How To Manage AutoSave and Post Revisions In WordPress MU?

Posted by


WPMU has a built in autosave feature that automatically saves when the author is adding/editing a post. By default, the autosave kicks in every minute and on my computer/connection averages about 3 seconds to complete. You can alter the autosave behaviour by adding a couple defines to your wp-config.php:

define(‘AUTOSAVE_INTERVAL’, 600);

The autosave interval is in seconds. An interval of 600 is 10 minutes. I would not have the autosave interval set to less than 5 minutes. 10 minutes is still a fairly reasonable interval.

A second feature that has been added is post revisions. A user can access these via the bottom of the write post area. If post revisions go unmanaged, they are likely to significantly enlarge the size of database.

define(‘WP_POST_REVISIONS’, 3);

With this define WPMU to only keep 3 revisions. When the 4th revision is saved the first is purged off. Hence, it will not enlarge database as it was. You can change the wp_post_revisions settings upon the requirement.

That’s it!
