Works perfectly!

Thanks for the prompt response.

So this is the function I have for my above code:

add_filter( 'mt_handle_custom_cart_data', 'my_save_custom_field', 10, 2 );
function my_save_custom_field( $payment, $post ) {
	update_post_meta( $payment, '_tag', $_POST['tag'] );
	update_post_meta( $payment, '_country', $_POST['country'] );
}

add_filter( 'mt_show_in_payment_fields', 'my_show_custom_field', 10, 2 );
function my_show_custom_field( $output, $post_ID ) {
	$tag = get_post_meta( $post_ID, '_tag' );
	$country = get_post_meta( $post_ID, '_country' );
	return $output . $tag . $country;
}

As far as I can find, the input data is still not showing anywhere. I must be doing something wrong here.

Thanks for the prompt reply.

I tried modifying the filter and function to fit my code but for some reason I cannot get it to work. I also tried using {tag} in emails, but it also does not display the inserted value. Can you help giving me an example code that works with a text input type?

Thanks.
