我在验证控制器上的会话中保存了一些数据,然后我将此会话数据提取到user_activity模型中,并将会话数据插入到活动表中。我的问题是只保存在会话中的用户名数据,我可以在模型上提取会话后获取并仅插入用户名数据。我是Codeigniter的新手。因此,找出问题非常困难。我想好几天才发现问题。但不幸的是我做不到。所以,请任何人帮助我。感谢
VerifyLogin控制器:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
session_start();
class VerifyLogin extends CI_Controller {
function __construct()
{
parent::__construct();
$this->load->model('user','',TRUE);
$this->load->model('user_activity','',TRUE);
}
function index()
{
//This method will have the credentials validation
$this->load->library('form_validation');
$this->form_validation->set_rules('username', 'Username', 'trim|required|xss_clean');
$this->form_validation->set_rules('password', 'Password', 'trim|required|xss_clean|callback_check_database');
if($this->form_validation->run() == FALSE)
{
//Field validation failed. User redirected to login page
$this->load->view('login_view');
}
else
{
//Go to private area
redirect('home', 'refresh');
}
}
function check_database($password)
{
//Field validation succeeded. Validate against database
$username = $this->input->post('username');
$vercode = $this->input->post('vercode');
//query the database
$result = $this->user->login($username, $password);
// ip address
$ip_address= $this->user_activity->get_client_ip();
//Retrieving session data and other data
$captcha_code=$_SESSION['captcha'];
$user_agent=$_SERVER['HTTP_USER_AGENT'];
if($result && $captcha_code == $vercode)
{
$sess_array = array();
foreach($result as $row)
{
$sess_array = array(
'username' => $row->username,
'user_agent' => $row->user_agent,
'ip_address' => $row->ip_address,
);
$this->session->set_userdata('logged_in', $sess_array);
//insert user activity
$this->user_activity->activity();
}
return TRUE;
}
else
{
$this->form_validation->set_message('check_database', 'Invalid username or password');
return false;
}
}
}
?>
user_activity模型:
<?php
Class User_activity extends CI_Model
{
function activity()
{
if($this->session->userdata('logged_in'))
{
$session_data = $this->session->userdata('logged_in');
// $data['username'] = $session_data['username'];

'session_id'=>"",
'ip_address'=>$session_data['ip_address'],
'user_agent'=>$session_data['user_agent'],
'username'=>$session_data['username'],
'time_stmp'=>Now(),
'user_data'=>$session_data['username']."Logged in Account"
);
$this->db->insert('user_activity',$data);
}
else
{
return false;
}
// Function to get the client ip address
function get_client_ip() {
$ipaddress = '';
if ($_SERVER['HTTP_CLIENT_IP'])
$ipaddress = $_SERVER['HTTP_CLIENT_IP'];
else if($_SERVER['HTTP_X_FORWARDED_FOR'])
$ipaddress = $_SERVER['HTTP_X_FORWARDED_FOR'];

$ipaddress = $_SERVER['HTTP_FORWARDED_FOR'];
else if($_SERVER['HTTP_FORWARDED'])
$ipaddress = $_SERVER['HTTP_FORWARDED'];
else if($_SERVER['REMOTE_ADDR'])
$ipaddress = $_SERVER['REMOTE_ADDR'];

return $ipaddress;
}

您可以在Codeigniter中将数据设置为会话,如下所示:
$this->load->library('session');
$this->session->set_userdata(array(
'user_id' => $user->uid,
'username' => $user->username,
'groupid' => $user->groupid,
'date' => $user->date_cr,
'serial' => $user->serial,
'rec_id' => $user->rec_id,
'status' => TRUE
));
你可以这样得到它:
$u_rec_id = $this->session->userdata('rec_id');
$serial = $this->session->userdata('serial');

首先你有加载会话库。
$this->load->library("session");
您可以在自动加载中加载它,我认为这是更好的。
设置会话
$this->session->set_userdata("SESSION_NAME","VALUE");
提取数据
$this->session->userdata("SESSION_NAME");

使用
初始化控制器构造函数中的Session类$this->load->library('session');
例如:
function __construct()
{
parent::__construct();
$this->load->model('user','',TRUE);
$this->load->model('user_activity','',TRUE);
$this->load->library('session');
}

在codeigniter中,我们能够将会话值存储在数据库中。
在config.php文件中,生成sess_use_database变量true
$config['sess_use_database'] = TRUE;
$config['sess_table_name'] = 'ci_sessions';
并在数据库中创建一个ci_session表
CREATE TABLE IF NOT EXISTS `ci_sessions` (
session_id varchar(40) DEFAULT '0' NOT NULL,
ip_address varchar(45) DEFAULT '0' NOT NULL,
user_agent varchar(120) NOT NULL,
last_activity int(10) unsigned DEFAULT 0 NOT NULL,
user_data text NOT NULL,
PRIMARY KEY (session_id),
KEY `last_activity_idx` (`last_activity`)
);

CI会话类跟踪每个用户浏览site.Ci会话类时生成自己的会话数据,为开发人员提供更多灵活性。
初始化会话
要在我们的控制器构造函数中手动初始化Session类,请使用以下代码。
添加自定义会话数据
我们可以在会话数组中添加自定义数据。要将数据添加到会话数组,需要将包含新数据的数组传递给此函数。
$this->session->set_userdata($newarray);
$ newarray是一个包含我们新数据的关联数组。
$newarray = array( 'name' => 'manish', 'email' => 'manish@our-site.com'); $this->session->set_userdata($newarray);
检索会话
$ session_id = $ this-&gt; session-&gt; userdata(&#39; session_id&#39;);
如果会话数组不存在,则上面的函数返回FALSE(布尔值)。
检索所有会话数据
$这 - &GT;会话而&GT; all_userdata()

在CodeIgniter中,您可以将会话值存储为单个或以数组格式存储,如下所示:
如果你想在会话中存储任何用户的数据,如userId,userName,userContact等,那么你应该存储在数组中:
<?php
$this->load->library('session');
$this->session->set_userdata(array(
'userId' => $user->userId,
'userName' => $user->userName,
'userContact ' => $user->userContact
));
?>
