如果有人登录,这段代码会检查会话,我可以成功查看页面,但现在我想检查用户是否是管理员。我尝试通过以下方式检查模型,这是我尝试过的,但它不起作用。
检查会话以及是否为管理员的方法
public function index()
{
$this->load->library('authlib');
$loggedin = $this->authlib->is_loggedin();
///$admin = $this->auth->admin();
if ($loggedin === false) {
$this->load->helper('url');
redirect('/auth/login');
}
if ($this->auth->admin() === false) {
$message ['msg'] = "You are not an admin!";
$this->load->view('homeview', $message);
}
else
{
$this->load->view('add_view');
}
}
认证控制器
public function authenticate()
{
$username = $this->input->post('uname');
$password = $this->input->post('pword');
$user = $this->authlib->login($username,$password);
**>> $this->admin($username,$password); << passes the posted in values**
if ($user !== false) {
$this->load->view('homeview',array('name' => $user['name']));
}
else {
$data['errmsg'] = 'Unable to login - please try again';
$this->load->view('login_view',$data);
}
}
public function admin($username,$password){
//$this->load-model('usermodel');
$admin = $this->authlib->adminlib($username,$password);
if ($admin == false){
return false;
//if ($res->num_rows() != 1){
//return false;
}
}
库 authlib
public function adminlib($user,$pwd)
{
return $this->ci->usermodel->chkadmn($user,$pwd);
}
该模型
function chkadmn($username,$password)
{
$this->db-where(array('username' => $username,'password' => sha1($password)));
$res = $this->db->get('users',array('type'));
if ($res->num_rows() != 1) {
return false;
}
}
做了一些更改,现在我得到“在第 54 行调用 C:\xampp\htdocs\ecwm604\application\models\usermodel.php 中的未定义函数 where()”
