Redirect logged in users if they are on a specific page

I’m trying to prevent a user access besides the admin to the registeration page and reset password page if they are already logged in. I have the following:

function redirect_loggedin_users() {
// Maybe use is_user_logged_in() instead?
if (!current_user_can('manage_options') && is_page(array(2090, 2092))) {
    wp_redirect(home_url());
            exit();
    }
}
add_action('init', 'redirect_loggedin_users');

I tested it and it’s not working. Can someone please assist me? Thanks.

One problem is that you’re hooking in too early. Reference the Hooks API Action Reference. Template conditionals such as is_page() are only available after the query has been set up and parsed. The earliest action that you can usually safely rely on query conditionals is pre_get_posts. You’re hooking into init, which fires much earlier:

• muplugins_loaded After must-use plugins are loaded
• registered_taxonomy For category, post_tag, etc.
• registered_post_type For post, page, etc.
• plugins_loaded After active plugins and pluggable functions are loaded
• sanitize_comment_cookies
• setup_theme
• load_textdomain For the default domain
• after_setup_theme Generally used to initialize theme settings/options.
• auth_cookie_malformed
• auth_cookie_valid
• set_current_user
• init Typically used by plugins to initialize. The current user is already authenticated by this time.
• widgets_init Used to register sidebars. This is fired at ‘init’, with a priority of 1.
• register_sidebar For each sidebar and footer area
• wp_register_sidebar_widget For each widget
• wp_default_scripts (ref array)
• wp_default_styles (ref array)
• admin_bar_init
• add_admin_bar_menus
• wp_loaded After WordPress is fully loaded
• parse_request Allows manipulation of HTTP request handling (ref array)
• send_headers Allows customization of HTTP headers (ref array)
• parse_query (ref array)
• pre_get_posts Exposes the query-variables object before a query is executed. (ref array)
• posts_selection
• wp After WP object is set up (ref array)
• template_redirect
• get_header
• wp_enqueue_scripts

Given the nature of what you’re trying to do, I would recommend hooking into template_redirect.
