
$this->is_logged_in();
$this->load->model('site_model'); //Load site_model
........
回答3:
In somecase it happens when you don't extract your form data to the model. Try extract($_POST) in your model and don't forget to load the model properly.
P.s.:this was the solution for my error
