所以解决方案其实很简单。

首先，我需要修改我的自定义成员登录重定向，以便在重定向URL中包含redirect\\u to部分：

function pb4r_redirect()
{
    global $current_user;
    $refer=urlencode($_SERVER["REQUEST_URI"]);
    $okay_pages = array(4, 10, 12, 13, 191, 200, 1380, 1381, 1382, 1383, 1449, 1631, 1643, 1652, 1653, 1654, 1666, 1718, 1725, 1840, \'Checkout\', \'Cart\', pmpro_getOption(\'billing_page_id\'), pmpro_getOption(\'account_page_id\'), pmpro_getOption(\'levels_page_id\'), pmpro_getOption(\'checkout_page_id\'), pmpro_getOption(\'confirmation_page_id\'));

   //if the user is logged out

 if(!$current_user->ID
     && !is_home()
     && !is_page($okay_pages)
     && !strpos($_SERVER[\'REQUEST_URI\'], "login")
     && !is_singular( \'post\' )
     && !is_product()
    )
    {
        wp_redirect( \'/member-login\' . \'?redirect_to=\' . $refer );
        exit;
    } 
}
add_action(\'template_redirect\', \'pb4r_redirect\');

function wc_custom_user_redirect( $redirect, $user ) {
    // Get the first of all the roles assigned to the user
global $current_user;

    $level = pmpro_getMembershipLevelForUser($user->ID);
    $myaccount = get_permalink( wc_get_page_id( \'myaccount\' ) );

if( isset( $_REQUEST[\'redirect_to\'] ) ) {
        return $_REQUEST[\'redirect_to\'];
}elseif      ( $level->id == 2 ) {
            $redirect = \'/rookie-dashboard/\';
} elseif    ( $level->id == 3 ) {
            $redirect = \'/player-dashboard/\';
} elseif    ( $level->id == 4 ) {
            $redirect = \'/all-star-dashboard/\';
} elseif    ( $level->id == 5 ) {
            $redirect = \'/coach-dashboard/\';
} elseif    ( $level->id == 6 ) {
            $redirect = \'/owner-dashboard/\';
} elseif    ( $level->id == 7 ) {
            $redirect = \'https://corporate.example.com/dashboard/\';
} elseif    ( $level->id == 8 ) {
            $redirect = \'/dashboard/\';

} else {
    $redirect = $myaccount;
}
    return $redirect;
}
add_filter( \'woocommerce_login_redirect\', \'wc_custom_user_redirect\', 10, 2 );
