using extends \CCatalogCondCtrlComplex inheritance and passing it
in the Generate method

"checkField('".$arControl['FIELD']."', '".$arOneCondition["value"]."', '".$arParams['FIELD']."')===".$logic;

but $arParams['FIELD'] stores the string = $arProduct

how do I get the values ​​of the $arProduct array and not the string

Answer 1
