怎么根据smarty模板中定义的数字获取相应的新闻条数?

Jun 23, 2016 pm 02:15 PM

刚接触smarty模板,想在模板中控制显示的新闻条数,如下显示5条新闻

<ul>{section name=news loop=$arr max=5}	<li>{$arr[news].title}</li>{/section}</ul>
Copy after login


请问在php程序中怎么根据模板中的条数来读取相应的记录数?怎么获取模板中设置的条数?
从而实现下面的SQL:
SELECT id, title, wdate FROM news ORDER BY id DESC LIMIT 0, 5
Copy after login

而不是:
SELECT id, title, wdate FROM news ORDER BY id DESC
Copy after login

想取几条不是由你定吗? 直接写不就行了 ... limit 0,5

$smarty.section.loop.index 忘记是不是这个了。可以判断出当前运行的是第几条

$smarty.section.sectionname.index要么就是这个。 判断行数在1-5直接。否则不运行。楼主搜搜就知道了

<ul>{section name=news loop=$arr max=5}    <li>{$arr[news].title}</li>{/section}</ul>
Copy after login

不好意思,我没说明白,我的意思是php中怎么获取模板中定义的 max=5 ?

定义另一个变量,引入使用

定义另一个变量,引入使用
可以具体一点吗?刚接触,不知道怎么定义。

smarty 的循环是可以受控终止的,但应该不是你的这种写法

对 smarty 毫无兴趣!

知道了,确实不是我这种写法,一般都是在数据准备好后才去调用显示模板的。

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,

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.
