织梦如何调用四级栏目

天外飘仙

织梦调用四级子栏目，首先需要修改文件：\include\taglib目录下的channel.lib.php，请将以下代码全部复制替换上述文件：

1. <?php
   
2. function lib_channel(&$ctag,&$refObj)
   
3. {

7. extract($ctag->CAttribute->Items, EXTR_SKIP);
   
8. $innertext = $ctag->GetInnerText();
   
9. $cacheid = trim($cacheid);
   
10. if($cacheid !='') {

2、在模板中调用实例：

1. {dede:channel type='son' typeid='3'}
   
2. [field:typename/]
   
3. <ul>
   
4. [field:sonchannel0]
   
5. <li><a href="[field:typelink/]">[field:typename/]</a></li>
   
6. [field:sonchannel1]
   
7. <li><a href="[field:typelink/]">---[field:typename/]</a></li>
   
8. [field:sonchannel2]
   
9. <li><a href="[field:typelink/]">===[field:typename/]</a></li>
   
10. [field:sonchannel3]
    
11. <li><a href="[field:typelink/]">===[field:typename/]</a></li>
    
12. [/field:sonchannel3]
    
13. [/field:sonchannel2]
    
14. [/field:sonchannel1]
    
15. [/field:sonchannel0]
    
16. </ul>
    
17. {/dede:channel}
