I tried Simple Fields Plugin but could't figure out how to use my existing custom fields. I have a lot of existing custom field keys which I want only have a nicer form in Post Editor.
Is it possible to use Simple Fields with my old custom field keys and values?
Like for example custom Field "release-date", "year", etc. so I dont have to rebuild all fields and call them with my existing theme files using
get_post_meta($post->ID, 'release-date', true);
And where do I find the simple fields "show custom field key" link described here: http://simple-fields.com/documentation/getting-started/tutorial-part-2/
I don't see such a link in Field Groups, nor Box Editor of simple fields?!
