1.一定要有哦
2.把SQL输出一下看下拼接是否正确

把各种 参数 提交 到服务器, 服务器程序拼接一下 SQL 语句,就OK 了

提交的时候,获取参数看看

一个就够了吧。其他的通过后台获取变量后再拼接SQL

具体怎么写呢,呵呵,,,还望指教。

<form id="search" target="_blank" action="<?php bloginfo('url'); ?>"/><input class="pinpai" type="text" name="pinpai" id="pinpai" value="品牌" onFocus="this.value='';" onBlur="if(this.value==''){this.value='品牌';}"/><input class="chexi" type="text" name="chexi" id="chexi" value="车系" onFocus="this.value='';" onBlur="if(this.value==''){this.value='车系';}"/><input class="jiage" type="text" name="jiage" id="jiage" value="价格范围" onFocus="this.value='';" onBlur="if(this.value==''){this.value='价格范围';}"/><input class="guanjianci" type="text" name="keyword" id="keyword" value="关键词" onFocus="this.value='';" onBlur="if(this.value==''){this.value='关键词';}"/>    <button class="search01" type="submit">搜索</button></form>	
Copy after login

把name和id都唯一,后台用$_POST['name']来取值

PHP code?1234567

"/>

初学,所以请教一下,关于这个$_POST['name']怎么写呢?拜托拜托!!在线等您。

$_POST['name']就是后台接收数据时候用的啊
name是你前面input框的name值
用这个试试吧
if(isset($_POST['name'])){
   echo $_POST['name'];
}


发送表单的方式分为post和get两种,在里这样设定

详细的可以去w3school看看

sql就能搞定了 $_post['文本框框名字']

sql就能搞定了 $_post['文本框框名字']

搞不定呀,请详细点好吗?谢谢。

w3school的教程参考下吧

如果所有input 的name都是"s",那post过去只能得到最后的那个值,也就是关键词的。需要将每个input的name都改成不一样,然后后台使用$_POST['input的name']取得对应的值

我只想知道具体怎么写。我是新手,实在不会呀。在线等。

如果是 使用Php做一个搜索框, 楼上已经给你了近乎详尽的做法了
如果是 使用wordpress程序做一个搜索框,那么你需要先阅读 wordpress 的插件开发说明书

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,

How does session hijacking work and how can you mitigate it in PHP? How does session hijacking work and how can you mitigate it in PHP? Apr 06, 2025 am 12:02 AM

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.

What are Enumerations (Enums) in PHP 8.1? What are Enumerations (Enums) in PHP 8.1? Apr 03, 2025 am 12:05 AM

The enumeration function in PHP8.1 enhances the clarity and type safety of the code by defining named constants. 1) Enumerations can be integers, strings or objects, improving code readability and type safety. 2) Enumeration is based on class and supports object-oriented features such as traversal and reflection. 3) Enumeration can be used for comparison and assignment to ensure type safety. 4) Enumeration supports adding methods to implement complex logic. 5) Strict type checking and error handling can avoid common errors. 6) Enumeration reduces magic value and improves maintainability, but pay attention to performance optimization.

Explain late static binding in PHP (static::). Explain late static binding in PHP (static::). Apr 03, 2025 am 12:04 AM

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.
