GraphQL and PHPShopify SDK

[Jamessy]

Hi

I'm using PHPShopify to send GraphQL queries and mutations to my dev shop.

The following code is to deactivate a discount code, using GraphQL and the PHPShopify library

          $graphQL = <<<Query
          mutation discountCodeDeactivate($id: ID!) {
                    discountCodeDeactivate(id: $id) {
                      userErrors {
                        field
                        message
                      }
                    }
                  }
          Query;

          $variables = [
            "input" => [
              "id" => '12345'
            ]
          ];

I keep getting the following error

 Uncaught PHPShopify\Exception\ApiException: message - Parse error on ":" (COLON) at [1, 33],

I know it's because of the variable, but can't figure out why. I've tried swapping $id to $input but it's the same error.

Any ideas why?

Hey @Jamessy, 

To be sure I did some testing to confirm expected functionality of the Discount API, and using Insomnia had success with all attempts of the discountCodeDeactivate mutation. While not a seasoned PHP developer myself, you mentioned it likely being related to the variable ("id" input), and the shared request looks to be using  ' ' instead of " "  - all documented examples I was able to find use the latter, so it could just be formatting. 

Beyond that, if you are still consistently getting errors, opening an issue in the Github of library being used is going to be the best next step. Should you need, this is the recently released official Shopify PHP Library - GitHub and here are some third party libraries listed in our API resources.

- Cheers!

You need to escape the $id with a "/".

$graphQL = <<<Query
          mutation discountCodeDeactivate(/$id: ID!) {
                    discountCodeDeactivate(id: /$id) {
                      userErrors {
                        field
                        message
                      }
                    }
                  }
          Query;
