thinkphp3.2.3在視圖文件view中，如何獲得當(dāng)前的模塊名

           
<ul class="nav nav-second-level">
                <volist name="sinfo" id="vv"  >
                <if condition="$vv['parent_id'] == $vo['id']">
                <li>
                    <a class="J_menuItem" href="{:U('$vv['controller_name']')}" target="iframe0" data-index="0">{$vv['pri_name']}</a>
                    <ul class="nav nav-second-level">
                        <volist name="sinfo2" id="vvv"  >
                            <if condition="$vvv['parent_id'] == $vv['id']">
                            <li>
                                <a class="J_menuItem" href="{$smarty.const.__MODULE_NAME__}/{$vvv['controller_name']}/{$vvv['action_name']}" target="iframe0" data-index="0">{$vvv['pri_name']}</a>
                            </li>
                            </if>
                        </volist>
                     </ul>
                </li>
                </if>
                </volist>
            </ul>

我的版本是3.2.3
在視圖文件中的a標(biāo)簽的U函數(shù)，如何才能獲得當(dāng)前模塊名字。我當(dāng)前的模塊名是Admin的，我是想通過(guò)U函數(shù)拼接一個(gè)index.php/Admin/controller_xxxx/action_xxxx的url，下面我試了幾個(gè)方法也不行

{:U('__MODULE_NAME__/{$vv['controller_name']}/{$vv['action_name']}')}
