This update adds the tree menu function to the list page.
I wrote it directly on the list page.

The tree-like js code is plagiarized, and is mainly used to connect to the database.
Previously, the ztree plug-in with better results was used on the list page of the official website, but it was implemented based on jquery,
I still don't like jquery.


Update code

 
  
var data=[
  

  $sql="select bid,count(distinct bid),max(ssort) as st from " .C('db_prefix'). "small_block group by bid order by st desc";
  
$query=mysql_query($sql);
  
$num=mysql_num_rows($query);
  
if($num>0){
  
while($arr=mysql_fetch_array($query)){
  
$ssql="select * from " .C('db_prefix'). "big_block where id=".$arr['bid'];
  
$squery=mysql_query($ssql);
  
$snum=mysql_num_rows($squery);
