DEDECMS中怎麼取得無限欄位子分類?
做企業網站大部分是使用DEDECMS,今天在為客戶設計網站時,把DEDE自動內鍊和URL全拼格式搞定後,又遇到了個小問題,因為產品分類最多有四級,客戶要求在左側有個彈出式選單呼叫各級子分類出來,而DEDECMS預設只能呼叫一級分類。經過努力,百度 GOOGLE 自己腦袋,終於搞定了這個東西,不敢獨享,發出來給有需要的朋友分享。

首先要把/include/taglib/channerl.lib.php 檔案的程式碼修改成以下的:
程式碼如下:
<?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; } ?>
在模板裡面用[field:sonchannel0] [/field:sonchannel0] 調用,這個是用來取子欄目用得(使用【sonchannel 數字】作為標籤名是為了防止嵌套的時候無法正確解析標籤),這個的作用就是當你的欄位有很多子欄目無限分級的時候方便你取子欄目的。實例一下:
程式碼如下:
<ul id="left_nav"> {dede:channel type='son' typeid='16'} <li><a href="[field:typelink/]“>[field:typename/]</a> <ul> [field:sonchannel0] <li><a href="[field:typelink/]“>[field:typename/]</a> <ul> [field:sonchannel1] <li><a href="[field:typelink/]“>[field:typename/]</a> <ul> [field:sonchannel2] <li><a href="[field:typelink/]“>[field:typename/]</a> <ul> [field:sonchannel3] <li><a href="[field:typelink/]“>[field:typename/]</a></li> [/field:sonchannel3] </ul> </li> [/field:sonchannel2] </ul> </li> [/field:sonchannel1] </ul> </li> [/field:sonchannel0] </ul> </li> {/dede:channel} </ul>
以上typeid中的數字改成你的大分類的ID即可,因為在DEDE官方論壇沒找到,所以這裡發上來,希望能方便有用者。
注意:未免出錯修改文件前請做好備份,以上程式碼可能有些引號又被自動轉成全角的了,請修改成半角的,或者可以找蕭涵索取此修改後的文件。
