一、修改文件：\include\taglib目录下的channel.lib.php
<?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 ''; } $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From dede_arctype where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row"; } else if($type=="self") { if($reid==0) { return ''; } $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From `dede_arctype` where reid='$reid' And ishidden<>1 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 < $line;$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'], 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 .= "</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 ''; } $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From dede_arctype where reid='$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) $likeType .= "<dl>\r\n"; for($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; } ?>
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"> <div class="nav-l"> <a rel="nofollow noopener noreferrer" href="/"><span class="nav-l-span">顶级菜单<i></i></span> </a> <div class="nav-submenu"> <div id="submenu"> {dede:channelartlist typeid='72'} <div class="submenu1"> <h3 class="submenu1-t1"><a rel="nofollow noopener noreferrer" href="{dede:field name='typeurl'/}">{dede:field name='typename'/}</a></h3> </div> {/dede:channelartlist} </div> </div>
<div class="nav-submenu-xl">
{dede:channelartlist typeid='72'}
<div class="xl-menu" style="top:1px;display:none;">
<div class="xl-menu-l xl-menu-wc"> <div class="xl-menu-l-part">
{dede:channel type='son'}
<div id="xl-menu-l-div3"> <div class="xl-menu-l-div3-b">
<b> <a rel="nofollow noopener noreferrer" href="[field:typelink/]">[field:typename/]</a></b>
</div> <div class="xl-menu-l-div3-p">
<p>[field:sonchannel0] <a rel="nofollow noopener noreferrer" href="[field:typelink/]">[field:typename/]</a> |[/field:sonchannel0] </p> </div>
</div> {/dede:channel} </div> </div> </div> {/dede:channelartlist} </div> </div>
注：这里顶级菜单我调用了两次，大家按照自己的需求来！
