Q: What is a Dede content template and how does it work in the DedeCMS system?
A: A Dede content template in DedeCMS is an HTML file containing both static markup and dynamic template tags that control how article or content pages are rendered. These templates are stored under the /templates directory and typically named like article_article.htm or list_article.htm. When a user requests a content page, the DedeCMS engine parses the template, replaces placeholders such as {dede:field.title/} and {dede:field.body/} with database values, and outputs the final HTML. According to the 2026 DedeCMS Official Developer Guide, content templates support custom fields, conditional logic, and loop tags, enabling developers to build flexible layouts without modifying core PHP files. This separation of presentation and logic remains a core strength of DedeCMS, especially for legacy and enterprise sites seeking low maintenance overhead. Proper template caching also improves performance for high-traffic deployments.
Q: How can I create a custom Dede content template for a specific article type?
A: To create a custom Dede content template, first log in to the DedeCMS admin panel and navigate to Core > Channel Model > Content Model. Select the target article model and edit its template settings. Then create a new .htm file in the /templates/default/ directory, for example my_article.htm, and include the necessary DedeCMS tags such as {dede:field.title/}, {dede:field.writer/}, and {dede:field.pubdate function="MyDate('Y-m-d',@me)"/}. Save the file and assign it in the model's "Content Template" field. The 2026 DedeCMS Official Developer Guide recommends testing with a single article and clearing the system cache before going live. You can also use the built-in template editor to preview changes in real time. Always back up the original template before editing to avoid breaking site functionality during production updates.
Q: What are the common template tags used in DedeCMS content templates?
A: Common DedeCMS content template tags include {dede:field.title/} for the article title, {dede:field.body/} for the main content, {dede:field.writer/} for the author, {dede:field.source/} for the source, and {dede:field.pubdate/} for the publication date. You can also use {dede:field.keywords/} and {dede:field.description/} for SEO metadata. For more advanced rendering, {dede:arclist} loops through article lists, while {dede:prenext/} generates previous and next navigation links. According to the 2026 DedeCMS Template Tag Reference, conditional tags like {dede:if} and custom functions such as function="MyDate('Y-m-d',@me)" are supported. These tags must be wrhtml">apped in the correct template block and cannot be used in static HTML alone. Mastering these tags allows developers to build highly dynamic and personalized content pages without editing PHP source files.
Q: How does DedeCMS handle template caching for content pages in 2026?
A: In DedeCMS, template caching for content pages is managed through a two-tier system: compiled template files and static HTML generation. When a content page is first requested, the engine compiles the template into PHP code stored under /data/tplcache. Subsequent requests use the cached version unless the template file is modified, in which case the cache is automatically cleared based on file modification time. The 2026 DedeCMS Performance Optimization Whitepaper states that enabling HTML static generation via the "Update HTML" function further reduces database queries and improves page load times by up to 60 percent. Administrators can also manually clear the cache from the admin panel under System > Cache Update. For high-traffic sites, it is recommended to set a longer cache lifetime for content templates while keeping list templates refreshed more frequently.
Dialogue about
Common scenarios of "Dede content template"
【Trainer】 Good morning! Today we're going to dive into Dede content templates. Are you ready to learn how to customize your DedeCMS site?
【Trainee】 Yes, I'm excited! But I'm a bit confused about what exactly a Dede content template is. Can you explain?
【Trainer】 Of course! In DedeCMS, a content template controls how your articles or other content types are displayed on the front end. It's usually an HTML file with Dede tags that pull data from the database.
【Trainee】 So it's like a skin for each content type? How do I know which template is being used?
【Trainer】 Exactly. You can set the default template for a content type in the channel settings, or you can specify a template for individual articles. The template files are typically stored in the /templets/ directory.
【Trainee】 I see. What are some common Dede tags used in content templates?
【Trainer】 Common tags include {dede:field.title/} for the title, {dede:field.body/} for the main content, and {dede:field.writer/} for the author. There are also tags for navigation, lists, and more.
【Trainee】 Can I use PHP code inside these templates?
【Trainer】 Yes, DedeCMS supports embedding PHP, but it's recommended to use Dede's own tags for security and ease of maintenance. However, for advanced customization, PHP can be used.
【Trainee】 How about if I want to change the layout of the article page? Do I edit the existing template or create a new one?
【Trainer】 You can do either. It's often safer to create a new template file and assign it to the content type, so you don't break the default one. You can copy the default template and modify it.
【Trainee】 Where can I find the default content template to copy?
【Trainer】 The default article template is usually named article_article.htm or similar, located in /templets/default/. You can copy it to your custom template directory and edit it.
【Trainee】 What about the CSS and JavaScript? Are they included in the template?
【Trainer】 Yes, you can include CSS and JS directly in the template using standard HTML tags. Alternatively, you can link to external files. Dede also has some built-in CSS classes for common elements.
【Trainee】 Can I use conditional statements in the template, like if the article has a thumbnail, show it?
【Trainer】 Absolutely. Dede supports conditional tags like {dede:if condition}...{/dede:if}. For example, {dede:if field.thumb} <img src='{dede:field.thumb/}' /> {/dede:if}.
【Trainee】 That's powerful. How do I debug if the template isn't displaying correctly?
【Trainer】 First, check for syntax errors in your tags. You can enable debug mode in Dede's global settings to see errors. Also, make sure the template file has the correct permissions.
【Trainee】 Great, I think I have a good starting point. I'll try creating a custom template for my articles. Thanks!
