OnBeforeIBlockElementAdd

bool
event_handler(
   array &arParams 
);

Parameters

ParameterDescription
arParams An array of the new information block element fields.

Note
The parameter(s) of this handler are references to the original variables. Hence, altering their values from within the handler causes changing values of the source variables passed to the handler.
