40分求ThinkPHP循环嵌套打印出父类与子类的列表
大家好,我近段时间在学习thinkPHP框架,我想在模板页面实现循环打印出一个数据列表,格式是:先是父类类别名称,再接着打印出对应的子类列表,再接着打印另外一个父类名称,再打印该父类的对应的子类,以此类推。。。我是用表格排版,格式如:

    
  类别名      简介

  父类名称1   ......   
  子类名称1   .....   
  子类名称2   .....   
  子类名称3   .....   
  父类名称2   ......   
  子类名称1   .....   
  子类名称2   .....   
  子类名称3   .....   


  请问用volist该怎样实现,或者有没有更好的方法,请指教,感激不尽!!


------解决方案--------------------
使用地归来进行遍历就可以了

------解决方案--------------------
可以一试:第一次我都环找出所有parent_id然后记下该记录集的总量parent_count,然后以parent_count往下循环,以此类推……
------解决方案--------------------

<tbody>
<br><br>            <foreach><br>                <tr>
<br>                    <td>{$vo.depa_id}</td>
<br>                    <td>
<?php  if ($vo['depa_default'] == 1)<br />    echo '<b>[主页面]</b> '; ?><a>{$vo.depa_title}</a>
</td>
<br>                    <td>{$vo.label_count}</td>
<br>                    <td>{$vo.model_name}</td>
<br>                    <td>{$vo.depa_order}</td>
<br>                </tr>
<br>                <foreach><br>                    <tr>
<br>                        <td>{$son.depa_id}</td>

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
