制作思路：
现在基于web2.0的下拉菜单 多是以
<ul>
<li>
<a>一级菜单</a>
<ul>
<li>
<a>二级级菜单</a>
</li>
</ul>
</li>
</ul>
这样的格式来实现的。但是dede的{dede:channel}标签是无法实现这个效果的，或者只有添加typeid这个参数来手工实现下拉菜单，这样的效果耗时耗力。
于是觉得只有改底层模板来实现了，高了一个小时以后增加了标签
{dede:channeli row='' type='top'}
{typelink:root}<li><a href="[field:typelink/]">[field:typename/]</a><ul>[field:child/]</ul></li>{/typelink:root}
{typelink:children}<li><a href="[field:typelink/]">[field:typename/]</a></li>{/typelink:children}
{/dede:channeli}
其实就是一个嵌套的标签
{typelink:root}<li><a href="[field:typelink/]">[field:typename/]</a><ul>[field:child/]</ul></li>{/typelink:root}
是父菜单的innertext
{typelink:children}<li><a href="[field:typelink/]">[field:typename/]</a></li>{/typelink:children}
是子菜单的innertext
由于系统的消耗，目前就支持两级 ，其实已经够用了!
这里相信大家已经看懂了思路了，下面就是修改办法：
include/inc_typelink.php
增加函数：
function GetChanneli($typeid=0,$reID=0,$row=8,$typetype='sun',$innertext='',$myinnertext='')
{
if($typeid==0) $typeid = $this->TypeID;
if($row=="") $row = 8;
if($reID=="") $reID = 0;
if($col=="") $col = 1;
if($typetype=="") $typetype="sun";
if($innertext=="") $innertext = GetSysTemplets("channel_list.htm");
if($reID==0 && $typeid>0){
$dbrow = $this->dsql->GetOne("Select reID From cmsxx_arctype where ID='$typeid' ");
if(is_array($dbrow)) $reID = $dbrow['reID'];
}
$likeType = "";
if($typetype=="top"){
$sql = "Select ID,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl
From cmsxx_arctype where reID=0 And ishidden<>1 order by sortrank asc limit 0,$row";
}
else if($typetype=="sun"||$typetype=="son"){
$sql = "Select ID,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl
From cmsxx_arctype where reID='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row";
}
else if($typetype=="self"){
$sql = "Select ID,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl
From cmsxx_arctype where reID='$reID' And ishidden<>1 order by sortrank asc limit 0,$row";
}
//扩展二级菜单
//主菜单的innertext
$root="";
//带有子菜单的innertext
$rootc="";
//子菜单的innertext
$children="";
$dtp3 = new DedeTagParse();
$dtp3->SetNameSpace("typelink","{","}");
$dtp3->LoadSource($innertext);
if(is_array($dtp3->CTags))
{
foreach($dtp3->CTags as $tagid=>$ctag )
{
$tagname=$ctag->GetName();
if($tagname=="root")
{
$root=$ctag->GetInnerText();
}
else if($tagname=="rootc")
{
$rootc=$ctag->GetInnerText();
}
else if($tagname=="children")
{
$children=$ctag->GetInnerText();
}
}
}
$dtp2 = new DedeTagParse();
$dtp2->SetNameSpace("field","[","]");
$dtp2->LoadSource($root);
$dsqli=new DeDeSql(fasle);
$dsqli->SetQuery($sql);
$dsqli->Execute();
$line = $row;
for($i=0;$i<$line;$i++)
{
if($row=$dsqli->GetArray())
{
if($typetype=="self" && $row['ID']=="$typeid"){
if($myinnertext!=''){
$linkOkstr = $myinnertext;
$row['typelink'] = $this->GetOneTypeUrl($row);
$linkOkstr = str_replace("~typelink~",$row['typelink'],$linkOkstr);
$linkOkstr = str_replace("~typename~",$row['typename'],$linkOkstr);
$likeType .= $linkOkstr;
}
}else{
//
$row['child']=$this->GetChannelList($row['ID'],0,18,$typetype='sun',$children,0,100,'','');
//
$row['typelink'] = $this->GetOneTypeUrl($row);
if(is_array($dtp2->CTags)){
foreach($dtp2->CTags as $tagid=>$ctag)
{ if(isset($row[$ctag->GetName()])) $dtp2->Assign($tagid,$row[$ctag->GetName()]); }
}
$likeType .= $dtp2->GetResult();
}
}
$GLOBALS['autoindex']++;
}
$this->dsql->FreeResult();
return $likeType;
}//GetChannel
在inc_archives_view.php，inc_arclist_view.php，inc_arcpart_view.php增加标签的解析
else if($tagname=="channeli"){
//获得栏目连接列表
if(trim($ctag->GetAtt('typeid'))=="" && $this->TypeID!=0){
$typeid = $this->TypeID;
$reid = $this->TypeLink->TypeInfos['reID'];
}
else{
$typeid = $ctag->GetAtt("typeid"); $reid=0;
}
$this->dtp->Assign($tagid,
$this->TypeLink->GetChanneli($typeid,$reid,$ctag->GetAtt("row"),
$ctag->GetAtt("type"),$ctag->GetInnerText(),"")
);
}
先后就交给系统来实现效果了
