First you have load session library     this- gt load- gt library  session      You can load it in auto load  which I think is better    To set session   this- gt session- gt set userdata  SESSION NAME   VALUE      To extract Data   this- gt session- gt userdata  SESSION NAME

In codeigniter we are able to store session values in a database  In the config php file make the sess use database variable true   config  sess use database     TRUE   config  sess table name      ci sessions     and create a ci session table in the database  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        For more details and reference  click here

CI Session Class track information about each user while they browse site Ci Session class generates its own session data  offering more flexibility for developers    Initializing a Session  To initialize the Session class manually in our controller constructor use following code   Adding Custom Session Data  We can add our custom data in session array To add our data to the session array involves passing an array containing your new data to this function    this- gt session- gt set userdata  newarray     Where  newarray is an associative array containing our new data    newarray   array   name    gt   manish    email    gt   manish our-site com     this- gt session- gt set userdata  newarray      Retrieving Session    session id    this- session- userdata  session id     Above function returns FALSE  boolean  if the session array does not exist   Retrieving All Session Data   this- session- all userdata    I have taken reference from http   www tutsway com codeigniter-session php

You can set data to session simply like this in Codeigniter    this- gt load- gt library  session     this- gt session- gt set userdata array       user id     gt   user- gt uid       username    gt   user- gt username       groupid     gt   user- gt groupid       date        gt   user- gt date cr       serial      gt   user- gt serial       rec id      gt   user- gt rec id       status      gt  TRUE       and you can get it like this    u rec id    this- gt session- gt userdata  rec id     serial    this- gt session- gt userdata  serial
