Question

For a long time, I have searched for a plugin that will delete posts that are over a certain ‘age’ (eg. 30 days old). What is the best way to do this?

Answer 1

Here’s some SQL that will find every post that has been around for 30 days or more:

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

To delete all the posts, you can replace SELECT * FROM with DELETE FROM — but make sure you take a backup before you do this!

You can then just cron that however you like, be that a shell script, a PHP script, or whatever you’re most comfortable with.
