Getting the RSS feed URL in WordPress with get_feed_link

The get_feed_link function is a feature provided by WordPress. Its primary purpose is to retrieve the URL for a given feed type associated with the current page or content. This function can be used to generate links for various types of feeds such as RSS, Atom, or RDF, depending on the feed type specified.

The use of the get_feed_link function can be beneficial in several situations. For instance, it can be used to provide users with a link to subscribe to your website’s content updates. When the function is invoked, it returns the URL for the specified feed type, which can then be used to create a clickable link for users to subscribe to the feed.

Another potential use of the get_feed_link function is for the purpose of web development and debugging. By using this function, developers can quickly and efficiently retrieve the URL for a specific feed type without having to manually construct the URL.

It’s important to note that the output of the get_feed_link function is affected by the settings and configurations of the WordPress site, and it may not always return a URL if the specified feed type is not supported or enabled on the site.

Parameters Accepted by the get_feed_link Function

The get_feed_link function in WordPress accepts a single parameter:

  • $feed (string) – This is an optional parameter. Its default value is an empty string (”). It specifies the type of feed. The possible values for this parameter are ‘rss2’, ‘atom’. If no value is provided, the function uses the value returned by get_default_feed() as the default.

Return Value of the get_feed_link Function

The get_feed_link function returns a string that represents the permalink of the feed.

If the function does not receive any parameters, it will still execute and return the default feed type.

Examples

How to Display the Link to the Site’s RSS Feed

In WordPress, you can use the get_feed_link function to retrieve the URL of the site’s RSS feed. Here’s an example of how to do this:

$rss_link = get_feed_link();
echo '<a href="' . esc_url($rss_link) . '">Subscribe to our RSS Feed</a>';

This code snippet gets the link to the site’s RSS feed using the get_feed_link function and assigns it to the $rss_link variable. It then outputs an HTML anchor tag with the RSS feed link as the href attribute, allowing users to subscribe to the site’s RSS feed.

How to Display the Link to the Site’s Atom Feed

Similarly, you can use the get_feed_link function to get the link to the site’s Atom feed:

$atom_link = get_feed_link('atom');
echo '<a href="' . esc_url($atom_link) . '">Subscribe to our Atom Feed</a>';

This code snippet gets the link to the site’s Atom feed by passing ‘atom’ as a parameter to the get_feed_link function. It then outputs an HTML anchor tag with the Atom feed link as the href attribute, allowing users to subscribe to the site’s Atom feed.

Conclusion

The get_feed_link function in WordPress is designed to retrieve the URL for a particular feed type. This function can be used in a variety of contexts, such as linking to RSS feeds, Atom feeds, or comment feeds.
