or maybe all products onone page for me it will be ok //I found a solution how to display all the products on one page In AllProcuctsController.php in line
'products' => Product::getAllProducts($this->context->language->id, (int)($this->p) - 1, (int)($this->n), false, $this->orderBy, $this->orderWay),
I changed $this->n to $nbProducts
'products' => Product::getAllProducts($this->context->language->id, (int)($this->p) - 1, (int)($nbProducts), false, $this->orderBy, $this->orderWay),
Anyone know how to display "quantityDiscount" from the product page for the list of products
