dede5.7动态导航下拉菜单的实现代码

Dede5.7动态导航下拉菜单实现代码，需要的朋友可以参考一下。

1.修改include下面taglib文件夹里的channel.lib.php文件替换成我的

复制代码代码如下:
<?php
functionlib_channel(&$ctag,&$refObj)
{
global$_sys_globals,$envs,$dsql;
$attlist="typeid|0,reid|0,row|100,col|1,type|son,currentstyle|";
FillAttsDefault($ctag->CAttribute->Items,$attlist);
extract($ctag->CAttribute->Items,EXTR_SKIP);
$innertext=$ctag->GetInnerText();
if(empty($typeid)&&$envs['typeid']!=0)
{
$typeid=$envs['typeid'];
$reid=$envs['reid'];
}else{
$reid=0;
}
if($type==''||$type=='sun')$type="son";
if($innertext=='')$innertext=GetSysTemplets("channel_list.htm");
if($reid==0&&$typeid>0)
{
$dbrow=$dsql->GetOne("SelectreidFrom<ahref="mailto:`dede_arctype">`dede_arctype</a>`whereid='$typeid'");
if(is_array($dbrow))$reid=$dbrow['reid'];
}
$likeType='';
if($type=='top')
{
$sql="Selectid,typename,typedir,isdefault,ispart,defaultname,namerule2,description
From<ahref="mailto:`dede_arctype">`dede_arctype</a>`wherereid=0Andishidden<>1orderbysortrankasclimit0,$row";
}
elseif($type=="son")
{
//if($_sys_globals['typeid']>0)$typeid=$_sys_globals['typeid'];
if($typeid==0){
return'';
}
$sql="Selectid,typename,typedir,isdefault,ispart,defaultname,namerule2,description
From<ahref="mailto:`dede_arctype">`dede_arctype</a>`wherereid='$typeid'Andishidden<>1orderbysortrankasclimit0,$row";
}
elseif($type=="self")
{
if($reid==0){
return'';
}
$sql="Selectid,typename,typedir,isdefault,ispart,defaultname,namerule2,description
From<ahref="mailto:`dede_arctype">`dede_arctype</a>`wherereid='$reid'Andishidden<>1orderbysortrankasclimit0,$row";
}
//Andid<>'$typeid'
$dtp2=newDedeTagParse();
$dtp2->SetNameSpace("field","[","]");
$dtp2->LoadSource($innertext);
$dsql2=clone$dsql;
$dsql->SetQuery($sql);
$dsql->Execute();
$line=$row;
$GLOBALS['autoindex']=0;
for($i=0;$i<$line;$i++)
{
if($col>1)$likeType.="<dl>\r\n";
for($j=0;$j<$col;$j++)
{
if($col>1)$likeType.="<dd>\r\n";
if($row=$dsql->GetArray())
{
if($type=='self'&&$row['id']==$typeid)//处理同级栏目中，当前栏目的样式
{
if($currentstyle!='')
{
$linkOkstr=$currentstyle;
$row['typelink']=GetOneTypeUrlA($row);
$linkOkstr=str_replace("~typelink~",$row['typelink'],$linkOkstr);
$linkOkstr=str_replace("~typename~",$row['typename'],$linkOkstr);
$likeType.=$linkOkstr;
}
}else
{
$row['typelink']=$row['typeurl']=GetOneTypeUrlA($row);
if(is_array($dtp2->CTags))
{
foreach($dtp2->CTagsas$tagid=>$ctag){
if(isset($row[$ctag->GetName()]))
{
$dtp2->Assign($tagid,$row[$ctag->GetName()]);
}
elseif(preg_match('/^sonchannel[0-9]*$/',$ctag->GetName()))
{
$dtp2->Assign($tagid,lib_channel_son($ctag,$row['id'],$dsql2));
}
}
}
$likeType.=$dtp2->GetResult();
}
}
if($col>1)$likeType.="</dd>\r\n";
$GLOBALS['autoindex']++;
}//LoopCol
if($col>1)
{
$i+=$col-1;
$likeType.="</dl>\r\n";
}
}//Loopfor$i
reset($dsql2);
$dsql->FreeResult();
return$likeType;
}
functionlib_channel_son($ctag,$typeid=0,$dsql2)
{
$attlist="row|100,col|1,currentstyle|";
FillAttsDefault($ctag->CAttribute->Items,$attlist);
extract($ctag->CAttribute->Items,EXTR_SKIP);
$innertext=$ctag->GetInnerText();
$dsql3=clone$dsql2;
$likeType='';
//if($_sys_globals['typeid']>0)$typeid=$_sys_globals['typeid'];
if($typeid==0){
return'';
}
$sql="Selectid,typename,typedir,isdefault,ispart,defaultname,namerule2,description
From<ahref="mailto:`dede_arctype">`dede_arctype</a>`wherereid='$typeid'Andishidden<>1orderbysortrankasclimit0,$row";
//Andid<>'$typeid'
$dtp2=newDedeTagParse();
$dtp2->SetNameSpace("field","[","]");
$dtp2->LoadSource($innertext);
$dsql2->SetQuery($sql);
$dsql2->Execute();
$line=$row;
for($i=0;$i<$line;$i++)
{
if($col>1)$likeType.="<dl>\r\n";
for($j=0;$j<$col;$j++)
{
if($col>1)$likeType.="<dd>\r\n";
if($row=$dsql2->GetArray())
{
$row['typelink']=$row['typeurl']=GetOneTypeUrlA($row);
if(is_array($dtp2->CTags))
{
foreach($dtp2->CTagsas$tagid=>$ctag){
if(isset($row[$ctag->GetName()]))
{
$dtp2->Assign($tagid,$row[$ctag->GetName()]);
}
elseif(preg_match('/^sonchannel[0-9]*$/',$ctag->GetName()))
{
$dtp2->Assign($tagid,lib_channel_son($ctag,$row['id'],$dsql3));
}
}
}
$likeType.=$dtp2->GetResult();
}
if($col>1)$likeType.="</dd>\r\n";
}//LoopCol
if($col>1)
{
$i+=$col-1;
$likeType.="</dl>\r\n";
}
}//Loopfor$i
reset($dsql3);
$dsql2->FreeResult();
return$likeType;
}
?>

2.调用
这是我调用的代码

复制代码代码如下:
{dede:channeltypeid='1'}
<li>
<aclass=""href="[field:typeurl/]"title="">[field:typename/]
<imgsrc="***.gif"/></a>
<divclass="sub">
<ul>
[field:sonchannel0]<li><ahref="[field:typeurl/]">[field:typename/]</a></li>[/field:sonchannel0]
</ul>
</div>
</li>
{/dede:channel}
