下拉菜单不工作代码点火器控制器

Question

我的下拉菜单和控制器有一个小问题，我的控制器上有下拉内容的变量，但它不会显示在网页上，只有这3个不起作用{$DEN}、{$DPT}和{$DES}

这是HMTL

<div class="top-nav">
<nav class="navbar navbar-default">
<div class="container">
<button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1">Menu                       
</button>
<!-- Collect the nav links, forms, and other content for toggling -->

<div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
<ul class="nav navbar-nav">
<img src="{$favlogo}" alt="" width="8%" height="auto">
<li class="hvr-bounce-to-bottom active">{$homebar}</li>
<li class="hvr-bounce-to-bottom">{$aboutUs}</li>
<li class="hvr-bounce-to-bottom">{$servicos}</li>
<li class="hvr-bounce-to-bottom">{$galeria}</li>
<li class="hvr-bounce-to-bottom">{$equipa}</li>
<li class="hvr-bounce-to-bottom">{$contactUs}</li>
<li class="hvr-bounce-to-bottom">{$user}</li>
<li class="hvr-bounce-to-bottom">{$login}</li>
<li class="hvr-bounce-to-bottom">{$logout}</li>
<li class="hvr-bounce-to-bottom">{$email}</li>
<li class="hvr-bounce-to-bottom">{$contacto}</li>
<li class="dropdown">
<a href="javascript:void(0)" class="dropbtn">Idioma</a>
<div class="dropdown-content">
{$DEN}
{$DPT}
{$DES}
</div>
</li>
</ul>   
<div class="clearfix"> </div>
</div>  
</div>
</nav>      
</div>  

这是这部分的控制器代码

$data['DPT'] = '<a href="'.base_url('index.php/cart/indexPT').'">Português</a>'; 
$data['DEN'] = '<a href="'.base_url('index.php/cart/indexEN').'">English</a>'; 
$data['DES'] = '<a href="'.base_url('index.php/cart/indexES').'">Español</a>'; 
//------------------ FOOTER              ----------------------
$data['footercontactUS'] = '<a href="'.base_url('index.php/cart/contactUS').'">Contacte-nos</a>';
$data['footeraboutUS'] = '<a href="'.base_url('index.php/cart/aboutUS').'">Sobre Nós</a>';
return $data;

更简单的方法是使用href的完整地址。

在您看来

<a href="https://www.example.com/index.php/cart/indexPT">Português</a>
