How to get "Vendor Email Address" using "$order_id" (WooCommerce) - wordpress

Question

I have created a custom plugin to send an email to vendor when "new order received". Here I have used "YITH WooCommerce Multi Vendor / Marketplace" plugin to manage the vendors.
function send_vendor_notification( $order_id ) {
$order = wc_get_order( $order_id );
$items = $order->get_items();
foreach ( $items as $item ) {
$product_name = $item['name'];
$product_id = $item['product_id'];
$product_variation_id = $item['variation_id'];
}
$vendor_email = "dilshanudawatta15#gmail.com";
$subject = 'New Order Received';
$message = 'You have received a new order (#' . $order_id . '). Product
Name : (#' . $product_name . ') Product ID : (#'. $product_id .').';
wp_mail( $vendor_email, $subject, $message );
}
add_action( 'woocommerce_thankyou', 'send_vendor_notification' );
This is my function to send an email to vendor. Here I have hardcoded the $vendor_email. This function is working. But I want to find a way to access $vendor_email using $order_id. Woocommerce REST API has not a endpoint to directly access vendor details from latest order.
Can I use "yith_get_vendor" for this? and Is there any easy way to access the vendor email using order id?

Answer 1

If you have the $order_id, you can get access to the vendor's email like this:
$order = wc_get_order( $order_id );
$vendor_id = yith_get_vendor( $order_id, 'vendor' )->id;
$vendor = get_wcmp_vendor( $vendor_id );
$vendor_email = $vendor->user_data->user_email;
echo $vendor_email;
First, you fetch the $order object and then the $vendor_id. Then you can use that id to get the $vendor object and it's email.
