session ne regestant pas la variable 3

Question

J'ai créé un système de connexion dans codeigniter. Cela fonctionne bien, mais quand je me connecte, il enregistre seulement 2 variables qui sont le login et le mot de passe mais ne me montre pas la 3ème variable de la session qui est user_type. J'ai trop essayé mais je n'arrive pas à comprendre ce qui ne va pas.

code modèle

function login($username, $password) { 
    //create query to connect user login database 
    $this->db->select('user_id, username, password','user_type'); 
    $this->db->from('login'); 
    $this->db->where('username', $username); 
    $this->db->where('password', $password); 
    $this->db->where('status',1); 
    $this->db->limit(1); 

    //get query and processing 
echo $query = $this->db->get(); 
    if($query->num_rows() == 1) { 
     return $query->result(); //if data is true 
    } else { 
     return false; //if data is wrong 
    } 
}

    $username = $this->input->post('username'); 
    //query the database

     $sess_array = array(); 
     foreach($result as $row) { 
      //create the session 
      $sess_array = array('user_id' => $row->user_id, 
       'username' => $row->username, 
       'user_type'=> $row->user_type 
       ); 
      //set session with value from database 
      $this->session->set_userdata('logged_in', $sess_array);

Answer 1

Parce que vous ne choisissez pas user_type dans votre requête de sélection.

Modifier ceci:

$this->db->select('user_id, username, password','user_type'); 

Avec ceci:

$this->db->select('user_id, username, password,user_type');
