GraphQL Variables Suggestion

[wardwj]

Error: Notice: Undefined variable: input

$calculatedOrderId = $data['data']['orderEditBegin']['calculatedOrder']['id'];

$graphQL = <<<Query
mutation addVariantToOrder($input: OrderInput!){
  orderEditAddVariant(input: $input){
    calculatedOrder {
      id
      addedLineItems(first:5) {
        edges {
          node {
            id
            quantity
          }
        }
      }
    }
    userErrors {
      field
      message
    }
  }
}
Query;
        
$variables = [
  "input" => [
    "id" => $calculatedOrderId,
    "variantId" => "gid://shopify/ProductVariant/33346521235509",
    "quantity" => 1
  ]
];

$data = $shopify->GraphQL->post($graphQL, null, null, $variables);

Also having no joy with the example.

Could someone explain how the variables work when they are not in an array?

Problem resolved, the variables in the query where being executed and was causing data to be added directly in to the query. Fix included escaping the variable by using \$ID. Would be a great reference to use in the readme for people who encounter the same problem.

$graphQL = <<<Query
mutation addVariantToOrder(\$id: ID!, \$variantId: ID!, \$quantity: Int!){
  orderEditAddVariant(id: \$id, variantId: \$variantId, quantity: \$quantity){
    calculatedOrder {
      id
      addedLineItems(first:5) {
        edges {
          node {
            id
            quantity
          }
        }
      }
    }
    userErrors {
      field
      message
    }
  }
}
Query;

$variables = [
  "id" => "gid://shopify/CalculatedOrder/3574530101",
  "variantId" => "gid://shopify/ProductVariant/33346521235509",
  "quantity" => 1
];

$data = $shopify->GraphQL->post($graphQL, null, null, $variables);

I agree, this threw me off as well! A small notice in the GraphQL section would be great.

example: $ may need to be escaped when using heredoc syntax

$graphQL = <<<Query
    mutation (\$input: CustomerInput!) {
        customerCreate(input: \$input)
        {
            customer {
                id
                displayName
            }
            userErrors {
                field
                message
            }
        }
    }
Query;
