Hi,

I have to add the contacts to campaign members..

Here is my code.

public PageReference camprollup(){

       list<CnP_Transaction__c> listtransactions = [selectName,Contact__c,sf_Campaign__c,Email__c,Donation_Name__c,Campaign__c  fromCnP_Transaction__c where sf_Campaign__c!=null OR Campaign__c!=null];

    for(CnP_Transaction__c lst : listtransactions){ 

      Map_Camp_To_Contact_Id.put(lst.Id, lst.sf_Campaign__c);   

    CampaignList.add(lst.sf_Campaign__c);

        EmailSet1.add(lst.Email__c);   

        OrdnumSet.add(lst.Id);   

       }   

try{ 

  if(!listtransactions.isEmpty()){ 

       list<Campaign> listcampaign     = [SELECT Id, Name FROM Campaign WHERE Id IN :CampaignList];           for(Campaign cn :listcampaign){   

         Map_Camp_Id.put(cn.Id, cn.Id);   

       }

         List<CampaignMember> campmem = [select contact.Email,Campaignid,Contactid from CampaignMember where CampaignId!=null and CampaignId = :CampaignList]; 

       for(CampaignMember cm :campmem){ 

          Map_CamId_ConId.put(cm.CampaignId,cm.ContactId); 

       }
       list<Contact> ContactMap1=[Select Id,Email,npo02__Household__c from Contact where Email IN :EmailSet1];       for(Contact k:ContactMap1){ 

        Map_Contact_To_Id.put(k.Email,k.Id);   

    }   

 CampaignMember CreateMem=new CampaignMember();  

   for(Integer i = 0;i<listtransactions.size();i++){ 

if(listtransactions[i].sf_Campaign__c!=null && Map_Contact_To_Id.get(listtransactions[i].Email__c)!=null && Map_CamId_ConId.get(Map_Camp_Id.get(listtransactions[i].sf_Campaign__c))!=Map_Contact_To_Id.get(listtransactions[i].Email__c)  ){

        CreateMem = new CampaignMember(Campaignid=Map_Camp_Id.get(listtransactions[i].sf_Campaign__c), Contactid=Map_Contact_To_Id.get(listtransactions[i].Email__c), Status='Received');         Map_CamId_ConId.put(Map_Camp_Id.get(listtransactions[i].sf_Campaign__c), Map_Contact_To_Id.get(listtransactions[i].Email__c));//listtransactions[i].Contact__c);             campmember.add(CreateMem); 
     } 
      }
