Explanation

If you want to stop new users from signing up on your WordPress site, here's a simple way to do it.

Disable Registration Option:

The code automatically turns off the "Anyone can register" setting in your WordPress General Settings. This means no new users can sign up.

Remove Registration Link:

It also removes the registration link from the login page, so visitors won't see an option to register.

Redirect Registration Page:

If someone tries to access the registration page directly, they'll be redirected to your homepage instead.

With these changes, your site will no longer allow new user registrations, keeping your community exclusive or private as needed.

Code
// Function to disable new user registration in WordPress
function wp_dudecom_disable_user_registration() {
    // Remove the 'Anyone can register' option from the General Settings
    update_option('users_can_register', 0);
}

// Hook the function to 'init' to ensure it runs on every page load
add_action('init', 'wp_dudecom_disable_user_registration');

// Function to remove the registration link from the login form
function wp_dudecom_remove_register_link($link) {
    // Check if the link is for registration and return an empty string if true
    if (strpos($link, 'wp-login.php?action=register') !== false) {
        return '';
    }
    return $link;
}

// Hook the function to 'register' filter to modify the registration link
add_filter('register', 'wp_dudecom_remove_register_link');

// Function to redirect users trying to access the registration page
function wp_dudecom_redirect_registration_page() {
    // Check if the current page is the registration page
    if (isset($_GET['action']) && $_GET['action'] === 'register') {
        // Redirect to the home page
        wp_redirect(home_url());
        exit;
    }
}

// Hook the function to 'login_init' to check for registration page access
add_action('login_init', 'wp_dudecom_redirect_registration_page');
