I have a form to edit posts in the front end. Most of the fields are working, except I have a grouped field with two nested text fields inside of it. These fields are not saving. When editing from the backend they do work.
If I run some logging on the acf_update_metadata() function, I see that for the front end form its trying to pass an array to the update_metadata function
For the grouped field the name is the group name, value is an array of values.
When I save from the back end, I can see that each subfield is passed through the acf_update_metadata() function with name = groupname_fieldname, and value is the value.
It appears I need to do some preprocessing on group fields, is that correct? I cannot find any documentation on that…
