Problem: If you're using WPML for multilingual support in your WooCommerce store and notice that stock updates via the Baselinker API only reflect in the default language (Polish) and not in the translated versions (e.g., English), this might be due to the Baselinker API not being integrated with WPML. As a result, updates made through the API do not trigger WPML's synchronization processes. Solution: We recommend contacting the Baselinker developers to suggest integration with WPML through our Go Global Program, which helps ensure compatibility: Go Global Program. For a temporary workaround, you can try to implement custom development to hook into WPML's synchronization processes. Specifically, you can use the
wpml_sync_custom_field
hook, detailed here: wpml_sync_custom_field. Additionally, you might consider creating a custom function to trigger stock synchronization across translations. Below is a conceptual example of how you might approach this:
function my_trbl_sync_stock() {
global $sitepress;
$results = get_original_products_and_variations();
foreach ( $results as $product ) {
if ( get_post_meta( $product->ID, '_manage_stock', true ) === 'yes' ) {
$translations = $sitepress->get_element_translations( $product->trid, $product->element_type );
$min_stock = false;
$stock_status = 'instock';
// collect min stock.
foreach ( $translations as $translation ) {
$stock = get_post_meta( $translation->element_id, '_stock', true );
if ( ! $min_stock || $stock < $min_stock ) {
$min_stock = $stock;
$stock_status = get_post_meta( $translation->element_id, '_stock_status', true );
}
}
// update stock value.
foreach ( $translations as $translation ) {
update_post_meta( $translation->element_id, '_stock', $min_stock );
update_post_meta( $translation->element_id, '_stock_status', $stock_status );
}
}
}
return true;
}
function get_original_products_and_variations() {
global $wpdb;
$results = $wpdb->get_results(
"
SELECT p.ID, t.trid, t.element_type
FROM {$wpdb->posts} p
JOIN {$wpdb->prefix}icl_translations t ON t.element_id = p.ID AND t.element_type IN ('post_product', 'post_product_variation')
WHERE p.post_type in ('product', 'product_variation') AND t.source_language_code IS NULL
"
);
return $results;
}
You can then call my_trbl_sync_stock() after your programmatic update.
Please note that this is a conceptual example and not officially supported or tested. Always back up your site before implementing custom code.
If this solution does not apply to your case, or if it seems outdated, we highly recommend checking related known issues at https://wpml.org/known-issues/, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If issues persist, please open a new support ticket at WPML support forum.
