Transfer product category to order items

For my client it is important to show the category from which the items were ordered (during the making of the wishlist or shopping cart). My client wants to retrace the path of the ordering process. That's why I want to add a field for every order item in which that category is listed.

Therefore I thought to add a custom field 'item' via your custom fields menu, or add a table column myself in table 'order_product' or 'cart_product. I think ordering in this case only may be possible from the category list (not from product details, because the category is lost over there) called from the menu list / div.
Maybe I should make an override for <listing_div.php>, but at least for <add_to_cart_listing.php>, I think.

But how to do this? How to transfer the (sub)category which is shown, to the new database field, at the moment of ordering. And what is the best information to transfer? Perhaps the title (page title) and may be the url, but otherwise the category ID (but than i hav to translate this later on to a category name in the order).

For the URL I need in <add_to_cart_listing.php> something like:

<?php echo hikashop_currentURL(); ?>

Thank you, Nicolas. But most of the products are in multiple categories (sometimes over 20). And we just want to show the category from which the items were ordered (during the making of the wishlist or shopping cart).

So someone orders a component (product) for a Mercedes Vito (one of the categories). You can buy this component for many other cars (other categories, but not all). But in the order/wishlist I want to see that the client selected the (category) Mercedes Vito (or other car) before clicking the Add to cart button. So I want to know his order path. In that way, we can assure the client buys only correct products, without mistakes.

I hope you can help me to solve this problem.

Kind regards,
merry christmas,

Hi Nicolas,

That sounds hopefull. But after following your instructions, there is no catgerory id in the tables added.

Simplified breadcrumb is turned off now.
I created a custom field as you said. The config is presented in the first screenshot. Of course I have tried some other settings too.
For testing purpose I do not hide anything at this moment.
In the database I can see the new table column "category_pathway" in both tables.
But in the List-Div view (shown in the second screenshot), you see the value of this new custom field is nothing more than "category_pathway".
After adding to cart, the table fields "category_pathway" stay NULL.

In the view files (list and add) I do not see any declaration of the category pathway, so I do not understand where to look for better results. Any idea what I am missing or doing wrong?

Thanks again.

Strange, but this transfers the product id... (not category id).
And I need to make use of the product detail page first.

Is there any other parameter I can use to transfer the category id when submitting the order button in the list/div view (products in category)?
Or otherwise the page url and page title, at the moment of ordering (from the product in categerory view)?
