NAME

HTML::FormFu::Filter::CopyValue - copy the value from an other 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 value of the original field contains an invalid value (a value that will be constrained through a constraint) this invalid value will be choosen for this field (the field with CopyValue filter).

So the user has to change two fields or you remove the invalid value in a custom constraint.
