Ok, I’m having some trouble updating my custom field to override the
format_single_value method in the RWMB_Choice_Field. I’m extending the
RWMB_Input_List_Field class because I want a list of checkboxes. Basically, I want to be able to pre-fill the checkbox options after a user as applied a Category to a CPT.
However, I’m getting
Undefined index: multiple when I try to do that. I guess that makes sense because I’m using multiple values, but trying to override the
format_single_value method. Is there another method in
RWMB_Input_List_Field that I should be using instead?
Thanks in advance.
P.S. I can make a new post if that is preferred.
