dede如何控制隐藏栏目的显示与调用
许多时候有些栏目想在某些页面隐藏，在另外一些页面显示，怎么办？
貌似，织梦的channel标签不能获取隐藏的栏目，于是我自己动手修改channel标签
首先找到include/taglib/channel.lib.php
1.
$attlist = "typeid|0,reid|0,row|100,col|1,type|son,currentstyle|,cacheid|";
修改为：
$attlist = "typeid|0,reid|0,row|100,col|1,type|son,currentstyle|,cacheid|,showhide|no";
2.
在这两句下 
    $innertext = $ctag->GetInnerText();
    $line = empty($row) ? 100 : $row;
增加：

01$showhideArr = array(
02 
03    'yes' => 0,
04 
05    'no' => 1,
06 
07    'both'=> -1,
08 
09);
10 
11$hideflag = $showhideArr[$showhide];

织梦中{dede:channel}无法调用隐藏栏目解决方法

01if($type=='top')
02 
03  {
04 
05      $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
06 
07        From `dede_arctype` WHERE reid=0 And ishidden<>1 order by sortrank asc limit 0, $line ";
08 
09  }
10 
11  else if($type=='son')
12 
13  {
14 
15      if($typeid==0) return '';
16 
17      $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
18 
19        From `dede_arctype` WHERE reid='$typeid' And ishidden<>1 order by sortrank asc limit 0, $line ";
20 
21  }
22 
23  else if($type=='self')
24 
25  {
26 
27      if($reid==0) return '';
28 
29      $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
30 
31          FROM `dede_arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line ";
32 
33  }

修改为：

02 
03 {
04 
05     $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
