=head1 NAME

HTML::FormHandler::Field::Text - text field

=head1 VERSION

version 0.40057

=head1 DESCRIPTION

This is a simple text entry field. Widget type is 'text'.

=head1 METHODS

=head2 size [integer]

This is used in constructing HTML. It determines the size of the input field.
The 'maxlength' field should be used as a constraint on the size of the field,
not this attribute.

=head2 minlength [integer]

This integer value, if non-zero, defines the minimum number of characters that must
be entered.

=head2 maxlength [integer]

A constraint on the maximum length of the text.

=head2 error messages

Set error messages (text_minlength, text_maxlength):

    has_field 'my_text' => ( type => 'Text', messages =>
        {  'text_minlength' => 'Field is too short',
           'text_maxlength' => 'Field is too long',
        } );
