将变体价格添加到 Woocommerce 中的可变产品下拉项目名称中

Question

我正在使用此代码来获取可变产品选项

$terms = wc_get_product_terms( $bundle_product_id, $name, array( 'fields' => 'all' ) );
foreach ( $terms as $term ) {
    if ( !in_array( $term->slug, $options ) ) {
        continue;
    }
    echo '<option value="' . esc_attr( $term->slug ) . '" ' . selected( sanitize_title( $selected_value ), sanitize_title( $term->slug ), false ) . '>' . apply_filters( 'woocommerce_variation_option_name', $term->name )  . '</option>';
}

仅当您在变量产品中设置的变体只有一种产品属性时（因此只有一个下拉列表），它才有效。

如果您的可变产品中有多个下拉菜单，由于变体是不同产品属性值的组合，因此它不会按逻辑工作。

因此，以下代码将在唯一的产品属性下拉列表中显示产品变体价格：

代码位于活动子主题（或活动主题）的 function.php 文件中。经过测试并有效。
