如果要使用外部链接，则代码为：
add_action(\'admin_menu\', \'add_custom_link_into_appearnace_menu\');
function add_custom_link_into_appearnace_menu() {
global $submenu;
$permalink = \'http://www.cusomtlink.com\';
$submenu[\'themes.php\'][] = array( \'Custom Link\', \'manage_options\', $permalink );
}
如果要使用呈现自定义链接页
WordPress Administrations Menus 功能则代码为：
add_action(\'admin_menu\', \'add_custom_link_into_appearnace_menu\');
function add_custom_link_into_appearnace_menu() {
add_theme_page(\'Custom Link Pgae Title\', \'Custom Link Menu Title\', \'manage_options\', \'custom-link-unique-identifier\', \'render_custom_link_page\');
}
function render_custom_link_page() {
echo \'Custom Link Page\';
}
