WPML WooCommerce multilingual checkout

To achieve a multilingual checkout functionality in WooCommerce using WPML, you can use the wcml_checkout_language filter hook provided by the WPML plugin. This filter allows you to set the language for the checkout page based on the selected language in WPML.

Here’s an example code snippet that demonstrates how to set the language for the WooCommerce checkout page based on the selected language in WPML:

function wpsnippets_set_checkout_language( $lang ) {
    if ( function_exists( 'wcml_languages' ) ) {
        $wcml = wcml_languages();
        $current_language = $wcml->get_current_language();
        $lang = $current_language;
    }
    return $lang;
}
add_filter( 'wcml_checkout_language', 'wpsnippets_set_checkout_language' );

In this code snippet, we define a custom function wpsnippets_set_checkout_language that takes the current language as an argument. We then check if the WPML plugin is active by using the function_exists function. If WPML is active, we retrieve the current language using the wcml_languages function and set it as the language for the checkout page. Finally, we return the updated language.

By adding this code snippet to your theme’s functions.php file or a custom plugin, the language for the WooCommerce checkout page will be automatically set based on the selected language in WPML.

This code snippet can be useful if you have a multilingual WooCommerce store using WPML and want to ensure that the checkout page is displayed in the correct language for your customers.

Examples

Example 1: Adding Language Switcher to WooCommerce Checkout Page

This use case demonstrates how to add a language switcher to the WooCommerce checkout page using WPML. The code example adds a language switcher dropdown to the WooCommerce checkout page template.

function wpsnippets_add_language_switcher_to_checkout() {
    if ( function_exists( 'icl_get_languages' ) ) {
        $languages = icl_get_languages( 'skip_missing=0' );
        if ( ! empty( $languages ) ) {
            echo '<div class="language-switcher">';
            foreach ( $languages as $language ) {
                echo '<a href="' . esc_url( $language['url'] ) . '">' . esc_html( $language['native_name'] ) . '</a>';
            }
            echo '</div>';
        }
    }
}
add_action( 'woocommerce_before_checkout_form', 'wpsnippets_add_language_switcher_to_checkout', 10 );

The code checks if the WPML plugin is active and retrieves the available languages. It then loops through the languages and outputs a language switcher dropdown on the WooCommerce checkout page.

Example 2: Translating WooCommerce Checkout Fields

This use case demonstrates how to translate the WooCommerce checkout fields based on the selected language using WPML. The code example translates the “Billing Address” and “Shipping Address” fields on the checkout page.

function wpsnippets_translate_checkout_fields( $fields ) {
    if ( function_exists( 'icl_translate' ) ) {
        $fields['billing']['billing_address_1']['label'] = icl_translate( 'woocommerce', 'Billing Address', 'Billing Address' );
        $fields['shipping']['shipping_address_1']['label'] = icl_translate( 'woocommerce', 'Shipping Address', 'Shipping Address' );
    }
    return $fields;
}
add_filter( 'woocommerce_checkout_fields', 'wpsnippets_translate_checkout_fields' );

The code uses the icl_translate() function from WPML to translate the labels of the “Billing Address” and “Shipping Address” fields on the WooCommerce checkout page.

Example 3: Translating WooCommerce Checkout Error Messages

This use case demonstrates how to translate the error messages displayed on the WooCommerce checkout page using WPML. The code example translates the error messages for invalid email and required fields.

function wpsnippets_translate_checkout_error_messages( $messages ) {
    if ( function_exists( 'icl_translate' ) ) {
        $messages['invalid_email'] = icl_translate( 'woocommerce', 'Invalid email address.', 'Invalid email address.' );
        $messages['required'] = icl_translate( 'woocommerce', 'This field is required.', 'This field is required.' );
    }
    return $messages;
}
add_filter( 'woocommerce_checkout_error_messages', 'wpsnippets_translate_checkout_error_messages' );

The code uses the icl_translate() function from WPML to translate the error messages for invalid email and required fields on the WooCommerce checkout page.
