Order Information in Admin

[jmbdev]

Hello,

I want to display additional information on the order details page in the Administrator section.

Specifically, I want to display the prices excluding tax for each product line as well as for the total order, and the percentage discount applied to each product.

I have already added the excluding tax price information for each product line by creating a module that modifies the file PrestaShop/Admin/Sell/Order/Order/view.html.twig.

This was possible because the file src\PrestaShopBundle\Controller\Admin\Sell\Order\OrderController.php, which manages this, injects the variable $orderForViewing in which this information is already present.

So, I would like to access other information and make it available to the view PrestaShop/Admin/Sell/Order/Order/view.html.twig.

However, OrderController is located in the /src folder of the project. It seems that we cannot override classes located in this folder.

How can I proceed differently?

Prestashop version 1.7.8.5

You can decorade a controller or (easier) insert your custom hook in the twig file and call it in your module.
