Rose::HTML::Form::Field::Email(3) User Contributed Perl Documentation Rose::HTML::Form::Field::Email(3)

Rose::HTML::Form::Field::Email - Text field that only accepts valid email addresses.

    $field =
      Rose::HTML::Form::Field::Email->new(
        label     => 'Email', 
        name      => 'email',
        size      => 30,
        maxlength => 255);

    if($field->validate)
    {
      $email = $field->internal_value;
    }
    else
    {
      # Handle invalid email addresses
    }

    print $field->html;

    ...

Rose::HTML::Form::Field::Email is a subclass of Rose::HTML::Form::Field::Text that uses Email::Valid to allow only valid email addresses as input. It overrides the validate() method of its parent class, returning true if the internal_value() is a valid email address, or setting an error message and returning false otherwise.

This is a good example of a custom field class that simply constrains the kinds of inputs that it accepts, but does not inflate/deflate values or aggregate other fields.

Other examples of custom fields:
Rose::HTML::Form::Field::Time
Uses inflate/deflate to coerce input into a fixed format.
Rose::HTML::Form::Field::DateTime
Uses inflate/deflate to convert input to a DateTime object.
Rose::HTML::Form::Field::DateTime::Range
A compound field whose internal value consists of more than one object.
Rose::HTML::Form::Field::PhoneNumber::US::Split
A simple compound field that coalesces multiple subfields into a single value.
Rose::HTML::Form::Field::DateTime::Split::MonthDayYear
A compound field that uses inflate/deflate convert input from multiple subfields into a DateTime object.
Rose::HTML::Form::Field::DateTime::Split::MDYHMS
A compound field that includes other compound fields and uses inflate/deflate convert input from multiple subfields into a DateTime object.
