DEDECMS中怎么获取无限栏目子分类
dedecms中怎么获取无限栏目子分类？
做企业网站大部分是使用DEDECMS，今天在给客户设计网站时，把DEDE自动内链和URL全拼格式搞定后，又遇到了个小问题，因为产品分类最多有四级，客户要求在左侧有个弹出式菜单调用各级子分类出来，而DEDECMS默认只能调用一级分类。经过努力，百度+GOOGLE+自己脑袋，终于搞定了这个东西，不敢独享，发出来给有需要的朋友分享。

首先要把/include/taglib/channerl.lib.php 文件的代码修改成以下的：
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 = $dsql->GetOne(“Select reid From ying_arctype where id=’$typeid’ “); if(is_array($dbrow)) $reid = $dbrow['reid']; } $likeType = ”; if($type==’top’) { $sql = “Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From ying_arctype where reid=0 And ishidden<>1 order by sortrank asc limit 0,$row”; } else if($type==”son”) { //if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid']; if($typeid==0) { return ”; } $sql = “Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From ying_arctype where reid=’$typeid’ And ishidden<>1 order by sortrank asc limit 0,$row”; } else if($type==”self”) { if($reid==0) { return ”; } $sql = “Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From ‘ying_arctype’ where reid=’$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) $likeType .= “<dl>\r\n”; for($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 ”; } $sql = “Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath,description From ying_arctype where reid=’$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; } ?>登录后复制
