Activating / Using

You can install and activate the plugin like any WordPress plugin. Download the .zip from Github and add to your plugins directory, then activate.

Once the plugin is active, the Upload scalar type will be available to your mutation input fields.

composer require dre1080/wp-graphql-upload

Usage

Then you can start using in your mutations like so:

register_graphql_mutation(
  'upload', [
      'inputFields' => [
          'file' => [
              'type' => ['non_null' => 'Upload'],
          ],
      ],
      'outputFields' => [
          'text' => [
              'type'    => 'String',
              'resolve' => function ($payload) {
                  return $payload['text'];
              },
          ],
      ],
      'mutateAndGetPayload' => function ($input) {
          if (!function_exists('wp_handle_sideload')) {
              require_once(ABSPATH . 'wp-admin/includes/file.php');
          }

          wp_handle_sideload($input['file'], [
              'test_form' => false,
              'test_type' => false,
          ]);

          return [
              'text' => 'Uploaded file was "' . $input['file']['name'] . '" (' . $input['file']['type'] . ').',
