how to register two attributes for default:shortcode_attr

Hi @jonny-s

In your page:

[contact-form-7 id="123" title="Contact Form" destination-email="[email protected]" destination-email2="[email protected]"]

In CF7:

[email* destination-email default:shortcode_attr]
[email* destination-email2 default:shortcode_attr]

In functions.php:

add_filter( 'shortcode_atts_wpcf7', 'custom_shortcode_atts_wpcf7_filter', 10, 3 );

function custom_shortcode_atts_wpcf7_filter( $out, $pairs, $atts ) {
	$my_attr = ['destination-email', 'destination-email2'];

	foreach ( $my_attr as $key => $value ) {
		if ( isset( $atts[$value] ) ) {
			$out[$value] = $atts[$value];
		}
	}

	return $out;
}

You’re welcome =)
