WooCommerce - Different shipping methods for recurring orders - php

Question

I am developing a site with the following plugins:
WooCommerce
WooCommerce Subscriptions
Pakkelabels.dk for WooCommerce
"Pakkelabels.dk" is a packaging label plugin for carriers in Denmark. This plugin is using the standard WooCommerce filters and hooks to add additional shipping methods.
I am using a mixed checkout. The cart totals currently looks like this:
This is what I wan't to do
For recurring orders I wan't to limit the shipping methods to just "DAO Pakkeshop" and "Local pick up" (sorry for the Danish language in the image).
I have added this to functions.php, which unsets the shipping methods I don't wan't to have, when a specific product ID (the subscription product) is in the cart:
add_filter( 'woocommerce_package_rates', 'hide_shipping_methods_woo_sg', 10, 2 );
function hide_shipping_methods_woo_sg( $rates, $package ) {
$product_id = get_field('product_auto_cart', 'option');
if($product_id){
$product_cart_id = WC()->cart->generate_cart_id( $product_id );
$in_cart = WC()->cart->find_product_in_cart( $product_cart_id );
if($in_cart) {
unset( $rates['pakkelabels_shipping_dao_direct'] );
unset( $rates['pakkelabels_shipping_gls_private'] );
unset( $rates['pakkelabels_shipping_gls_business'] );
unset( $rates['pakkelabels_shipping_gls'] );
unset( $rates['pakkelabels_shipping_pdk'] );
unset( $rates['pakkelabels_shipping_postnord_private'] );
unset( $rates['pakkelabels_shipping_postnord_business'] );
// unset( $rates['local_pickup:19'] );
}
return $rates;
}
}
My problem is, that this removes the shipping methods for both the order and recurring order, as you can see on the image.
I need some sort of conditional, so that I can target only the recurring order shipping methods and unset those.
How can I achieve this?

Answer 1

Okay - that was a simple fix. WC()->cart->recurring_carts was the conditional I needed. My code now looks like this:
add_filter( 'woocommerce_package_rates', 'hide_shipping_methods_woo_sg', 10, 2 );
function hide_shipping_methods_woo_sg( $rates, $package ) {
$product_id = get_field('product_auto_cart', 'option');
if($product_id){
$product_cart_id = WC()->cart->generate_cart_id( $product_id );
$in_cart = WC()->cart->find_product_in_cart( $product_cart_id );
if($in_cart && WC()->cart->recurring_carts) {
unset( $rates['pakkelabels_shipping_dao_direct'] );
unset( $rates['pakkelabels_shipping_gls_private'] );
unset( $rates['pakkelabels_shipping_gls_business'] );
unset( $rates['pakkelabels_shipping_gls'] );
unset( $rates['pakkelabels_shipping_pdk'] );
unset( $rates['pakkelabels_shipping_postnord_private'] );
unset( $rates['pakkelabels_shipping_postnord_business'] );
// unset( $rates['local_pickup:19'] );
}
return $rates;
}
}
The above shipping methods are now removed for recurring carts.
My cart totals now looks like this:
