Insert 18 Digit Contact ID into Contact

This is pretty simple although I am a complete newb to triggers and Apex code. I have a field "Contact18Dig" on the Contact object that I am trying to populate the 18 digit contact id to. Any time a new contact is created or the "Contact18Dig" field is modified, I want the "Contact18Dig" field to populate with the full contact ID. If I create a contact and then edit the record, this code works fine. But, it is not inserting the 18 digit contact upon creating a new contact.

 

Any assitance, guidance, or corrected code examples are much appreciated.

 

trigger ContactID18Digit on Contact (before insert, before update)    
{
  for(Contact c : Trigger.new) 
  {
    if(c.Contact18Dig__c != c.id) 
    {
        c.Contact18Dig__c = c.id;
    }
  }
}

In a before insert trigger there is no id, so for the insert case, you'll need an after insert trigger instead.

if the trigger is before insert, the ID is not generated yet..

Thank you SimonF and S_Lie for your response. I have changed the code to after insert although I am now receiving an error when creating a new contact. If I edit a field on an existing record, no error is received. The "Contact18Dig" field is editable at the field level as well as the page layout. Is this a record locking issue? Should I be breaking this out into a class and "hooking"? Should I be using "Trigger.old"? Again, I am a complete newb so any help or code assistance is appreciated.

  }
}
