Function and usage of get_category_feed_link() in wordpress


Answers ( 1 )


    The get_category_feed_link() function in WordPress is used to retrieve the feed link for a specific category. This function is particularly useful if you want to provide a direct link to a feed that contains only posts from a certain category, which can be helpful for users who want to subscribe to content related to a specific topic.

    Function Signature

    get_category_feed_link( int|WP_Term|object $cat, string $feed = '' ): string


    • Purpose: The function returns a link to the feed for all posts in a given category. You can request a specific type of feed (like RSS2 or Atom) or use the default feed type.
    • Use Case: Useful for creating custom links on a website that allow users to subscribe to category-specific content.


    1. $cat (int|WP_Term|object) (Required): This parameter accepts either the ID of the category or a category object. It specifies which category's feed link you want to retrieve.

    2. $feed (string) (Optional): This parameter defines the type of feed to retrieve. Possible values are:

      • 'rss2': For RSS2 feed type.
      • 'atom': For Atom feed type.
      • If left blank (''), it defaults to the value returned by get_default_feed(), which typically returns 'rss2'.

    Return Value

    • Type: string
    • Description: The function returns the URL as a string. This URL is the link to the feed for the category specified by $cat.

    Sample Usage

    Here's an example of how you might use get_category_feed_link() in a WordPress template:

    $category_id = 5; // Assume this is the category ID for which you want the feed link
    $feed_type = 'rss2'; // Specify the feed type; 'rss2' or 'atom'
    // Get the feed link
    $category_feed_link = get_category_feed_link($category_id, $feed_type);
    // Output the feed link
    echo 'Subscribe to this category: <a href="' . esc_url($category_feed_link) . '">RSS Feed</a>';

    In this example, we're retrieving the RSS2 feed link for category ID 5 and then creating an anchor tag to allow users to subscribe to this category's feed. The esc_url() function is used to escape the URL for safe output in HTML.
