php代碼優化的WordPress導航菜單

Question

我做了一個功能，插入導航菜單到我的WordPress主題。我會喜歡你的建議，如何使它更好，也許更小。它是：

function cosmos_nav_menu($theme_location, $type) { 

switch ($type) { 

case 'basic-tabs' : 
    $menu_class = 'nav nav-tabs'; 
    $wrap_before = ''; 
    $wrap_after = ''; 
    break; 
case 'stacked-tabs' : 
    $menu_class = 'nav nav-tabs nav-stacked'; 
    $wrap_before = ''; 
    $wrap_after = ''; 
    break; 
case 'basic-pills' : 
    $menu_class = 'nav nav-pills'; 
    $wrap_before = ''; 
    $wrap_after = ''; 
    break; 
case 'stacked-pills' : 
    $menu_class = 'nav nav-pills nav-stacked'; 
    $wrap_before = ''; 
    $wrap_after = ''; 
    break; 
case 'list' : 
    $menu_class = 'nav nav-list'; 
    $wrap_before = ''; 
    $wrap_after = ''; 
    break; 
case 'navbar' : 
    $menu_class = 'nav'; 
    $wrap_before = "<div class=\"navbar\">\n<div class=\"navbar-inner\">\n<div class=\"container\">\n"; 
    $wrap_before .= "<a class=\"btn btn-navbar\" data-toggle=\"collapse\" data-target=\".nav-collapse\">\n"; 
    $wrap_before .= "<span class=\"icon-bar\"></span>\n<span class=\"icon-bar\"></span>\n<span class=\"icon-bar\"></span>\n</a>\n"; 
    $wrap_before .= "<div class=\"nav-collapse\">\n"; 
    $wrap_after = "\n</div>\n</div>\n</div>\n</div>"; 
    break; 
case 'navbar-brand' : 
    $menu_class = 'nav'; 
    $wrap_before = "<div class=\"navbar\">\n<div class=\"navbar-inner\">\n<div class=\"container\">\n"; 
    $wrap_before .= "<a class=\"btn btn-navbar\" data-toggle=\"collapse\" data-target=\".nav-collapse\">\n"; 
    $wrap_before .= "<span class=\"icon-bar\"></span>\n<span class=\"icon-bar\"></span>\n<span class=\"icon-bar\"></span>\n</a>\n"; 
    $wrap_before .= "<a class=\"brand\" href=\"" . home_url('/') . "\">" . esc_html(get_bloginfo('name', 'display')) . "</a>\n"; 
    $wrap_before .= "<div class=\"nav-collapse\">\n"; 
    $wrap_after = "\n</div>\n</div>\n</div>\n</div>"; 
    break; 
} 

echo $wrap_before; 

wp_nav_menu(array(
'theme_location' => $theme_location, 
'container' => false, 
'menu_class' => $menu_class, 
'walker' => new Bootstrap_Walker() 
)); 

echo $wrap_after; 
} 

它基本上是wordpress'wp_nav_menu（）函數的一個包裝。它在基於$ type變量調用wp_nav_menu（）函數之前和之後添加了一些html代碼。前五個例子的前後代碼都沒有。在過去的兩種情況下，代碼重複也相當多。我還想包括一個情況，其中賦予$ type變量的字符串不匹配任何情況並根據回顯消息。

我最初用很多「if」語句代替「case」來編寫這個函數，但是他們中的任何一個對我都沒有好看。

任何幫助將不勝感激。

我會設置默認wrap_before和wrap_after，是這樣的：

$wrap_before = ''; 
$wrap_after = ''; 

switch ($type) 
{ 
    case 'basic-tabs' : 
     $menu_class = 'nav nav-tabs'; 
     break; 
    case 'basic-tabs' : 
     $menu_class = 'nav nav-tabs nav-stacked'; 
     break; 
}
