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--------------------
你不看他的手册吗?

Volist标签
Volist标签主要用于在模板中循环输出数据集或者多维数组。

通常模型的select和findall方法返回的结果是一个二维数组,可以直接使用volist标签进行输出。

在Action中首先对模版赋值:

$User = M('User');

$list = $User->select();

$this->assign('list',$list);

 

在模版定义如下,循环输出用户的编号和姓名:



{$vo.id}

{$vo.name}



Volist标签的name属性表示模板赋值的变量名称,因此不可随意在模板文件中改变。id表示当前的循环变量,可以随意指定,但确保不要和name属性冲突,例如:



{$data.id}

{$data.name}



支持输出部分数据,例如输出其中的第5~15条记录



{$vo.name}

PHP vs. Python: Understanding the DifferencesPHP vs. Python: Understanding the DifferencesApr 11, 2025 am 12:15 AM

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP: Is It Dying or Simply Adapting?PHP: Is It Dying or Simply Adapting?Apr 11, 2025 am 12:13 AM

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The Future of PHP: Adaptations and InnovationsThe Future of PHP: Adaptations and InnovationsApr 11, 2025 am 12:01 AM

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.

When would you use a trait versus an abstract class or interface in PHP?When would you use a trait versus an abstract class or interface in PHP?Apr 10, 2025 am 09:39 AM

In PHP, trait is suitable for situations where method reuse is required but not suitable for inheritance. 1) Trait allows multiplexing methods in classes to avoid multiple inheritance complexity. 2) When using trait, you need to pay attention to method conflicts, which can be resolved through the alternative and as keywords. 3) Overuse of trait should be avoided and its single responsibility should be maintained to optimize performance and improve code maintainability.

What is a Dependency Injection Container (DIC) and why use one in PHP?What is a Dependency Injection Container (DIC) and why use one in PHP?Apr 10, 2025 am 09:38 AM

Dependency Injection Container (DIC) is a tool that manages and provides object dependencies for use in PHP projects. The main benefits of DIC include: 1. Decoupling, making components independent, and the code is easy to maintain and test; 2. Flexibility, easy to replace or modify dependencies; 3. Testability, convenient for injecting mock objects for unit testing.

Explain the SPL SplFixedArray and its performance characteristics compared to regular PHP arrays.Explain the SPL SplFixedArray and its performance characteristics compared to regular PHP arrays.Apr 10, 2025 am 09:37 AM

SplFixedArray is a fixed-size array in PHP, suitable for scenarios where high performance and low memory usage are required. 1) It needs to specify the size when creating to avoid the overhead caused by dynamic adjustment. 2) Based on C language array, directly operates memory and fast access speed. 3) Suitable for large-scale data processing and memory-sensitive environments, but it needs to be used with caution because its size is fixed.

How does PHP handle file uploads securely?How does PHP handle file uploads securely?Apr 10, 2025 am 09:37 AM

PHP handles file uploads through the $\_FILES variable. The methods to ensure security include: 1. Check upload errors, 2. Verify file type and size, 3. Prevent file overwriting, 4. Move files to a permanent storage location.

What is the Null Coalescing Operator (??) and Null Coalescing Assignment Operator (??=)?What is the Null Coalescing Operator (??) and Null Coalescing Assignment Operator (??=)?Apr 10, 2025 am 09:33 AM

In JavaScript, you can use NullCoalescingOperator(??) and NullCoalescingAssignmentOperator(??=). 1.??Returns the first non-null or non-undefined operand. 2.??= Assign the variable to the value of the right operand, but only if the variable is null or undefined. These operators simplify code logic, improve readability and performance.
