WordPress的：自動刪除x天的帖子？

Question

很長一段時間，我已經尋找一個插件，將刪除在特定的「年齡」以上的職位（如30天）。做這個的最好方式是什麼？

Answer 1

下面是一些SQL會發現每一個已經存在了30天或更長時間後：

SELECT * FROM `wp_posts` 
WHERE `post_type` = 'post' 
AND DATEDIFF(NOW(), `post_date`) > 30 

要刪除所有帖子，你可以替換SELECT * FROM與DELETE FROM - 但一定要採取備份前你做這個！

然後，您可以只cron你喜歡的那個，是一個shell腳本，PHP腳本，或任何你最舒服。

Answer 2

刪除30天post命令是：

delete FROM `wp_posts` 
WHERE `post_type` = 'post' 
AND DATEDIFF(NOW(), `post_date`) > 30 

Answer 3

delete a,b,c,d 
FROM wp_posts a 
LEFT JOIN wp_term_relationships b ON (a.ID = b.object_id) 
LEFT JOIN wp_postmeta c ON (a.ID = c.post_id) 
LEFT JOIN wp_term_taxonomy d ON (d.term_taxonomy_id = b.term_taxonomy_id) 
LEFT JOIN wp_terms e ON (e.term_id = d.term_id) 
WHERE e.term_id =<category id> 
AND a.post_type = 'post' 
AND DATEDIFF(NOW(), a.post_date) > 30
