How to use post_comments_feed_link_html filter in WordPress

Let’s dive into the world of WordPress hooks! Today, we’re talking about the post_comments_feed_link_html filter. This hook is all about filtering the post comment feed link anchor tag. Now, before you get started, you need to register it using add_filter. You can place this code in the functions.php of your active theme or in a custom WordPress Plugin. Personally, I prefer creating a custom Plugin, so nothing breaks when you update your WordPress theme. Let’s move on to some live examples!

Example 1: Modifying Default Comment Feed Link

In this example, we’ll define a function called weplugins_modify_post_comments_feed_link_html_defaults that takes three parameters. We then register it using add_filter with the hook name, function name, priority, and number of arguments.

    function weplugins_modify_post_comments_feed_link_html_defaults($link, $post_id, $feed) { 
        // Update the $link variable according to your website requirements and return this variable.
        return $link; 
    }
    // add the filter
    add_filter( "post_comments_feed_link_html", "weplugins_modify_post_comments_feed_link_html_defaults", 10, 3 );
    

Example 2: Applying the Hook

Here’s how you can apply this hook. It filters the anchor tag for the comment feed link, and you can modify its output based on your requirements.

    apply_filters( 'post_comments_feed_link_html', string $link, int $post_id, string $feed );
    

Example 3: Removing the Hook

Sometime, you might need to remove a registered hook. Use remove_filter to remove the post_comments_feed_link_html filter. Ensure you provide the same callback function name, priority, and number of arguments.

    remove_filter( "post_comments_feed_link_html", "weplugins_modify_post_comments_feed_link_html_defaults", 10, 3 );
