How to set up a filter by date in Bitrix?

Question

PHP

I tried different options, it does not help - it displays the wrong range and that's it.

$arFilter = Array("IBLOCK_ID"=>array(2, 3), "<ACTIVE_FROM"=> "15.08.2015");
  $res = CIBlockElement::GetList(Array("PROPERTY_START_DATE" => "DESC"), $arFilter, false, false, $arSelect);

Answer 1

I don’t know how for standard date fields, but for date / time properties - this format works

trim(CDatabase::CharToDateFunction(ConvertTimeStamp(strtotime("30.08.2015"),'FULL')),"\'"))

Answer 2

The date must be in the same format as the database.
