Why is DISPLAY_PROPERTIES empty in trade offers?

Question

1C-Bitrix

Everything is fine in PROPERTIES, but DISPLAY_PROPERTIES is empty for each trade offer in the product card. In the settings of the component dripped everywhere included this only property. Can't beat him anyway. What is the jamb?

      empty

Answer 1

dude, this is a Bitrix bug. look here, in result_modifier.php add this code

$arResult["DISPLAY_PROPERTIES"] = array();
foreach ($arResult["PROPERTIES"] as $pid => &$arProp)
{
   if((is_array($arProp["VALUE"]) && count($arProp["VALUE"])>0) ||
   (!is_array($arProp["VALUE"]) && strlen($arProp["VALUE"])>0))
   {
        $arResult["DISPLAY_PROPERTIES"][$pid] = CIBlockFormatProperties::GetDisplayValue($arResult['ITEMS'], $arProp, '');
   }
}

$arResult['SHOW_OFFERS_PROPS'] = true;

Answer 2

Bitrix version 19.0 had a similar problem, it was solved by adding checkboxes in the property settings and when calling the DETAIL_OFFERS_PROPERTY_CODE parameter
