Hello,
This code seems really interesting. In order to use it, do I have to write it in my theme's functions.php file?

Regards

Awesome!
It's all working on the backend but on the frontend the custom fields are not saving....? The values entered into the custom fields do NOT show:

1. On resume preview
2. On the backend in the meta fields
3. On the resume after is has been approved

But somehow the values remain on the frontend when I go back to edit the resume>

To confirm - when I create or edit the resume from the backend it all works correctly.
