修改channel.lib.php实现DedeCMS多级栏目嵌套

前段时间做了个产品站,产品栏目分类为三级目录,客户想在前端将三级目录全部显示出来,而系统的channel标签只能获取下级分类,所以就报改了channel.lib.php这个文件,让他支持多级栏目嵌套,代码如下:
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 = $dsql->GetOne("Select reid From net_arctype where id='$typeid' ");
        if(is_array($dbrow)) $reid = $dbrow['reid'];
    }

    $likeType = '';
    if($type=='top')
    {
        $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
          From net_arctype where reid=0 And ishidden<>1 order by sortrank asc limit 0,$row";
    }
    else if($type=="son")
    {
        //if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid'];
        if($typeid==0) {
            return '';
        }
        $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
          From net_arctype where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row";
    }
    else if($type=="self")
    {
        if($reid==0) {
            return '';
        }
        $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description
            From `net_arctype` where reid='$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) $likeType .= "
"; for($j=0;$j<$col;$j++) { if($col>1) $likeType .= "
"; if($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 .= "
"; $GLOBALS['autoindex']++; }//Loop Col if($col>1) { $i += $col - 1; $likeType .= "
"; } }//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 ''; } $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From net_arctype where reid='$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 .= "

"; 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) $likeType .= "
"; }//Loop Col if($col>1) { $i += $col - 1; $likeType .= "
"; } }//Loop for $i reset($dsql3); $dsql2->FreeResult(); return $likeType; } ?>
将以上代码全部替换channel.lib.php文件内容后就可以了,附前端调用的示例:
{dede:channel type='top'}
[field:typename/]

{/dede:channel}
