调用三级四级无限级栏目效果图

第一种自定义函数递归法

适用于前端简单样式用户，在 include/extend.func.php 最下面添加

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33

/** * 取出所有分类 * @param int $channel 频道ID * @return string www.dede58.com 织梦模板下载 * 调用{dede:global.getalltype function='getalltype()'/} */ function getalltype($channel=0,$line=10) { $line = empty($line) ? 10 : $line; global $dsql,$result; $dsql->SetQuery("SELECT id,typename,typenamedir,typelitpic,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `dede_arctype` WHERE reid='$channel' And ishidden<>1 order by sortrank asc limit 0, $line "); $dsql->Execute($channel); if($dsql->GetTotalRow($channel)>0) { $result .= "<ul>\r\n"; while($row = $dsql->GetArray($channel)) { $id = $row['id']; $typename = $row['typename']; $typelink = GetOneTypeUrlA($row); $result .= " <li>\r\n"; $result .= " <a href='{$typelink}' target='_blank'>{$typename}</a>\r\n"; getalltype($id,$line); $result .= " </li>\r\n"; } $result .= "</ul>\r\n"; } return $result; }

前台模板调用标签

{dede:global.getalltype function='getalltype()'/}

第二种标签嵌套法

适用于只调用出一级、二级、三级、四级的用户，直接在模板里写

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36

<ul> {dede:channelartlist row=7 typeid=top}  <li> <a href="{dede:field.typeurl/}" >{dede:field name='typename'/}</a> <ul> {dede:channel type=son noself=yes}  <li> <a href="[field:typeurl/]" title="[field:typename/]">[field:typename/]</a> <ul>  [field:id runphp=yes] global $dsql; $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `dede_arctype` WHERE reid=@me And ishidden<>1 order by sortrank asc limit 0,10"; $dsql->SetQuery($sql); $dsql->Execute('t'); $result = ''; while($row = $dsql->GetArray('t')) { $typename = $row['typename']; $typeurl = GetOneTypeUrlA($row); $result .= <<< TPL <li><a href="{$typeurl}">{$typename}</a></li> TPL; } @me = $result; [/field:id] </ul> </li> {/dede:channel} </ul> </li> {/dede:channelartlist} </ul>

上面的是输出到三级栏目，如果需要四级栏目可以这样写

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

[field:id runphp=yes] global $dsql; $sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `dede_arctype` WHERE reid=@me And ishidden<>1 order by sortrank asc limit 0,10"; $dsql->SetQuery($sql); $dsql->Execute('t'); $result = ''; while($row = $dsql->GetArray('t')) { $row['typeurl'] = GetOneTypeUrlA($row); $result .= "<a href='{$row[typeurl]}'>{$row[typename]}</a>"; //四级 $nsql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath FROM `dede_arctype` WHERE reid=$row[id] And ishidden<>1 order by sortrank asc limit 0,10"; $dsql->SetQuery($nsql); $dsql->Execute('n'); while($nrow = $dsql->GetArray('n')) { $nrow['typeurl'] = GetOneTypeUrlA($nrow); $result .= "<a href='{$nrow[typeurl]}'>{$nrow[typename]}</a>"; } } @me = $result; [/field:id]
