Answers ( 1 )


    The get_tag_feed_link() function in WordPress is used to retrieve the permalink (URL) for a feed that corresponds to a specific tag. This function is useful for theme and plugin developers who need to provide links to tag-specific RSS feeds on their websites. Here's a detailed explanation and a sample usage of the function:

    Function Signature

    get_tag_feed_link( int|WP_Term|object $tag, string $feed = '' ): string

    Function Description

    • Purpose: Retrieves the permalink for a tag-specific feed.
    • Return Value: It returns a string that is the permalink for the given tag's feed.


    1. $tag (int|WP_Term|object, required): This parameter can be:

      • An integer representing the tag ID.
      • A WP_Term object.
      • Or a generic object representing a tag. This parameter specifies the tag for which the feed link is to be retrieved.
    2. $feed (string, optional): This parameter specifies the type of feed. Possible values include:

      • 'rss2': For RSS 2.0 feed.
      • 'atom': For Atom feed. If not specified, the default value is determined by the get_default_feed() function in WordPress.

    Default Value

    • Default for $feed: The default value is an empty string (''), which causes the function to use the default feed type set in WordPress (usually RSS 2.0).


    • Type: string
    • Description: The function returns the feed permalink URL for the specified tag.

    Sample Usage

    Here's an example of how get_tag_feed_link() can be used in a WordPress theme or plugin:

    // Assume you have a tag ID
    $tag_id = 123;
    // Retrieve the RSS feed link for this tag
    $rss_feed_link = get_tag_feed_link($tag_id, 'rss2');
    // Output the link (example usage in HTML)
    echo '<a href="' . esc_url($rss_feed_link) . '">Subscribe to RSS Feed for this Tag</a>';

    In this example, the function is used to get the RSS feed link for a tag with ID 123. The link is then output as part of an HTML anchor tag, providing users with a direct link to subscribe to the RSS feed for that specific tag.

    Important Notes

    • Always sanitize and escape URLs when outputting them in HTML to prevent XSS attacks.
    • This function is part of the WordPress template tag, which means it's used in theme files to generate dynamically updated links based on the tag.

    This function is a handy tool for customizing how users interact with tag-based content on a WordPress site, especially for those interested in following updates for specific topics or categories.
