Keep 10 revisions per post

Keeps the last 10 revisions of each post and page instead of every one, so the database doesn’t fill up with old versions.

Type PHP
Runs Everywhere (runs as WordPress loads)
Category Performance
Tested with WordPress 7.1

PHP

<?php

// Change 10 to the number you want to keep (0 turns revisions off).
add_filter( 'wp_revisions_to_keep', static fn() => 10 );

Good to know

Older revisions are removed the next time a post is saved.

Performance: Small changes that save the server and the browser some work.

Install it in one click

It's already in the Snipfire plugin's library. Enter your site's address and it opens there, ready to install. It arrives switched off, and Snipfire checks the code and test-loads your site before you switch it on.

Needs Snipfire on that site and you logged in as an administrator. Your address stays in this browser; we don't see it. Get Snipfire free

Or add it by hand

Click + New and choose PHP.
Paste the code and give it a name.
Where: Everywhere (runs as WordPress loads).
Save and switch it on.

Works in any snippet plugin, or a child theme's functions.php. Without the safety net, though.
