Thank you for getting in touch. Unfortunately no its not possible to have the custom fields natively in the revisions using our Types plugin.
This is something that would need to be done using some 3rd party custom code like this below. hidden link
Or you can try using the plugin in the github link below. hidden link
If you're not sure of how to implement this as it will take a little PHP knowledge to do so, we have a list of developers that you can contact to get this setup for you. https://toolset.com/contractors/
I haven't tested either of these solutions, however it is a step in the right direction to get this working for you.
OK, I will take a look over the links you provided.
Please note that several of your competitors in the custom fields segment (ACF, PODS, metabox) have either integrated or third party plug and play solutions for including custom fields in revisions.
I think that it is a very useful feature and I've seen multiple threads in your forums seeking for that. Please consider this in your future releases.
I filed the feature request.
I also tried the solution on hidden link
I followed the directions and made the required PHP adjustments in the functions.php file but unfortunately, it did not work for me. It probably requires deeper code customization to get it to work.
Thanks again. I'm familiar with the 'wpcf-' prefix from an Essential Grid implementation we had in the past and I used it accordingly in this case.
If you are aware of any resource or contact that successfully implemented the Toolset Fields in revisions using the solutions you added before, I would be glad to know of them as it may provide me with specific guidance.
