php向mysql插入数据传空值问题

Jun 23, 2016 pm 02:05 PM

我记得可以向mysql传空值插入数据

sql语句写成这样“insert into uer (id,name,pass) values('','李四','123')”
其中,id是主键,自增长。

我记得在配置文件中设置一下,可以让php执行的时候传空值,但是忘记是设置哪里了,麻烦知道的告诉一下。

自增长你怎么空值呢?骚年


“insert into uer (name,pass) values('李四','123')”

id子增长的插入空的肯定出错了
删掉即可,即:insert into uer (name,pass) values('李四','123')

id自增,肯定是int类型的呀!怎么可能用字符串形式来增加呢
id不用写就可以 
insert into uer (name,pass) values('李四','123')

是可以的,我前面设置成功过,现在忘记在配置文件哪一项了,php100视频里面也这么干过,不过没说设置哪里

都不知道你在说什么
你的代码不就是吗

是可以的,我前面设置成功过,现在忘记在配置文件哪一项了,php100视频里面也这么干过,不过没说设置哪里
好像有这么一说,但是我也忘记的。

解决了,在mysql的配置文件中,将默认不能传空值的地方改一下就可以了
默认为sql-mode="STRICT_TRANS_TABLES,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION",

将其修改为sql-mode="NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION"

哎,真心伤不起,为什么非要改呢?为这么一个去改配置?
那网上单吊虚拟空间你改不了的你怎么办、

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

Session hijacking can be achieved through the following steps: 1. Obtain the session ID, 2. Use the session ID, 3. Keep the session active. The methods to prevent session hijacking in PHP include: 1. Use the session_regenerate_id() function to regenerate the session ID, 2. Store session data through the database, 3. Ensure that all session data is transmitted through HTTPS.

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.
