Is it possible & how to enable importing of all the products with the same SKU at once?

• If you are using some plugin to translate your products to multiple languages.
• Hence in such scenarios adding the same CSP rules to all the translated copies will be required.
• If the same SKU is assigned to all the translated copies.
• The following hook can be used to replicate the rule for all of the translated copies during an import.

“wdm_check_for_product_translations”

• The following example will demonstrate how you can use this hook to import the same rule for all the products having the same SKU.(WPML)

add_filter('wdm_check_for_product_translations', 'wdmWPMLTranslations', 99, 2);

function wdmWPMLTranslations($status, $productId) {
    /**
     * function_exists('icl_object_id') is used to check if WPML is active
     */
    if (empty($productId) || $productId<=0 || !function_exists('icl_object_id')) {
        return false;
    }

    /**
     * Add the WPML language codes of the languages you are using on your site
     * to the following array $langArray
     */
    $langArray        = array('hi', 'nl');

    $translationIds = array();
    foreach ($langArray as $language) {
        $langId        = apply_filters( 'wpml_object_id', $productId, 'product', true, $language);
        if ($langId !== $productId) {
            $translationIds[] = $langId;
        }
    }

    if (!empty($translationIds)) {
        return $translationIds;
    }

    return false;
}

• The function above “wdmWPMLTranslations” returns all the related product ids to the current product hence, the same rules get imported for all those translated products.
