Hello,

 

tl;dr. I need to order my product list (in the catalog pages) by ps_product_shop.unity.

 

In prestashop 1.7.5 you have this field in product/price/ screen

The field on the right (the one with '2' inside) is refered in the table 'ps_product_shop->`unity`

I want to sort my product list using this field

 

I have tried to change the `getProductSearchQuery()` method in "CategoryController.php" like so


            ->setSortOrder(new SortOrder('product', Tools::getProductsOrder('by','unity'), Tools::getProductsOrder('way')))

It doesn't work (but if I put for exemple 'date_upd' instead, it does sort by date update)

 

I also tried to change the Product.php class

`getProducts()` method. But no matter what I do in that class, nothing change. Even if I remove the code inside that method, the catalog keep showing up and no error.
