I am trying to: Add user-meta fields by 3rd party plugin which are stored in wordpress db as to metafields (screen 1) - cjl_birthday and cjl_birthmonth (both are numbers from 1-31 or 1-12 respectively). I need user updates them by CRED form.
For some reasons I can't see them in Toolset>Settings>Front-End Content> Hidden Custom Value (screen3).
I've tried to add them with shortcodes (screen 2 ) no luck.
my CRDE frm looks like this ('your-bdate' field works fine via User Fields settings, problem is with cjl* fields):
The option to show hidden fields doesn't help you here because hidden fields have a name beginning with underscore (e.g. "_hidden"), so your fields are not hidden.
The cred_field shortcode is intended for use with Types fields.
For 3rd-party custom fields you need to use generic fields: use the Add Generic Fields button and enter the field slug for it to generate the required markup with the options in JSON format.
Note, though, that generic fields are not normally saved to the database. If you want the field to be saved, you must add the option "persist" : 1, to the existing options inserted.
