WordPress中修改woocommerce结算页面去掉其它表单字段

通过添加 woocommerce_shared_settings 过滤器，修改表单内容。

add_filter('woocommerce_shared_settings', function ($settings) {
  $settings['defaultFields']['email']['required'] = false;
  $settings['defaultFields']['email']['hidden'] = true;

  $settings['defaultFields']['last_name']['required'] = false;
  $settings['defaultFields']['last_name']['hidden'] = true;

  $settings['defaultFields']['company']['required'] = false;
  $settings['defaultFields']['company']['hidden'] = true;

  $settings['defaultFields']['country']['required'] = false;
  $settings['defaultFields']['country']['hidden'] = true;

  $settings['defaultFields']['city']['required'] = false;
  $settings['defaultFields']['city']['hidden'] = true;

  $settings['defaultFields']['state']['required'] = false;
  $settings['defaultFields']['state']['hidden'] = true;

  $settings['defaultFields']['postcode']['required'] = false;
  $settings['defaultFields']['postcode']['hidden'] = true;

  return $settings;
});

其中，参数 $settings 会返回woocommerce的完整配置信息

我们只需要关心 $settings 内部的数组 defaultFields 内容。

默认 $settings['defaultFields'] 包含以下内容：
