    I have products of specific categories set up. One is a main Membership category and the others have a category of Designation. When someone is on a membership form and they are purchasing a Membership product, they need to be able to purchase 1 or more Designation products. The First designation product they pick should be free, the others are all billed regular price. Is there a way to set this up without the user having to enter a coupon code?

    Hello,

    I am afraid it is not possible to do by default but we can implement custom plugin for you that add such feature.
    Please contact us in helpdesk for details:

    Thank you, I was able to create a calculator that did what I need. But my site also uses a coupon code. Is there a way to ensure that my calculator runs AFTER the calculator for the coupon code?

    I added the code to the site.php file and found my mistake, I was eliminating the coupon discount before looking to see if it exists.

    This calculator checks the current date and if it's October - December, discounts the main membership item by 50%. It checks if there is already a coupon discount (which would be $25% off the membership) and then calculates 50% off that total before applying the end of year discount to the first charge.

    It's important to know that for this website, all memberships go from 4/1 - 4/1. No matter what day they purchase their membership, it has to expire on 4/1 of the next year. This is why they get a 50% discount after October - The date is from the current date to 4/1 of the next year. If they purchase between January 1 and April 1, it goes from 01/01 of the current year until 4/1 of the next year (so they pay full price but get some extra months).

    I have several other hooks in site.php that will update the access record dates and the invoice rebill date.

    It then discounts the first Designation membership item 100%.


    PHP:
    Am_Di::getInstance()->hook->add('invoiceGetCalculators''FSGAinvoiceGetCalculators');

    function 
    FSGAinvoiceGetCalculators(Am_Event $e) {
        
    $vars $e->getVars();
        
    $calculators $e->getReturn();
        
    $calculators[] = new Am_Invoice_Calc_MemberDisc($this->vars);   
        
    $e->setReturn($calculators);

    }

    class 
    Am_Invoice_Calc_MemberDisc extends Am_Invoice_Calc
    {
        
    /** @var Coupon */
        
    protected $coupon;
        protected 
    $user;
        protected 
    $membership_count;
        protected 
    $designation_count;   
        protected 
    $designation_prods;
        
    //Product Category
        //  Designation = 3
        //  Membership = 1
        //  Membership Individual = 6
        //  Membership Organizational = 7
       
        
    public function productInCategory($category_id$product_id){
            
    $rows AM_di::getInstance()->db->query("SELECT product_id FROM ?_product_product_category
                WHERE product_category_id = ? and product_id = ?"
    $category_id$product_id);
            return !empty(
    $rows);
        }
        public function 
    calculate(Invoice $invoiceBill)
        {

    Yes, I found the error in my code. This line:
    Code:
    $this->membership_count = $this->designation_count = 0;
    was zeroing out the coupon discount. Once I removed that line of code it did what I needed it to do.

    Thanks for your help.
