What event to use when quickly editing an element?

Question

1C-Bitrix

Hi all!
I'm trying to batch update the "SORT" field. At the moment I'm using the OnAfterIBlockElementUpdate event , everything works, but it's not convenient that you need to go into each element. How to correctly implement a batch change of the "SORT" field?
Select 10 elements, click "Edit" and just save. How to be? Where to dig?

Answer 1

Do you need to bulk update the fields of the elements?
It is not clear why to use (and how they managed) the OnAfterIBlockElementUpdate event
-- Here is an example of how to massively
update only one property, without overwriting others, with one request (code execution, i.e. one page update)

<? 
 $ELEMENT_ID = array( 2, 3, 600, 543, 343, 34, 666, 23);
 $PROPERTY_CODE  =  "PROP1" ;   // код свойства 
 $PROPERTY_VALUE  =  "Синий" ;   // значение свойства 
foreach($ELEMENT_ID  as $kel):
 // Установим новое значение для данного свойства данного элемента 
CIBlockElement::SetPropertyValuesEx( $kel ,  false ,  array ( $PROPERTY_CODE  =>  $PROPERTY_VALUE ));
endforeach;
 ?>

In your case, you need to update not the Property property, but the "SORT" => "ASC" field,
you can get the id list for the array via getlist
In general, there was a module on the market that was paid with a test period of 7 days. This is enough to complete your task.
