How to use get_comment_author_url filter in WordPress

get_comment_author_url filter

The get_comment_author_url filter is used to modify the comment author’s URL. To use it, you’ll first need to register it using add_filter. You can place this code in the functions.php file of your active theme or create a custom WordPress plugin. At WePlugins, we always recommend creating a custom plugin to ensure your changes are preserved during theme updates.

Example 1: Basic Usage

This example shows how to apply the get_comment_author_url filter to modify the comment author’s URL.

    function weplugins_modify_get_comment_author_url($url, $comment_ID, $comment) {
        // Modify the URL as needed
        return $url;
    }
    add_filter('get_comment_author_url', 'weplugins_modify_get_comment_author_url', 10, 3);
    

Example 2: Conditional URL Modification

Here, the URL is modified based on a condition, showcasing the flexibility of this hook.

    function weplugins_modify_comment_url_conditionally($url, $comment_ID, $comment) {
        if ($comment_ID % 2 == 0) { 
            $url = 'https://example.com/author/even';
        }
        return $url;
    }
    add_filter('get_comment_author_url', 'weplugins_modify_comment_url_conditionally', 10, 3);
    

Example 3: Removing the Hook

If you need to remove a previously registered filter, use remove_filter as shown below.

    remove_filter('get_comment_author_url', 'weplugins_modify_get_comment_author_url', 10, 3);
    

Ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.

• $url: (string) The comment author’s URL, or an empty string.
