How to hide categories with no products?

[Former Member]

We are not using WCMS in our website. We get the top navigation menu from a custom category heirarchy which we have made. So in a case, where a category has no products tagged to it, we shouldn't display it.

I guess we could check if the category has products getProducts() and then if its subcategories have products. but is there a better way to do this?. Is there any existing service to get all products associated to a category?

The service you want is ProductService. There are methods for checking if a category has products as well as returning all products for a given category. Based on your example I think productService.containsProductsForCategory(aCategoryModel) should do the trick.
