Product code in PDF invoice

Hi,

The product code will actually display automatically on the invoice if you have the "show product code" setting activated in the HikaShop configuration. Note that this setting will also activate the display of the product code on the product details page, and other places.
If you only want it in the PDF invoice, you can edit the file plugins/hikashop/attachinvoice/attachinvoice/invoice.php and change the line:
if ($config->get('show_code')) {
to:
if(true) {

Hi,

Well, in that case, you probably have an old version of the plugin yes.
In that file, you can add that line of code to display the product code:
echo '<br/>'.$product->order_product_code;
That's the line already there by default.
Now I'm not sure what's the status of the code in your version of the plugin, so I can't say where to add it exactly.
Search for order_product_name and add that code after the line with order_product_name in it.
