• 1 you cannot insert into a var php a var javascript/jquery, PHP is server side javascript/jquery is clienti side – Alessandro Minoccheri Commented Mar 12, 2013 at 13:14

• You cannot pass a jQuery/javascript variable to PHP. PHP is run on the server before transmitting, jQuery/javascript is run client side. You should look into AJAX as the solution to your problem. – Jacob Tomlinson Commented Mar 12, 2013 at 13:15

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'] )?>

MANUAL

You can use hidden field to do this

      <input type="hidden" value="" name="id" id="id" />

this will in your js

      var a = 22;
      document.getElementById('id').value = a;

hope this will help you to solve your problem, but you can't set session in Jquery
