How to display data in the admin panel?

Question

1C-Bitrix

There is a site on Bitrix, in which the user receives points for some specific actions - for example, for registration. Points are shown in the user's personal account using

$bonus = 0;
$arSelect = Array("ID", "PROPERTY_BAL");				 
$arFilter = Array("IBLOCK_ID"=>9, "ACTIVE_DATE"=>"Y", "ACTIVE"=>"Y","PROPERTY_USER"=>$USER->GetID());
$res = CIBlockElement::GetList(Array(), $arFilter, false, Array("nPageSize"=>50), $arSelect);
while($ob = $res->GetNextElement())
{
 $arFields = $ob->GetFields();
  $bonus += $arFields["PROPERTY_BAL_VALUE"];
}
$rsUser = CUser::GetByID($USER->GetID());
$arUser = $rsUser->Fetch();

I would like the user's points to be shown in the admin panel in the "list of users". Where should I add the above code so that it is reflected in the list of users? How in general should such things be solved in Bitrix? What class should be extended?

Answer 1

Well, there is one option:
- Create a custom field of type "number" without user editing rights
- Write code that, when adding / deleting / updating an element, sets the value of the field to the corresponding value if the points date has not expired
- Write an agent that receives elements every day information block of points that expired yesterday and updates the user data for the current date
