How to translate extra fields with WPML?

Requires the Product Feed Translation Addon — WPML support is now part of the Product Feed Translation Addon. Install the addon alongside Product Feed Elite to use WPML with your feeds.

If you use WPML to run a multilingual WooCommerce store, you’ve probably noticed that the extra fields added by Product Feed Elite — like Brand, GTIN, and Color — don’t show up in the standard WPML product translation screen. That’s because WPML doesn’t know about these custom meta fields by default.

You can fix this by adding a Custom XML Configuration in WPML’s settings. Once added, WPML picks up each extra field you’ve enabled, so your translators can update them alongside the rest of the product content.

Prerequisites

Before you start, make sure:

For detailed instructions on setting up WPML with the addon, see How to set up WPML with the Product Feed Translation Addon.

How to add extra fields to WPML translation

  1. Go to WP Admin → WPML → Settings.
  2. Click the Custom XML Configuration tab.
  3. Add the custom field tags that match your Extra Field settings — use the reference list below to find the correct IDs.
  4. Click Save.
  5. Open any product’s translation page — the extra fields now appear as translatable fields.

Frequently asked questions

I added the configuration but the extra field still doesn’t appear in WPML — what now?
Check that you saved the configuration and cleared any caching plugins. Also confirm the Extra Field is enabled in your feed settings — WPML only exposes fields that are active. If the field still doesn’t appear, open a support ticket and include a copy of your Custom XML Configuration.
Does this also work with Polylang or TranslatePress?
No. This configuration method is specific to WPML’s Custom XML Configuration feature. Polylang and TranslatePress use different mechanisms for registering custom fields. Contact support if you need guidance for those plugins.

Need more help?

If you’re on Product Feed Elite, open a support ticket and we’ll help you sort it out.

If you’re on Product Feed Pro, post your question on the WordPress.org support forum.
