Order posts by tags count?

我正在尝试按标签数量订购帖子。我想先订购没有标签的帖子，最后订购计数最高的帖子。

我试过了，只得到了没有标签的帖子。

    $tags = get_tags();
    $tag_ids = wp_list_pluck( $tags, \'term_id\' );

    $args1 = array (
       \'orderby\'          => \'DEC\',
       \'post_type\'        => \'post\',
       \'pagination\'       => true,
       \'posts_per_page\'   => \'1\',
       \'tag__not_in\'      =>  $tag_ids,
       \'meta_key\'         => \'_thumbnail_id\',
    );

如何根据标签数量订购帖子？

$args1 = array ( \'orderby\' => \'tag_count\', \'order\' => \'DESC\', \'post_type\' => \'post\', \'pagination\' => true, \'posts_per_page\' => \'1\', // 1 post per page?! \'meta_key\' => \'_thumbnail_id\', \'suppress_filters\' => false, ); function wpse173949_posts_clauses( $pieces, $query ) { if ( $query->get( \'orderby\' ) != \'tag_count\' ) return $pieces; global $wpdb; if ( ! ( $order = $query->get( \'order\' ) ) ) $order = \'DESC\'; $pieces[ \'fields\' ] .= $wpdb->prepare( \', (SELECT COUNT(tr.object_id) FROM \' . $wpdb->term_relationships . \' tr\' . \' JOIN \' . $wpdb->term_taxonomy . \' AS tt ON tt.term_taxonomy_id = tr.term_taxonomy_id\' . \' WHERE tr.object_id = \' . $wpdb->posts . \'.ID AND tt.taxonomy = %s) AS tag_count\' , \'post_tag\' ); // Treat zero tagged posts as max int (~0). $pieces[ \'orderby\' ] = \'CASE WHEN tag_count THEN tag_count ELSE ~0 END \' . $order; return $pieces; } add_filter( \'posts_clauses\', \'wpse173949_posts_clauses\', 10, 2 ); $query = new WP_Query( $args1 ); remove_filter( \'posts_clauses\', \'wpse173949_posts_clauses\', 10 );

WP_USER_Query。‘Relationship’=>‘OR’有什么问题？

我希望所有满足任一条件1的用户OR 条件2。按姓氏排序。如果我接受条件1AND 条件2（\'关系\'=>\'和\'），查询正常。如果我取“relation”=>“OR”，我会得到所有记录和未排序的记录。怎么了？ $args = array( \'meta_query\' => array( \'relation\' => \'OR\', 0 => array( \'k
