我在“主题选项”页面上有四个字段。在本地开发环境中，所有四个都保存输入值，将其保留在页面重载中，然后将值吐出到主题模板本身中。
但是，当这些更改被推送到登台服务器时。只有一个字段（最后一个字段）保存该值，保留它并在主题本身中吐出该值。
我在做什么错了？
这是我的theme-options.php所包含的functions.php的内容：
<?php
function add_new_menu_items()
{
//add a new menu item. This is a top level menu item i.e., this menu item can have sub menus
add_menu_page(
"Theme Options", //Required. Text in browser title bar when the page associated with this menu item is displayed.
"Theme Options", //Required. Text to be displayed in the menu.
"manage_options", //Required. The required capability of users to access this menu item.
"theme-options", //Required. A unique identifier to identify this menu item.
"theme_options_page", //Optional. This callback outputs the content of the page associated with this menu item.
"", //Optional. The URL to the menu item icon.
100 //Optional. Position of the menu item in the menu.

}
