Multiple binding to elements and filtering via GetList

Question

PHP

There is a property which is a binding to elements. (eg PROPERTY_GOAL). It is necessary to display all elements in the properties of which there is a binding to a certain element, but there is no binding to another element, using CIBlockElement::GetList. The ID of the tethered blocks by which to filter is known.
How to correctly set $arFilter? So far, the maximum has reached:

$arFilter = array(
"IBLOCK_ID"=>$blocks, 
"IBLOCK_SECTION_ID"=>$sectionIDS, 
"PROPERTY_GOAL.ID"=>466,  //если в свойстве GOAL  указана привязка к элементу с ID 466
"!PROPERTY_GOAL.ID"=>462, // и нет привязка к элементу с ID 462, то данный элемент подходит и попадает в $arResult 
"PROPERTY_RECOMEND_VALUE"=>"да",
"ACTIVE_DATE"=>"Y", 
"ACTIVE"=>"Y");

Such filtering works, but I would like to be sure that it works 100% correctly. I would be glad for any help / hints, etc.

Answer 1

I would like you to tell me exactly where you are not sure, because the code is correct and, as you say, it works.
On the other hand, if I understand correctly, you can simply use the "PROPERTY_GOAL_VALUE" and "!PROPERTY_GOAL_VALUE" constructs (if they work correctly with a multiple parameter value). It seems to me that since the binding goes anyway by ID (PROPERTY_GOAL_VALUE will contain exactly the IDs of the elements to which it is attached), then it makes no sense to pull out the ID from the bound element.

Filter with complex logic
Under the call parameters in the documentation.
More or less like this.
$arFilter = array(
"IBLOCK_ID"=>$blocks,
"IBLOCK_SECTION_ID"=>$sectionIDS,
array(
"LOGIC" => "AND",
array("PROPERTY_GOAL.ID" => 466),
array("!PROPERTY_GOAL. ID" => 462),
),
"PROPERTY_RECOMEND_VALUE"=>"yes",
"ACTIVE_DATE"=>"Y",
"ACTIVE"=>"Y");
