自定义字段未保存

问题描述

我尝试通过使用WPGraphQL向用户添加自定义用户字段。因此，我尝试在官方WPGraphQL文档https://docs.wpgraphql.com/extending/fields/#register-fields-to-the-schema中重新创建示例：

add_action('graphql_init',function () {
  $hobbies = [
    'type'        => ['list_of' => 'String'],'description' => __('Custom field for user mutations','your-textdomain'),'resolve'     => function ($user) {
      $hobbies = get_user_Meta($user->userId,'hobbies',true);
      return !empty($hobbies) ? $hobbies : [];
    },];

  register_graphql_field('User',$hobbies);
  register_graphql_field('createuserInput',$hobbies);
  register_graphql_field('UpdateUserInput',$hobbies);
});

我已经将类型从\WPGraphQL\Types::list_of( \WPGraphQL\Types::string() )更改为['list_of' => 'String']。

如果我现在执行updateUser突变，我的兴趣爱好就不会更新。我在干什么错？

突变：

mutation MyMutation {
  __typename
  updateUser(input: {clientMutationId: "tempId",id: "dXNlcjox",hobbies: ["football","gaming"]}) {
    clientMutationId
    user {
      hobbies
    }
  }
}

输出：

{
  "data": {
    "__typename": "RootMutation","updateUser": {
      "clientMutationId": "tempId","user": {
        "hobbies": []
      }
    }
  }
}

解决方法

感谢xadm，我唯一忘记的是真正改变了这个领域。我对文件有点困惑，我的错。 （我真的是WPGraphQL btw的新手）

这是必须添加的内容：

add_action('graphql_user_object_mutation_update_additional_data','graphql_register_user_mutation',10,5);

function graphql_register_user_mutation($user_id,$input,$mutation_name,$context,$info)
{
  if (isset($input['hobbies'])) {
    // Consider other sanitization if necessary and validation such as which
    // user role/capability should be able to insert this value,etc.
    update_user_meta($user_id,'hobbies',$input['hobbies']);
  }
}
