How to display property values ​​of linked elements in Bitrix?

Question

PHP

Hello!
There is infoblock-1, which includes binding to the elements of infoblock-2. The task in the news.detail template of infoblock-1 is to display the values ​​of the properties of the linked elements. It is necessary to display 3 properties from infoblock-2: ADDRESS (string), PHONE (string) and LOGO (file).
So far, it was possible to display anything (property name, ID, etc.), but not their values. Can you please tell me if this is possible at all? If possible, show on some simple example (preferably with a file).
Thanks

Answer 1

as a rule, it is done like this:
in the result_modifier of the news.detail template, you need to call getlist , in which we will get the necessary fields of related elements.
Example:

$arSelect = Array("ID", "ACTIVE_TO"); //здесь перечисляем нужные поля из связанных элементов
$arFilter = Array("IBLOCK_ID"=>6, "ACTIVE"=>"Y","ID"=>$_GET["time_id"]); //$_GET["time_id"] - заменить на массив с твоими id связанных записей

$res = CIBlockElement::GetList(array("SORT" => "ASC"), $arFilter, false, Array("nPageSize"=>PHP_INT_MAX), $arSelect);

$time_items = array();
while($ob = $res->GetNextElement())
{
  $arFields = $ob->GetFields();
  $time_items[] = $arFields;
}

$arResult["TIME_ITEM"] = $time_items;

Well, in template.php then you use $arResult["TIME_ITEM"]
And carefully read the section "arSelectFields" in the documentation - there you need to observe the correct format when receiving parameters of related elements

Answer 2

Your way only shows the value id, then you need to use GetByID
$res = CIBlockElement::GetByID($arResult["TIME_ITEM"]['0']['PROPERTY_USLUGI_ELEMENT_VALUE']);
if($ar_res = $res->GetNext())
echo $ar_res['NAME'];
