Using Wordpress 3.9, I'm trying to create a custom feed template for a custom post type, which will include some custom fields.
Idea is to use this feed to to send out a "newsletter" type email once a month, with updates on newly added products.
The problem is that when I wanted to copy the code from the current feeds as a starting point for my custom feed, I couldn't find these pages anywhere.
According to the wordpress codex, these should be found within wp-includes. But they are not there. I checked a couple more folders... nothing.
Within wp-includes I do have a file called class.feed.php. But opening that really didn't give me any pointers.
I would need to remove the current custom post title from the field, as this is an empty field, and to add about 10 custom fields. So a completely new template seemed the easiest option.
wp-includes/feed-rss.php
orwp-includes/feed-rss2.php
