这是我的模型课
class Sessions_model extends CI_Model
{
private $permission = array()
public function __construct()
{
parent::__construct();
}
public function is_login()
{
if($this->session->userdata('logged_in')) return TRUE;
else return false;
}
public function login($username,$password)
{
$this->db->where('username',$username);
$this->db->where('password',$password);
$query = $this->db->get('users');
if($query->num_rows()==1){
$user = $query->row();
$this->set_authnication($user->id);
return TRUE;
}
}
public function logout()
{
$this->session->sess_destroy();
}
public function set_authnication($user_id)
{
$this->load->helper('date');
$query = $this->db->where('id',$user_id)->get('users');
$user = $query->row();
$auth_data = array(
'user_id' => $user_id,
'logged_in' => 1,
'name' => $user->name,
'username'=> $user->username,
'email' => $user->email,
'role' => $this->initRole($user_id),
'lastVisitDate'=> now()
);
$this->session->set_userdata($auth_data);
}
public function initRole($id)
{
$role_perm = array();
$role = $this->db->where('id',$id)->get('roles')->row();
return $role_perm= array(
$role->description => $this->getPerm($role->id)
);
}
public function getPerm($id)
{
$perms = $this->db->where('role_id',$id)->get('permissions')->result();
foreach ($perms as $perm) {
$this->permissions[$perm->permission] = true;
}
return $this->permissions;
}
public function hasPermTo()
{
// $this->getPerm('1');
// return (isset($permissions[$perm]))? 'true' : 'false';
// print_r($this->session->userdata('role'));
print_r($this->permissions);
}
}
当我设置登录用户名和密码并调用 set_authnication($user_id) 时。当此登录方法完成时，我获得了具有权限的角色。我将我的私有属性设置为具有关联权限..到目前为止，一切似乎都还不错。已通过身份验证，我尝试验证该用户是否有权访问该类，因此我调用函数 $this->sessions_model->hasPermTo(); 但是这次我的私有属性是空数组（）..它有第n个......我不知道问题是什么？
