Is there a way to get the revision count number of a post? I've seen how to get the revisions but I don't want to get the revisions just the count.


You can use wp_get_post_revisions ( int|WP_Post $post_id, $args = null ). It returns an array of revisions for the passed post ID or an empty array if a passed post does not have any revisions.

Note that the $args parameter accepts all parameters valid for WP_Query

$q = wp_get_post_revisions( 513 );
echo count( $q );
?><pre><?php var_dump($q); ?></pre><?php    


From your comments about custom fields, custom fields does not trigger the post revision system.

I'm not going to discuss how the revision system works, but in short, when a post is updated, the old and new values of the WP_Post is compared. There are a specific action for that, post_updated. If these value don't match, a revision is created (if revisions are enabled).

Now, custom fields are not part of the WP_Post object, there for, whenever you just update a custom field, a post revision will not be created as the post object remains the same. Also, custom fields also don't have a revision system, so old values are completely overwritten by new values

  • Strange. I'm not showing any revisions. Are revisions only created when the document is published? – 1.21 gigawatts Oct 13 '15 at 4:32
  • Interesting... It won't save revisions OR show the revisions panel UNLESS the document body changes. That seems like a good idea but I've been updating the custom metadata and pulling my hair out trying to figure out why no revisions were being saved!!! – 1.21 gigawatts Oct 13 '15 at 4:38
  • Revisions (if enabled) are created when a post is updated. Note that, by default, custom post types don't have revisions enabled. – Pieter Goosen Oct 13 '15 at 4:40

    To be honest, the revision system is a really crappy one which I really dont like – Pieter Goosen Oct 13 '15 at 4:42

    Please see my update. In short, custom field updates does not trigger revisions – Pieter Goosen Oct 13 '15 at 5:07
