This article provides guidelines for configuring HTTPS for your X-Cart store.

Obtain an SSL certificate

To use HTTPS for your X-Cart store site, you need to obtain an SSL certificate and have it properly installed and configured on your web server. You also need to monitor your SSL certificate expiration date and be ready to renew it when necessary.

The majority of hosting companies help their customers to purchase SSL certificates or provide their own Shared SSL URLs. If your hosting company does not render such services, you will need to purchase a certificate on your own.

We will be glad to assist you with this issue. You can purchase SSL certificates from our company. We sell SSL certificates provided by the world's leading Certification Authority, Comodo Group. For details, conditions and prices, please see http://www.x-cart.com/ssl/.

If you are on a dedicated server, we can offer you our service on analyzing and configuring your server and/or install an SSL Certificate on it. Please note that we will need the 'root' access to your server over SSH or the 'Administrator' access over MS Remote Access Desktop to complete these tasks.

Configure the HTTPS server in X-Cart

Once you have an SSL certificate for your store site installed and configured, you should adjust the HTTPS server settings in X-Cart. If your HTTPS host differs from your HTTP host, you will need to edit the file <xcart_dir>/config.php specifying your HTTPS host in the variable $xcart_https_host.

Enable HTTPS for your store

Enable HTTPS for the entire X-Cart store site

Method 1. Use for web servers with support for .htaccess, like apache

If you are using a web server of the above-named type, to set your entire X-Cart store to operate over HTTPS, you should add the following code to the .htaccess file after the line "RewriteBase":

RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L] 

If the canonical URL of your site is known, it will be even better to add the rules as follows:

RewriteCond %{HTTPS} off
RewriteRule ^(.*)$ https://example.com/$1 [^] [R=301,L]

(Be sure to replace "example.com" with your actual canonical URL). The above code should be added before the code for handling Clean URLs.

You can also use the following instructions: https://www.sslshopper.com/apache-redirect-http-to-https.html

Method 2. Use for servers like nginx.conf

Convert the rules cited in Method 1 above to nginx.conf as follows:

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    server_name _;
    return 301 https://$host$request_uri;
}

Method 3. Use in addition to Methods 1 or 2 above or as a standalone method if Methods 1 or 2 cannot be used

X-Cart versions 4.7.9 and later:
To switch your entire X-Cart store to HTTPS:

  1. In your X-Cart store's Admin area, go to the 'General settings/Security options' page and scroll down to the HTTPS options section.
  2. Enable the 'Use secure protocol (HTTPS)' option:
    Xc4 use secure protocol 479nlater.png
  3. Save the changes.

X-Cart versions prior to 4.7.9:
To switch your entire X-Cart store to HTTPS, edit the file https.php. Find the line:

function is_https_link($link, $https_scripts) {

and replace it with

function is_https_link($link, $https_scripts) {
return true;

Enable HTTPS for the login, registration, checkout and payment pages (X-Cart versions prior to 4.7.9)

If you do not wish to enable HTTPS for the entire store site but need HTTPS for the login, registration, checkout and payment pages:

  1. In your X-Cart store's Admin area, go to the 'General settings/Security options' page and scroll down to the HTTPS options section.
  2. Enable the 'Use secure protocol (HTTPS) for login, registration, checkout and payment pages' option:
    Xc4 use secure protocol before479.png
  3. If you wish, enable the following HTTPS options on the same page:
  4. Save the changes.
  5. If using X-Cart 4.5.4 or earlier, go to the Payment Methods configuration page and specify which payment methods should work using the HTTPS protocol. Save the changes.

Enable HTTPS for specific php scripts

If you do not wish to enable HTTPS for the entire store site but just need to secure some php scripts in your X-Cart store so they can only be accessed via HTTPS, you should add the scripts that need to be secured to the 'https_scripts' array in the file <xcart_dir>/https.php. You can find some examples of how that can be done right in the file <xcart_dir>/https.php:

$https_scripts[] = 'login.php';
$https_scripts[] = array(
'cart.php',
"mode=checkout",
);

HTTPS Proxy

If your web server does not use SSL certificates, and you are running an HTTPS Proxy instead, you may need to configure some additional settings to enable your X-Cart work over SSL (secure connection). In the file include/https_detect.php, specify the proxy IP address and set the $HTTPS variable to 'true':

if ($_SERVER['REMOTE_ADDR'] == '192.160.1.1') {
$HTTPS_RELAY = true;
$HTTPS = true;
}

If you are not sure whether your web server uses SSL certificates or runs behind an HTTPS Proxy, contact your hosting service provider or server administrator or email our technical support - we will help you find that out.

Troubleshooting

If you experience problems with external services (payment / shipping) working over https while using curl/libcurl as the https module, try adding the following line to top.inc.php:

define('USE_CURLOPT_SSL_VERIFYPEER', 1);

after

 
$xcart_dir = rtrim(realpath($xcart_dir), XC_DS);
