Answer 1

in jquery you can do this:

$.ajax({
  type: "POST",
  url: 'test.php',
  data: '{"var":"yourvar"}',
  success: function (data) {
    console.log("Success!!");
  },
  error: function (xhr, desc, err) {
    console.log('error');
  }
});

and after into your file test.php

<?php  $this->session->set_userdata('friend_id' ,$_POST['var'] )?>
