collectionByHandle is not working with variable

[atikju]

What am I missing here? See my codes below:

$collection_handle = "my-handle";

$graphQL = <<<Query
query {
  collectionByHandle(handle: \$handle) {
    products(first: 30) {
      edges {
        node {
          images(first: 1) {
            edges {
              node {
                src
              }
            }
          }
          handle
          variants(first: 10) {
            edges {
              node {
                compareAtPrice
                price
              }
            }
          }
        }
      }
    }
  }
}
Query;

$variables = [
    "handle" => $collection_handle
];

@atikju Can you show the rest of the code, where you are making the final call?

I'm just doing this:

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

echo "<pre>";
var_dump($data["data"]);
echo "</pre>";

Try this

$graphQL = <<<Query
query(\$handle: String!) {
  collectionByHandle(handle: \$handle) {
    products(first: 30) {
      edges {
        node {
          images(first: 1) {
            edges {
              node {
                src
              }
            }
          }
          handle
          variants(first: 10) {
            edges {
              node {
                compareAtPrice
                price
              }
            }
          }
        }
      }
    }
  }
}
Query;
