WooCommerce Subscriptions hook: Get Order Items - php

Question

WooCommerce 3.0 broke my app and I cannot figure out how to fix it now.
I have an action for when a subscription is added/changed running here:
Inside the function I was getting the order details and finding the line item for a variable subscription to update my custom DB with the option as well as getting custom order meta that I added via woocommerce_form_field:
This no longer works and everything appears protected? How can I update this to work with 3.0?
add_action( 'woocommerce_subscription_status_changed', 'update_subscription', 10, 3 );
function update_subscription( $id, $old_status, $new_status ) {
$sitelink_db = new SSLA_DB_Sitelink();
$order = new WC_Order( $id );
$items = $order->get_items();
$subscription_type = '';
$user_id = $order->get_user_id();
$sitelink_domain = get_post_meta( $order->id, 'ssla_sitelink_url', true );
foreach ($items as $item) {
if( "SiteLink Subscription" === $item['name'] ) {
$subscription_type = $item['brand'];
}
}
$customer_data = array(
'user_id' => $user_id,
'subscription_type' => $subscription_type,
'domain_referrer' => $sitelink_domain,
'active_subscription' => $new_status,
'date_modified' => date( 'Y-m-d H:i:s' ),
);
$sitelink_db->add( $customer_data );
}
Basically I need to get that variation name of the subscription to store in my DB, as well as that custom meta field I made. Which does not work anymore either

Answer 1

Here's my best guess. It's impossible to test since I don't have the same setup as you.
Few notes:
The $subscription object is passed to the woocommerce_subscription_status_changed hook so let's use it.
$order->id should be replaced by $order->get_id() in WC3.0, but we're going to use the the $subscription object (the subscription order class extends the order class so it's similar).
getters must be used on the WC_Order_Item_Product object that is returned when looping through get_items() so $item['name'] becomes $item->get_name()
Here's the full code block:
add_action( 'woocommerce_subscription_status_changed', 'update_subscription', 10, 4 );
function update_subscription( $subscription_id, $old_status, $new_status, $subscription ) {
$match_this_id = 99; // Change this to the product ID of your special subscription
$sitelink_db = new SSLA_DB_Sitelink();
$items = $subscription->get_items();
$subscription_type = '';
$user_id = $subscription->get_user_id();
$sitelink_domain = $subscription->get_meta( 'ssla_sitelink_url' );
foreach ($items as $item) {
if( $match_this_id === $item->get_product_id() ) {
$product = $item->get_product();
if( $product->is_type( 'variation' ) ){
$subscription_type = $product->get_attribute( 'brand' );
}
}
}
$customer_data = array(
'user_id' => $user_id,
'subscription_type' => $subscription_type,
'domain_referrer' => $sitelink_domain,
'active_subscription' => $new_status,
'date_modified' => date( 'Y-m-d H:i:s' ),
);
$sitelink_db->add( $customer_data );
}
