The following editor will bring you an article on how to implement the accounting tree menu in ComboTree of ThinkPHP+EasyUI. The editor thinks it’s pretty good, so I’ll share it with you now and give it as a reference. Let’s follow the editor to take a look.

Assume that the fields of the accounting data table in the database are: id, code, name, islast. They are the auto-increment primary key, account code, account name, and whether it is the last-level account ("1" indicates the last-level account).

Here, recursion is used in the model layer of Thinkphp to build the data required by ComboTree. The code and annotations are as follows:

namespace Home\Model;
use Think\Model;

class AccountModel extends Model{

　　public function getTreeList(){  
  $data = $this->field(&#39;id,code,name,islast&#39;)->select(); 
  foreach($data as &$v){　　　　　　　 //这里加入了元素pid，用来标识父级id的　　　
   $len = strlen($v[&#39;code&#39;]);
   if($len == 3){　　　　　　　　　　//这里假设长度为3位的科目编码是一级,5位为二级科目，7位为三级，以此类推
    $v[&#39;pid&#39;] = 0; 
   } else {
    $v[&#39;pid&#39;] = substr($v[&#39;code&#39;],0,$len-2); 
   }  
  }
  return $this->createTree($data); //生成ComboTree所需的数据结构
 }
 
 //递归的方式生成子树
 private function createSubTree($data,$pid){
  $tree = array();
  foreach($data as $k=>$v){
   if($v[&#39;pid&#39;] == $pid){
    $newDate = array(
     &#39;id&#39; => $v[&#39;id&#39;],
     &#39;text&#39;=>$v[&#39;name&#39;],
     &#39;state&#39;=>($v[&#39;islast&#39;] != 1)?&#39;closed&#39;:&#39;open&#39;
    ); 
    if($v[&#39;islast&#39;] != 1){　　　　　　　　//如果不是末级科目调用自身生成子数据
     $subData = $this->createSubTree($data,$v[&#39;code&#39;]);
     if(!empty($subData)){
      $newDate[&#39;children&#39;] = $subData;  
     }
    }
    array_push($tree,$newDate);
   }   
  } 
  return $tree;
 }
 
 //生成树,先从一级会计科目分类开始创建树形菜单数据
 private function createTree($data){  
  $ret = array();
  foreach($data as $k => $v){
   if($v[&#39;pid&#39;] == 0){
    $newDate = array(  //创建为ComboTree能够识别的格式，这里我没有更好的办法了，只能这样处理
     &#39;id&#39; => $v[&#39;id&#39;],
     &#39;text&#39;=>$v[&#39;name&#39;],
     &#39;state&#39;=>&#39;closed&#39;
    ); 
    $subData = $this->createSubTree($data,$v[&#39;code&#39;]);
    if(!empty($subData)){
     $newDate[&#39;children&#39;] = $subData;  
    }
    $ret[] = $newDate; 
   }    
  }
  return $ret;
 }  
}

Data similar to the above (such as departments, regions, etc.) can basically achieve similar functions by simply modifying the code to build a tree menu.
