Add Tracking Code to WooCommerce Thank You Page

The following code lets you add tracking code to the WooCommerce Thank You page after a purchase. The $order variable contains all the relevant information for that order so you can send the details to the tracking service you use.

Pay attention to the comments in the code to understand where to add the tracking code and how to use this variable:

/**
 * Add custom tracking code to the thank-you page
 */

function my_custom_tracking( $order_id ) {

	// Lets grab the order
	$order = wc_get_order( $order_id );

	/**
	 * Put your tracking code here
	 * You can get the order total etc e.g. $order->get_total();
	 */
	 
	// This is the order total
	$order->get_total();
 
	// This is how to grab line items from the order 
	$line_items = $order->get_items();

	// This loops over line items
	foreach ( $line_items as $item ) {
  		// This will be a product
  		$product = $order->get_product_from_item( $item );
 
  		// This is the products SKU
		$sku = $product->get_sku();
		
		// This is the qty purchased
		$qty = $item['qty'];
		
		// Line item total cost including taxes and rounded
		$total = $order->get_line_total( $item, true, true );
		
		// Line item subtotal (before discounts)
		$subtotal = $order->get_line_subtotal( $item, true, true );
	}
}
