WordPress：如何将没有类别的帖子添加到类别中

Question

我的WordPress中有一些帖子没有类别，它上面有2000篇文章，所以我需要将这篇文章添加到名称为＆＃34;新闻＆＃34;通过SQL

Answer 1

这应该有效：

UPDATE wp_term_relationships SET term_taxonomy_id = '3' WHERE term_taxonomy_id = '1';

3是类别＆＃34;新闻＆＃34;的ID，如果它与您不同，您可能需要更改它。 1是＆＃34;未分类＆＃34;的类别ID，因此以上内容应将1（未分类）的所有帖子ID更改为3（新闻）

编辑尝试：

 UPDATE wp_term_relationships SET term_taxonomy_id = '3' WHERE term_taxonomy_id = '';

Answer 2

我没有找到这个问题的答案，所以也许对某人会有帮助。 您可以尝试使用此代码，但改为777-添加类别ID

INSERT IGNORE INTO wp_term_relationships
(object_id, term_taxonomy_id, term_order)
SELECT 
    wp_posts.ID as object_id,
    777 as term_taxonomy_id,
    0 as term_order
FROM    wp_posts
LEFT JOIN 
        wp_term_relationships rel
ON      wp_posts.ID = rel.object_id 
LEFT JOIN 
        wp_term_taxonomy tax
ON      tax.term_taxonomy_id = rel.term_taxonomy_id 
        AND tax.taxonomy = 'category' 
LEFT JOIN 
        wp_terms term
ON      term.term_id = tax.term_id
WHERE   wp_posts.post_type = 'post' 
        AND wp_posts.post_status = 'publish' 
        AND term.term_id is null

Answer 3

UPDATE FROM `wp_posts` WHERE `post_category` SET `post_category` = '9' WHERE `post_category` = '';
