WordPress/WooCommerce: Save custom payment post meta - php

Question

I am using a plugin that is creating a custom payment type where the user can fill in a custom payment ID. The thing is, I want that custom payment ID stored in an ACF field as post meta on the WooCommerce order edit page. I have created an ACF field named 'kkpayment' for this task. I figured the rest should be done using update_field($selector, $value, [$post_id]);. I have created a PHP function for this task. However, my code doesn't seem to work. Am I missing something obvious?
My function for updating the ACF field:
add_action( 'woocommerce_checkout_update_order_meta', 'custom_payment_update_order_meta_acf' );
function custom_payment_update_order_meta_acf( $order_id ) {
$transaction = get_post_meta( $order->id, 'transaction', true );
if($_POST['payment_method'] = 'custom')
return $transaction;
update_field('kkpayment', $transaction, $order_id);
}
The custom payment is made with this code:
<?php

Answer 1

Use this code to update acf field on successful transaction.
add_action( 'woocommerce_thankyou', 'bks_post_transaction_after_order_completion', 10, 1 );
function bks_post_transaction_after_order_completion( $order_id ) {
$order = wc_get_order( $order_id ); // phpcs:ignore.
$status = $order->get_status();
// Try to post only when order status is completed or processing.
if ( ! ( 'completed' === $status || 'processing' === $status ) ) {
return;
}
// get transaction.
$transaction = get_post_meta( $order->id, 'transaction', true );
update_field('kkpayment', $transaction, $order_id);
$order->update_meta_data( 'kkpayment', $transaction ); // phpcs:ignore
$order->save();
}
