点评：dede5.7 动态导航下拉菜单的实现代码，需要的朋友可以参考一下

   1.修改 include下面taglib文件夹里的channel.lib.php文件 替换成我的

代码如下:

1. <?php
   
2. function lib_channel(&$ctag,&$refObj)
   
3. {
   
4. global $_sys_globals,$envs,$dsql;
   
5. $attlist = "typeid|0,reid|0,row|100,col|1,type|son,currentstyle|";
   
6. FillAttsDefault($ctag->CAttribute->Items,$attlist);
   
7. extract($ctag->CAttribute->Items, EXTR_SKIP);
   
8. $innertext = $ctag->GetInnerText();
   
9. if(empty($typeid) && $envs['typeid']!=0)
   
10. {
    
11. $typeid = $envs['typeid'];
    
12. $reid = $envs['reid'];
    
13. }else{
    
14. $reid=0;
    
15. }
    
16. if($type==''||$type=='sun') $type="son";
    
17. if($innertext=='') $innertext = GetSysTemplets("channel_list.htm");
    
18. if($reid==0 && $typeid>0)
    
19. {
    
20. $dbrow = $dsql->GetOne("Select reid From <a href="mailto:`dede_arctype">`dede_arctype</a>` where id='$typeid' ");
    
21. if(is_array($dbrow)) $reid = $dbrow['reid'];

2.调用
这是我调用的代码

代码如下:

1. {dede:channel typeid='1'}
   
2. <li>
   
3. <a class="" href="[field:typeurl/]" title="">[field:typename/]
   
4. <img src="***.gif" /></a>
   
5. <div class="sub">
   
6. <ul>
   
7. [field:sonchannel0]<li><a href="[field:typeurl/]">[field:typename/]</a></li>[/field:sonchannel0]
   
8. </ul>
   
9. </div>
   
10. </li>
    
11. {/dede:channel}
