使用thinkphp遇到的小问题
刚接触thinkphp不久,遇到一个小问题,希望大家及时帮我解决,谢谢……

我在action中将数组传递到了页面中,进行循环显示,数组中有个价格数据,我想每次循环的时候累积起这个价格,在循环外面使用,不知道怎么定义??????????


------解决方案--------------------
用JS来做吧,docment ready的时候把显示出来的东西加一遍,显示在你要显示的inner里
------解决方案--------------------
在action中先累加存到变量中,调用模板的时候把这个值也传递过去就可以了

这个我也想过,不过这不是降低了效率吗?

你觉得这样效率会比你在显示的时候加了之后再用js插进值低吗?
模板就是用来显示的,而逻辑是在action里面完成的

怎么没人来看帖了,楼上的确解决我要的问题,但现在又有新问题了,我就是要在循环中才做处理的,如果不定义变量真的觉得一点都不方便,难道这是thinkphp不足吗????

那用2楼的方法做就可以了
------解决方案--------------------
万能且伟大的TP怎么可能做不好?

<php>$str='';</php><br />
<php><br />
    foreach($arr as $v)<br />
    {<br />
        $str+=$v;<br />
    }<br />
</php><br />
<php><br />
    echo $str;<br />
</php>

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

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.

SecLists

SecLists is the ultimate security tester's companion. It is a collection of various types of lists that are frequently used during security assessments, all in one place. SecLists helps make security testing more efficient and productive by conveniently providing all the lists a security tester might need. List types include usernames, passwords, URLs, fuzzing payloads, sensitive data patterns, web shells, and more. The tester can simply pull this repository onto a new test machine and he will have access to every type of list he needs.
