ThinkPHP使用volist模板赋值问题

Jun 23, 2016 pm 01:25 PM

今天看代码遇到个问题,给模板赋值是用

assign('变量名','变量值')
Copy after login
完成的吧,模板那边
<volist name="变量名" id="循环量">xxx        </volist>
Copy after login


但是我遇到了变量名好像不一样啊。
<ul class="main-nav">        <volist name="__MENU__.main" id="menu">        <li class="{$menu.class|default=''}"><a href="{$menu.url|U}">{$menu.title}</a></li>        </volist>    </ul>
Copy after login

$this->assign('__MENU__', $this->getMenus());
Copy after login


这个多出来的.main是个啥?新人求解答

相当于__MENU__['main'],它应该是个数组,就是你用$this->getMenus()获取到的

相当于__MENU__['main'],它应该是个数组,就是你用$this->getMenus()获取到的


对啊,是数组,那不是应该直接把数组里的挨个取出来吗?__MENU__是表示整个数组啊。

我试着这么理解您看对不对哈。
getMenus()返回的数组里面,只把键为[main]的一组进行循环赋值。

__MENU__是一个数组,__MENU__.main也就相当于__MENU__['main']
再说的明白一点,假设数组$a=array('main'=>array(1,2,3)),$a.main也就是$a['main'],也就是array(1,2,3)。

__MENU__是一个数组,__MENU__.main也就相当于__MENU__['main']
再说的明白一点,假设数组$a=array('main'=>array(1,2,3)),$a.main也就是$a['main'],也就是array(1,2,3)。



0~懂了,
那为什么不写成
assign(__MENU__,getMenus().main)
Copy after login
php可以这样写不。。。?

php5.4+ 可以这样

assign(__MENU__,getMenus()['main'])
Copy after login

若小php5.4版本
就这样
$tmp=getMenus();assign(__MENU__,$tmp['main'])
Copy after login

Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Explain JSON Web Tokens (JWT) and their use case in PHP APIs. Apr 05, 2025 am 12:04 AM

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,

Describe the SOLID principles and how they apply to PHP development. Describe the SOLID principles and how they apply to PHP development. Apr 03, 2025 am 12:04 AM

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.
