在 Woocommerce 中获取特定产品类别的特定产品属性值

Question

我已经用这段代码获取了所有的颜色属性：

$color_terms = get_terms(
        array(
        'taxonmy'=>'pa_color'
    ));

这适用于商店页面和 returns 所有颜色，但我如何将其限制在特定类别？假设在名为 "Shirts" 的类别中，我只有 2 种颜色，我只想显示这 2 种颜色。

尝试以下使用独特灯光 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。已测试并有效。

用法：

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

这里"Shirts"是产品类别术语名称，"pa_color"是产品属性分类…

您将获得一组产品属性值（术语对象），其中包含：

术语 ID （关键字 term_id）
术语名称(关键字name)
术语 slug (key slug)

您可以使用 foreach 循环访问每个术语对象：

// 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;
}
