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 = $this->field('id,code,name,islast')->select(); foreach($data as &$v){ //这里加入了元素pid,用来标识父级id的 $len = strlen($v['code']); 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['pid'] = 0; } else { $v['pid'] = substr($v['code'],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['pid'] == $pid){ $newDate = array( 'id' => $v['id'], 'text'=>$v['name'], 'state'=>($v['islast'] != 1)?'closed':'open' ); if($v['islast'] != 1){ //如果不是末级科目调用自身生成子数据 $subData = $this->createSubTree($data,$v['code']); if(!empty($subData)){ $newDate['children'] = $subData; } } array_push($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['pid'] == 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 'id' => $v['id'], 'text'=>$v['name'], 'state'=>'closed' ); $subData = $this->createSubTree($data,$v['code']); if(!empty($subData)){ $newDate['children'] = $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.
