如何提取Wordpress中两种不同post类型共享的标签

Posted 2021-02-17

Extract all the tags (shared between two post types) used with a specific post type

$articles_in_post_type = get_posts( array(
    'fields' => 'ids',
    'post_type' => 'post',
    'posts_per_page' => -1,
));
$tags = wp_get_object_terms( $articles_in_post_type, 'post_tag', array('ids') );
