public function __construct()
{
parent::__construct();
$this->db = $this->load->database('default', true);
}
public function add2()
{
$this->load->model('Agentie_model',true);
$data['principal'] = $this->Agentie_model->get_agentii_list(); //Here
$this->load->view('lista_agentii', $data);
}

Answer 2

in your controller set this below
function fk_controller() {
parent::__construct();
$this->load->model('agentie_model');
$this->load->model('fk_model');
}
public function add2() {
$this->load->model('agentie_model');
$data['principal'] = $this->agentie_model->get_agentii_list(); //Here is the error(line 65)
$this->load->view('lista_agentii', $data);
}
in your model view
class Agentie_model extends CI_Model
{
public function get_agentii_list() {
$query = $this->db->get($this->_table);
return $query->result();
}
}
