ecshop简单三步实现导航商品分类二级菜单

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 class = h

 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 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"> 

      //初始化主菜单 

                function sw_nav(obj,tag) 

                { 

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

                        var ifs = obj.getElementsByTagName_r("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 

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; 

} 

?>
