How to add parent column calls and multi-level support for currentstyle in DEDECMS?
Because I needed it, I modified the code myself and shared it with friends who can use it. You can learn from it!

\include\inc_typelink.php
1. After this code (about 263 lines)
if($reID==0 && $typeid>0){ $dbrow = $this->dsql->GetOne("Select reID From dede_arctype where ID='$typeid' "); if(is_array($dbrow)) $reID = $dbrow['reID']; }
Add
// 新增代码 if($reID>0){ $dbrow = $this->dsql->GetOne("Select reID From dede_arctype where ID='$reID'"); if(is_array($dbrow)) $parentID = $dbrow['reID']; } // 新增代码结束结束
2. Then after the following code:
else if($typetype=="self"){ $sql = "Select ID,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl From dede_arctype where reID='$reID' And ishidden<>1 order by sortrank asc limit 0,$row"; }
Add
else if($typetype=="parent"){ //新增代码 获得上级栏目 $sql = "Select ID,typename,typedir,isdefault,ispart,defaultname,namerule2,moresite,siteurl From dede_arctype where reID='$parentID' And ishidden<>1 order by sortrank asc limit 0,$row"; } //新增代码结束 获得上级栏目
3. Modify the following code
if($row['ID']=="$typeid" && $myinnertext != ''){
Modify For:
if(($row['ID']=="$typeid" || $row['ID']=="$reID" || $row['ID']=="$parentID") && $myinnertext != ''){
After 3 steps of modification
can achieve 2 functions:
1. Call the parent column (superior), the column classification is too deep Useful
methods:
{dede:channel type='parent'}{dede:channel}
2. You can call currentstyle, which is very useful if the column classification is too deep and you want to change the current column style!
