How to display the article in the list of goods in Bitrix?

Question

1C-Bitrix

CCatalogProduct::GetList does not display the article in the product list.
I have to use GetByIDEx($p["ID"])['PROPERTIES']['ARTNUMBER']['VALUE'] for each id I get,
but this is very slow
. Is there an alternative?

Answer 1

You collect an array of product IDs, pass it to the CIblockElement::GetList() filter, grab the articles with one request, then stuff them into the necessary elements.
