Trigger Help on Campaign Primary source update?

Hi Everyone,
Basically what I need is to override the default behavior of SFDC with regards to setting the Primary Campaign Source in Opportunities. The default behavior is it takes the last campaign associated with a contact and make it the Primary Campaign Source in the Opportunity. WE DO NOT WANT THAT. What we want is the FIRST RESPONDED Campaign of the contact to be the Primary Campaign Source.
I written code above only takes the first associated campaign, we need to updated with first responded campaign.

Here is my code:

trigger SetPrimaryCampaignSource on Opportunity (before insert) {
    Set<Id> contIds = new Set<Id>();
   for (Opportunity opp : Trigger.new) {
        contIds.add(opp.Sourced_by__c);
    }
 
    contIds.remove(null);
 
    if (!contIds.isEmpty()) {
        Map<Id, CampaignMember> campaignMap = new Map<Id, CampaignMember>();
 
        for (CampaignMember cm : [
            select ContactId,
                CampaignId,
                Status
            from CampaignMember
            where ContactId in :contIds
            order by CreatedDate asc
            nulls last
        ]) {
            campaignMap.put(cm.ContactId, cm);
        }
 
        for (Opportunity opp : Trigger.new) {
            if (campaignMap.containsKey(opp.Sourced_by__c)) {
                opp.CampaignId = campaignMap.get(opp.Sourced_by__c).CampaignId;
            }
        }
    }
}


Thanks

Hi Guru,

Try This : 

  
trigger SetPrimaryCampaignSource on Opportunity (before insert) {
    Set<Id> contIds = new Set<Id>();
   for (Opportunity opp : Trigger.new) {
        contIds.add(opp.Sourced_by__c);
    }
 
    contIds.remove(null);
 
    if (!contIds.isEmpty()) {
        Map<Id, id> campaignMap = new Map<Id, id>();
 
        for (CampaignMember cm : [
            select ContactId,
                CampaignId,
                Status
            from CampaignMember
            where ContactId in :contIds
            order by CreatedDate asc
            nulls last
        ]) {
            campaignMap.put(cm.ContactId, cm.CampaignId);
        }
 
        for (Opportunity opp : Trigger.new) {
            if (campaignMap.containsKey(opp.Sourced_by__c)) {
                opp.CampaignId = campaignMap.get(opp.Sourced_by__c);
            }
        }
    }
}
