As a senior website operations expert, I know that a smooth reading experience is crucial when users browse content.A good document detail page should not only display the core content but also guide users to take the next step, such as reading related content, or easily switching to the previous or next article.This not only improves the user's stay time on the website and reduces the bounce rate, but is also SEO-friendly, helping search engines to better crawl and understand the website structure.
In AnQiCMS, implementing the navigation links for the previous and next pages of the document detail page is a relatively simple but effective feature.It cleverly utilizes built-in template tags and logical judgments, significantly enhancing the interactivity and user experience of the website.
Elegant navigation mechanism: Understanding the intelligent tags of AnQiCMS
The template system of AnQiCMS is based on Django template engine syntax, providing a rich set of built-in tags, whereprevArchiveandnextArchiveIt is specifically designed to handle document navigation. The subtlety of these two tags is that they do not simply return a boolean value (yes/no existence), but are more intelligent:
- If it existsThe previous or next document, it will return a document object containing detailed information about the document,document object(for example, document ID, title, link, etc.).
- If it does not existThe corresponding documents, they will return an empty value (or it can be understood as)
nil).
It is based on this feature that we can easily make conditional judgments in the template to determine whether to display navigation links. These tags are usually found on the document detail page (for examplearchive/detail.htmlorproduct/detail.html）used, they will automatically identify their “neighbor” documents based on the current document's sorting within its category.
Implementation steps: Add navigation links on the document detail page.
To add the navigation links for the previous and next articles on your AnQiCMS website document detail page, you need to edit the corresponding template file. Below, I will elaborate on the operation steps:
First, find your document detail page template. This is usually located in the directory of the theme you are currently using.archive/detail.html(For article model) orproduct/detail.html(For product model) and other paths.
接下来，我们将巧妙地运用English CMS提供的prevArchiveandnextArchive这两个内置标签。这些标签会尝试获取当前文档的上一篇和下一篇文档信息。
The key is to add conditional judgment. Whenprev(or}nextThe variable is not empty, which means there is a corresponding previous (or next) document. At this point, we can safely accessprev.Linkandprev.TitleThis attribute is used to construct navigation links. If the document does not exist, we can also choose to display a prompt message, such as 'None' or guide the user back to the list.
The following is a clear template code example that shows how to judge and display the previous and next navigation links on the document detail page:
{# 假设这是您的文档详情页模板，例如：theme_name/archive/detail.html #}
<div class="document-navigation">
<div class="prev-document">
{# 使用 prevArchive 标签尝试获取上一篇文档信息，并将其赋值给变量 'prev' #}
{% prevArchive prev %}
{% if prev %}
{# 如果 'prev' 变量不为空，说明存在上一篇文档，则显示导航链接 #}
<a href="{{ prev.Link }}" title="上一篇：{{ prev.Title }}">
« 上一篇：{{ prev.Title }}
</a>
{% else %}
{# 如果 'prev' 变量为空，说明没有上一篇文档，则显示提示信息 #}
<span>« 没有了</span>
{% endif %}
{% endprevArchive %}
</div>
<div class="next-document">
{# 使用 nextArchive 标签尝试获取下一篇文档信息，并将其赋值给变量 'next' #}
{% nextArchive next %}
{% if next %}
{# 如果 'next' 变量不为空，说明存在下一篇文档，则显示导航链接 #}
<a href="{{ next.Link }}" title="下一篇：{{ next.Title }}">
下一篇：{{ next.Title }} »
</a>
{% else %}
{# 如果 'next' 变量为空，说明没有下一篇文档，则显示提示信息 #}
<span>没有了 »</span>
{% endif %}
{% endnextArchive %}
</div>
</div>
{# 您可以在此处添加CSS样式来美化您的导航链接，例如： #}
{#
<style>
.document-navigation {
display: flex;
justify-content: space-between;
margin-top: 20px;
padding: 10px 0;
border-top: 1px solid #eee;
}
.prev-document, .next-document {
flex: 1;
text-align: center;
padding: 5px 10px;
}
.prev-document a, .next-document a {
color: #007bff;
text-decoration: none;
}
.prev-document a:hover, .next-document a:hover {
text-decoration: underline;
}
.prev-document span, .next-document span {
color: #999;
}
</style>
#}
Tips for improving user experience
On top of the basic code, you can also make some personalized optimizations according to the overall style of the website and user needs:
- Visual presentation: For
.prev-documentand.next-documentAdd appropriate CSS styles, such as using icons (likeFont Awesomearrow icons) to make the navigation area more prominent and beautiful. - Thumbnail displayIf you want the navigation link to be more than just text, you can also consider adding a document thumbnail to the link.
prevandnextThe object also providesThumbproperties ({{ prev.Thumb }}), which can be used to display preview images. - Return list linkWhen there is no previous or next article, in addition to displaying 'none', you can also replace it with a link to 'return to the list' or 'return to the category homepage' to further guide users and avoid dead ends.This can be realized through additional conditional judgments, such as judging the link of the current document's category.

prevandnextThe variable returns a document object that contains rich field information, such asId/Title/Link/CreatedTime(Timestamp) andThumb（Thumbnail URL）。You can directly access these properties in the template to build a more detailed navigation. For example, you can display the publication date using{{ stampToDate(prev.CreatedTime, "2006-01-02") }}Format the timestamp, if a thumbnail is displayed, it can be used directly<img src="{{ prev.Thumb }}" alt="{{ prev.Title }}" />.Q: If my document detail page is the only document under a certain category, what will be displayed in the previous and next navigation areas?A: In this case, since
prevArchiveandnextArchiveLabel cannot find the corresponding document, they return theprevandnextAll variables will be empty.According to the template code provided above, the navigation area will display "‹ Nothing ›" and "Nothing ›".You can choose to display different prompt texts according to your design, or even hide the navigation area completely, or replace it with a link to 'Return to List' to provide a better user experience.
