我的users_model中有一个名为isLoggedin()的静态函数,它需要我创建的库。我无法加载它!它位于名为SessionsHelper.php的libraries文件夹中,并且里面有一个SessionsHelper类(我知道并不奇怪)。我尝试在$this->load->library('SessionsHelper')
的静态函数中加载它只是为了发现我不能在静态函数中使用$ this。然后我尝试使用require_once '../libraries/SessionsHelper.php'
加载它,这不起作用,然后我尝试了自动加载器,它也不起作用....所以这是函数。
public static function isLoggedin() {
if (SessionsHelper::get('id') != '' && SessionsHelper::get('id') >= 0) { // TODO add logic to differentiate between user/admin
return true;
}
return false;
}
我只需要能够使用该库!请任何帮助都非常感激!
编辑: 控制器是:
class Users extends CI_Controller{
public function login(){
$this->load->model('users_model');
if($this->users_model->isLoggedin()){
redirect($this->config->base_url);
}
$data['info'] = $this->users_model->login('slavigne@uark.edu', 'abcdefg');
$this->load->view('templates/header');
$this->load->view('users/login', $data);
$this->load->view('templates/footer');
}
public function logout(){
$this->load->library('SessionHelper');
SessionsHelper::destroy();
}
}
模型是:
class users_model extends CI_Model{
public function users_model(){
parent::__construct();
}
public static function hash($password, $salt) {
//this code works no problem! but it's private you know?
}
public static function isLoggedin() {
$CI =& get_instance();
$CI->load->library('SessionsHelper');
if (SessionsHelper::get('id') != '' && SessionsHelper::get('id') >= 0) { // TODO add logic to differentiate between user/admin
return true;
}
return false;
}
public function login($email, $password){
$this->load->library('SessionHelper');
$this->load->database();
$query = $this->db->get_where('users', array('email' => $email));
$result = $query->result();
if($result[0]->password == $this->hash($password, $result[0]->salt)){
//error_log("Pass matched!");
SessionHelper::set('id', $result[0]->id);
}
return $result[0];
}
}
库是,并且在application / libraries / Sessinshelper.php中:
class Sessionshelper {
public function __construct() {
}
public static function start() {
if (!session_id()) {
session_start();
}
}
public static function set($fld, $val) {
self::start();
$_SESSION[$fld] = $val;
}
public static function un_set($fld) {
self::start();
unset($_SESSION[$fld]);
}
public static function destroy() {
if (session_id() != "" || isset($_COOKIE[session_name()])) {
$params = session_get_cookie_params();
setcookie(session_name(), '', time() - 42000, $params["path"], $params["domain"], $params["secure"], $params["httponly"]);
}
session_unset();
$_SESSION = array();
session_destroy();
}
public static function get($fld) {
self::start();
if (isset($_SESSION[$fld])) {
return $_SESSION[$fld];
}
return FALSE;
}
}
答案 0 :(得分:1)
您可以通过使用get_instance
加载全局可访问的 CodeIgniter实例,在静态上下文中加载任何库,从而产生:
$CI =& get_instance();
$CI->load->library('SessionHelper');
但是静态方法通常被社区认为难以测试和设计气味,尤其是在使用像CodeIgniter这样的框架时可以避免它。
