model_user :
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Model_user extends CI_Model {
function __construct() {
parent::__construct();
$this->tbl = "tabel_user";
}
function cek_user($username="",$password="") {
$query = $this->db->get_where($this->tbl,array('username' => $username, 'password' => $password));
$query = $query->result_array();
return $query;
}
function ambil_user($username)
{
$query = $this->db->get_where($this->tbl, array('username' => $username));
$query = $query->result_array();
if($query){
return $query[0];
}
}
function ambil_iduser($idUser)

if($query){
return $query[0];
}
}
function getAllUser() {
$this->db->from('tabel_user');
return $this->db->get();
}
function deleteUser($id)
{
$this->db->where('id_user', $id);
$this->db->delete('tabel_user');
}
}
?>
Jawaban_model:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Jawaban_model extends Ci_Model {
public function Ambil() {
$data = $this->db->query('select * from tabel_jawaban, tabel_user where tabel_jawaban.id_user=tabel_user.id_user');
return $data;
}
public function AmbilNilai2($iduser) {
$data = $this->db->query("select * from tabel_jawaban, tabel_user where tabel_jawaban.id_user=tabel_user.id_user AND tabel_jawaban.id_user='$iduser'");
return $data;
}
public function Simpan($tabel, $data){
$res = $this->db->insert($tabel, $data);
return $res;
}
public function UpdateTotalNilai($id_jawaban,$data)
{
$this->db->where('id_jawaban',$id_jawaban);
$this->db->update('tabel_jawaban',$data);

}
Controller :
function daftar(){
$ambil_akun = $this->session->userdata('uname');
$idUser = $this->user_model->AmbilIdUser($ambil_akun);
$data = array(
'id_user' => $idUser,
'tgl_tes' => date("Y-m-d"),
);
$this->jawaban_model->Simpan('tabel_jawaban', $data);
$id=mysql_insert_id();
redirect('dashboard/soaluser/'.$id);
}

Answer 1

There is minor typo in your code. As far as I could notice, your user_model-> method is
function ambil_iduser($idUser)
{
$query = $this->db->get_where($this->tbl, array('id_user' => $idUser));
$query = $query->result_array();
if($query){
return $query[0];
}
Whereas, in your controller, you are calling for different method here,
$idUser = $this->user_model->AmbilIdUser($ambil_akun);
Both the method's name differs ambil_iduser and AmbilIdUser.
The correct controller calling state should be
function daftar(){
$ambil_akun = $this->session->userdata('uname');
$idUser = $this->user_model->ambil_iduser($ambil_akun);
$data = array(
'id_user' => $idUser,
'tgl_tes' => date("Y-m-d"),
...
