Reply To: Programmatically modify field value prior to displaying in admin?

Thanks Anh, that's the one I've been looking at and experimenting with.

Do you know the proper way to use it?

If I wanted to create a field that could be used for the site title (ID: site_name), for example, I was trying the following without success:

apply_filters( 'rwmb_field_meta', 'Title Here', 'site_name', false );
apply_filters( 'rwmb_site_name_field_meta', 'Title Here');

I also tried inserting 'Title Here' into an array per the docs but didn't work for me either.

Any thoughts are much appreciated!
