我正在使用下面的查询从自定义分类中输出所有链接。它从分类“单词”中输出所有标记为“http”的帖子。

我想从输出中排除一些一般类别。所以，菲。它只输出媒体和新闻类别的链接。实现这一目标的最佳方法是什么？

$wp_query->request = "

SELECT DISTINCT *

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 = 'post' 

AND $wpdb->posts.post_status = 'publish'

AND $wpdb->term_taxonomy.taxonomy = 'words'

AND $wpdb->terms.slug = 'http'

ORDER BY $wpdb->posts.post_date DESC

LIMIT $ppp OFFSET $offset";

$pagelinkposts = $wpdb->get_results($wp_query->request, OBJECT);

我通过使用另一个插件的代码以某种方式自己找到了解决方案。如果其他人想要实现相同的目标，请在 ORDER BY 行之前添加以下内容（并将类别 ID 更改为您想要包含的内容。）

AND object_id IN
           (
            SELECT object_id
            FROM $wpdb->term_relationships AS r
            JOIN $wpdb->term_taxonomy AS x ON x.term_taxonomy_id = r.term_taxonomy_id
            JOIN $wpdb->terms AS t ON t.term_id = x.term_id
            WHERE   x.taxonomy = 'category'
            AND t.term_id IN  (category-ids))
