Scenario 
I want to create contact lookup(Notification_Receipient_Email_c) on opportunity object from email field(Notification_Receipient_Contact_Emailc) and if email doesnt exist then first create contact and assign it email and then create// its lookup.And created contact name should be displayed in Notification_Receipient_Name_c field.

My trigger is creating lookup and if email exist or doesnt exist ,it is creating a contact and then creating its lookup except that it is not displaying the contact name in my  Notification_Receipient_Name__c

Example for when contact exist:-

Notification_Receipient_Contact_Email__c
- shivi1@sf.com //this email exist

Notification_Receipient_Email__c-shivani//lookup created with the contact name where email exist

Notification_Receipient_Name__c
         //novalue (expected value-shivi)

Exame for when contact not exist:-

Notification_Receipient_Contact_Email__c- test@chk.com //this email not exist

Notification_Receipient_Email-test//lookup created by creating its contact

Notification_Receipient_Name
         //novalue (expected value-test
Plz help me out how to display name in above field as well...how to incorporate that logic

I have created a trigger that will autopopulate Lookup field(Account Name,npsp__Notification_Recipient_Contact__c) by mapping custom fields (My_Account_Name__c,npe01__HomeEmail__c) respectively on opportunity object.
My Account Name(My_Account_Name__c) ---> Account Name(Account Lookup ) Myemail(npe01__HomeEmail__c) ---> npsp__Notification_Recipient_Contact__c(Contact Lookup)
i WANT TRIGGER SHOULD ONLY WORKS ON WHILE INSERTING RECORD.hENCE i USED BEFORE INSERT.But, trigger only creating a lookup to email field not for account field .I want tit shold create lookup to both fields i.e account as weell as contact field.

here is my code

trigger opportunityTrigger on Opportunity (after insert,before insert) {

If (trigger.isBefore && trigger.isInsert) {
      OpportunityTriggerHandler.InsertContactEmail(Trigger.New); }
/* else { OpportunityTriggerHandler.afterInsertOpportunity(Trigger.new); } */
}

trigger handler class
public with sharing class OpportunityTriggerHandler {
   public static void afterInsertOpportunity(List<Opportunity> opplst) {
        set<Id> setOfOppIds = new set<Id>();

            setOfOppIds.add(objopp.Id);
        }
       if(setOfOppIds != null && setOfOppIds.size() >0){

                                in:MapContactName.keySet()];
        for(Contact con : conList){

Hello,

I have a basic trigger that needs to update a lookup field (Discount_code_LU__c). I'm just trying to map the lookup field with the text field (Discount_code__c). The lookup field (Discount_code_LU__c) is related to the Product object. Any assistance will be greatly appreciated!

Thank you!!

trigger UpdateOpportunityProduct on Opportunity (before insert){
    
 for(Opportunity opp:Trigger.new)
 {
     opp.Discount_code_LU__c =  opp.Discount_code__c ;
          
}
}
