NAME ^

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

SYNOPSIS ^

    $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;

    ...

DESCRIPTION ^

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.

SEE ALSO ^
