How to access Magento from CodeIgniter? - codeigniter

Question

I have a default CodeIgniter 2.1 install with Magento 10.4.4 installed in a subdir called store.
The following code works when run from web root (with .htaccess disabled). It will give the firstname, lastname of the logged in Magento user.
<?php
$site_root = '/var/www/mysite/www/httpdocs';
require_once ($site_root . '/store/app/Mage.php');
umask(0);
// Initialize Magento and hide sensitive config data below site root
$name='frontend';
$options = array('etc_dir' => realpath('../magento-etc'));
Mage::app('default','store', $options);
Mage::getSingleton("core/session", array("name" => $name));
$websiteId = Mage::app()->getWebsite()->getId();
echo "websiteid: $websiteId<br>";
$store = Mage::app()->getStore();
$customer = Mage::getModel("customer/customer");
$customer->website_id = $websiteId;
$customer->setStore($store);
echo 'customerwebsiteId: ' . $customer->website_id . '<br>';
$session = Mage::getSingleton('customer/session');
$magento_message = 'Welcome ';
// Generate a personalize greeting
if($session->isLoggedIn()){
$magento_message .= $session->getCustomer()->getData('firstname').' ';
$magento_message .= $session->getCustomer()->getData('lastname').'!';
}else{
$magento_message .= 'Guest!';
}
echo $magento_message;
?>
But, if I run this in a CodeIgniter model, then isLoggedIn returns false.
Here is the CodeIgniter page:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Test_mage extends CI_Controller {
function __construct()
{
parent::__construct();
}
public function index()
{
$site_root = '/var/www/mysite/www/httpdocs';
require_once ($site_root . '/store/app/Mage.php');
umask(0);
// Initialize Magento and hide sensitive config data below site root
$name='frontend';
$options = array('etc_dir' => realpath('../magento-etc'));
Mage::app('default','store', $options);
Mage::getSingleton("core/session", array("name" => $name));
$websiteId = Mage::app()->getWebsite()->getId();
echo "websiteid: $websiteId<br>";
$store = Mage::app()->getStore();
$customer = Mage::getModel("customer/customer");
$customer->website_id = $websiteId;
$customer->setStore($store);
echo 'customerwebsiteId: ' . $customer->website_id . '<br>';
$session = Mage::getSingleton('customer/session');
$magento_message = 'Welcome ';
// Generate a personalize greeting
if($session->isLoggedIn()){
$magento_message .= $session->getCustomer()->getData('firstname').' ';
$magento_message .= $session->getCustomer()->getData('lastname').'!';
}else{
$magento_message .= 'Guest!';
}
echo $magento_message;
}
}
CodeIgniter is doing something that I have not been able to track yet. The websiteId is returned correctly, but isLoggedIn returns false.
Anyone have any ideas? THANKS!!

Answer 1

I use both but ive never tried to mash them like that. I foresee quite a few problems.
How are you patching into magento?
You might need two db connections running :
$db['magento']
$db['default'] // codeigniter default
Sessions could become a real problem here also aswell as config data.
Consider sticking with magento for now, then maybe patch into your blog/website via a RESTFul service.

Answer 2

Both code examples above work fine. The problem I had was calling session_start() near the top of the CodeIgniter index.php file. Once that was removed, it all started working.
For posterity, here is a Magento 10 Library for CodeIgniter 2.1:
application/libraries/magento.php
<?php if ( ! defined('BASEPATH')) exit("No direct script access allowed");
Class Magento {
function __construct($params)
{
global $site_root;
$name = $params['name'];
// Include Magento application
require_once ($site_root . '/store/app/Mage.php');
umask(0);
// Initialize Magento and hide sensitive config data below site root
// Uncomment next line if you have moved app/etc
// $options = array('etc_dir' => realpath('../magento-etc'));
Mage::app('default','store', $options=null);
return Mage::getSingleton("core/session", array("name" => $name));
}
}
// end of magento.php
Usage example app/model/test_mage.php
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Test_mage extends CI_Controller {
function __construct()
{
parent::__construct();
$params = array('name' => 'frontend'); // frontend or adminhtml
$this->load->library('magento', $params);
}
public function index()
{
$session = Mage::getSingleton('customer/session');
$magento_message = 'Welcome ';
// Generate a personalize greeting
if ($session->isLoggedIn())
{
$magento_message .= $session->getCustomer()->getData('firstname').' ';
$magento_message .= $session->getCustomer()->getData('lastname').'!';
}
else
$magento_message .= 'Guest!';
echo $magento_message . '<br>';
}
}
// end of test_mage.php
