How to Make Promotional Codes Applicable on Tickets During Ordering in Open Event Frontend

This blog illustrate how to enable application of promotional codes on tickets during ordering tickets in Open Event Frontend to avail discounts and access to special tickets. Open event allows organizers to add some promotional codes on some tickets, which can be used by users to avail additional offers on tickets while ordering. Promotional codes can be of three types:

  1. Discount Codes: Allows customers to buy a ticket at discounted rates.
  2. Access Codes: Allows customers to access some hidden tickets which are accessible only to special customers.
  3. Discount + Access Code: Allows customer to access special tickets and avail discount at the same time.

Creating a discount/access code:

Organizers and admin can create an access code or a discount code from the event dashboard. They can specify the validity period of the code and can also specify the tickets on which the code will be applicable.

Validating promotional code after user enters the code:

User is allowed to enter the promotional code on events page upon selecting the tickets. IF promotional code is valid then suitable discount is provided on applicable tickets and if promotional code is an access code then hidden tickets for which the promotional code is valid are shown.

To check the validity of the promotional code we deal with the following APIs on the open event server:

  • GET             /v1/discount-codes/{Code}              (For Discount code)
  • GET             /v1/access-codes/{Code}                  (For Access code)

Code snippet to check the validity for access code is given below:

let promotionalCode = this.get('promotionalCode');
 let order = this.get('order');
   try {
     let accessCode = await this.get('store').findRecord('access-code', promotionalCode, {});
     order.set('accessCode', accessCode);
     let tickets = await accessCode.get('tickets');
     tickets.forEach(ticket => {
     ticket.set('isHidden', false);
     this.get('tickets').addObject(ticket);
     this.get('accessCodeTickets').addObject(ticket);
     this.set('invalidPromotionalCode', false);
  });
  } catch (e) {
     this.set('invalidPromotionalCode', true);
  }

Similarly for discount code we fetch the details of the discount code via the api and then validate the code. After the validation we apply the discount to the tickets applicable. Code snippet for the discount code part is given below:

try {
  let discountCode = await this.get('store').findRecord('discount-code', promotionalCode, { include: 'tickets' });
  let discountType = discountCode.get('type');
  let discountValue = discountCode.get('value');
  order.set('discountCode', discountCode);
  let tickets = await discountCode.get('tickets');
  tickets.forEach(ticket => {
     let ticketPrice = ticket.get('price');
     if (discountType === 'amount') {
       ticket.set('discount', Math.min(ticketPrice, discountValue));
       this.get('discountedTickets').addObject(ticket);
     } else {
       ticket.set('discount', ticketPrice * (discountValue / 100));
       this.get('discountedTickets').addObject(ticket);
     }
     this.set('invalidPromotionalCode', false);
  });
} catch (e) {
   if (this.get('invalidPromotionalCode')) {
      this.set('invalidPromotionalCode', true);
   }
}

After promotional codes are verified we apply them to the selected tickets. In this way we apply the promotional codes to the tickets.
