Admin Texts / wp_options

Polylang fully supports WPML configuration files

Let's look at how this works

Goal:

Translating "Flat Rate" Label on the Cart Page

WooCommerce Shipping Options

Flat Rate - Method Title

WP Options

/wp-admin/options.php

woocommerce_flat_rate_settings

Create XML File:

wpml-config.xml

Save file in active theme directory

Polylang – Settings – Strings translation

New String named Flat Rate

Polylang – Settings – Strings translation

Translate into available languages

Cart Page

Correct Label (in French) showing up

WPML Config file

All Standard Shipping Options
