I am assuming that [pumpID] is for MySQL ID of pump in table so
Have you done like this? :

PHP код:

forward onCreatePump(localPumpID);
public onCreatePump(localPumpID)
{
     pumpData[localPumpID][pumpID] = cache_insert_id();
     return 1;
} 


Make sure that id is the PRIMARY_KEY in mysql db.
and why aren't you inserting the coords of pump?
