POHow to save and extract session data in codeigniter
text
Body
copied!<p>I save some data in session on my verify controller then I extract this session data into user_activity model and insert session data into activity table. My problem is only username data saved in session and I can get and insert only username data after extracting session on model. I am new in Codeigniter. For this reason It’s very difficult to find out the problem. I am trying several days finding the problem. But unfortunately I can’t. So please, anyone help me. Thanks</p> <p>VerifyLogin controller:</p> <pre><code><?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 { $this->form_validation->set_message('check_database', 'Invalid username or password'); return false; } } } ?> </code></pre> <p>user_activity model:</p> <pre><code> <?php Class User_activity extends CI_Model { function activity() { if($this->session->userdata('logged_in')) { $session_data = $this->session->userdata('logged_in'); // $data['username'] = $session_data['username']; $data = array( 'session_id'=>"", 'ip_address'=>$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 = $_SERVER['HTTP_X_FORWARDED_FOR']; else if($_SERVER['HTTP_X_FORWARDED']) $ipaddress = $_SERVER['HTTP_X_FORWARDED']; else if($_SERVER['HTTP_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']; else $ipaddress = 'UNKNOWN'; return $ipaddress; } } } ?> </code></pre>
