Compatible with redirect User Role Code

The link that you posted is very far from what you want to achieve, but here is a snippet you can use in functions.php. It will change the redirect link used by Extra Settings for WooCommerce to shop link for active subscribers:

add_action( 'template_redirect', 'taisho_active_subscriptions', 999 );
function taisho_active_subscriptions () {
	add_filter( 'woocommerce_login_redirect', 'taisho_active_subscriber_user_redirect', 1000, 2 );
}
function taisho_active_subscriber_user_redirect( $redirect, $user ) {
	if ( wcs_user_has_subscription( '', '', 'active' ) ) {
		$shop_page_url = get_permalink( wc_get_page_id( 'shop' ) );
		$redirect = $shop_page_url;
	}
	return $redirect;
}

Thank you ??
