How to use get_avatar filter in WordPress

Let’s dive into the world of WordPress hooks with a focus on the get_avatar filter. This filter lets you modify the HTML for a user’s avatar. You can easily implement this by registering the hook using add_filter. It’s always a good practice to do this in a custom WordPress Plugin to prevent disruptions during theme updates.

Example 1: Basic Usage of get_avatar Filter

Here’s a simple example to see how you can utilize the get_avatar filter in your WordPress site.

    function weplugins_modify_get_avatar_defaults($avatar, $id_or_email, $size, $default, $alt, $args) {
        // Update avatar according to your requirements
        return $avatar; 
    }
    // add the filter
    add_filter("get_avatar", "weplugins_modify_get_avatar_defaults", 10, 6);
    

Example 2: Removing the get_avatar Hook

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

    remove_filter("get_avatar", "weplugins_modify_get_avatar_defaults", 10, 6);
    

It’s important to use the same callback function name, priority, and number of arguments when removing the hook.

Example 3: Advanced Avatar Customization

In this example, we’ll demonstrate a more advanced customization of the avatar display, using conditional logic.

    function weplugins_advanced_avatar_customization($avatar, $id_or_email, $size, $default, $alt, $args) {
        // Check user type or other conditions
        if (is_numeric($id_or_email)) {
            $user = get_user_by('id', (int)$id_or_email);
            // Modify avatar based on user type
        }
        return $avatar;
    }
    add_filter("get_avatar", "weplugins_advanced_avatar_customization", 10, 6);
