Important: WooCommerce-qTML is no longer developed and supported, since qTranslate and mqTranslate are no longer active. Both plugins have been deprecated and merged into <a href="https://wordpress.org/plugins/qtranslate-x/" rel="ugc">qTranslate-X</a>, which aims to provide full WooCommerce support out of the box.
WooCommerce-qTML:
<ol>
<li>Ensures that (m)qTranslate will retain the selected language when moving between WooCommerce products, pages and endpoints.</li>
<li>Prevents switching to the default language in many cases of redirection (after posting product reviews, when returning to the shop after paying/cancelling an order, etc).</li>
<li>Adds qTranslate shortcode support to: product attributes, product category names and descriptions, tax descriptions, payment gateways, shipping methods.</li>
<li>Supports localized e-mail notifications for new orders, order status updates, new order notes and invoices by storing the active language every time an order is placed.</li>
</ol>
WooCommerce-qTML is provided with the following limitations:
<ul>
<li>As expected, WooCommerce-qTML helps keep the front-end of your shop properly localized. However, depending on your theme and installed WooCommerce extensions, certain strings or parts of your website might not be translated as expected.</li>
<li>The admin area is not streamlined for multilingual input. No separate input boxes exist for multilingual input – instead, WooCommerce categories & attributes must be entered using (m)qTranslate tags/shortcodes, e.g. [:en]Color[:de]Farbe].</li>
<li>Support for localized customer e-mails is included since version 1.0.0. However, extensions and 3rd party plugins that add content to e-mail notifications might not work out of the box. If you need assistance with a particular WooCommerce extension, please contact us for a quote.</li>
<li>qTranslate does not include proper support for HTTPS/protocol-less URLs. If you have an SSL certificate installed and want to use HTTPS in your WooCommerce store, you will need to tweak qTranslate in order to support viewing checkout/account pages securely.</li>
<li>WooCommerce-qTML is only recommended for use by developers, since, in most cases, customizations need to be made according to the needs of each project. The plugin is a good head-start that will save developers a few hours of research – it is not a complete multi-language solution!</li>
</ul>
Always use the plugin with the latest versions of WooCommerce/Wordress/(m)qTranslate. Using the plugin with older/newer versions of WooCommerce/WordPress/(m)qTranslate is not recommended, since new versions always introduce changes that may break the translation of a few strings, or, in extreme cases, even entire pages. You can always give it a shot and see if another combination works for you. However, we strongly encourage you to:
<ol>
<li>Always backup your entire website before updating WooCommerce or WordPress.</li>
<li>Check that a new version of WooCommerce-qTML exists before updating WC or WP and verify that the version you are upgrading to is supported.</li>
</ol>
WooCommerce-qTML will be updated as long as (m)qTranslate and WooCommerce are active and maintained.
Developers can checkout and contribute to the source code on the plugin’s <a href="https://github.com/franticpsyx/woocommerce-qtml/" rel="nofollow ugc">GitHub Repository</a>.
