NAME

       HTML::FormFu::Filter::CopyValue - copy the value from another field

SYNOPSIS

          elements:
             - type: Text
               name: username
             - type: Text
               name: nickname
               filters:
                  - type: CopyValue
                    field: username

DESCRIPTION

       Filter copying the value of another field if the original value of this field is empty.

CAVEATS

       If the original field contains an invalid value (a value that will be constrained through
       a constraint) that invalid value will be copied to this field (the field with the
       CopyValue filter).  So, the user has to change two fields, or you can remove the invalid
       value in a custom constraint.
