隱形 reCAPTCHA 勾點使用範例

• 在任何表單中加入隱形 reCAPTCHA

  在表單結尾標記前的任何位置插入以下程式碼：
  do_action(‘google_invre_render_widget_action’);

• 驗證表單發佈要求

  $is_valid = apply_filters(‘google_invre_is_valid_request_filter’, true);
  if( ! $is_valid )
  {
  // 在這裡處理錯誤
  }
  else
  {
  // 撰寫網站專屬處理邏輯
  }

• 變更服務徽章/驗證方式語言代碼

  add_filter( ‘google_invre_language_code_filter’, ‘myprefix_change_recaptcha_language’ );
  function myprefix_change_recaptcha_language($language_code){
  $language_code = ‘zh_TW’; // 台灣繁體中文
