RSS feeds can be added to the Jupiter theme for all post types and can be used in different cases.
To add them, you’ll need to create a child theme first. For more information on how to create a child theme, click here.

In this article we’ll describe what an RSS feed is and how to add it to the Jupiter theme.


What Is an RSS Feed?

RSS stands for Rich Site Summary or Really Simple Syndication.
RSS feeds give your visitors a way to keep up with your website. Anyone can choose a site they wish to subscribe to, and then get updates in one location.
Instead of checking a site every day to see if it’s been updated, RSS feeds give users the ability to subscribe and read updates from the site, delivered via RSS feeds.


How RSS Feeds Work

RSS feeds are simple text files that allow subscribers to see content within a very short time after it’s been updated. RSS feeds can be read by using programs called RSS reader, feed reader, or aggregator. They can be web-based, desktop-based, and mobile-based.


How to Add an RSS Feed to the Jupiter Theme

1Create a child theme. Add a PHP file inside your child theme called functions.php

2Open up that file with a text editor and add the code below inside:

function request_allpost_types_feed($qv) {
if (isset($qv['feed']))
$qv['post_type'] = get_post_types();
return $qv;
}
add_filter('request', 'request_allpost_types_feed');

Instead of the post_type in the code, you’ll need to add the post type you’d like to have a feed in, for example, portfolio.

This way you’ll get an RSS feed on your portfolio page.
