提出问题:我希望首页的文章列表输出指定分类下的文章(被指定的分类输出,没被指定的分类不输出,另外是否能指定多个分类?),应该如何操作?
个人水平:简单的html(5没学)和css(3没学),PHP和Javascript没学。
一些描述:
我已经在sf的typecho区搜索过了,然后发现了这篇文章:《TYPECHO如果想输出某个分类的文章列表,这个列表需要带有文章图片该怎么操作》。
我按照答案,把<?php $this->widget('Widget_Archive@index', 'pageSize=6&type=category', 'mid=12')->to($categoryPosts); ?>
复制进“index.php”文件中,放置在<?php while($categoryPosts->next()): ?>
之上,然后修改mid,打开首页并没有我想要的效果。
另外我也在官方文档中看过一篇关于“调用某一分类下的文章”的文档,官方说这样调用:<?php $this->widget('Widget_Archive@myCustomCategory', 'type=category', 'mid=1')->to($categoryPosts); ?>
,然后操作“$categoryPosts”的变量,关于这个变量我也不知道如何操作= =

What’s still popular is the ease of use, flexibility and a strong ecosystem. 1) Ease of use and simple syntax make it the first choice for beginners. 2) Closely integrated with web development, excellent interaction with HTTP requests and database. 3) The huge ecosystem provides a wealth of tools and libraries. 4) Active community and open source nature adapts them to new needs and technology trends.

PHP and Python are both high-level programming languages that are widely used in web development, data processing and automation tasks. 1.PHP is often used to build dynamic websites and content management systems, while Python is often used to build web frameworks and data science. 2.PHP uses echo to output content, Python uses print. 3. Both support object-oriented programming, but the syntax and keywords are different. 4. PHP supports weak type conversion, while Python is more stringent. 5. PHP performance optimization includes using OPcache and asynchronous programming, while Python uses cProfile and asynchronous programming.

PHP is mainly procedural programming, but also supports object-oriented programming (OOP); Python supports a variety of paradigms, including OOP, functional and procedural programming. PHP is suitable for web development, and Python is suitable for a variety of applications such as data analysis and machine learning.

PHP originated in 1994 and was developed by RasmusLerdorf. It was originally used to track website visitors and gradually evolved into a server-side scripting language and was widely used in web development. Python was developed by Guidovan Rossum in the late 1980s and was first released in 1991. It emphasizes code readability and simplicity, and is suitable for scientific computing, data analysis and other fields.

PHP is suitable for web development and rapid prototyping, and Python is suitable for data science and machine learning. 1.PHP is used for dynamic web development, with simple syntax and suitable for rapid development. 2. Python has concise syntax, is suitable for multiple fields, and has a strong library ecosystem.

PHP remains important in the modernization process because it supports a large number of websites and applications and adapts to development needs through frameworks. 1.PHP7 improves performance and introduces new features. 2. Modern frameworks such as Laravel, Symfony and CodeIgniter simplify development and improve code quality. 3. Performance optimization and best practices further improve application efficiency.

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.
