如何将redirect_to从登录传递到Wordpress中的注册页面

Question

I'm trying to pass the redirect_to querystring to the registration page so individuals who don't have a login, need to register, get redirected back to login page's referrer. I used

wp_login_url(get_permalink($event->get_id())) 

to add the redirect_to querystring to the login page, and tried to use get get_query_var( 'redirect_to' ), but nothing happens.

Anyone know how to add the login querystring on redirect to the register page?

If you're looking to maintain the redirect_to url from the login to the registration and back to the login page, so the user can just enter their password once received by email, and still return to the original referrer this is the full solution.

function custom_register_url( $registration_url ) {
    $redirect_to = $_GET["redirect_to"];
    $eab_msg = $_GET["eab"];

    if( $redirect_to != "" && $eab_msg != ""  ) {
        // change query name values to prevent default behaviour (redirect_to to uct_redirect)
        $registration_url = sprintf( '<a href="%s&%s&%s">%s</a>', esc_url( wp_registration_url() ), "uct_redirect=" . urlencode($redirect_to), "uct_eab=" . urlencode($eab_msg), __( 'Register' ) );
    }

    return $registration_url;
}
add_filter( 'register', 'custom_register_url' );

function custom_registration_redirect($registration_redirect) {
    $redirect_to = $_GET["uct_redirect"];
    $eab_msg = $_GET["uct_eab"];

    if( $redirect_to != "" && $eab_msg != ""  ) {
        // change query names back to original values (uct_redirect to redirect_to)
        $registration_redirect = wp_login_url( $redirect_to ) . '&eab=' . $eab_msg;
    }

    return $registration_redirect;
}
add_filter( 'registration_redirect', 'custom_registration_redirect' );

Just drop it in functions.php. Hope this helps someone Cheers!
