怎么通过ajax传送json数组到php,并通过php将数据插入数据库

Jun 23, 2016 pm 01:17 PM

如题。本人刚开始学习php,基础并不好,百度了好久都无法实现,希望能给出例子。json数据是拼接得到的

1

<script>var fields = "[{ \"shop\":\"商店1\" , \"goods\":\"货物1\",\"price\":\"10 元\" },{\"shop\":\"商店2\" , \"goods\":\"货物2\",\"price\":\"11 元\" },{ \“shop\":\"商店3\" , \"goods\":\"货物3\",\"price\":\"13 元\”}]";  $.ajax({        type: "POST",        url : "1.php",        data: fields,        success: function(msg){          alert(msg);        }      });</script>t

Copy after login

1.php不会写

一般网站返回的格式是json POST提交的话 写成 “shop=%E5%95%86%E5%BA%971&goods=%E8%B4%A7%E7%89%A91&.....”(URL编码)

php里再获取 $shop= $_POST['shop'];
插入到数据库

首先你的 fields 写错了
不大可能用 js 代码去拼装 json 串,至少也是用 AJAX.stringify 方法来转换
要写作(断行看的清楚点)

1

var fields = [  { "shop":"商店1" , "goods\":"货物1","price":"10 元" },  { "shop":"商店2" , "goods":"货物2","price":"11 元" },  { “shop":"商店3" , "goods":"货物3","price":"13 元”}];

Copy after login

提交时

1

data: {fields:fields},

Copy after login

php 端 $_POST['fields'] 就是提交的数组

Json数组是获取table的数据拼接的,没有id,name之类的不知道怎么形成这种url编码

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,

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.

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.

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.

What is REST API design principles? What is REST API design principles? Apr 04, 2025 am 12:01 AM

RESTAPI design principles include resource definition, URI design, HTTP method usage, status code usage, version control, and HATEOAS. 1. Resources should be represented by nouns and maintained at a hierarchy. 2. HTTP methods should conform to their semantics, such as GET is used to obtain resources. 3. The status code should be used correctly, such as 404 means that the resource does not exist. 4. Version control can be implemented through URI or header. 5. HATEOAS boots client operations through links in response.

How do you handle exceptions effectively in PHP (try, catch, finally, throw)? How do you handle exceptions effectively in PHP (try, catch, finally, throw)? Apr 05, 2025 am 12:03 AM

In PHP, exception handling is achieved through the try, catch, finally, and throw keywords. 1) The try block surrounds the code that may throw exceptions; 2) The catch block handles exceptions; 3) Finally block ensures that the code is always executed; 4) throw is used to manually throw exceptions. These mechanisms help improve the robustness and maintainability of your code.

What are anonymous classes in PHP and when might you use them? What are anonymous classes in PHP and when might you use them? Apr 04, 2025 am 12:02 AM

The main function of anonymous classes in PHP is to create one-time objects. 1. Anonymous classes allow classes without names to be directly defined in the code, which is suitable for temporary requirements. 2. They can inherit classes or implement interfaces to increase flexibility. 3. Pay attention to performance and code readability when using it, and avoid repeatedly defining the same anonymous classes.
