dede 子栏目获取上级、顶级栏目的名字和链接

---

在DEDE根目录/include/taglib/下找到channel.lib.php文件找到

 

else if($type=='self')

{

if($reid==0) return '';

$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath

From `wmd_arctype` where reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line ";

}

 

然后，在此段代码下加入如下代码，为{dede：channel}添加父级(parent)栏目属性

 

else if($type=='parent')

{

$sql = "Select id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath

From `wmd_arctype` where id='$reid' AND ishidden<>1 order by sortrank asc limit 0, $line ";

}

 

然后用下面的就行了

 

<!--调用当前栏目的顶级栏目名称-->

{wmd:channel type='parent' }

[field:typename/]

{/wmd:channel}

 

dede 子栏目获取上级、顶级栏目的名字和链接

 

上面的方法当 当前栏目就是顶级栏目时候会失效，所以需要用到下面的方法【非无限子栏目】

 

{wmd:field.typeid runphp='yes'}$ID = @me; $sql = "SELECT * FROM `wmd_arctype` WHERE id=$ID";$query = mysql_query($sql);$row=mysql_fetch_array($query); $relID = "$row[reid]"; if($relID == 0) {@me = $row[typename];}else{$sql = "SELECT `typename` FROM `wmd_arctype` WHERE id=$relID";$query = mysql_query($sql);$row=mysql_fetch_array($query); @me = $row[typename];}{/wmd:field.typeid}

 

下面是顶级栏目的ID【非无限子栏目】

 

{wmd:field.typeid runphp='yes'}$ID = @me; $sql = "SELECT * FROM `wmd_arctype` WHERE id=$ID";$query = mysql_query($sql);$row=mysql_fetch_array($query); $relID = "$row[reid]"; if($relID == 0) {@me = $row[id];}else{$sql = "SELECT `id` FROM `wmd_arctype` WHERE id=$relID";$query = mysql_query($sql);$row=mysql_fetch_array($query); @me = $row[id];}{/wmd:field.typeid}

 

 

下面是无限子栏目获取顶级栏目资料的方法，不过下面的实例是获取顶级栏目下，的第二个栏目的方法，不过要获取顶级栏目的话，更简单，所做修改即可。

 

{wmd:field.typeid runphp='yes'}

$ID = @me;

$sql = "SELECT * FROM `wmd_arctype` WHERE id=$ID";

$query = mysql_query($sql);

$row=mysql_fetch_array($query);

$relID = $row[reid];

$jishu;

while($relID != 0){

$jishu = $row[id];

$sql = "SELECT * FROM `wmd_arctype` WHERE id=$relID";

$query = mysql_query($sql);

$row=mysql_fetch_array($query);

$relID = $row[reid];

}

$sql = "SELECT * FROM `wmd_arctype` WHERE id=$jishu";

$query = mysql_query($sql);

$row=mysql_fetch_array($query);

@me = $row[arcpic];

{/wmd:field.typeid}
