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
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 = $ctag->GetInnerText();
if(empty($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 = $dsql->GetOne("Select reid From <a href="https:/cms/mailto:`dede_arctype">`dede_arctype</a>` where id='$typeid' ");
if(is_array($dbrow)) $reid = $dbrow['reid'];
}
$likeType = '';
if($type=='top')
{
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,description
From <a href="https:/cms/mailto:`dede_arctype">`dede_arctype</a>` where reid=0 And ishidden<>1 order by sortrank asc limit 0,$row";
}
else if($type=="son")
{
//if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid'];
if($typeid==0) {
return '';
}
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,description
From <a href="https:/cms/mailto:`dede_arctype">`dede_arctype</a>` where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row";
}
else if($type=="self")
{
if($reid==0) {
return '';
}
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,description
From <a href="https:/cms/mailto:`dede_arctype">`dede_arctype</a>` where reid='$reid' And ishidden<>1 order by sortrank asc limit 0,$row";
}
//And id<>'$typeid'
$dtp2 = new DedeTagParse();
$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->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 .= "</dd>\r\n";
$GLOBALS['autoindex']++;
}//Loop Col
if($col>1)
{
$i += $col - 1;
$likeType .= " </dl>\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 '';
}
$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,description
From <a href="https:/cms/mailto:`dede_arctype">`dede_arctype</a>` where reid='$typeid' And ishidden<>1 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 < $line;$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->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) $likeType .= "</dd>\r\n";
}//Loop Col
if($col>1)
{
$i += $col - 1;
$likeType .= " </dl>\r\n";
}
}//Loop for $i
reset($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:channel typeid='1'}
<li>
<a class="" href="https:/cms/[field:typeurl/]" title="">[field:typename/]
<img src="https:/cms/***.gif" /></a>
<div class="sub">
<ul>
[field:sonchannel0]<li><a href="https:/cms/[field:typeurl/]">[field:typename/]</a></li>[/field:sonchannel0]
</ul>
</div>
</li>
{/dede:channel}
