how to Identify/detect Object Name from ID on visualforce page via Apex code?

please suggest how can we Identify/detect Object Name from ID on visualforce page via Apex code?

 

i am trying to dynamically pick the name of standard/custom object from salesforce object id on a visualforce page.

 

please suggest if you have any ideas on that.

Thanks.

Here's some sample code you can adapt:

 

http://www.salesforcefast.com/2012/02/get-object-name-from-record-id.html

 

The output is the label of the Sobject, but you can pretty easily change that to return the API name, and from that you can instantiate a new Sobject as needed.

 

Good luck!

Here's another approach wherein you use a static class that can be shared by many controllers/triggers:

 

public class MySingleton {
public  static Map<String, Schema.SObjectType> 		sobjToSobjDescribeMap			= null;

public static Boolean idIsOfSObj(String SObjName, ID theId) {
		if (sobjToSobjDescribeMap == null) 
			sobjToSobjDescribeMap= Schema.getGlobalDescribe();
			
		String idKeyPrefix = theId != null ? ((String) theId).substring(0,3) : null;
		if (sobjToSobjDescribeMap.get(SObjName).getDescribe().getKeyPrefix() == idKeyPrefix) return true;
		return false;	
	}
}

// invoke this from anywhere by using if (MySingleton.idIsOfSObj(someIdVbl,'Opportunity')) { /* true logic }

 This way you avoid the Governor limit on Describe calls
