Personalise contact message

Hi,
by default in the [adverts_add] form, there is a “Contact Person” field, if you have not removed it then you can use it in the email template like this {$advert|meta:adverts_person}.

If you prefer to use the display name saved in the wp-admin / Users then you would need to first register a function that will be able to do it.

That is, first add the code below in your theme functions.php file

function get_user_display_name( $user_id ) {
  return get_user_by( 'id', $user_id )->display_name;
}

then in the email template you should be able to use the following syntax {$advert.post_author|get_user_display_name}.
