Rewrite custom post type rss feed links

Question

I am looking for a way to rewrite my custom post type feed located at

http://localhost:8888/feed/?post_type=post

to

http://localhost:8888/feed/portfolio

this post suggests using

http://localhost:8888/portfolio/feed/

which is not the main feed but the comments feed, any ideas?

http://localhost:8888/portfolio/feed

currently the above goes to comments as well.

Answer 1

Put this in a plugin or functions.php:

function feed_rewrite( $wp_rewrite ) {

    $feed_rules = array(
        'feed/portfolio'    =>  'index.php?post_type=post&feed=rss2'
    );

    $wp_rewrite->rules = $feed_rules + $wp_rewrite->rules;
}
// refresh/flush permalinks in the dashboard if this is changed in any way
add_filter( 'generate_rewrite_rules', 'feed_rewrite' );

When you've done that, go to the permalinks page and resave to flush your old rules and regenerate them

Remember, when changing rewrite rules to use the monkeyman rewrite analyser tool plugin to check what rules are used for which URLs

Answer 2

If you have the archive on CPT to true, that creat WP always a feed, the nice URL is only usable, after you refresh the permalinks via Settings in Backend or via a function in your code. Important is the name of your CPT, should the name is "portfolio". If you have another name, then you must create a rewrite, maybe with wp_rewrite() or via rules inside the .htaccess File, if it is a a Apache server.
