HomeBackend DevelopmentPHP Tutorialdiscuz关于发帖数据保存功能


discuz发帖有个机制,当发送中断后,会自己保存数据,当下次登录的时候,出现:您有上次未提交成功的数据 恢复数据

我想学习这个功能。

请问是ajax保存到数据库?还是存到cookie什么的?


请指教主要是哪些代码就可以了,我自己去学学。


回复讨论(解决方案)

1.如果特别重要的或者需要长时间编辑的内容    建议 setinterval ajax  保存用户的草稿信息到数据库(memcache、redis更好)  这样也可以实现夸浏览器
2.如果不重要的,判断用户浏览器是否支持HTML5的localStorage  保存在localStorage    如果是不支持的存储在cookie   但是cookie保存数据不要太多  因为每个请求都会传递cookie  

第一种方式  可以参考博客系统

Dependency Injection vs. Service Locator in PHPDependency Injection vs. Service Locator in PHPMay 13, 2025 am 12:10 AM

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

PHP Dependency Injection: Improve Code TestabilityPHP Dependency Injection: Improve Code TestabilityMay 12, 2025 am 12:03 AM

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
