Answers ( 1 )


    The get_comment_author_rss() function in WordPress is used primarily within the context of RSS feeds. This function retrieves the name of the author of a comment, which is then typically used in the RSS feed to show who commented on a post. The function is straightforward and returns a string value, which is the name of the comment author.

    Here's a detailed explanation and a sample usage:


    get_comment_author_rss(): string


    • Retrieves the Current Comment Author for Use in the Feeds: This function is specifically designed to fetch the name of the author of a comment. Its primary use is within RSS feeds, where it's important to display who has commented on a post.


    • Type: string
    • Description: The function returns the name of the comment author as a string.

    Sample Usage:

    Here's a simple example of how get_comment_author_rss() might be used in a WordPress theme or plugin, particularly when customizing RSS feed templates:

    if ( have_comments() ) {
        foreach ( $comments as $comment ) {
            echo '<item>';
            echo '<title>' . get_the_title() . '</title>';
            echo '<link>' . get_comment_link() . '</link>';
            echo '<dc:creator>' . get_comment_author_rss() . '</dc:creator>';
            echo '<description>' . get_comment_text() . '</description>';
            echo '</item>';

    In this snippet:

    • The code checks if there are any comments on the post using have_comments().
    • It then iterates over each comment.
    • For each comment, it creates an RSS item.
    • get_comment_author_rss() is used to retrieve the name of the comment's author, which is included in the <dc:creator> tag.

    Important Notes:

    • Context of Use: This function is typically used only in RSS feed templates or contexts where you're dealing with comment data in a feed format.
    • Escaping Output: Depending on your theme or plugin's context, consider escaping the output of get_comment_author_rss() for security, using functions like esc_html().

    By using get_comment_author_rss(), WordPress theme and plugin developers can easily display comment author names in RSS feeds, adding a personal touch and clarity on who is engaging with content.
