Add order note to new customer orders in WooCommerce - php

Question

I'm trying to add in a feature where an admin order note will be added for all first time customers.
The code I am trying is:
add_action('woocommerce_thankyou', 'is_returning_customer', 10, 1);
function is_returning_customer($order_id)
{
if (!$order_id) {
return;
}
if(is_user_logged_in()) {
$order_status = array('wc-on-hold,','wc-processing', 'wc-completed');
$customer_id = get_current_user_id();
$customer_orders=get_posts( array(
'meta_key' => '_customer_user',
'meta_value' => $customer_id,
'post_type' => 'shop_order',
'post_status' => $order_status,
'numberposts' => -1
)
);
}
if (count($customer_orders) => 1) {
$order = wc_get_order( $order_id );
$note = '*** New Customer ***';
$order->add_order_note($note);
$order->save();
}
}
However, the problem it's adding the new customer note on every order. Any advice?

Your code looks fine except for syntax errors here. I revised your code. try the below code.
Changed
if (count($customer_orders) => 1) {
To
if (count($customer_orders) >= 1) {
Changed
$order_status = array( 'wc-on-hold,','wc-processing', 'wc-completed' );
To
$order_status = array( 'wc-on-hold', 'wc-processing', 'wc-completed' );
for check customer is first time trying below condition.
if ( count( $customer_orders ) < 1 ) {
for check customer is a return. try the below condition.
if ( count( $customer_orders ) > 0 ) {
Complete code. for returning customer
function is_returning_customer( $order_id ) {
if ( !$order_id ) {
return;
}
if( is_user_logged_in() ) {
$order_status = array( 'wc-on-hold,','wc-processing', 'wc-completed' );
$customer_id = get_current_user_id();
$customer_orders = get_posts( array(
'meta_key' => '_customer_user',
'meta_value' => $customer_id,
'post_type' => 'shop_order',
'post_status' => $order_status,
'numberposts' => -1
)
);
}
if ( count( $customer_orders ) > 0 ) {
$order = wc_get_order( $order_id );
$note = '*** New Customer ***';
$order->add_order_note($note);
$order->save();
}
}
add_action( 'woocommerce_thankyou', 'is_returning_customer', 10, 1 );

$customer_id = get_current_user_id();

}

$order->add_order_note($note);
$order->save();
}
}
add_action( 'woocommerce_thankyou', 'is_first_time_customer', 10, 1 );

Actually it is not necessary to go through the orders, as there is already a function for this in WooCommerce, namely wc_get_customer_order_count() - Get total orders by customer.
Only the issue here is, just like with your current code, that this would only work for logged in users.
To make this also work for 'guests' you can use the following:
function action_woocommerce_thankyou( $order_id ) {
// Get $order object
$order = wc_get_order( $order_id );
// Is a WC_Order
if ( is_a( $order, 'WC_Order' ) ) {
// Get user id
$user_id = $order->get_user_id();
// Set variable
$count = 0;
// Not a guest
if ( $user_id > 0 ) {
// Get the total orders by a customer.
$count = wc_get_customer_order_count( $user_id );
} else {
// Guest 'user', don't have a user id so we will determine the previous orders based on the billing email
// Get billing email
$billing_email = $order->get_billing_email();
if ( ! empty ( $billing_email ) ) {
// Call function
$count = has_guest_bought_by_email( $billing_email );
}
}
// Output
if ( $count == 1 ) {
$note = '** New Customer **';
$order->add_order_note( $note );
}
}
}
add_action( 'woocommerce_thankyou', 'action_woocommerce_thankyou', 10, 1 );
// Based on https://stackoverflow.com/a/46216073/11987538
function has_guest_bought_by_email( $email ) {
global $wpdb;
// Get all order statuses.
$order_statuses = array_map( 'esc_sql', array_keys( wc_get_order_statuses() ) );
$results = $wpdb->get_col( "
SELECT p.ID FROM {$wpdb->prefix}posts AS p
INNER JOIN {$wpdb->prefix}postmeta AS pm ON p.ID = pm.post_id
WHERE p.post_status IN ( '" . implode( "','", $order_statuses ) . "' )
AND p.post_type LIKE 'shop_order'
AND pm.meta_key = '_billing_email'
AND pm.meta_value = '$email'
" );
// Return result
return count( $results );
}
