织梦如何调用四级栏目

概述织梦调用四级子栏目，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： ?php function lib_channel($ctag,$refObj) { global $_sys_globals,$envs,$dsql; $attlist = typeid|0,reid|0,row|100,col|1,type|son 织梦调用四级子栏目，首先需要修改文件：\include\taglib目录下的channel.lib.PHP，请将以下代码全部复制替换上述文件：   <?PHP function lib_channel(&$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') $sql = "Select ID,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From dede_arctype where reID=0 And ishIDden<>1 order by sortrank asc limit 0,$row"; else if($type=="son") //if($_sys_globals['typeID']>0) $typeID = $_sys_globals['typeID']; if($typeID==0) { return ''; From dede_arctype where reID='$typeID' And ishIDden<>1 order by sortrank asc limit 0,sans-serif; Font-size: 15px; line-height: 25px;"> else if($type=="self") if($reID==0) { From `dede_arctype` where reID='$reID' And ishIDden<>1 order by sortrank asc limit 0,sans-serif; Font-size: 15px; line-height: 25px;"> //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 ''; $totalRow = $dsql->GetTotalRow(); $GLOBALS['autoindex'] = 0; for($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()) $row['sonIDs'] = $row['rel'] = ''; if($needRel) $row['sonIDs'] = GetSonIDs($row['ID'],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'],sans-serif; Font-size: 15px; line-height: 25px;"> $linkOkstr = str_replace("~typelink~",$row['typelink'],sans-serif; Font-size: 15px; line-height: 25px;"> $linkOkstr = str_replace("~typename~",$row['typename'],sans-serif; Font-size: 15px; line-height: 25px;"> $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())) $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,sans-serif; Font-size: 15px; line-height: 25px;"> $dsql3 = clone $dsql2; $dsql2->Setquery($sql); $dsql2->Execute(); if($row=$dsql2->GetArray()) reset($dsql3); $dsql2->FreeResult(); ?>

  2、在模板中调用实例： {dede:channel type='son' typeID='3'} [fIEld:typename/] <ul> [fIEld:sonchannel0] <li><a href="[fIEld:typelink/]">[fIEld:typename/]</a></li> [fIEld:sonchannel1] <li><a href="[fIEld:typelink/]">---[fIEld:typename/]</a></li> [fIEld:sonchannel2] <li><a href="[fIEld:typelink/]">===[fIEld:typename/]</a></li> [fIEld:sonchannel3] [/fIEld:sonchannel3] [/fIEld:sonchannel2] [/fIEld:sonchannel1] [/fIEld:sonchannel0] </ul> {/dede:channel}
