一、修改文件：\include\taglib目录下的channel.lib.php
function lib_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();
$cacheid = trim($cacheid);
if($cacheid !='') {
$likeType = GetCacheBlock($cacheid);
if($likeType != '') return $likeType;
}
$reid = 0;
$topid = 0;
if(empty($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 = $dsql->GetOne("Select reid From dede_arctype where id='$typeid' ");
if(is_array($dbrow)) $reid = $dbrow['reid',;
}
$likeType = '';
if($type=='top')
{
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl]sitepath,description
From dede_arctype where reid=0 And ishidden1 order by sortrank asc limit 0]$row";
}
else if($type=="son")
{
//if($_sys_globals['typeid',>0) $typeid = $_sys_globals['typeid',;
if($typeid==0) {
return '';
}
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl]sitepath,description

}
else if($type=="self")
{
if($reid==0) {
return '';
}
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl]sitepath,description
From `dede_arctype` where reid='$reid' And ishidden1 order by sortrank asc limit 0]$row";
}
//And id'$typeid'
$needRel = false;
$dtp2 = new DedeTagParse();
$dtp2->SetNameSpace("field","[",",");
$dtp2->LoadSource($innertext);
$dsql2 = clone $dsql;
$dsql->SetQuery($sql);
$dsql->Execute();
$line = $row;
//检查是否有子栏目，并返回rel提示（用于二级菜单）
if(ereg(':rel', $innertext)) $needRel = true;
if(empty($sql)) return '';
$dsql->SetQuery($sql);
$dsql->Execute();
$totalRow = $dsql->GetTotalRow();
$GLOBALS['autoindex', = 0;
for($i=0;$i
{
if($col>1) $likeType .= "\r\n";
for($j=0;$j
{
if($col>1) $likeType .= "\r\n";
if($row=$dsql->GetArray())
{
$row['sonids', = $row['rel', = '';
if($needRel)
{
$row['sonids', = GetSonIds($row['id',, 0] false);
if($row['sonids',=='') $row['rel', = '';
else $row['rel', = " rel='dropmenu{$row['id',}'";
}
//处理同级栏目中，当前栏目的样式
if( ($row['id',==$typeid || ($topid==$row['id', && $type=='top') ) && $currentstyle!='' )
{
if($currentstyle!='')
{
$linkOkstr = $currentstyle;
$row['typelink', = GetOneTypeUrlA($row);
$linkOkstr = str_replace("~rel~",$row['rel',,$linkOkstr);
$linkOkstr = str_replace("~id~",$row['id',,$linkOkstr);
$linkOkstr = str_replace("~typelink~",$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->CTags as $tagid=>$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 .= "\r\n";
$GLOBALS['autoindex',++;
}//Loop Col
if($col>1)
{
$i += $col - 1;
$likeType .= " \r\n";
}
}//Loop for $i
reset($dsql2);
$dsql->FreeResult();
return $likeType;
}
function lib_channel_son($ctag,$typeid = 0]$dsql2)
{
$attlist = "row|100]col|1,currentstyle|";
FillAttsDefault($ctag->CAttribute->Items,$attlist);
extract($ctag->CAttribute->Items, EXTR_SKIP);

$dsql3 = clone $dsql2;
$likeType = '';
//if($_sys_globals['typeid',>0) $typeid = $_sys_globals['typeid',;
if($typeid==0) {
return '';
}
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl]sitepath,description
From dede_arctype where reid='$typeid' And ishidden1 order by sortrank asc limit 0]$row";
//And id'$typeid'
$dtp2 = new DedeTagParse();
$dtp2->SetNameSpace("field","[",",");
$dtp2->LoadSource($innertext);
$dsql2->SetQuery($sql);
$dsql2->Execute();
$line = $row;
for($i=0;$i
{
if($col>1) $likeType .= "\r\n";
for($j=0;$j
{
if($col>1) $likeType .= "\r\n";
if($row=$dsql2->GetArray())
{
$row['typelink', = $row['typeurl', = GetOneTypeUrlA($row);
if(is_array($dtp2->CTags))
{
foreach($dtp2->CTags as $tagid=>$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) $likeType .= "\r\n";
}//Loop Col
if($col>1)
{
$i += $col - 1;
$likeType .= " \r\n";
}
}//Loop for $i
reset($dsql3);
$dsql2->FreeResult();
return $likeType;
}
?>
复制这个文件覆盖旧文件。
二：巧用sonchannel标签做三级菜单
{dede:channelartlist typeid='72'}
{/dede:channelartlist} //调用顶级栏目（一级菜单）
dede:channel type='son'}
{/dede:channel} //二级菜单
[field:sonchannel0]//无限获取三级菜单
实例：
div class="nav">
[url=,顶级菜单[i,[/i, [/url]
{dede:channelartlist typeid='72'}
[url=,{dede:field name='typename'/}[/url]
{/dede:channelartlist}
{dede:channelartlist typeid='72'}
{dede:channel type='son'}
[url=,[field:typename/,[/url]
[field:sonchannel0] [url=,[field:typename/,[/url] |[/field:sonchannel0]
{/dede:channel}
{/dede:channelartlist}
注：这里顶级菜单我调用了两次，大家按照自己的需求来！ |
