Wordpress RSS File Template

Question

I need to add some code to my RSS feeds, so I am searching for the RSS Feed .php file so I can add my code. Any help in finding this template file would be greatly appreciated.

Answer 1

To add some tags to the rss2 feed you may use the 3 action hooks that can be found in the wp-includes/feed-rss2.php

rss2_ns : to add a specific namespace

rss2_head : to add tags in the feed header

rss2_item : to add tags in each feed items

For example, let's assume you want to add a copyright in your feed's header using the dublin core vocabulary :

function my_rss2_head(){
    echo '<dc:rights>&copy; '.bloginfo_rss('name').'</dc:rights>'.PHP_EOL;
}
add_action( 'rss2_head', 'my_rss2_head');

Answer 2

Feed templates are in wp-includes folder, files starting with feed-. As rest of the WordPress core they are not supposed to be modified.

You will need to:

1. Determine type of feed you want to modify (usually default RSS 2.0 one).
2. Unhook native function that loads feed template, for example remove_action('do_feed_rss2','do_feed_rss2');
3. Create your own feed template.
4. Create and hook your own function that will load your template, by analogue with do_feed_rss2() ( source ).

Alternatively you can use some specific hooks in feed template to add what you want.

Update

As per Otto's comment steps 2 and 4 can be simplified using add_feed() function ( source ).
