Display in GraphQL values from multiple products

Question

I am trying to load in graphql product details. I am only managing to get the details of one product $json['Transaction']['OrderItems'][0] but I would like to get the values for all the products which are in $json['Transaction']['OrderItems']. In resolver I have:

return [
        'cart' => [
            'products' => [
                'sku' => $json['Transaction']['OrderItems'][0]['ItemCode'],
                'quantity' => $json['Transaction']['OrderItems'][0]['ItemQuantity'],
                'price' => $json['Transaction']['OrderItems'][0]['ItemQuantity']
            ],
]

in schema.graphqls I have:

type AddProductsToCartOutput {
products: ITEMS
}


type ITEMS {
sku: String!
quantity: Float!
price: Float!
}

in the request:

   cart {
  
products {
    sku
    quantity
    price
}
}

and in the output I am getting:

"cart": {
    "products": {
      "sku": "33150220000",
      "quantity": 5,
      "price": 5
    },
 }

But I need to show all the items!

Answer 1

In order to pass multiple items data to graphql output you will have to define the ITEMS as array in your schema.graphqls

Try changing with below code

type AddProductsToCartOutput {
    products: [ITEMS]
}

Thanks!
