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 } );

DESCRIPTION

       This class provides a way to write a value returned by Perl code into a HTML field.

       new NAME, CODE
           Creates a new value which will correspond to the HTML field "NAME". The "CODE" is a
           code reference that will return the value to be written into the HTML field.  The code
           reference will be called with two parameters, the object and the HTML::Form::Input
           object.

       name [NEWNAME]
           Gets and sets the name of the HTML field this value corresponds to.

       value FIELD
           Returns the value to put into the HTML field.

   EXPORT
       None by default.
