Change user role based on WooCommerce yearly orders count - php

Question

I'm trying to implement a feature where customers receive a new user role after a certain amount of orders have been made, but all those orders must have been made within the same year.
I was able to assign the user role based on nth number of orders but can't seem to go beyond to where the date needs to be taken into consideration, can someone point me in the right direction or point out what I might be missing.
This is what I have tried so far.
function change_user_role_on_order_status_completed( $order_id ) {
$order = new WC_Order( $order_id );
$user_id = $order->user_id;
$order_this_year = false;
$current_date = date('Y');
$total_orders = get_posts( array(
'numberposts' => -1,
'meta_key' => '_customer_user',
'meta_value' => $user_id,
'post_type' => 'shop_order',
) );
if ( $total_orders > 1 ) {
foreach ($order->get_items() as $item_key => $item_values):
// Get the item date
if ($item_date = $item_values->get_date_completed()->format ('Y') == $current_date) {
$order_this_year = true;
}
endforeach;
if ($order_this_year) {
$user = new WP_User( $order->user_id );
// Set role editor
$user->set_role( 'customer_club' );
}
}
}
add_action( 'woocommerce_order_status_completed', 'change_user_role_on_order_status_completed', 10, 1 );

Answer 1

Using WC_Order_Query here is a much lighter and simple way to change the user role based on yearly orders count:
add_action( 'woocommerce_order_status_completed', 'change_user_role_on_order_status_completed', 10, 2 );
function change_user_role_on_order_status_completed( $order_id, $order ) {
// Here set the minimal order count
$min_orders_count = 3;
// The WC_Order_Query
$queried_orders = wc_get_orders( array(
'limit' => -1,
'customer_id' => $order->get_customer_id(),
'date_paid' => '>=' . date('Y') . '-01-01', // or 'date_created'
'return' => 'ids'
) );
if ( sizeof($queried_orders) >= $min_orders_count ) {
// Get an instance of the customer WP_User Object
$user = $order->get_user();
// Change the user role
$user->set_role( 'customer_club' );
}
}
Code goes in function.php file of your active child theme (or active theme). Tested and works.
