Mysql Wordpress sql：获取帖子的所有类别

我有一篇文章，它有多个类别，我如何通过sql查询得到这篇文章的所有类别？非常感谢。

检查此代码-

$post_categories = wp_get_post_categories( $post_id );
$cats = array();

foreach($post_categories as $c){
    $cat = get_category( $c );
    $cats[] = array( 'name' => $cat->name, 'slug' => $cat->slug );
}

试试看

select c.*
from wp_categories c
inner join wp_post2cat pc on pc.category_id = c.cat_ID
inner join wp_posts p on pc.post_id = p.id
where p.id = 1

试一试

您可以使用以下SQL获取帖子类别：

SELECT wt.* FROM wp_posts p
 INNER JOIN wp_term_relationships r ON r.object_id=p.ID
 INNER JOIN wp_term_taxonomy t ON t.term_taxonomy_id = r.term_taxonomy_id
 INNER JOIN wp_terms wt on wt.term_id = t.term_id
WHERE p.ID=1 AND t.taxonomy="category"

非常感谢，它非常完美：）-1次安装都会中断一个表前缀！=<代码>可湿性粉剂。哦，在多站点安装中也是如此。WordPress没有这些表非常感谢，它非常完美：）-1在每个带有表前缀的安装中中断！=<代码>可湿性粉剂。哦，还有多站点安装。WordPress没有这些表
