Question

我正在使用Wordpress 4.6，WPML 3.5，WooCommerce Multilingual 3.8.6和WooCommerce版本2.6.4开发一个WooCommerce多语言商店。

代码始终返回主要语言的类别，但从不返回指定语言的翻译。

以下是代码： -

    private $lang;

    function __construct($lang = "en") {
        $this->lang = $lang;
    }

    private function getCategories() {
        try {
                $api = WC()->api->WC_API_Products;
                $categories = $api->get_product_categories();

                $products_categories = $categories["product_categories"];

                foreach($products_categories as $category) {
                    $id = absint($category["id"]);
                    $category["name"] = $this->get_translated_term_name($id, "product_cat", $this->lang);
                }

                return $products_categories;

            } catch (Exception $e) {
                error_log("Caught $e");
            }
    }

    private function get_translated_term_name($term_id, $taxonomy, $language) {

        $translated_term_id = icl_object_id($term_id, $taxonomy, true, $language);

        $translated_term_object = get_term_by('id', $translated_term_id, $taxonomy);

        return $translated_term_object->name;
    }

Answer 1

<?php
function wpa89819_wc_single_product(){

    $product_cats = wp_get_post_terms( get_the_ID(), 'product_cat' );

    if ( $product_cats && ! is_wp_error ( $product_cats ) ){

        $single_cat = array_shift( $product_cats ); ?>

        <h2 itemprop="name" class="product_category_title"><span><?php echo $single_cat->name; ?></span></h2>

<?php }
}
add_action( 'woocommerce_single_product_summary', 'wpa89819_wc_single_product', 2 );

我在此链接中找到了解决方案：

原来，WPML自动调整了分类法的ID，所以在调用get_term之前删除过滤器解决了问题，这里是代码：

    private function get_translated_term_name($term_id, $taxonomy, $language) {

        global $sitepress;
        remove_filter('get_term', array($sitepress,'get_term_adjust_id'), 1, 1);

        $translated_term_id = icl_object_id($term_id, $taxonomy, true, $language);

        $translated_term_object = get_term($translated_term_id, $taxonomy);

        add_filter('get_term', array($sitepress,'get_term_adjust_id'), 1, 1);

        return $translated_term_object->name;
}

Answer 3

此外，您可能会对get_term支持函数的行为感到惊讶。有时它不会将与提供的term_id相对应的术语作为输入参数返回，而是返回缓存结果！所以我以这种方式重写它以绕过这个。

private function getTerm($id) {
    global $wpdb;
    $id = absint($id);
    if(!$id) {
        return false;
    }
    $term = $wpdb->get_results("SELECT * FROM $wpdb->terms WHERE term_id=$id");
    return $term;

}
