Why can't AddEventHandler work in bitrix?

Question

PHP

Code in init.php

AddEventHandler("catalog", "OnDiscountAdd", Array("MyClass", "OnDiscountAddTest"));

class MyClass
{
  function OnDiscountAddTest($arFields)
  {
    var_dump($arFields);
    echo("test");
    exit();
  }
}

Actually, when adding a discount, nothing happens. Where is the mistake. Tried both OnDiscountAdd and OnBeforeDiscountAdd.

Answer 1

Try calling the CCatalogDiscount::Add method and see if your handler works.
