Hi, I'm working on creating records using a visualforce page.

I would like the option of creating more than one record (of the same type) if neccessary by adding variables to the class and having declaring them in different columns on the page. It works well, in fact too well! Even if the field is NULL it will create the record.

Here's the class code

public class CreateIABookingController{
    public ItsApproved_Booking__c ItsApprovedBooking {get; set;} //Name the objects as a variables
    public ItsApproved_Product__c ItsApprovedProduct {get; set;}
        //test variables for columns
            public ItsApproved_Product__c ItsApprovedProduct2 {get; set;}
            public ItsApproved_Product__c ItsApprovedProduct3 {get; set;}
        //end of test variables
    
    public ItsApproved_Design__c ItsApprovedDesign {get; set;}
    public ItsApproved_Delivery__c ItsApprovedDelivery {get; set;}
    private string OpportunityId;
    public CreateIABookingController()
    {
        opportunityId = ApexPages.currentPage().getParameters().get('oppId');
        ItsApprovedBooking = new ItsApproved_Booking__c();
        ItsApprovedProduct = new ItsApproved_Product__c();
            //test variables for columns
                ItsApprovedProduct2 = new ItsApproved_Product__c();
                ItsApprovedProduct3 = new ItsApproved_Product__c();
            //end test variables for columns
        ItsApprovedDesign = new ItsApproved_Design__c();
        ItsApprovedDelivery = new ItsApproved_Delivery__c();
    }
    
    public PageReference Save()
    {
        ItsApprovedBooking.Opportunity__c = opportunityId;
        insert ItsApprovedBooking;
        ItsApprovedProduct.Booking_Reference__c = ItsApprovedBooking.Id; //insert the reference field for the parent and declare variable id
        ItsApprovedProduct.Opp__c = opportunityId; //relate the Opp to the Product
        insert ItsApprovedProduct;
            //test for columns
                ItsApprovedProduct2.Booking_Reference__c = ItsApprovedBooking.Id;
                ItsApprovedProduct2.Opp__c = opportunityId;
                insert ItsApprovedProduct2;
                    ItsApprovedProduct3.Booking_Reference__c = ItsApprovedBooking.Id;
                    ItsApprovedProduct3.Opp__c = opportunityId;
                    insert ItsApprovedProduct3;
            //end test for columns
            
        ItsApprovedDesign.Opportunity__c = opportunityId; //relate the Opp to the Design
        ItsApprovedDesign.Product_Reference__c  = ItsApprovedProduct.Id;
        ItsApprovedDelivery.Product__c = ItsApprovedProduct.Id;
        insert ItsApprovedDesign;
        ItsApprovedDelivery.ItsApproved_Design__c  = ItsApprovedDesign.Id;
        ItsApprovedDelivery.Opportunity__c = opportunityId; //relate the Opp to the Delivery
        insert ItsApprovedDelivery;
        
        return new PageReference ('/' + opportunityId);
    }
}

What I'd like to do is add something to the class that will ignore the insert of ItsApprovedProduct2, ItsApprovedProduct3 if they are NULL. I'm guessing that might be an IF isNotEmpty statement around the {get;set;} of the variables? I'm not too sure on the syntax though...
