Add an image element for each post
Adds an image node to your RSS2 feeds
add_action( 'rss2_item', 'wporg_add_my_rss_node' ); function wporg_add_my_rss_node() { global $post; if ( has_post_thumbnail( $post->ID ) ) : $thumbnail = get_attachment_link( get_post_thumbnail_id( $post->ID ) ); echo "<image>{$thumbnail}</image>"; endif; }Feedback
The image block is per Feed, not per post/item. Feeds will not be validated if you use this code. Instead consider using Enclosure but to be valid it requires more details such as length and mime-type:
<enclosure url="http://example.com/file.mp3" length="123456789" type="audio/mpeg" />Please see W3 Schools article on RSS tag images for reference and example feed use. — By 5 Star Plugins —(From Codex)
Add a custom field element for each post
Adds a node from a custom field to your RSS2 feeds using get_post_meta().
Note: Custom elements like the one in this example are not a part of the RSS 2.0 specification, so adding it will mean your feed will technically be invalid RSS 2.0. Few, if any, RSS readers will make any use of the custom element.
<?php add_action('rss2_item', 'add_my_custom_field_node'); function add_my_custom_field_node() { global $post; $metaValue = get_post_meta($post->ID, 'my-custom-field', true); if(!empty($metaValue)): echo("<my-custom-field>{$metaValue}</my-custom-field>"); endif; } ?>
