Dedecms二级导航菜单的实现

Dedecms 默认的菜单为一级的(使用dede:channel标签),但是有很多项目需要实现多级菜单.

 

1. 在common.inc.php中定义一个全局变量: $wyq_menu

 

查询表获取菜单结构:

 

   父菜单1

  

    

子菜单1

    

    

子菜单2

    

    

子菜单3

  

 

 

   父菜单2

  

    

子菜单1

    

    

子菜单2

    

    

子菜单3

  

 

样例代码:

 

global $wyq_menu, $lang1, $news_link, $product_link, $swf_link;

$news_link = 'list.php?tid=1';
$product_link = 'list.php?tid=27';
$lang1 = (isset($tid) && is_numeric($tid) ? $tid : 1);
$swf_link = 'main.swf';

if($lang1) {
    $wyq_menu = getMenu($lang1);
}

function getMenu($lang1) {
    global $news_link, $product_link, $swf_link;
    $wyq_sql=new DedeSql(false);
    $wyq_sql0=new DedeSql(false);
    //获取语言
    while(1) {
        $inquery = "select * from #@__arctype where id=$lang1 and ishidden!=1";
        $wyq_sql->SetQuery($inquery);
        $wyq_sql->execute();
        if($row0 = $wyq_sql->GetArray()) {
            if($row0['reid'] != '0') {
                $lang1 = $row0['reid'];
                $tmp_ = explode('.swf', $row0['description']);
                if(count($tmp_) > 1) {
                    $swf_link = $row0['description'];
                }
            }
            else {
                $typelink1 = GetTypeUrl1($row0['id'],$row0['typedir'],$row0['isdefault'],
             $row0['defaultname'],$row0['ispart'],$row0['namerule2']);
                break;
            }
        }
    }
    
    $inquery = "select * from #@__arctype where reid=$lang1 and ishidden!=1 order by sortrank desc";
    $wyq_sql->SetQuery($inquery);
    $wyq_sql->execute();
    
    $wyq_menu = '

';
    while($row = $wyq_sql->GetArray()) {
        $typelink = GetTypeUrl1($row['id'],$row['typedir'],$row['isdefault'],
         $row['defaultname'],$row['ispart'],$row['namerule2']);
         $typename = $row['typename'];
         $f_link = $typelink;
         $f_name = $typename;
         $inquery = "select * from #@__arctype where reid=" . $row['id'] . " and ishidden!=1 order by sortrank";
         $wyq_sql0->SetQuery($inquery);
         $wyq_sql0->execute();
        
         $i = 0;
        
         while($row0 = $wyq_sql0->GetArray()) {
            $typelink = GetTypeUrl1($row0['id'],$row0['typedir'],$row0['isdefault'],
             $row0['defaultname'],$row0['ispart'],$row0['namerule2']);
             if($i == 0){
             $wyq_menu = $wyq_menu . '
• . $typelink . '">'. $typename .'';
           $wyq_menu = $wyq_menu . '
  ';
               }
               $typename = $row0['typename'];
           if($news_link != 'list.php?tid=29' && $row0['content']) {
           $c=explode('NEWS', $row0['content']);
           if(count($c) > 1) {
           $news_link = $typelink;
           continue;
           }
           }
           if($row0['content']){
           $c=explode('PRODUCTS', $row0['content']);
           if(count($c) > 1) {
           $product_link = $typelink;
           }
           }
           $wyq_menu = $wyq_menu . '
  • . $typelink . '">'. $typename .'
  ';
           $i = $i + 1;
           }
          
           if($i != 0) {
           $wyq_menu = $wyq_menu . '
  ';
           }
           else {
           $wyq_menu = $wyq_menu . '
• . $f_link . '">'. $f_name .'';
           }
          
           $wyq_menu = $wyq_menu . '
';
    }
    
    $wyq_menu = $wyq_menu . '
• . $typelink1 .'">' . ($lang1 == '1' ? '首页' : 'Home') . '
' . '

';
    return $wyq_menu;
}

//栏目目录规则
function MfTypedir1($typedir)
{
    if(eregi("^http:",$typedir)) return $typedir;
    $typedir = str_replace("{cmspath}",$GLOBALS['cfg_cmspath'],$typedir);
    $typedir = ereg_replace("/{1,}","/",$typedir);
    return $typedir;
}
//获得指定类目的URL链接
//对于使用封面文件和单独页面的情况，强制使用默认页名称
function GetTypeUrl1($typeid,$typedir,$isdefault,$defaultname,$ispart,$namerule2)
{
    $typedir = MfTypedir1($typedir);
    if($isdefault==-1)
    {
        //动态
        $reurl = $GLOBALS['cfg_phpurl']."/list.php?tid=".$typeid;
    }
    else if($ispart==2)
    {
        //跳转网址
        $reurl = $typedir;
        return $reurl;
    }
    else
    {
        if($isdefault==0 && $ispart==0)
        {
            $reurl = str_replace("{page}","1",$namerule2);
            $reurl = str_replace("{tid}",$typeid,$reurl);
            $reurl = str_replace("{typedir}",$typedir,$reurl);
        } else {
            $reurl = $typedir.'/'.$defaultname;
        }
    }

    if( !eregi("^http://",$reurl) ) {
        $reurl = ereg_replace("/{1,}",'/',$reurl);
    }
    
    return $reurl;
}

2. 在en/header.htm替换{dede:channel}为{dede:global name='wyq_menu'/}

3. 使用StuHover菜单
