Hi,
Go in the menu Display>Views and search for the pdf_layout view.
You'll find the 4 different layout files corresponding to the "layout" setting in the PDF invoice plugin.
So edit the one corresponding to the layout you're using.
There, the product name is displayed with the code:
Code:
echo implode('<br/>',$this->str_split_unicode(strip_tags($product->order_product_name),50));
In $product , you don't directly have the custom product fields data, however you have the product_id.
So, you can use such code, below the product name display code:
Code:
$productClass = hikashop_get('class.product');
$productData = $productClass->get($product->product_id);
echo '<br/>'. $productData->xxx;
where xxx is the column name of your custom product field.
