I’m wondering if anyone has any ideas on how to add a custom field to a post’s RSS feed?
Much appreciated!
That would depend on how you want to modify the feeds. If you’re happy with adding the content of these feeds to the content area of the feed, then this will be helpful http://www.paulund.co.uk/add-custom-fields-to-rss-feed.
If you want to modify the feed in some other way then I suggest you look at this https://codex.wordpress.org/Customizing_Feeds
