Typical usage occurs in a function registered with the 'admin_menu' hook (see Adding Administration Menus):

 * wordpress之魂 © http://wphun.com
 * ---------------------------------- */

add_action('admin_menu', 'my_plugin_menu');

function my_plugin_menu() {
	add_options_page('My Options', 'My Plugin', 'manage_options', 'my-plugin.php', 'my_plugin_page');
}

Object Oriented options page helper / view:

/* ----------------------------------
 * wordpress之魂 © http://wphun.com
 * ---------------------------------- */

class options_page {
	function __construct() {
		add_action( 'admin_menu', array( $this, 'admin_menu' ) );
	}
	function admin_menu () {
		add_options_page( 'Page Title','Circle Tree Login','manage_options','options_page_slug', array( $this, 'settings_page' ) );
	}
	function  settings_page () {
		echo 'This is the page content';
	}
}
new options_page;

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.
