       'country_list'  => '', 
       'flags'   => '', 
       'country_details' => '', 
       'country_currency' => '',

       'city_list'  => '' 
      ), $_POST); 

任何人能告诉我是什么短码我应该写信给所有国家的名字在一个页面上？

你可以重新写你的函数像这样

add_shortcode('save_details', function($atts) { 
     global $post; 

     $post_vars = array(
      'country_code'  => '', 
      'country_list'  => '', 
      'flags'   => '', 
      'country_details' => '', 
      'country_currency' => '', 
      'currency_symbol' => '', 
      'currency_html' => '', 
      'currency_code' => '', 
      'city_list'  => '' 
     ); 
     extract(shortcode_atts($post_vars, $atts)); 
     // country_code is now available like so $country_code 
     // return data after your done 

}); 

和访问它像这样

//all of your attributes can be used inside the sq brackets 
[save_details] and [save_details country_code = "" country_list = ""]
