Change Default “Display Name Publicly As” for WordPress

Hi there,

Try this instead:

function db_display_current_user() {
    ob_start();
    $current_user = wp_get_current_user();

    if ( is_user_logged_in() ) {
        // Retrieve and display the user's first name and last name
        $first_name = $current_user->user_firstname;
        $last_name = $current_user->user_lastname;
        echo '<span class="current-user">' . $first_name . ' ' . $last_name . '</span>';
    } else {
        echo '<span class="current-user">Message for not logged in user</span>';
    }

    return ob_get_clean();
}

add_shortcode( 'current_user_name', 'db_display_current_user' );

No Problem 🙂
