$sql = "INSERT INTO patient (order,name,age,sex,tel,qq,disease,media_from,area,ordertime,teshuyaoqiu,content,ordertag,beizhu,zixun_id)					VALUES('$order','$name','$age','$tel','$qq','$disease','$media_from','$area','$ordertime','$teshuyaoqiu','$content','$ordertag','$beizhu','$zixun_id')";if (mysql_query ( $sql, $conn )) {	exit ( '添加成功!点击此处 <a href="../view/index.php">首页</a>' );} else {	echo '抱歉!添加数据失败:', mysql_error (), '<br />';	echo '点击此处 <a href="javascript:history.back(-1);">返回</a> 重试';}
Copy after login


运行结果:
抱歉!添加数据失败:You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'order,name,age,sex,tel,qq,disease,media_from,area,ordertime,teshuyaoqiu,content,' at line 1

order 是 mysql 保留字,挪作他用时应转义
`order`

要学会看错误报告
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near  'order,name,age,sex,tel,qq,disease,media_from,area,ordertime,teshuyaoqiu,content,' at line 1

引号后的就是 mysql 认为有问题的部分

两个问题
1.order是关键字,最好不要用。
如果一定要用,需要用``括起来。
2.insert的字段数量与后面的values数量不匹配
字段15个,但values只有14个,少了sex

改成这样就可以了。
$sql = "INSERT INTO patient ( `order `,name,age,sex,tel,qq,disease,media_from,area,ordertime,teshuyaoqiu,content,ordertag,beizhu,zixun_id)  VALUES('$order','$name','$age', '$sex','$tel','$qq','$disease','$media_from','$area','$ordertime','$teshuyaoqiu','$content','$ordertag','$beizhu','$zixun_id')";

使用order的时候,应该使用''

order 是 mysql 保留字,挪作他用时应转义
`order`


涨姿势了

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,

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.

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.
