当用户登录时，会话设置并显示正确的数据。但是当我点击“aboutview”，它有一个名为“aboutView（）”的函数时，会显示以前登录的用户数据。当我刷新页面时，它将显示当前登录用户的正确数据。
请检查并更正错误。
这是我的控制器（user.php）
<?php
class User extends CI_Controller
{
public function __construct()
{
parent::__construct();
session_cache_limiter('private_no_expire');
session_start();
$this->load->model('usermodel');
$this->load->helper(array('form', 'url', 'html', 'date'));
$this->load->library(array('session', 'javascript', 'form_validation', 'upload','email'));
$this->load->database();
$url = base_url() . 'user';
$this->smarty->assign('url', "$url");
}
public function loginValid()
{
$this->form_validation->set_rules('uname', 'Username', 'trim|required|min_length[3]');
$this->form_validation->set_rules('pswd', 'Password', 'trim|required');
if ($this->form_validation->run() == FALSE)
{
$this->smarty->display('user/login.tpl');
}
else
{
$this->load->model('usermodel');
$res = $this->usermodel->login();
if ($res == "success")
{
$dataArray = $this->usermodel->viewStatus();
$notificationCount = $this->usermodel->getNotification();
$decode = json_decode(json_encode($dataArray), TRUE);
$getCount = count(json_decode(json_encode($notificationCount),TRUE));
$getName = json_decode(json_encode($notificationCount),TRUE);
$this->smarty->assign('count', $getCount );
$this->smarty->assign('items', $decode);
$this->smarty->assign('name', $getName);
$this->smarty->assign('smsg', 'Login success');
$this->smarty->display('user/home.tpl');
}
else
{
$this->smarty->assign('msg', 'Invalid username and password');
$this->smarty->display('user/login.tpl');
}
}
}
public function aboutView()
{
$dataArray = $this->usermodel->aboutView();
$decode = json_decode(json_encode($dataArray),TRUE);
$this->smarty->assign('items', $decode);
$this->smarty->display('user/aboutview.tpl');
}
这是我的模型“usermodel.php”
<?php
class Usermodel extends CI_Model
{
public function __construct()
{
parent::__construct();
}
public function login()
{
$username = $this->input->post('username');
$pswd = $this->input->post('pswd');
$this->db->select('username,userID');
$data = $this->db->get_where('users', array('userName' => $username, 'password' => $pswd))->row_array();
if ($data)
{
$this->session->set_userdata($data);
return "success";
}
else
return "fail";
}
public function aboutView()
{
$id = $this->session->userdata('userID');
$this->db->select('*');
$this->db->from('users');
$this->db->where('userID', $id);
$query = $this->db->get();
return $query->result();
}
这是我的观点“aboutview.tpl”
