Question

我想获取当前会话ID以在所有页面中使用它。我想在标头中传递会话数据。我可以将我的会话存储在ci_sessions表中。但是，如何从ci_sessions检索当前登录用户名/ sesson_id。

这是我的ci_sessions代码。

CREATE TABLE IF NOT EXISTS `ci_sessions` (
        `id` varchar(128) NOT NULL,
        `ip_address` varchar(45) NOT NULL,
        `timestamp` int(10) unsigned DEFAULT 0 NOT NULL,
        `data` blob NOT NULL,
        KEY `ci_sessions_timestamp` (`timestamp`)
);

这是会话设置代码

if($this->form_validation->run())
            {
                $username =  $this->input->post('login_username');
                $password =  $this->input->post('login_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'];

                //call the model for auth
                $this->load->Model('Auth_model');
                if($this->Auth_model->login($username, $password)){


                    $data = array(
                            'client_username' => $username,
                            'is_logged_in' => true
                              );                    

                    $this->session->set_userdata($data);
                    $this->load->view('include/header', $data);
                    //$this->session->set_flashdata('item', $datav['name']);

                }
                else{
                    echo'something went wrong';
                }

我正在使用pop dailog登录和注册，所以这是我的ajax。

<script>
    $("input#login_btn").on('click',function(event){
        event.preventDefault();

            var x = document.forms["loginform"]["login_username"].value;
            var x1 = document.forms["loginform"]["login_password"].value;
            var y = document.getElementById('login-error');
            var z = document.getElementById('password-error');

            if (x == "") { y.style.display ='block'; }else{ y.style.display ='none'; }
            if (x1 == "") { z.style.display ='block'; }else{ z.style.display ='none'; } 

                var d = document.forms["loginform"]["login_username"].value;
                var d1 = document.forms["loginform"]["login_password"].value;       

        if(d != '' && d1 != ''){
                var url = $(this).attr('action');
                var method = $(this).attr('method');
                var data = $(this).serialize();

                $.ajax({
                   url:url,
                   type:method,
                   data:data
                }).done(function(data){
                   if(data !=='')
                    {

                        if(d !== '' && d1 != '' ){
                            //$("#login_fail").show('fast');
                            //$("#login_fail").effect( "shake" );
                            $('#loginform')[0].reset();
                            //var url = $('#current_loginurl').val();                   
                            //window.location.href=url;

                            var url = $('#current_loginurl').val();                 
                            window.location.href=url;

                        }                       
                    }
                    else
                    {
                        var url = $('#current_loginurl').val();                 
                        window.location.href=url;
                        throw new Error('go');
                    } 
                });            

            $( "div" ).each(function( index ) {
            var cl = $(this).attr('class');
            if(cl =='')
                {
                    $(this).hide();
                }
            });
            }
        });
</script>

从下面的表格中查找current session。获取order by订单descending中的记录limit ID。

$this->db->order_by('id', 'DESC');
$this->db->limit(1);
$last_session = $this->db->get('ci_sessions')->row_array();

print_r($last_session['data']);//prints current session data

<强>更新但获取当前用户session id的最简单方法是使用session库。就像这样..

$this->load->library('session');
$id = $this->session->userdata('id');//id is session variable that you set
echo $id;

如何从ci_sessions中检索当前用户会话ID。
