将Opencart标头拉到wordpress

Question

I am trying to get opencart header to wordpress. Opencart is installed within wordpress directory within "store" folder. With some help, I am able to get opencart page into wordpress. The below code is saved as headerX.php and it is called in page.php withing wordpress. This pulls the entire page into wordpress home page. Everything is good uptil now except that $response->output(); will get the entire opencart page including the products into the main page.

How do I get only the header and footer into wordpress and ignore (or not include) stuff between?

Thanks for any help.

There are many ways you can do this and this is also a common feature a lot of people are looking for; you can find tons of integrating open cart with wordpress solutions on the internet. Good that it's common.

Have you tried looking into opencart plug in for wordpress?

Wordpress or Opencart, all these system have separate header and footer includes which you can call on other system; you will need to include all the necessary files in order to have it included successfully.

I found this article to be useful: https://wordpress.org/support/topic/opencart-wordpress-integration

You can try the following and give it a shot. (Make sure you fix to the correct path)

1. Create file headerX.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) {

   $action = new Action($request->get['route']);
} else {
   $action = new Action('common/home');
}

// Dispatch
$controller->dispatch($action, new Action('error/not_found'));

2. Include headerX.php in page.php ie Place the statement below on line 1 at the very top of page.php

<?php require_once ('headerXYZ.php');?>

3. Right after the opening body tag of your external page.php page add the following code

  <?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');
    ?>

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.

Here the plugin: https://github.com/saRca/op2wp
