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
$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
