Question

1C-Bitrix

foreach($ID2 as $_id2) {

                            $rs = CIBlockSection::GetList(Array("SORT"=>"ASC", "NAME"=>"ASC"), Array("IBLOCK_ID"=>17, "ACTIVE"=>"Y", "SECTION_ID"=>$_id2));
                            echo '<select class="cartridge-name1"  id="prodid'.$_id2.'" style="border: #d2d2d2 2px solid; margin: 0px 0px 10px; padding: 5px; width: 150px;display:none"><option value="">Картридж</option>';
                            while($ar = $rs->GetNext())  echo '<option value="'.$ar["ID"].'">'.$ar["NAME"].'</option>';
                            echo '</select><input type="number" class="prodid2'.$_id2.'" style="width: 35px;display: none;">';
                        }?>

There is a code that displays the name of the product and, in theory, should display the ID, the point is, there is a button that adds the product to the cart with ajax, but the ID is not correct, i.e. does not match the product

Answer 1

Can't you see yourself? CIBlockSection::GetList - selects sections of the same, not elements.
Use CIBlockElement::GetList
