Shipping and payment information ​

WARNING

Please remember that payment and shipping methods shouldn't be cached. It is important to refresh data before displaying it.

Before fetching, ensure the cart is not empty by using refreshCart in the useCart composable.

Get shipping methods

ts
const { getShippingMethods } = useCheckout();

await getShippingMethods();

vue
<script setup lang="ts">
const {
  shippingMethods,
  setShippingMethod,
  selectedShippingMethod: shippingMethod,
  getShippingMethods,
} = useCheckout();

const selectedShippingMethod = computed({
  get(): string {
    return shippingMethod.value?.id || "";
  },
  async set(shippingMethodId: string) {
    await setShippingMethod({ id: shippingMethodId });
  },
});
</script>
<template>
  <div v-for="shippingMethod in shippingMethods" :key="shippingMethod.id">
    <input
      :id="shippingMethod.id"
      v-model="selectedShippingMethod"
      :value="shippingMethod.id"
      name="shipping-method"
      type="radio"
    />
    <label :for="shippingMethod.id">
      {{ shippingMethod.name }}
    </label>

    return paymentMethod.value?.id || "";
  },
  async set(paymentMethodId: string) {
    await setPaymentMethod({ id: paymentMethodId });
  },
});
</script>
<template>
  <div v-for="paymentMethod in paymentMethods" :key="paymentMethod.id">
    <input
      :id="paymentMethod.id"
      v-model="selectedPaymentMethod"
      :value="paymentMethod.id"
      name="payment-method"
      type="radio"
    />
    <label :for="paymentMethod.id">
      {{ paymentMethod.name }}
    </label>
  </div>
</template>

Personal information ​

Each guest user has to provide billing data. Those data will be used to create a standard or temporary account.

vue
<script setup lang="ts">
const state = reactive({
  salutationId: "",
  firstName: "",
  lastName: "",
  email: "",
  password: "",
  guest: false,
  billingAddress: {
    street: "",
    zipcode: "",
    city: "",
    countryId: "",
  },
});
const { register } = useUser();
const { getCountries } = useCountries();
const { getSalutations } = useSalutations();
const invokeSubmit = () => {
  register(state);
};
</script>
<template>
  <form
    id="checkout-billing-address"
    name="checkout-billing-address"
    method="post"
    @submit.prevent="invokeSubmit"
  >
    <label for="salutation">Salutation</label>
    <select id="salutation" v-model="state.salutationId" name="salutation">
      <option disabled selected value="">Choose salutation...</option>
      <option
        v-for="salutation in getSalutations"
        :key="salutation.id"
        :value="salutation.id"
      >
        {{ salutation.displayName }}
      </option>
    </select>

    <label for="first-name">First name</label>
    <input
      id="first-name"
      v-model="state.firstName"
      type="text"
      name="first-name"
    />

    <label for="last-name">Last name</label>
    <input
      id="last-name"
      v-model="state.lastName"
      type="text"
      name="last-name"
    />

    <input id="create-account" v-model="state.guest" type="checkbox" />
    <label for="create-account">Do not create a customer account.</label>

    <label for="email-address">Email address</label>
    <input
      id="email-address"
      v-model="state.email"
      type="email"
      name="email-address"
    />

    <div v-if="!state.guest">
      <label for="password">Password</label>
      <input

    />

    <label for="postal-code">ZIP / Postal code</label>
    <input
      id="postal-code"
      v-model="state.billingAddress.zipcode"
      type="text"
      name="postal-code"
    />

      </option>
    </select>

Order summary ​

We can use some helper methods from useCart composable to display an order summary and format prices.

Refer to formatting prices for more information on displaying prices.

WARNING

Totals should not be calculated by the frontend. All calculations should be done on the backend side.

vue
<script setup lang="ts">
const { refreshCart, cartItems, subtotal, totalPrice, shippingTotal } =
  useCart();
const { getFormattedPrice } = usePrice();
await refreshCart();
</script>
<template>
  <div>
    <div>
      <p>Subtotal</p>
      <p>{{ getFormattedPrice(subtotal) }}</p>
    </div>
    <div>
      <p>Shipping estimate</p>
      <p>{{ getFormattedPrice(shippingTotal) }}</p>
    </div>
    <div>
      <p>Order total</p>
      <p>{{ getFormattedPrice(totalPrice) }}</p>
    </div>
  </div>
</template>

Place an order ​

Placing an order requires

  • A valid shipping address
  • A selected payment method
  • A selected shipping method

After placing an order with the createOrder method, the cart is refreshed automatically.

ts
const { createOrder } = useCheckout();

const order = await createOrder();

After creating an order, you can fetch order data. orderId is returned by the createOrder method from the useCheckout composable. The backend allows fetching orders related only to the current user by checking the session.

ts
const {
  loadOrderDetails,
  personalDetails,
  billingAddress,
  shippingAddress,
  order,
} = useOrderDetails({ order: { id: orderId } as any });

await loadOrderDetails();
