WWW::Mechanize::FormFiller::Value::Callback(3)

NAME
WWW::Mechanize::FormFiller::Value::Callback - Call Perl code to fill out a HTML form field

SYNOPSIS
  use WWW::Mechanize::FormFiller;
  use WWW::Mechanize::FormFiller::Value::Callback;

  my $f = WWW::Mechanize::FormFiller->new();

  # Create a default value for the HTML field "login"
  # This will put the current login name into the login field

  sub find_login {
    getlogin || getpwuid($<) || "Kilroy";
  };

  my $login = WWW::Mechanize::FormFiller::Value::Callback->new( login => \&find_login );
  $f->add_value( login => $login );

  # Alternatively take the following shorthand, which adds the
  # field to the list as well :

  # "If there is no password, put a nice number there
  my $password = $f->add_filler( password => Callback => sub { int rand(90) + 10 } );
