Adding “figure” and “figcaption” markup?

Hi @cconstantine you can use the same RSS hooks we use, is_feed(), has_post_thumbnail(), get_the_post_thumbnail(), etc.

For example:

function add_figure_to_rss_content($content) {
    if (is_feed()) {
        global $post;
        
        // Check for a featured image
        if (has_post_thumbnail($post->ID)) {
            // Get the featured image HTML
            $thumbnail_html = get_the_post_thumbnail($post->ID, 'large');
            
            // Optionally add caption or figcaption if you like:
            $caption = get_post(get_post_thumbnail_id())->post_excerpt;
            $figcaption_html = $caption ? "<figcaption>" . esc_html($caption) . "</figcaption>" : "";
            
            // Wrap in <figure>
            $figure_html = "<figure>{$thumbnail_html}{$figcaption_html}</figure>";
            
            // Prepend or append to the content
            $content = $figure_html . $content;
        }
    }
    return $content;
}
add_filter('the_content_feed', 'add_figure_to_rss_content');

We may be able to add this option to our plugin, so it’s a simple checkbox. We’ll evaluate this and see if it’s something we’d want to add in a future update.
