我希望在主要网站上找到并替换某个关键字。
我通常会使用像
这样的东西UPDATE wp_posts
SET post_content = REPLACE (post_content, 'Item to replace here', 'Replacement text here');
但是,我不希望更新跨越整个网站,我希望将其限制为只有一个类别。
谁能告诉我如何实现这个目标?

更新:更准确地说,查询应该是
UPDATE wp_term_relationships r JOIN wp_posts p
ON r.object_id = p.id JOIN wp_terms t
ON r.term_taxonomy_id = t.term_id JOIN wp_term_taxonomy x
ON r.term_taxonomy_id = x.term_taxonomy_id
SET p.post_content = REPLACE(post_content, 'Item to replace here', 'Replacement text here')
WHERE t.name = 'My Category'
AND x.taxonomy = 'category'
AND x.parent = 0 -- top level category
更新任何内容之前注意::
1)您可以通过发布
来查看哪些帖子会受到影响SELECT *
FROM wp_term_relationships r JOIN wp_posts p
ON r.object_id = p.id JOIN wp_terms t
ON r.term_taxonomy_id = t.term_id JOIN wp_term_taxonomy x
ON r.term_taxonomy_id = x.term_taxonomy_id
WHERE t.name = 'My Category'
AND x.taxonomy = 'category'
AND x.parent = 0 -- top level category
2)确保您的wordpress数据库具有可靠的备份。
