注意

• This function is a simple wrapper for a call to add_submenu_page(), passing the received arguments and specifying ‘themes.php’ as the $parent_slug argument. This means the new page will be added as a sub menu to the Appearance menu.
• The $capability parameter is used to determine whether or not the page is included in the menu based on the Roles and Capabilities) of the current user.
• The function handling the output of the options page should also verify the user’s capabilities.
