ここに私の最初の質問があります。私はPHPとCIの初心者ですが、学びたいです:)
最初に私のモデル:
class Login_model extends MY_Model {
protected $table = 'users'; protected $primary = 'user_id'; function __construct() { parent::__construct(); } public function validate() { // Récupère le POST du login $user_mail = $this->input->post('user_mail'); $password = sha1($this->input->post('user_mail') . $this->input->post('password')); //Execution de la requete $query = $this->users_m->get(array('user_mail' => $user_mail)); // Verification qu'il existe un enregistrement var_dump($query); if($query->num_rows() == 1) { // If there is a user, then create session data $row = $query->row(); $data = array( 'userid' => $row->userid, 'fname' => $row->fname, 'lname' => $row->lname, 'username' => $row->username, 'validated' => true ); $this->session->set_userdata($data); return true; // } // Si le login ne se valide pas // return false. return false; } } }
このモデルはMy_modelMY_MODEL.PHPを拡張します

私は私のコントローラーを持っています:Accueil(デフォルトルートになります)
login()メソッドはviewlogin.phpを呼び出します
ACCUEIL.PHP:
<?php
if (!defined('BASEPATH'))
exit('No direct script access allowed');
class Accueil extends MY_Controller
{
public function __construct()
{
parent::__construct();
$this->load->model('users_model', 'users_m');
$this->load->library('form_validation');
$this->load->helper(array('form', 'url'));
$this->load->library('template');
}
public function index($msg = NULL) //msg en cas d'erreur , NULL si pas d'erreur
{
$data['msg'] = $msg;
$this->load->view('/login', $data);
}
public function login()
{
// Chargement du model de login
$this->load->model('login_model');
// Validation que l'user puisse se connecter
$result = $this->login_model->validate();
// Verification du résultat
if (!$result)
{
// Pas de validation on renvoit vers l'index
$msg = '<font color=red>Nom d\'utilisateur ou mot de passe incorrect(s).</font><br />';
$this->index($msg);
}
else
{
// Si validation ok,
// On l'envoit vers la partie "protégée"
redirect('home');
}
}
}

num_rows()で、未定義のメソッドであるというエラーが発生します...理由がわかりません。
ご不明な点がございましたら、お問い合わせください(英語はごめんなさい^^)
