How to modify the Summary of your order in the invoice emails

Hello,

I would like to add the product category into the email notifications, how do I go about adding this information?

I know the following views exist in the back-end:

Order creation notification - email used when an order is created. Send to the user itself.
Order status notification - email used when an order is modified (could be confirmed, cancelled, shipped...). Send to the user itself.
Order administrator notification - email used when an order is created. Send to the administrator.

I know where the views are located system --> emails

However, I don't know what to insert into the views. I know it's somewhere in the table code below, but where and what do I insert exactly?

<!--{START:PRODUCT_LINE}-->
<tr>
<td style="border-bottom:1px solid #ddd;padding-bottom:3px;">
{LINEVAR:PRODUCT_IMG}
{LINEVAR:PRODUCT_NAME}<!--{IF:ORDER_PRODUCT_CODE}--> {LINEVAR:PRODUCT_CODE}<!--{ENDIF:ORDER_PRODUCT_CODE}-->
{LINEVAR:PRODUCT_DOWNLOAD}
{LINEVAR:PRODUCT_DETAILS}
</td>
{LINEVAR:CUSTOMFIELD_VALUE}
<td style="border-bottom:1px solid #ddd;padding-bottom:3px;text-align:right">{LINEVAR:PRODUCT_PRICE}</td>
<td style="border-bottom:1px solid #ddd;padding-bottom:3px;text-align:right">{LINEVAR:PRODUCT_QUANTITY}</td>
<td style="border-bottom:1px solid #ddd;padding-bottom:3px;text-align:right">{LINEVAR:PRODUCT_TOTAL}</td>
</tr>

Thank you!

Thanks, Jerome.

What do you recommend as an alternative or a workaround then? I have different products in 2 different categories with the same name, picture and price. How can I differentiate what the product is exactly from the email invoices?

The back-end orders section provides the product name and product code, is this something that can be easily entered into the emails?

Jerome, Nicolas,

Unfortunately displaying the product code isn't enough for what I need, I really need to display the category of the product in the checkout page. How can I accomplish this?

Regards.

Nicolas, understood, thanks.

On a related note, I turned on "Display product code" under Configuration --> Display.

As you can see in the image below, in the cart view, there is not much space between the product name and product code. How/where can I adjust the spacing between the product name and code?

Thank you Jerome.
