Recently I was working on a WordPress site and wanted to add a custom node to the WordPress RSS Feeds. In my previous post How to add featured image to WordPress RSS feed<\/a> we saw how to add a featured image to the post content in RSS Feed. In this post we will see how we can add any node to the RSS Feed. To add a custom node in the RSS feed we just need to add some code to the theme’s functions.php file.
\n<\/p>\n

Important<\/strong>: Make sure to add the code to the functions.php file of your theme. Do not add it to the functions.php file in the wp-includes directory.<\/p>\n

Here is an example code that you can add to the theme’s functions.php file to add the featured image as a node in the RSS Feed. <\/p>\n

\r\n\/\/ Add the image node to RSS feed\r\nfunction add_rss_node_image() {\r\n\tglobal $post;\r\n\tif(has_post_thumbnail($post->ID)):\r\n\t\t$thumbnail = get_attachment_link(get_post_thumbnail_id($post->ID));\r\n\t\techo "<image>{$thumbnail}<\/image>";\r\n\tendif;\r\n}\r\n\r\nadd_action('rss2_item', 'add_rss_node_image');\r\n<\/pre>\n
The above example add the featured image URL in the image node like this <image>featured_image_url<\/image><\/code>. You can add any custom nodes to the RSS Feed. <\/p>\n
Here is an example to add the image and thumbnail nodes.<\/p>\n
\r\n\/\/ Add the image and thumbnail node to RSS feed\r\nfunction add_rss_node_image_thumbnail() {\r\n\tglobal $post;\r\n\tif (has_post_thumbnail($post->ID)):\r\n\t\t$image = wp_get_attachment_url(get_post_thumbnail_id($post->ID));\r\n\t\t$thumbnail = wp_get_attachment_thumb_url(get_post_thumbnail_id($post->ID));\r\n\t\techo "<image>{$image}<\/image>\r\n\t\t<thumbnail>{$thumbnail}<\/thumbnail>";\r\n\tendif;\r\n}\r\nadd_action('rss2_item', 'add_rss_node_image_thumbnail');\r\n<\/pre>\n
