Hi,

Following is my code for sening email from a button on a custom object Safari__c. 

Safari__c is defined as the standard controller for the page. At the end of the code, if the mail sent is successful, I want to be able to update certain fields (Email_Flag__c and Email_Date__c) on the Safari__c object. I am defining a new Safari__c in the constructor, but I am not able to access these fields. 

How can this be done?? 

Any kind of help is greatly appreciated.

Thanks in advance.

public with sharing class SendEmailPage {

public String contactEmail1 {get; set;}
public String contactEmail2 {get; set;}
public String contactEmail3 {get; set;}
public Id AccId {get; set;}

public SendEmailPage(ApexPages.StandardController controller) {
try{

Safari__c test=new Safari__c();
test=[Select Account__c,Email_Flag__c,Email_Date__c From Safari__c Where id=:ApexPages.currentPage().getParameters().get('id')];
AccId=test.Account__c;}

catch(Exception e){
