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。

PHP is used to build dynamic websites, and its core functions include: 1. Generate dynamic content and generate web pages in real time by connecting with the database; 2. Process user interaction and form submissions, verify inputs and respond to operations; 3. Manage sessions and user authentication to provide a personalized experience; 4. Optimize performance and follow best practices to improve website efficiency and security.

PHP uses MySQLi and PDO extensions to interact in database operations and server-side logic processing, and processes server-side logic through functions such as session management. 1) Use MySQLi or PDO to connect to the database and execute SQL queries. 2) Handle HTTP requests and user status through session management and other functions. 3) Use transactions to ensure the atomicity of database operations. 4) Prevent SQL injection, use exception handling and closing connections for debugging. 5) Optimize performance through indexing and cache, write highly readable code and perform error handling.

Using preprocessing statements and PDO in PHP can effectively prevent SQL injection attacks. 1) Use PDO to connect to the database and set the error mode. 2) Create preprocessing statements through the prepare method and pass data using placeholders and execute methods. 3) Process query results and ensure the security and performance of the code.

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

PHP is widely used in e-commerce, content management systems and API development. 1) E-commerce: used for shopping cart function and payment processing. 2) Content management system: used for dynamic content generation and user management. 3) API development: used for RESTful API development and API security. Through performance optimization and best practices, the efficiency and maintainability of PHP applications are improved.

PHP makes it easy to create interactive web content. 1) Dynamically generate content by embedding HTML and display it in real time based on user input or database data. 2) Process form submission and generate dynamic output to ensure that htmlspecialchars is used to prevent XSS. 3) Use MySQL to create a user registration system, and use password_hash and preprocessing statements to enhance security. Mastering these techniques will improve the efficiency of web development.

PHP and Python each have their own advantages, and choose according to project requirements. 1.PHP is suitable for web development, especially for rapid development and maintenance of websites. 2. Python is suitable for data science, machine learning and artificial intelligence, with concise syntax and suitable for beginners.

PHP is still dynamic and still occupies an important position in the field of modern programming. 1) PHP's simplicity and powerful community support make it widely used in web development; 2) Its flexibility and stability make it outstanding in handling web forms, database operations and file processing; 3) PHP is constantly evolving and optimizing, suitable for beginners and experienced developers.
