如何将整个WordPress网站限制为访问者，但注册和登录页面？

Question

Restrict Website, But Login and Register Page

---

I want my my entire WordPress site to be restricted to visitors, but I want the register and login page to be accessible (not restricted) to the visitors

Since my website is a members-only website, I want to restrict it's access so that visitors only see 2 pages, the login page and the register page.

I have tried multiple plugins to do exactly that but unfortunately for me, I haven't been able to find the right one. Some plugins redirect the entire website to one page while other plugins require custom redirection settings for each page to be separately added.

What I want:-

1. Restrict entire WordPress website to visitors by redirection.
2. Do not restrict 2 pages, Login Page and Registration Page.
3. Redirect Users to Login Page and/or Register Page.

There is an option in my Login Page to view the Register Page.
I want both of these pages to be accessible to the visitor and the rest of the website to be inaccessible.

You can simply redirect your users using template_redirect hook

add_action( 'template_redirect', 'redirect_users' );
function redirect_users( $template ) {
    if ( !is_user_logged_in() ) {
        if ( !is_page( 'register page ID' ) ) {
            wp_redirect( wp_login_url() );
        }
    }

    return $template;
}

You need to add register and login page IDs and login page URL in the function.
