HomeBackend DevelopmentPHP Tutorial二手房租房网那种条件筛选怎么通过PHP程序实现

类似58这种条件筛选通过PHP程序怎么实现呢,哪位告诉下,通过笨办法倒是可以实现,但是那种就是太耗时而且冗余代码还多,不知道哪位高手能有更好办法,谢谢!


回复讨论(解决方案)

怎么没人呢?

笨方法是什么方法?

这种需求,将筛选条件拼接起来就可以实现了, 比如没有任何条件的时候

select * from tbl_name where 1=1 


如果选择了一个区域,sql语句就变成

select * from tbl_name where 1=1 and area = ”XXX“ 


在选择一个方式, sql语句就变成

select * from tbl_name where 1=1 and area = ”XXX“ and type=1 


多种条件一直拼在sql语句后面就行了。

你可以考虑URL传参,也可以考虑直接写入cookie或者session进行操作,然后再针对存在的数据拼装sql。我是这么认为的,但是具体还是看需求。

看来回答的人很少啊

还是没人呢,哪位大侠帮帮忙吧,谢谢了

其实这个问题很大,服务端和客户端都涉及到了
服务端主要是如何生成查询语句
客户端如何确定传值的样式
而你什么具体要求都不说,难道然人加给你写本书?

ajax或者Frame点击一次提交一次

类似这样的形式?
那你可以组合拼装sql

楼主,具体的我都已经写出来了,现在主要就是数据拆分,可以到www.0971my.com/wskh.php上面看下

强烈建议  php+sphinx  你值得拥有

我以前弄过一个,你自己看看改下就行了

//删除GET参数if(isset($_GET['act'])) {  $k = substr($_GET['act'], 3);  unset($_GET['act']);  if($k == 'all') $_GET = array();  else unset($_GET[$k]);}/*获取GET参数*/function getparam($k) {  $param = $_GET;  if(isset($_GET[$k])) unset($param[$k]);  $param[$k] = '';  return http_build_query($param);}

这个$param用法,'.$quyu['title'].'
剩下的就是拼SQL语句了。

Dependency Injection in PHP: Code Examples for BeginnersDependency Injection in PHP: Code Examples for BeginnersMay 14, 2025 am 12:08 AM

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

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.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
