This article mainly introduces "how to realize the accounting subjects tree menu in the ComboTree of ThinkPHP+EasyUI". In the daily operation, I believe that many people have doubts about how to realize the accounting subjects tree menu in ThinkPHP+EasyUI ComboTree. Xiaobian consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the doubts of "how to realize the accounting subjects tree menu in ThinkPHP+EasyUI ComboTree". Next, please follow the editor to study!

Here, the data, code and comments needed to build ComboTree using recursion in the model layer of Thinkphp 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) {/ / the element pid is added here to identify the parent id's $len = strlen ($v [' code']) If ($len = = 3) {/ / it is assumed that 3-digit account codes are first-level, 5 second-level subjects, and 7 third-level subjects, and so on $v ['pid'] = 0;} else {$v [' pid'] = substr ($v ['code'], 0lnlum 2);}} return $this- > createTree ($data) / / generate the data structure required for ComboTree} / / generate subtree 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) {/ / if it is not a last-level account, call its own generated child data $subData = $this- > createSubTree ($data,$v [' code']); if (! empty ($subData)) {$newDate ['children'] = $subData;}} array_push ($tree,$newDate);} return $tree } / / spanning tree, starting with the first-level account classification, create the tree menu data private function createTree ($data) {$ret = array () Foreach ($data as $k = > $v) {if ($v ['pid'] = = 0) {$newDate = array (/ / create a format that ComboTree can recognize, here I have no better choice but to deal with' id' = > $v ['id'],' text'= > $v ['name'],' state'= > 'closed'); $subData = $this- > createSubTree ($data,$v [' code']) If (! empty ($subData)) {$newDate ['children'] = $subData;} $ret [] = $newDate;}} return $ret;}}

Similar to the above data (such as departments, regions, etc.) need to build a tree menu of simple modification code can basically achieve similar functions.

At this point, the study on "how to realize the accounting subjects tree menu in the ComboTree of ThinkPHP+EasyUI" is over. I hope to be able to solve your doubts. The collocation of theory and practice can better help you learn, go and try it!
