Disabling adding new product

[veijari]

Hi, our customer uses another software where they import all the products in PS, they also want to use the same ID(force ID enabled) as in the other software, therefore we want to disable manual adding of a product in admin. This way we won't get duplicates.

I've found a way to do this in /src/PrestaShopBundle/Controller/Admin/ProductController.php at line 353: 

 $toolbarButtons['add'] = array(
            'href' => $this->generateUrl('admin_product_new'),
            'desc' => $this->trans('New product', 'Admin.Actions'),
            'icon' => 'add_circle_outline',
            'help' => $this->trans('Create a new product: CTRL+P', 'Admin.Catalog.Help'),
        );

So if I comment this out it works, but then when we update the PS this change will be gone. Is there a way to override this somehow, or manually hide it via css, or maybe with a hook?

Any help would be appreciated.

Why not remove the user rights to add new products?

@JBW That is a really good question! I have no idea why I did not come up with that easy solution..

Thank you for saving my time!
