Disable the admin bar for all users except admin

Question

I have installed WordPress and BudyPress. I want to disable the admin bar which appears on the top for all users.

Can somebody tell me how to do that correctly?

Answer 1

function is_current_user_administrator() {
    global $current_user;

    return !in_array( 'administrator', $current_user->roles );
}

add_filter( 'show_admin_bar', 'is_current_user_administrator' );
