How to get an array of id elements from FILTER_NAME Bitrix?

Question

1C-Bitrix

Good afternoon!
The smart filter component has the FILTER_NAME parameter, and the arrFilter variable in which the filter will store the generated filter array. Only the filtered array of element IDs is needed. Is it possible to pull this from a variable?

Answer 1

No, you can't, because arrFilter will contain exactly the filter, not the element IDs. But you can use this filter in CIBlockElement::GetList to get the ID of all elements matching this filter
