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!!
回复讨论(解决方案)
汗,你知道他的父类和子类都有什么内容吗?
使用地归来进行遍历就可以了
狗屁框架
CodeIgniter,这个框架谁用过,现在想采访下你,说说你的使用后的感言!你的一言都影响后背
(lz不好意思,我没有积分了,只能占用你的了)
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……
<tbody> <foreach name="list" item="vo" > <tr rel="{$vo.depa_id}" target="depa_id"> <td>{$vo.depa_id}</td> <td><?php if ($vo['depa_default'] == 1) echo '<b>[主页面]</b> '; ?><a href="__BASEURL__/mudidi/{$vo.dein_id}/{$vo.depa_id}.html" target="_blank">{$vo.depa_title}</a></td> <td>{$vo.label_count}</td> <td>{$vo.model_name}</td> <td>{$vo.depa_order}</td> </tr> <foreach name="vo.son" item="son" > <tr rel="{$son.depa_id}" target="depa_id"> <td>{$son.depa_id}</td> <td><img src="/static/imghw/default1.png" data-src="http://bbs.phpchina.com/images/default/tree_linemiddle.gif" class="lazy" style="max-width:90%" alt="|-" title="|-" /><a href="__BASEURL__/mudidi/{$vo.dein_id}/{$vo.depa_id}.html" target="_blank">{$son.depa_title}</a></td> <td>{$son.label_count}</td> <td>{$son.model_name}</td> <td>{$son.depa_order}</td> </tr> </foreach> </foreach> </tbody>
模板里面不好递归,比较好的方式是在程序逻辑里递归出大致的树结构,模板里控制样式。
还不不太明白啊,有没有更详细的解决办法?
我其实就是要实现这么个效果:
输出一个父类和子类的列表:
如图:有谁能教我具体怎么做啊,谢谢!
求高手指点!!!!
用关联模型
<volist name="list" id="vo"> <tr><td>{$vo.typeName}</td><td>{$vo.typeDescription}</td></tr> <volist name="vo.depat" id="value"> <tr><td>{$value.typeName}</td><td>{$value.typeDescription}</td></tr> </volist></volist>
这个一般是配合MYSQL做的,通常在数据库设置好的,先是设置父类跟子类同一字段VAL ,然后子类再添加个保存父类ID的字段,然后WEB页面循环出来就行了
还需要吗?我有办法!
可以参考我这个筛选框,当然希望从中找到使用递归的灵感。这离递归不远了,原谅我比较懒。

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

The application of SOLID principle in PHP development includes: 1. Single responsibility principle (SRP): Each class is responsible for only one function. 2. Open and close principle (OCP): Changes are achieved through extension rather than modification. 3. Lisch's Substitution Principle (LSP): Subclasses can replace base classes without affecting program accuracy. 4. Interface isolation principle (ISP): Use fine-grained interfaces to avoid dependencies and unused methods. 5. Dependency inversion principle (DIP): High and low-level modules rely on abstraction and are implemented through dependency injection.

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.
