When a reader visits an article of interest, they often hope to browse related or continuous content seamlessly, rather than returning to the list page to search again.Provide navigation links to "Previous" and "Next" pages on the article detail page of the website, which is an effective way to enhance this reading experience and increase user stickiness.It can not only guide users to explore the website content in depth, but can also optimize the internal link structure of the website to some extent, and is friendly to search engines.
AnQiCMS (AnQiCMS) is a powerful content management system that fully considers the needs of content operation, and therefore provides a very convenient way to implement this function at the template tag level.Even if you are not familiar with complex programming, you can easily add navigation for the previous and next articles on your article detail page by calling simple tags.
Understanding the template mechanism of Anqi CMS
The AnQi CMS adopts a template engine syntax similar to Django, which means you can control the display logic and output data through specific tags. Template tags are usually followed by{% ... %}Wrap, used for control logic (such as conditional judgment, loop), and variable output is used{{ ... }}. The links and titles of the previous and next articles are implemented through the built-in template tags of the system, which automatically search and return information about adjacent articles based on the order of the current article in the database.
Find the article detail template file
To add the navigation for the previous and next articles on the article detail page, you first need to find the corresponding template file for the article detail page. In AnQi CMS, template files are usually stored in/templateIn the directory of the theme you are currently using.
Generally, the template file path of the article detail page will be similar./template/[你的模板目录]/[你的模型table]/detail.htmlThe structure. For example, if your article uses the "article" model and the template directory name isdefault, then the file may be intemplate/default/article/detail.html.
You can edit or download these template files online through the "Template Design" feature of the AnQi CMS backend to make modifications.
Add the previous and next navigation links: Core code implementation
AnQi CMS provides two special tags for obtaining information about the previous and next articles:prevArchive(Tags of the previous document) andnextArchive(Next document tag). These tags are very smart, they do not require additional parameters to automatically identify the current article and try to retrieve the data of the previous or next article.
Information obtained from these tags is an object containing multiple fields, from which you can extract the article ID, title, link, thumbnail, etc. Common fields include:
Id: Unique identifier of the articleTitle: Article titleLink: Access link of the articleThumb: Thumbnail address of the article (if available)Description: Article Summary
The following is an example of code to add previous and next navigation links to the article detail page:
<div class="article-navigation">
<div class="prev-article">
{% prevArchive prev %} {# 将上一篇文章信息赋值给变量prev #}
{% if prev %} {# 判断是否存在上一篇文章 #}
<a href="{{ prev.Link }}" title="{{ prev.Title }}">
<span class="navigation-direction">« 上一篇</span>
<h3 class="navigation-title">{{ prev.Title }}</h3>
{% if prev.Thumb %} {# 如果有缩略图，则显示 #}
<img src="{{ prev.Thumb }}" alt="{{ prev.Title }}" class="navigation-thumbnail"/>
{% endif %}
</a>
{% else %}
<span class="navigation-direction no-more">« 没有了</span>
{% endif %}
{% endprevArchive %}
</div>
<div class="next-article">
{% nextArchive next %} {# 将下一篇文章信息赋值给变量next #}
{% if next %} {# 判断是否存在下一篇文章 #}
<a href="{{ next.Link }}" title="{{ next.Title }}">
<span class="navigation-direction">下一篇 »</span>
<h3 class="navigation-title">{{ next.Title }}</h3>
{% if next.Thumb %} {# 如果有缩略图，则显示 #}
<img src="{{ next.Thumb }}" alt="{{ next.Title }}" class="navigation-thumbnail"/>
{% endif %}
</a>
{% else %}
<span class="navigation-direction no-more">没有了 »</span>
{% endif %}
{% endnextArchive %}
</div>
</div>

{% prevArchive prev %}and{% nextArchive next %}Load the data of the previous article and the next article separately intoprevandnextthe variable.{% if prev %}and{% if next %}This condition judgment is very important. It ensures that links are only rendered when there is indeed a previous or next article.If not found, it will display a prompt text like 'Not available', to avoid the page showing empty links.- The link
