Codeigniter session in wordpress

问题:

I have developed a website in codeigniter and integrated wordpress for blog. My problem is if i logged in the site, i am not able to use the codeigniter session value in the wordpress blog.

In Codeigniter once i logged in i am setting the following session using codeigniter session.

$this->session->set_userdata('get_user_session', $auD);

Now i need to use the session in wordpress header file or index file. I tried the below code in wordpress.

session_start();
print_r($_SESSION);

I am not getting the above ci session values.

CodeIgniter's Session class:

>> stores session information for each user as serialized (and optionally encrypted) data in a cookie.

The values you set using $this->session->set_userdata('key','value') are not going to be present in the $_SESSION variable.

CodeIgniter also supports storing session content in a database.

You can use that configuration to retrieve the session data in your WordPress blog.

Use COOKIES to get the session data. Refer this link: https://thomashunter.name/blog/accessing-codeigniter-session-data-using-external-scripts/

require_once("config.php");
$cisess_cookie = $_COOKIE['ci_session'];
$cisess_cookie = stripslashes($cisess_cookie);
$cisess_cookie = unserialize($cisess_cookie);
$cisess_session_id = $cisess_cookie['session_id'];

$cisess_connect = mysql_connect(MYSQL_HOSTNAME, MYSQL_USERNAME, MYSQL_PASSWORD);
if (!$cisess_connect) {
 die("<div class="error">" . mysql_error() . "</div>");
}
$cisess_query = "SELECT user_data FROM ci_sessions WHERE session_id = '$cisess_session_id' LIMIT 1";

mysql_select_db(MYSQL_DATABASE, $cisess_connect);
$cisess_result = mysql_query($cisess_query, $cisess_connect);
if (!$cisess_result) {
 die("Invalid Query");
}
$cisess_row = mysql_fetch_assoc($cisess_result);
$cisess_data = unserialize($cisess_row['user_data']);
print_r($cisess_data);
