Question

如果帖子属于特定类别，我需要附加内容以发布内容。这是我必须显示该类别中所有帖子的代码。

SELECT * FROM wp_posts
LEFT JOIN wp_term_relationships ON
(wp_posts.ID = wp_term_relationships.object_id)
LEFT JOIN wp_term_taxonomy ON
(wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id)
WHERE wp_posts.post_status = 'publish'
AND wp_term_taxonomy.taxonomy = 'category'
AND wp_term_taxonomy.term_id = 1
ORDER BY post_date DESC

我需要编写更新查询来附加帖子内容。这是：

UPDATE Table SET Field=CONCAT(Field,'your extra html');

如何使用select查询的结果编写更新查询？

它可以帮到你：

UPDATE wp SET Field=CONCAT(Field,'your extra html') WHERE wp_posts LEFT JOIN wp_term_relationships ON (wp_posts.ID = wp_term_relationships.object_id) LEFT JOIN wp_term_taxonomy ON (wp_term_relationships.term_taxonomy_id = wp_term_taxonomy.term_taxonomy_id) AND wp_posts.post_status = 'publish' AND wp_term_taxonomy.taxonomy = 'category' AND wp_term_taxonomy.term_id = 1 ORDER BY post_date DESC

如果它们属于特定类别，则通过SQL更新Wordpress帖子？
