问题概述

将 Barn2 提供的 WooCommerce Product Options 与 WPML 搭配使用时，产品选项字符串在购物车、结账和迷你购物车中会显示为未翻译，即使它们在产品页面上已正确翻译。

临时解决方法

继续操作前，请确保已对网站进行完整备份。

• 在主题的 functions.php 文件中，粘贴以下代码：

  /**
   * Translate WooCommerce Product Options texts when adding to cart
   * using the plugin's own WPML integration.
   */
   
  add_filter( 'woocommerce_add_cart_item_data', 'my_wpo_translate_cart_meta_with_wpml', 20, 4 );
   
  function my_wpo_translate_cart_meta_with_wpml( $cart_item_data, $product_id, $variation_id, $quantity ) {
   
      // If there are no WPO options in this cart item, do nothing.
      if ( empty( $cart_item_data['wpo_options'] ) ) {
          return $cart_item_data;
      }
   
      // Make sure the plugin classes exist (plugin is active and loaded).
      if (
          ! class_exists( 'Barn2PluginWC_Product_OptionsPlugin_Factory' ) ||
          ! class_exists( 'Barn2PluginWC_Product_OptionsIntegrationWPML' ) ||
          ! class_exists( 'Barn2PluginWC_Product_OptionsModelOption' )
      ) {
          return $cart_item_data;
      }
   
      // Get the plugin instance and the WPML integration helper.
      $plugin           = Barn2PluginWC_Product_OptionsPlugin_Factory::create( '', '' );
      $wpml_integration = new Barn2PluginWC_Product_OptionsIntegrationWPML( $plugin );
   
      foreach ( $cart_item_data['wpo_options'] as $option_id => &$option_data ) {
   
          // Load the option model so we can access the original data.
          $option = Barn2PluginWC_Product_OptionsModelOption::find( $option_data['option_id'] ?? 0 );
          if ( ! $option ) {
              continue;
          }
   
          // 1) Translate the option name (the "key" shown in cart/checkout).
          $translated_name     = $wpml_integration->translate_string( $option->name, $option, 'option_name' );
          $option_data['name'] = $translated_name;
   
          // 2) Translate each choice label, if any.
          if ( empty( $option_data['choice_data'] ) || empty( $option->choices ) ) {
              continue;
          }
   
          // Build a map: choice_id => index, to reproduce the same index WPML uses.
          $index_by_id = [];
          foreach ( $option->choices as $idx => $choice ) {
              if ( isset( $choice['id'] ) ) {
                  $index_by_id[ $choice['id'] ] = $idx;
              }
          }
   
          // Normalize the stored value to an array (covers both single and multi).
          $values = is_array( $option_data['value'] ) ? $option_data['value'] : [ $option_data['value'] ];
   
          foreach ( $option_data['choice_data'] as $i => &$choice_data ) {
              if ( ! isset( $choice_data['label'] ) ) {
                  continue;
              }
   
              // For free-text fields, there are usually no predefined choices to translate.
              if ( empty( $index_by_id ) ) {
                  continue;
              }
   
              $value_for_this_choice = $values[ $i ] ?? null;
              if ( ! isset( $index_by_id[ $value_for_this_choice ] ) ) {
                  continue;
              }
   
              $choice_index   = $index_by_id[ $value_for_this_choice ];
              $original_label = $option->choices[ $choice_index ]['label'];
   
              // Translate the choice label using the same context and index as when registered.
              $choice_data['label'] = $wpml_integration->translate_string(
                  $original_label,
                  $option,
                  'choice_label',
                  $choice_index
              );
          }
      }
   
      return $cart_item_data;
  }
  
     



• 注意：如果在将产品添加到购物车后更改语言，标签将不会被“翻译”：它们将保持添加产品时处于活动状态的语言（就像存储固定文本的任何其他元数据一样）。但在该阶段切换语言的情况很少见。 Barn2 很快会应用永久修复，部署后请移除添加的临时解决方法。
