How to send attribute values in invoice mail in magento-1.9.1.1

Question

I have developed one website on magento-1.9.1.1. I need to add the weight attribute values along with order information in invoice email.

Answer 1

you can simply add information here.

app/design/frontend/[package name]/[your theme]/template/email/order/items/invoice/default.phtml

You can get the product item weight like this:

<?php echo $_item->getOrderItem()->getWeight(); ?>

Answer 2

Magento,does not save weight of item at Sales invoice model.You did not find any field at sales_flat_invoice_item table.

Magento save an order item weight at sales items table, so you need to call Mage_Sales_Order_Item Object of that sales invoice ite,

$orderItem = $_item->getOrderItem();
$orderItem->getWeight(); // get weight
