add_options_page() 示例

注意

  • This function is a simple wrapper for a call to add_submenu_page(), passing the received arguments and specifying 'options-general.php' as the $parent_slug argument. This means the new options page will be added as a sub menu to the Settings 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.
  • If there are spaces in the slug, then these will be stripped out when the URL is generated. This will result in an error message telling you that you do not have sufficient permissions to view the page.
