此代码获得10个链接到term_name的所有类型的帖子;
global $wp_query;
query_posts( array(
"taxonomy_name" => "term_name",
'showposts' => 10 )
);
此代码获得10个自定义帖子类型“消息”的帖子;
global $wp_query;
query_posts( array(
'post_type' => 'message'
'showposts' => 10 )
);
但是,此代码始终忽略post_type要求,但仍选择链接到term_name的所有帖子类型;
global $wp_query;
query_posts( array(
'post_type' => 'message' ,
"taxonomy_name" => "term_name",
'showposts' => 10 )
);
我看不出两者是如何单独工作的,但除非它可能是一个错误,否则他们不会一起工作 - 任何想法?

看起来像个错误。你试过custom select query吗?这应该这样做:
$querystr = "
SELECT *
FROM $wpdb->posts
LEFT JOIN $wpdb->term_relationships ON($wpdb->posts.ID = $wpdb->term_relationships.object_id)
LEFT JOIN $wpdb->term_taxonomy ON($wpdb->term_relationships.term_taxonomy_id = $wpdb->term_taxonomy.term_taxonomy_id)
LEFT JOIN $wpdb->terms ON($wpdb->term_taxonomy.term_id = $wpdb->terms.term_id)
WHERE $wpdb->posts.post_type = 'message'
AND $wpdb->posts.post_status = 'publish'
AND $wpdb->term_taxonomy.taxonomy = 'taxonomy_name'
AND $wpdb->terms.slug = 'term_name'
ORDER BY $wpdb->posts.post_date DESC
LIMIT 10
";
$pageposts = $wpdb->get_results($querystr, OBJECT);
我在构建查询时使用了this answer。

已提交 - core.trac.wordpress.org/ticket/13020。修复只是将query.php文件的一行更改为和if语句,以检查post_type是否为空。

使用'category_name'代替'taxonomy_name'。适用于WP 3.5.2
query_posts( array(
'post_type' => 'message',
'category_name' => 'term_name',
'showposts' => '10' )
);
