Get the product ID in WooCommerce 3+ Order items - php

Question

I am trying to get woocommerce thank you page order_id. Using the code below.
But unfortunately I can't get it.
add_action( 'woocommerce_thankyou', 'bbloomer_check_order_product_id');
function bbloomer_check_order_product_id( $order_id ){
$order = new WC_Order( $order_id );
$items = $order->get_items();
foreach ( $items as $item ) {
$product_id = $item['product_id'];
if ( $product_id == XYZ ) {
// do something
}
}
}

Answer 1

This code is outdated for WooCommerce version 3+. You should use instead:
add_action( 'woocommerce_thankyou', 'check_order_product_id', 10, 1);
function check_order_product_id( $order_id ){
# Get an instance of WC_Order object
$order = wc_get_order( $order_id );
# Iterating through each order items (WC_Order_Item_Product objects in WC 3+)
foreach ( $order->get_items() as $item_id => $item_values ) {
// Product_id
$product_id = $item_values->get_product_id();
// OR the Product id from the item data
$item_data = $item_values->get_data();
$product_id = $item_data['product_id'];
# Targeting a defined product ID
if ( $product_id == 326 ) {
// do something
}
}
}
Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
This code is tested and works for WooCommerce version 3+

I was not satisfied with current answers, as sometimes you need to check multiple products. If you do the same search for each product, it's really a waste, so I put it into a dispatcher format.
add_action('woocommerce_order_status_completed', 'onItemCheckout',10,1);
function onItemCheckout($order_id){
$order = wc_get_order($order_id);
foreach ($order->get_items() as $item_key => $item_values){
$product_id = $item_values->get_product_id();
switch($item_values->get_product_id()){
case 9999 : FreeShipping($order, $product_id); break;
case 1010 : RequireValidation($order, $product_id); break;
default: break;
}
}
}
Alternatively,...
$ItemCheckoutHandler=[];
$ItemCheckoutHandler[9999]='FreeShipping';
$ItemCheckoutHandler[1010]='RequireValidation';
add_action('woocommerce_order_status_completed', 'onItemCheckout',10,1);
function onItemCheckout($order_id){
global $ItemCheckoutHandler;
$order = wc_get_order($order_id);
foreach ($order->get_items() as $item_key => $item_values){
$product_id=$item_values->get_product_id();
$ItemCheckoutHandler[ $product_id ]( $order, $product_id );
} //Call the function assigned to that product id in the array
}
In either case, the assigned functions would take the order object, rather than the id, and the product_id as an argument:
function FreeShipping($order, $product_id){ ... }
function RequireValidation($order, $product_id){ ... }
You can of course customize these inputs to your liking.

Try this, hope it will work
add_action( 'woocommerce_thankyou', 'your_function_name', 10);
function your_function_name($order_id)
{
$order = wc_get_order($order_id);
foreach($order->get_items() as $order_key => $order_value)
{
$product_id = $order_value->get_data()['product_id'];
if($product_id == '123')
{
//do what you wnat and 123 is random product id, you can match product id with other as you want
}
}
}
Thank you.
