首先需要修改文件:\include\taglib目录下的channel.lib.php,请将以下代码全部复制替换上述文件:
 
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 '';
}
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
From dede_arctype where reid='$typeid' And ishidden1 order by sortrank asc limit 0,$row";
}
else if($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!='' )
{

{

$row['typelink'] = GetOneTypeUrlA($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);
$innertext = $ctag->GetInnerText();
$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 .= "

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;
}
?>


 
2、在模板中调用实例:
 
{dede:channel type='son' typeid='3'}
[field:typename/]
    [field:sonchannel0]
    [field:sonchannel1]
    [field:sonchannel2]
    [field:sonchannel3]
    [/field:sonchannel3]
    [/field:sonchannel2]
    [/field:sonchannel1]
    [/field:sonchannel0]
     
    {/dede:channel}

    以上就是轻松调用织梦的四级栏目的全部内容了,你们都学会了吗?更多关于织梦教程,请继续关注爱站技术频道。
