This article mainly explains the implementation method of ThinkPHP and EasyUI's ComboTree to generate accounting account tree menu. Share it with everyone for reference. I hope to be helpful.
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; } }
Similar to the above Data (such as departments, regions, etc.) that need to build a tree menu can basically achieve similar functions by simply modifying the code.

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
