获取 Woocommerce 中特定产品类别的特定产品属性值

Question

我已经设法使用此代码获取所有颜色属性：

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

这适用于商店页面并返回所有颜色，但如何将其限制为特定类别？假设在名为“衬衫”的类别中我只有 2 种颜色，并且我只想显示这 2 种颜色。

尝试以下使用独特的轻型 SQL 查询的自定义函数：

\n\n

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

\n\n

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。

用法：

\n\n

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

\n\n

这里“Shirts”是产品类别术语名称，“pa_color”是产品属性分类\xe2\x80\xa6

\n\n

您将获得一个产品属性值（术语对象）数组，其中包含：

\n\n

\n
• 术语 ID （键term_id）
\n
• 术语名称（键name）
\n
• 术语 slug （关键slug）
\n

\n\n

您可以使用 foreach 循环来访问每个术语对象：

\n\n

// Get the "pa_color" attribute terms for product category "Shirts"\n$terms = get_attribute_terms_in_product_cat( "Shirts", "pa_color" );\n\n// Loop through each term\nforeach( $terms as $term ){\n    $term_id   = $term->term_id;\n    $term_name = $term->name;\n    $term_slug = $term->slug;\n}\n

\n
