获取Woocommerce中特定产品类别的特定产品属性值

请尝试以下使用唯一的轻型SQL查询的自定义函数：

function get_attribute_terms_in_product_cat( $category_term_name, $attribute_taxonomy ){
    global $wpdb;

    $terms = $wpdb->get_results( "SELECT DISTINCT t.*
        FROM {$wpdb->prefix}terms as t
        JOIN {$wpdb->prefix}term_taxonomy as tt ON tt.term_id = t.term_id
        JOIN {$wpdb->prefix}term_relationships as tr ON tt.term_taxonomy_id = tr.term_taxonomy_id
        WHERE tt.taxonomy LIKE '$attribute_taxonomy'
        AND tr.object_id IN ( SELECT DISTINCT tr2.object_id
            FROM {$wpdb->prefix}term_relationships as tr2
            JOIN {$wpdb->prefix}term_taxonomy as tt2 ON tt2.term_taxonomy_id = tr2.term_taxonomy_id
            JOIN {$wpdb->prefix}terms as t2 ON tt2.term_id = t2.term_id
            WHERE tt2.taxonomy LIKE 'product_cat' AND t2.name = '$category_term_name'
        )" );

    return $terms;
}

代码进入您的活动子主题（或活动主题）的function.php文件中。经过测试和工作。

用法：

// Get the "pa_color" attribute terms for product category "Shirts"
$terms = get_attribute_terms_in_product_cat( "Shirts", "pa_color" );

这里的“衬衫”是产品类别的术语名称，“ pa_color”是产品属性分类法…

您将获得一个包含以下内容的产品属性值（条件对象）数组：

• 术语ID （键term_id）
• 术语名称（键name）
• 词条（键slug）

您可以使用foreach循环访问每个term对象：

// Get the "pa_color" attribute terms for product category "Shirts"
$terms = get_attribute_terms_in_product_cat( "Shirts", "pa_color" );

// Loop through each term
foreach( $terms as $term ){
    $term_id   = $term->term_id;
    $term_name = $term->name;
    $term_slug = $term->slug;
}
