Session expired after refresh using Codeigniter
<p>I'm trying to save my session, it expired after refreshing the page.</p>

<p>In my controller:</p>

<pre><code> if($u_id){
                $data=  array(
                    'id'=&gt;$u_id['id'],
                    'user_name'=&gt;$u_id['user_name'],
                    'password'=&gt;$password,

                );

                $this-&gt;session-&gt;set_userdata('logged_in',$data);
                $this-&gt;session-&gt;set_flashdata('login_succeed','Logged in Successfully');
                redirect('home/homepage');
            }
</code></pre>

<p>And in my homepage view:</p>

<pre><code>if (isset($this-&gt;session-&gt;userdata['logged_in'])){
                        echo $this-&gt;session-&gt;userdata['logged_in']['user_name'];}
</code></pre>

<p>My config:</p>

<pre><code>$config['sess_driver'] = 'files';
$config['sess_cookie_name'] = 'ci_session';
$config['sess_expiration'] = 7200;
$config['sess_save_path'] = NULL;
$config['sess_match_ip'] = FALSE;
$config['sess_time_to_update'] = 300;
$config['sess_regenerate_destroy'] = FALSE;
</code></pre>

<p>First time when redirect me to homepage, the session is correct and it gave me the username perfectly, but when I refresh the page, the session expired and redirect me to login page. Should I do something in construct or what can I do? please help! I'm using codeigniter</p>
