 dede5.7 動態導航下拉菜單的代碼實例

  本文介紹一個在dedecms5.7中實現動態導航下拉菜單的代碼實例，供大家學習參考。 1、修改include/taglib文件夾中的channel.lib.php文件，替換為如下內容：     <?php /**  * 動態導航下拉菜單  * Edit www.genban.org  * Date 2015-5-3 */ 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 = $dsql->GetOne("Select reid From <a href="mailto:`dede_arctype">`dede_arctype</a>` where id='$typeid' "); if(is_array($dbrow)) $reid = $dbrow['reid']; } $likeType = ''; if($type=='top') { $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,description From <a href="mailto:`dede_arctype">`dede_arctype</a>` where reid=0 And ishidden<dede后臺模板>1 order by sortrank asc limit 0,$row"; } else if($type=="son") { //if($_sys_globals['typeid']>0) $typeid = $_sys_globals['typeid']; if($typeid==0) { return ''; } $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,description From <a href="mailto:`dede_arctype">`dede_arctype</a>` where reid='$typeid' And ishidden<>1 order by sortrank asc limit 0,$row"; } else if($type=="self") { if($reid==0) { return ''; } $sql = "Select id,typenam織夢模板下載e,typedir,isdefault,ispart,defaultname,namerule2,description From <a href="mailto:`dede_arctype">`dede_arctype</a>` where reid='$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) //處理同級欄目中，當前欄目的樣式 { if($currentstyle!='') { $linkOkstr = $currentstyle; $row['typelink'] = Gdede免費模板etOneTypeUrlA($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 ''; } $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,description From <a href="mailto:`dede_arctype">`dede_arctype</a>` where reid='$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; } ?>     2、調用示例   {dede:channel typeid='1'} <li> <a class="" href="[field:typeurl/]" title="">[field:typename/] <img src="***.gif" /></a> <div class="sub"> <ul> [field:sonchannel0]<li><a href="[field:typeurl/]">[field:typename/]</a></li>[/field:sonchannel0] </ul> </div> </li> {/dede:channel}  相關織夢模板免費dede模板免費。
