How to use pre_get_avatar filter in WordPress

pre_get_avatar filter is a handy tool when you want to customize the avatar display in WordPress. This filter lets you short-circuit the get_avatar() function, allowing you to have more control over avatar output. It’s like giving your site a personal touch! To use this filter, you’ll need to register it using add_filter. You can add this code to your theme’s functions.php file or even better, create a custom WordPress plugin for it. At WePlugins, we always recommend using a custom plugin to keep your changes safe during theme updates.

Live Example 1: Modifying Avatar Output

Here’s an example of how you can use the pre_get_avatar filter to modify the default avatar output.

        function weplugins_modify_pre_get_avatar_defaults($avatar, $id_or_email, $args) { 
            // Customize $avatar as per your website's needs
            return $avatar; 
        }
        // add the filter
        add_filter( "pre_get_avatar", "weplugins_modify_pre_get_avatar_defaults", 10, 3 );
        

Live Example 2: Conditional Avatar Modification

Sometimes, you may want to modify the avatar only under specific conditions. Here’s how you can do it:

        function weplugins_conditional_avatar($avatar, $id_or_email, $args) { 
            if (is_user_logged_in()) {
                // Modify $avatar for logged-in users
            }
            return $avatar; 
        }
        add_filter( "pre_get_avatar", "weplugins_conditional_avatar", 10, 3 );
        

Live Example 3: Removing a Filter

If you need to remove a previously added filter, here’s an example:

        remove_filter( "pre_get_avatar", "weplugins_modify_pre_get_avatar_defaults", 10, 3 );
        

Remember to use the exact callback function name, priority, and arguments when removing a hook.
