Of course. Let's break down the DedeCMS tag {dede:arclist flag='h'}.

This is one of the most commonly used tags in DedeCMS for displaying content on the homepage.

Quick Summary

{dede:arclist flag='h'} is a DedeCMS tag that calls a list of articles that have been manually set as "Headlines" or "Highlights" in the DedeCMS后台 (backend/admin panel).

• {dede:arclist}: The main tag for calling a list of articles.
• flag='h': The parameter that filters the list to show only articles marked with the flag 'h'.

Detailed Breakdown

The Parent Tag: {dede:arclist}

This is the core tag for fetching article data from the database. It's highly versatile and can be customized with many parameters to control what articles are shown and how they are displayed.

Common parameters for {dede:arclist} include:

• typeid: (integer) Show articles from a specific category ID.
• row: (integer) The number of articles to display (e.g., row='10').len`: (integer) The length of the article title in characters.
• infolen: (integer) The length of the article summary (introtext).
• orderby: (string) Sort order (e.g., orderby='pubdate' by publish date, orderby='hot' by clicks/views).
• flag: (string) Filter by article flags.

The Parameter: flag='h'

The flag parameter is used to filter articles based on special markers assigned to them. The value 'h' specifically stands for "Headline".

How to assign the 'h' flag to an article:

1. Log in to your DedeCMS 后台 (backend/admin panel).
2. Go to "Content" -> "Add Article" ( -> 添加文档) or edit an existing article.
3. On the article editing page, look for the "Options" (选项) section, usually on the right side.
4. Find the "Flags" (推荐位) field. It's often a set of checkboxes or a dropdown.
5. Check the box for "Headline" (头条). The system internally uses the letter 'h' for this.
6. Save the article.

Now, any article with this "Headline" flag will be included in the results of {dede:arclist flag='h'}.
