Woocommerce login

if ( ! is_user_logged_in() ) {
    $redirect_to = wp_login_url();
    redirect( $redirect_to );
    exit;
}

Thank you.
Is that the code to insert to template files?
I prefer to use a hook.

How about this?

function my_wc_loginpage(){
  if(!is_user_logged_in() && (is_account_page() || is_checkout())){
    $redirect_to = wp_login_url(); wp_redirect( $redirect_to ); exit;
  }
}
add_action('template_redirect','my_wc_loginpage');

It’s nice if ThemeMyLogin have this ability by default.

That will work!
