Opencart session info in Wordpress - wordpress

Question

I have a site that is using both WordPress and Opencart. The main site is built off of WP and then there is an OC site in a sub-directory.
I would like to bring the session data from OC into the wordpress site so I can have the Wishlist, Shopping Cart, Checkout, Login status and My Account info throughout the site.
Does anyone know what code I can add to WP to bring in this info?
Thanks again in advance,
Matt

Answer 1

There are already many articles regarding module development and export and session building in OpenCart.
Given your existing pages:
yoursite.com/wordpress
yoursite.com/wordpress/page.php (i.e. your page outside the shop),
yoursite.com/products/catalog/controller/common/header.php -and-
yoursite/products/catalog/view/theme/default/template/common/header.tpl
1. Create file headerXYZ.php using the following code and save it to the root directory of your main site (or other location of your choosing outside your OC shop).
<?php
// Config
require_once('shop/config.php');
// VirtualQMOD
require_once('shop/vqmod/vqmod.php');
$vqmod = new VQMod();
// VQMODDED Startup
require_once($vqmod->modCheck(DIR_SYSTEM . 'startup.php'));
// Application Classes
require_once($vqmod->modCheck(DIR_SYSTEM . 'library/customer.php'));
require_once($vqmod->modCheck(DIR_SYSTEM . 'library/affiliate.php'));
require_once($vqmod->modCheck(DIR_SYSTEM . 'library/currency.php'));
require_once($vqmod->modCheck(DIR_SYSTEM . 'library/tax.php'));
require_once($vqmod->modCheck(DIR_SYSTEM . 'library/weight.php'));
require_once($vqmod->modCheck(DIR_SYSTEM . 'library/length.php'));
require_once($vqmod->modCheck(DIR_SYSTEM . 'library/cart.php'));
$myVar = array();
$myVar = array();
// Registry
$registry = new Registry();
// Loader
$loader = new Loader($registry);
$registry->set('load', $loader);
// Config
$config = new Config();
$registry->set('config', $config);
// Database
$db = new DB(DB_DRIVER, DB_HOSTNAME, DB_USERNAME, DB_PASSWORD, DB_DATABASE);
$registry->set('db', $db);
// Url
$url = new Url($config->get('config_url'), $config->get('config_use_ssl') ? $config->get('config_ssl') :
$config->get('config_url'));
$registry->set('url', $url);
// Log
$log = new Log($config->get('config_error_filename'));
$registry->set('log', $log);
function error_handler($errno, $errstr, $errfile, $errline) {
global $log, $config;
switch ($errno) {
case E_NOTICE:
case E_USER_NOTICE:
$error = 'Notice';
break;

$error = 'Warning';

$error = 'Fatal Error';
break;

$error = 'Unknown';
break;
}
if ($config->get('config_error_display')) {
echo '<b>' . $error . '</b>: ' . $errstr . ' in <b>' . $errfile . '</b> on line <b>' . $errline . '</b>';
}
if ($config->get('config_error_log')) {

} elseif (isset($session->data['language']) && array_key_exists($session->data['language'], $languages)) {

} elseif (isset($request->cookie['language']) && array_key_exists($request->cookie['language'], $languages)) {

} elseif ($detect) {

} else {

}
if (!isset($session->data['language']) || $session->data['language'] != $code) {
$session->data['language'] = $code;
}
if (!isset($request->cookie['language']) || $request->cookie['language'] != $code) {
setcookie('language', $code, time() + 60 * 60 * 24 * 30, '/', $request->server['HTTP_HOST']);
}
$config->set('config_language_id', $languages[$code]['language_id']);
$config->set('config_language', $languages[$code]['code']);
// Language
$language = new Language($languages[$code]['directory']);
$language->load($languages[$code]['filename']);
$registry->set('language', $language);
// Document

$registry->set('customer', new Customer($registry));

$affiliate = new Affiliate($registry);
$registry->set('affiliate', $affiliate);
if (isset($request->get['tracking']) && !isset($request->cookie['tracking'])) {
setcookie('tracking', $request->get['tracking'], time() + 3600 * 24 * 1000, '/');
}
// Currency
$registry->set('currency', new Currency($registry));
// Tax
$tax = new Tax($registry);
$registry->set('tax', $tax);
// Weight
$registry->set('weight', new Weight($registry));
// Length
$registry->set('length', new Length($registry));
// Cart
$registry->set('cart', new Cart($registry));
// Front Controller
$controller = new Front($registry);
// Maintenance Mode
$controller->addPreAction(new Action('common/maintenance'));
// SEO URL's
$controller->addPreAction(new Action('common/seo_url'));
// Router
if (isset($request->get['route'])) {
$action = new Action($request->get['route']);
} else {
$action = new Action('common/home');
}
// Dispatch
$controller->dispatch($action, new Action('error/not_found'));
2. Now, include headerXYZ.php in page.php i.e. Place the statement below on line 1 at the very top of page.php
<?php require_once ('headerXYZ.php');?>
3. Finally, right after the opening body tag of your external page.php page add the following list of statements
<?php
require_once('shop/catalog/model/total/sub_total.php');
require_once('shop/catalog/language/english/total/sub_total.php');
require_once('shop/catalog/model/total/reward.php');
require_once('shop/catalog/model/total/shipping.php');
require_once('shop/catalog/model/total/coupon.php');
require_once('shop/catalog/model/total/tax.php');
require_once('shop/catalog/model/total/credit.php');
require_once('shop/catalog/language/english/total/credit.php');
require_once('shop/catalog/model/total/voucher.php');
require_once('shop/catalog/model/total/total.php');
require_once('shop/catalog/language/english/total/total.php');
foreach($myVar as $key=>$value)
{
$$key = $value;
}
require_once('shop/catalog/controller/common/header.php');
require_once('shop/catalog/view/theme/default/template/common/header.tpl');
?>
That's it... You're done! You should now have a fully functional header (with working cart, login, etc.) in your page located outside of your Opencart shop.
SIDE NOTE: You could also just plug the entire code (including the content of headerXYZ.php and the 13 require_once statements) directly into the your external page.

Answer 2

I was looking for something similar, what I did was to write same html/css for footer and header in both systems, after that, I wrote an additional Wordpress plugin to show user and cart info when user is logged in opencart.
