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


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

the Rose::HTML::Form::Field::Email manpage is a subclass of the Rose::HTML::Form::Field::Text manpage that uses the Email::Valid manpage 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

Other examples of custom fields:

the Rose::HTML::Form::Field::Time manpage
Uses inflate/deflate to coerce input into a fixed format.

the Rose::HTML::Form::Field::DateTime manpage
Uses inflate/deflate to convert input to a DateTime object.

the Rose::HTML::Form::Field::DateTime::Range manpage
A compound field whose internal value consists of more than one object.

the Rose::HTML::Form::Field::PhoneNumber::US::Split manpage
A simple compound field that coalesces multiple subfields into a single value.

the Rose::HTML::Form::Field::DateTime::Split::MonthDayYear manpage

the Rose::HTML::Form::Field::DateTime::Split::MDYHMS manpage
A compound field that includes other compound fields and uses inflate/deflate convert input from multiple subfields into a DateTime object.
