Hide Item Number from Paypal Checkout

After someone orders something from the shop and gets directed to paypal, I would like the Item Number hidden from the order summary on the paypal screen. How do I do this?

You can try to remove the line:
$vars["item_number_".$i]=$product->order_product_code;
from the file plugins/hikashoppayment/paypal.php but it might not work because paypal might require that parameter.

If that doesn't work, then there is no solution for that.

Is there a way to modify value that goes to paypal for Item Number?
For my store I am using Characteristics, so a single product can have three characteristic with different prices. When I select one, then check out, the item number thats given is product name and the ID of the characteristic selected (i.e. CoolBlueCar_3).

Instead of the ID, can I use the name of the characteristic, I need this so that on Paypal the person shipping can identify exactly which product it is they need to send, the characteristic id will not mean anything to them.

maybe using: $vars["item_number_".$i]=$product->order_product_name; instead of product_code?

UPDATE:
I just tested by putting order_product_name like above, but did not work. It showed the product name and added <span class="hikashop_product_variant_subname"></span> after it. Any other ideas?

like that:
$vars["item_number_".$i]=strip_tags($product->order_product_name);

Thank you, I tried that but it only gives me the name of the product. It does not give the name of the Characteristic.

That should be the case with the option "Append characteristic value to product name" in the Display tab of the configuration.

Mine is selected "yes", but the problem is that it appends the ID (1, 2, 3), not the name of the characteristic. And the id's are not editable.

Can you do a screenshot of the values of your characteristic ?

I've never seen ids of characteristic values added to the name of the products.

I think I figured it out. There are two areas where you set values for characteristics, in the actual characteristic settings, and then in the individual product Variant settings. I thought the value shown in the paypal check out was the one in the Characteristic ID. I just went to an individual product, clicked on Varient and notice there is the "Code" field that can be edited, I assume THAT is the one that shows in paypal check out. I will edit one then do a check out to see if the new value will show.
