I based my solution on code found here
http://forum.joomla.org/viewtopic.php?f=304&t=580193.
At first I tried to load the Joomla framework within a CI library, but this caused a series of errors, and seemed like more trouble than it was worth.
My current working solution is to use CURL to access a custom script. I'm sure this could be refined further but I needed a quick solution.
JOOMLA SIDE (loads Joomla framework and returns logged in user object as JSON)
file: get_joomla_user.php (could be in the site root or anywhere as long as paths are correct)
Code:
<?php
define ( '_JEXEC', 1 );
define ( 'JPATH_BASE', $_SERVER ['DOCUMENT_ROOT'] . '/JOOMLA_ROOT/' );
define ( 'DS', DIRECTORY_SEPARATOR );
require_once (JPATH_BASE . DS . 'includes' . DS . 'defines.php');
require_once (JPATH_BASE . DS . 'includes' . DS . 'framework.php');
$mainframe = & JFactory::getApplication ( 'site' );
$mainframe->initialise ();
//I am using Jomsocal, so these are required to retrieve Jomsocial user object
require_once ( JPATH_ROOT.DS.'components'.DS.'com_community'.DS.'defines.community.php');
require_once (COMMUNITY_COM_PATH.DS.'libraries'.DS.'apps.php' );
//$user = JFactory::getUser (); //Joomla user object
$user = CFactory::getUser (); //Jomsocial user object
if ($user->id == 0) //user is not logged in
{
echo 'false';
} else {
echo json_encode($user); //return the user object as JSON object
}
CI SIDE - fetch user object via file_get_contents
file: CI_APP_FOLDER/libraries/Joomla_user.php
Code:
<?php
if (! defined ( 'BASEPATH' ))
exit ( 'No direct script access allowed' );
class Joomla_user {
var $CI; //create CI instance so we can access libraries
var $get_user_url = 'http://URL_TO_get_joomla_user.php';
function __construct() {
$this->CI = & get_instance ();
}
function get_user() {
//Need to set cookie context so that Joomla can access it's session/user cookie
$opts = array ('http' => array ('header' => 'Cookie: ' . $_SERVER ['HTTP_COOKIE'] . "\r\n" ) );
$context = stream_context_create ( $opts );
$juser = json_decode ( file_get_contents ( $this->get_user_url, false, $context ) );
if(!$juser){
//Not logged in - echo error -or-
//redirect to joomla login page
$this->CI->load->helper('url');
redirect('JOOMLA_LOGIN_PAGE_URL', 'refresh');
}else{
//Logged in
return $juser;
}
}
}
I hope this helps.
