Hi,

New to Apex. Any suggestions on how to bulkify this code?

====

/* Provide summary of Number of Contacts on Account record */

trigger ContactSumTrigger on Contact (after insert) {

try {
// Turn DB off.
CRMfusionDBR101.DB_Globals.triggersDisabled = true;

System.debug('########## Entering ContactSumTrigger');
Contact[] cons;
if (Trigger.isDelete)
cons = Trigger.old;
else
cons = Trigger.new;

// get list of accounts
Set<ID> acctIds = new Set<ID>();
for (Contact con : cons) {
acctIds.add(con.AccountId);
}

Map<ID, Contact> contactsForAccounts = new Map<ID, Contact>([select Id
,AccountId
from Contact
where AccountId in :acctIds]);

Map<ID, Account> acctsToUpdate = new Map<ID, Account>([select Id
,Number_of_Contacts__c
from Account
where Id in :acctIds]);

for (Account acct : acctsToUpdate.values()) {
Set<ID> conIds = new Set<ID>();
for (Contact con : contactsForAccounts.values()) {
if (con.AccountId == acct.Id)
conIds.add(con.Id);
}
if (acct.Number_of_Contacts__c != conIds.size())
acct.Number_of_Contacts__c = conIds.size();
}

update acctsToUpdate.values();
System.debug('########## Exiting ContactSumTrigger'); }
catch(Exception e) {
system.debug ('error: '+e.getMessage() );
}

// Turn DB back on.
CRMfusionDBR101.DB_Globals.triggersDisabled = false;

}
