1.在page_header.lbi对应的位置（你想显示导航的位置）插入
(注意下面的”themes/模板名称/util.php”中的”模板名称”改成你模板文件夹的名称)
<?php
require_once(“themes/模板名称/util.php”);
?>
<div>
<p {if $navigator_list.config.index eq 1} {/if}><a href=”../index.php”>{$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 $nav.active eq 1}{/if}>
<a href=”{$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”>
//初始化主菜单
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.把以下代码编辑成(util.php)解压出来拷贝到模板目录下
<?php
/**
* 通过传入参数的url判断是否为目录分类，从而获取子菜单
* @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″;
$res = $GLOBALS[‘db’]->getAll($sql);
foreach($res as $idx => $row)
{
$cat_arr[$idx][‘id’] = $row[‘cat_id’];
$cat_arr[$idx][‘name’] = $row[‘cat_name’];
$cat_arr[$idx][‘url’] = build_uri(‘category’, array(‘cid’ => $row[‘cat_id’]), $row[‘cat_name’]);
$cat_arr[$idx][‘children’] = get_clild_list($row[‘cat_id’]);
}
return $cat_arr;
}
else
{
return false;
}
}
function get_clild_list($pid)
{
//开始获取子分类
$sql_sub = “select * from “.$GLOBALS[‘ecs’]->table(‘category’).” where parent_id=”.$pid.” and is_show=1″;
$subres = $GLOBALS[‘db’]->getAll($sql_sub);
if($subres)
{
foreach ($subres as $sidx => $subrow)
{
$children[$sidx][‘id’]=$subrow[‘cat_id’];
$children[$sidx][‘name’]=$subrow[‘cat_name’];
$children[$sidx][‘url’]=build_uri(‘category’, array(‘cid’ => $subrow[‘cat_id’]), $subrow[‘cat_name’]);
}
}
else
{
$children = null;
}
return $children;
}
?>
