Field IDs and Server Instance Split

A Salesforce Organization that I'm involved in is going to be part of a server split.  Somewhere in this I have a controller that uses a hard coded field ID in order to prepopulate fields when visiting a link.  Am I correct in thinking this will be affected in the server split?

Is there a way to dynamically get the ID of the field so I don't have to hard code this in?

Yes this will most likely impact your org. The SFDC Best Practice is not to hard code the ID's a field in your Apex / VF / Javascript code.

Here are two common options to solve your problem.

1. Move this from a hard coded ID to a Custom Setting. If you move this to a Custom Setting, when you move your Org you can easily change the ID of the field without doing a code deploy.

2. Instead of using Hard Field ID's look at using FieldSets to accomplish your goals. This is why Field Sets where built in the first place. http://www.salesforce.com/us/developer/docs/pages/Content/pages_dynamic_vf_field_sets.htm

Hey Cory,

Thanks for the reply.  I am using the field ID to prepopulate a form thorugh URL using the CF0+ID format.  I think what you mean by field sets is to create a custom VF edit page in which case I can just pass the parameters in the URL?  Currently I am linking to the standard edit page so I would have to create another VF page for this.  Not sure of what I'll do at the moment. 

Thanks again for the answer.
