我需要类似的东西。这就是我所做的：

$args = array(
        \'post_status\' => \'publish\',
        \'tax_query\' => array(
            array(
                \'taxonomy\' => get_query_var(\'taxonomy\'),
                \'field\' => \'slug\',
                \'terms\' => get_query_var(\'term\'),
            )
        ),
    );
    $products = new WP_Query($args);
    $attributes = array();
    while ($products->have_posts()) : $products->the_post();
        $post_atts = get_the_terms(get_the_ID(), \'pa_\' . $attr);
        if ($post_atts) {
            foreach ($post_atts as $x) {
                if(!in_array($x, $attributes)){
                    $attributes[]=$x;
                }
            }
        }
    endwhile;
    print_r($attributes1);
