DEDECMS列表页调用当前栏目父级栏目的方法

天外飘仙

本文实例讲述了DEDECMS列表页调用当前栏目父级栏目的方法。分享给大家供大家参考。具体实现方法如下：
修改方法如下
首先找到如下代码:

代码如下:

1. if($type=='top')
   
2. {
   
3. $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
   
4. From `dede_arctype` WHERE reid=0 And ishidden<>1 order by sortrank asc limit 0, $line ";
   
5. }
   
6. else if($type=='son')
   
7. {
   
8. if($typeid==0) return '';
   
9. $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
   
10. From `dede_arctype` WHERE reid='$typeid' And ishidden<>1 order by sortrank asc limit 0, $line ";
    
11. }
    
12. else if($type=='self')
    
13. {
    
14. if($reid==0) return '';
    
15. $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
    
16. FROM `dede_arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line ";
    
17. }

复制代码

然后将下面代码拷贝到其后面:

代码如下:

1. else if($type=='topone')
   
2. {
   
3. if($reid==0) return '';
   
4. $rowR = $dsql->GetOne("SELECT * FROM `dede_arctype` WHERE id='$typeid' ");
   
5. $topids = $rowR['topid'];
   
6. $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
   
7. FROM `dede_arctype` WHERE reid='0' And id='$topids' And ishidden<>1 order by sortrank asc limit 0, $line ";
   
8. }
   
9. else if($type=='fatherlist')
   
10. 
    
11. {
    
12. 
    
13. $rowR = $dsql->GetOne("SELECT * FROM `dede_arctype` WHERE id='$typeid' ");
    
14. $reid = $rowR['reid'];
    
15. $rowR = $dsql->GetOne("SELECT * FROM `dede_arctype` WHERE id='$reid' ");
    
16. $reid = $rowR['reid'];
    
17. $sql = "SELECT id,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl,sitepath
    
18. FROM `dede_arctype` WHERE reid='$reid' And ishidden<>1 order by sortrank asc limit 0, $line ";
    
19. }

复制代码

说明topone是调用当前目录对应的顶级目录'fatherlist' 是调用上一级目录,当前目录对应的顶级目录标记:
代码如下:

{dede:channel type='topone'}[field:typename/]{/dede:channel}

这个方法绝对可以,如果想用链接的话,就要[field:typeurl].
希望本文所述对大家的dedecms建站有所帮助。
