wordpress - WordPressリダイレクトログイン/ログアウト

Question

メニューにログインを追加するスクリプトがあります。しかし、ログインした後、正しくリダイレ​​クトされません。ログイン後にログインページの前のページにリダイレクトしたい。

function sv_get_logout_redirect_url() {
    $badurls = array('submit-form', 'dashboard', 'profile', 'guidelines');
    $current_url = get_permalink();
    $isgood = true;
    foreach ($badurls as $bad) {
        $pos = strpos($current_url,$bad);
        if (! $pos === false) {
            $isgood = false;
            break;  // no need to check any more "bads"
        }
    }
    if ($isgood) {
        return wp_logout_url(get_permalink());
    } else {
        return wp_logout_url(home_url());
    }
}

add_filter( 'wp_nav_menu_items', 'sv_add_usermenu', 10, 2 );

function sv_add_usermenu( $items, $args ) {
    global $current_user;

    if (is_user_logged_in() && $args->theme_location == 'primary-menu') {
        // menu items for logged in user
        $guidelines_url = site_url() . '/guidelines/';
        $dashboard_url = site_url() . '/dashboard/' . $current_user->user_nicename;
        $profile_url = site_url() . '/profile/' . $current_user->user_nicename; 

        //  http://fortawesome.github.com/Font-Awesome/
        //  some fontawesome names icon-arrow-down, icon-chevron-down, icon-caret-down
        $items .= "<li class='menu-item'><a href='#'>$current_user->display_name <span class='icon-caret-down'> </span> </a>";
        //$items .= "<li class='menu-item'><a href='#'>$current_user->display_name</a>";
        $items .= "<ul>";
        $items .= "<li class='sub-menu'><a href='$guidelines_url'>Usage Guidelines</a></li>";
        $items .= "<li class='sub-menu'><a href='$dashboard_url'>My Dashboard</a></li>";
        $items .= "<li class='sub-menu'><a href='$profile_url'>My Profile</a></li>";
        $items .= "<li class='sub-menu'><a href='" . sv_get_logout_redirect_url()  . "'>Uitloggen</a></li>";
        $items .= "</ul>";
        $items .= "</li>";
    } elseif (!is_user_logged_in() && $args->theme_location == 'primary-menu') {
        //menu items for NOT logged in user
        //$login_url = site_url('/a-page-name/');       // get login url and redirect to a specific page
        //$login_url = wp_login_url( home_url() );      // get login url and redirect to home page
        $login_url = wp_login_url( get_permalink() );   // get login url and redirect to current page
        //the contents of <a href""  must be a url
        $items .= "<li class='sub-menu'> <a href='$login_url' class='simplemodal-login'>Log In</a></li>";
    }
    return $items;
}

誰かが私を助けてくれることを願っています！ありがとう。
