How Do I Access Order Item Data in WooCommerce 3 Using WC_Order_Item_Product?

Accessing Order Items and WC_Order_Item_Product in WooCommerce 3

In WooCommerce version 3.0, retrieving properties directly from order items is no longer feasible. To retrieve information about a specific order item, you need to use the appropriate getter methods provided by the WC_Order_Item_Product class.

Accessing Order Item Data:

• Product ID: $order_item->get_product_id()
• Variation ID: $order_item->get_variation_id()
• Quantity: $order_item->get_quantity()
• Order ID: $order_item->get_order_id()
• Product Name: $order_item->get_name()
• WC_Product Object: $order_item->get_product()
• WC_Order Object: $order_item->get_order()
• Item Subtotal (non-discounted): $order_item->get_subtotal()
• Item Subtotal Tax (non-discounted): $order_item->get_subtotal_tax()
• Item Total (discounted): $order_item->get_total()
• Item Total Tax (discounted): $order_item->get_total_tax()

Accessing Data and Metadata:

• Data Array: $order_item->get_data()
• Metadata Array: $order_item->get_meta_data()
• Specific Metadata (by Meta Key): $order_item->get_meta('meta_key')
• Formatted Metadata: $order_item->get_formatted_meta_data(...)

Array Access:

While the array access method is deprecated, you can still use it for accessing common data:

• Product ID: $order_item['product_id']
• Variation ID: $order_item['variation_id']
• Product Name: $order_item['name']
• Quantity: $order_item['quantity']
• Non-Discounted Subtotal: $order_item['subtotal']
• Non-Discounted Subtotal Tax: $order_item['subtotal_tax']
• Discounted Total: $order_item['total']
• Discounted Total Tax: $order_item['total_tax']

Additional Notes:

• To get the WC_Order_Item_Product object from an order item ID, use: $item = new WC_Order_Item_Product($order_item_id);
• To get a list of order items from an order ID, use: $items = $order->get_items();
