I have a Field Group which has 5 ‘Text’ field types (See screenshot).

Is there a way to make sure at least one of the fields is filled in by the user?

Thanks.

You have to do your own validating and test all of the fields https://www.advancedcustomfields.com/resources/acf-validate_value/

You can look at other fields by looking at $_POST['acf']['GROUP_FIELD_KEY']['SUB_FIELD_KEY'].
