Opencart session info in 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

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.

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;
      case E_WARNING:
      case E_USER_WARNING:
         $error = 'Warning';
         break;
      case E_ERROR:
      case E_USER_ERROR:
         $error = 'Fatal Error';
         break;
      default:
         $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')) {
      $log->write('PHP ' . $error . ':  ' . $errstr . ' in ' . $errfile . ' on line ' . $errline);
   }

   return true;
}

// Error Handler
set_error_handler('error_handler');

// Request
$request = new Request();
$registry->set('request', $request);

$response->addHeader('Content-Type: text/html; charset=utf-8');

$query = $db->query("SELECT * FROM " . DB_PREFIX . "language");

foreach ($query->rows as $result) {
   $languages[$result['code']] = $result;
}

$detect = '';

if (isset($request->server['HTTP_ACCEPT_LANGUAGE']) && ($request->server['HTTP_ACCEPT_LANGUAGE'])) {
   $browser_languages = explode(',', $request->server['HTTP_ACCEPT_LANGUAGE']);

   foreach ($browser_languages as $browser_language) {
      foreach ($languages as $key => $value) {
         if ($value['status']) {
            $locale = explode(',', $value['locale']);

            if (in_array($browser_language, $locale)) {
               $detect = $key;
            }
         }
      }
   }
}

if (isset($request->get['language']) && array_key_exists($request->get['language'], $languages) &&

$languages[$request->get['language']]['status']) {
   $code = $request->get['language'];
} elseif (isset($session->data['language']) && array_key_exists($session->data['language'], $languages)) {
   $code = $session->data['language'];
} elseif (isset($request->cookie['language']) && array_key_exists($request->cookie['language'], $languages)) {
   $code = $request->cookie['language'];
} elseif ($detect) {
   $code = $detect;
} else {
   $code = $config->get('config_language');
}

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
$document = new Document();
$registry->set('document', $document);       

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

// Affiliate
$affiliate = new Affiliate($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.
