HTML5 attributes

Each form element is created by extending the MW_Form_Field class.
There are real each form element in MW_Form class but there are not input=”tel” in MW_Form class. So you need to create your own.

For example :

function add_tel_field() {
    include_once ' ./form_field_tel.php;
    new Form_Field_Tel();
}
add_action( 'plugins_loaded', 'add_tel_field' );

* field_tel.php
class Form_Field_Tel extends MW_Form_Field {
    ...
    protected function inputPage() {
        ...
        return sprintf( '<input type="tel" name="%s" value="%s" />, ... )
    }
    ...
}

Thanks, Takashi.

I will extend MW_Form_Field class.
