Trigga What?

A simple non-profit Salesforce Trigger example

Trigger

[java]

trigger NewDonationAfterPayment on pymt__PaymentX__c (after insert) {
PaymentManager.handleNewPayment(Trigger.New);
}

[/java]

Apex Class

[java]
public with sharing class PaymentManager {

public Class PaymentManagerException extends Exception {}

public static void handleNewPayment(List <pymt__PaymentX__c> newPayments) {
List <pymt__PaymentX__c> completedPayments = new List <pymt__PaymentX__c>();
List <Opportunity> donationList = new List <Opportunity>();
List <OpportunityContactRole> ocrList = new List <OpportunityContactRole>();

// Loop through all new Payment objects in the trigger and add the ones with a 'Completed' status and Type of 'Payment'.
for (pymt__PaymentX__c payment : newPayments) {
if (payment.pymt__Status__c == 'Completed' && payment.pymt__Transaction_Type__c =='Payment') {
completedPayments.add(payment);
}
} //close for-loop

// If there are new Payments that fit our criteria above then move forward.
if (completedPayments.size() > 0) {

// Loop through the Payments that fit our criteria and create a new Opportunity that mirrors certain information from the Payment.
for (pymt__PaymentX__c p : completedPayments) {
Opportunity donation = new Opportunity();
donation.Name = p.Name + ' - ' + p.pymt__Amount__c;
donation.CloseDate = date.Today();
donation.StageName = 'Posted';
donation.Amount = p.pymt__Amount__c;
donationList.add(donation);
}

// Insert these new Opportunities (called Donations in NonProfitForce)
try {
insert donationList;
} catch (Dmlexception e) {
System.debug('donationList not inserted: ' + e);
}

// Create two new Lists that will be used to relate the new Opportunities to the Payments in the trigger.
// Select all the opportunities that we just created and order them by Name.  Then select all the Payments that fit our criteria from the trigger
// and order them by Name.  Theoretically, these lists should be the same size and follow the same order since the Names mirror each other..
List <Opportunity> oppList = new List <Opportunity>([Select Id, Name FROM Opportunity WHERE Id IN :donationList ORDER BY Name]);
List <pymt__PaymentX__c> pymtList = new List <pymt__PaymentX__c> ([Select Id, Name FROM pymt__PaymentX__c WHERE Id IN :completedPayments ORDER BY Name]);

//  This loop will assign the opportunity id to the Payment object.
for (Integer i=0; i < pymtList.size(); i++) {
pymtList[i].pymt__Opportunity__c = oppList[i].Id;
}

// Update the list of Payments from above, this should save the Opportunity Id that we just added.
try {
update pymtList;
} catch (Dmlexception e) {
System.debug('pymtList not inserted: ' + e);
}

// Create a new list of Payment objects so we can relate the Contacts to the Opportunities that we just created.
//Since the Payment object is related to both the Contact and Opportunity we can query those Id's directly from the Payment object.
List <pymt__PaymentX__c> listForContRole = new List <pymt__PaymentX__c> ([Select Id, pymt__Contact__r.Id, pymt__Opportunity__r.Id FROM pymt__PaymentX__c WHERE ID IN :completedPayments]);
List <OpportunityContactRole> contRoles = new List<OpportunityContactRole>();

// Loop through this new list of Payment objects.  Create a new OpportunityContactRole and using the Opp and Contact Id's from the Payment object.
for (pymt__PaymentX__C p : listForContRole) {
OpportunityContactRole ocr = new OpportunityContactRole();
ocr.ContactId = p.pymt__Contact__r.Id;
ocr.OpportunityId = p.pymt__Opportunity__r.Id;
contRoles.add(ocr);
}

// Insert this new list of OpportunityContactRoles
try {
insert contRoles;
} catch (DmlException e) {
System.debug('ocrList not inserted: ' + e);
}

} //close if-statement

} //close handleNewPayment method

} //close PaymentManager Class

[/java]

I hope this is helpful, and as always look forward to your feedback.
