1.在page_header.lbi對應(yīng)的位置（你想顯示導(dǎo)航的位置）插入

(注意下面的"themes/模板名稱/util.php"中的"模板名稱"改成你模板文件夾的名稱)

<?php

require_once("themes/模板名稱/util.php");

?>

<div class="header-menu">

<p {if $navigator_list.config.index eq 1} class="cur" {/if}><a href="../index.php">{$lang.home}</a></p>

<ul>

<!-- {foreach name=nav_middle_list from=$navigator_list.middle item=nav} -->

<li onMouseOver="sw_nav(this,1);" onMouseOut="sw_nav(this,0);" {if $nav.active eq 1} class="curs"{/if}>

<a href="{$nav.url}" {if $nav.opennew eq 1}target="_blank" {/if}>{$nav.name}</a>

<?php

$subcates = get_subcate_byurl($GLOBALS['smarty']->_var['nav']['url']);

if($subcates!=false)

{

if(count($subcates)>0)

{

echo "<div class='sub_nav'>";

if($subcates)

{

foreach($subcates as $cate)

{

echo "<a href='".$cate['url']."' class='level_1'>".$cate['name']."</a>";

}

}

echo "</div><iframe frameborder='0' scrolling='no' class='nomask'></iframe>";

}

}

?>

</li>

<!-- {/foreach} -->

</ul>

<script type="text/javascript">

//初始化主菜單

function sw_nav(obj,tag)

{

var subdivs = obj.getElementsByTagName("DIV");

var ifs = obj.getElementsByTagName("IFRAME");

if(subdivs.length>0)

{

if(tag==1)

{

subdivs[0].style.display = "block";

ifs[0].style.display = "block";

}

else

{

subdivs[0].style.display = "none";

ifs[0].style.display = "none";

}

}

}

</script>

</div>

2.在CSS文件中插入

.header-menu p{ float:left;padding:1px 12px 1px 0;margin-top:-2px;}

.header-menu ul li{float:left;padding:1px 12px 1px 12px;margin-top:-2px;}

.header-menu ul li a,.header-menu p a{color: #333;display:block;}

.header-menu ul li a:hover,.header-menu p a:hover{color:#888;}

.header-menu ul li.curs{background:#999;}

.header-menu ul li.curs a{color:#fff;}

.sub_nav{ background:#999;width:110px; position:absolute; z-index:5003; display:none;margin-left:-12px;}

.nomask{ background:#fff; width:110px; height:50px; position:absolute; z-index:5002;display:none;margin-left:-12px;}

.sub_nav a.level_1{ display:block;color:#fff;padding:6px 6px 6px 13px;font:11px Tahoma,Verdana,PMingLiU,Arial;border-bottom:1px dotted #D1D1D1;*border-bottom:1px dotted #D1D1D1 !important;*border-bottom:1px solid #A8A8A8;}

.sub_nav a.level_1:hover{color:#fff;background:#55B46C;text-decoration:none;}

3.把以下代碼編輯成(util.php)解壓出來拷貝到模板目錄下

<?php

/**

* 通過傳入?yún)?shù)的url判斷是否為目錄分類，從而獲取子菜單

*

* @param string $url

*/

function get_subcate_byurl($url)

{

$rs = strpos($url,"category");

if($rs!==false)

{

preg_match("//d+/i",$url,$matches);

$cid = $matches[0];

$cat_arr = array();

$sql = "select * from ".$GLOBALS['ecs']->table('category')." where parent_id=".$cid." and is_show=1";

以上就是ecshop簡單三部實(shí)現(xiàn)導(dǎo)航分類二級菜單的全部內(nèi)容。
